Long Term Test: Canon 7D Vs Nikon D300s





Both the Nikon D300s and the Canon 7D have been reviewed in different situations and at different times. However, when a review is complete, there are still issues that arise with the cameras way afterward. After using both for a prolonged period of time, this is the posting that will weigh the pros and cons of each camera against one another after they have been used in conditions and situations that most users of these cameras will find themselves in. Further, problems that did not arise before will now be noted.

Complete Postings

Canon 7D

Night 1- The camera and two prime lenses documented a Jewish Seder during the week of Passover. It performed very well and users of this camera may be asked to actually join a family at dinner and document the happenings as they progress throughout the night.
Day 2- The 7D and 24-105mm F4 L IS went to the giant pillow fight in Union Square. While the FPS kept up, the autofocus couldn’t quite capture the quickly moving combatants at varying distances and at such as fast speed too. But it did withstand the punishment of elbows, heads, shoulders and pillows knocking it about. When the autofocus did work correctly, it captured some wonderful images. If you’re getting into a warzone like this, perhaps you’re better off with a 1D Mk IV.
With the Sun Sniper Camera StrapThis strap has replaced the Canon strap on my 7D as it typically holds my longer lenses during events and it’s also the camera I go to when I need to quickly capture something. Along with the 5D Mk II, I’ve run into nothing that the combined two can’t tackle.
Day 3- Testing at a get-together of NYC gaming journalists at a bar. Autofocus was fine in the dim light and mostly stagnant people. As was the high ISO ability shooting at ISO 3200 and above. All photos were shot in JPEG for truly showing the noise levels.
On the Set of a Podcast- The 7D performed much better in terms of manipulation vs the T2i. Noise levels in movie mode seemed to be the same.

Nikon D300s

This isn’t as fully detailed as the Canon review for the reason that this is around the time that the Field Reviews were just starting and didn’t start to evolve into the long and thorough discussions that they became. Admittedly though, much more time was spent with the D300s but enough time was spent with the D300s to make complete conclusions about the camera.

Autofocus

The original D300 blew its competition, the Canon 50D out of the water. In order to compete, Canon needed to totally revamp their autofocus system. While the systems are similar, they are still totally different beasts.
Both autofocus systems work best in still camera mode vs video mode. No company has created an effective solution to autofocusing in video at the time of writing this posting.
Both systems utilize different zones and areas to achieve focusing. To make a long story short, Nikon’s is smarter in full auto-focusing while allowing more maneuverability and faster access to settings on the fly in varying shooting situations. What’s its edge? For starters it allows to user to move the focusing points around using the back joystick. When a photographer is shooting, all that one needs to do is just move this point back and forth to the exact area that they want to focus on. A great example is sports, event or concert shooting. Also keep this in mind for when the kids are running around at the wedding reception.
Editor’s Note: After working with it on a photoshoot, I figured out how to unlock the previously said feature on the 7D. It’s something that most photographers would look past though, but works just as well as Nikon’s system. The fact that it is readily available on the Nikon though is very critical.
In contrast, one has to press a series of buttons on the 7D. If the 7D had allowed for the flexibility that the D300s did it would be game over. The reason for this is because of just how accurate and smart the zones and areas are to lock onto the subject that the photographer really wants to get.
Nikon fanboys can relax now.
Winner: Nikon D300s

Video Modes

Both the Canon 7D and the Nikon D300s shoot HD video. The quality of both is very good and for photojournalists, it should be enough for their purposes.
Here are the differences—the Canon 7D shoots 1080p HD video at 30p, 24p, and 25p. It also shoots 720p 60p video for users that need that specific look. Further, the camera can also shoot in standard definition mode. To top all this off, it has a switch on the back to put the DSLR into stills or video mode very quickly. Utilizing the back and front dials, the camera can be an excellent tool on the set of a video production.
The Nikon D300s shoots 720p HD video at 24p. It can also do this in VGA and QVGA modes—standard definition and mobile video.
When shooting, users will also see less of the dreaded, “jello effect” when using the 7D. To be fair, if you put an image stabilized lens on either camera, it will effectively eliminate this problem.
So which one is better? The 7D takes the cake here. The Dual DIGIC IV processors combined with the different video modes available and the noise control at the higher ISOs just take offer videographers, podcasters, photojournalists, wedding photographers and concert shooters so much more that they can offer to their clients—which further amounts to more of a monetary return. Further, the 7D offers full manual control over the image. Sadly, its flaw is little to no control over the sound. Keep this all in mind when you are on the video set of your next production.
In the end, we just want to see the pores on your face.
Winner: Canon 7D

Ergonomics

Right off the bat, the 7D is a more complicated beast of a camera. There are more buttons in different places that previous Canon users will need to get used to as it will require a rewiring of your muscle memory.
The D300s on the other hand feels exactly like the previous generation of cameras that came before it. To that end, users that are upgrading will have no trouble adapting. This will make a difference when shooting in situations that require hastiness on the photographer’s part.
The feel of both cameras are solid and unless there was some major fondling going on you probably would not be able to tell the difference.
Something that did bug me a bit was the fact that in order to change some settings on the D300s the photographer’s eye needs to leave the viewfinder at times. An example of this is the ISO settings. To be fair, the 7D also can have this problem unless the photographer really knows his/her way around the buttons when switching the autofocus settings.
Winner: Tie—they could both use some tweaks. Overall, they both feel the way that a camera should and definitely don’t feel like something that is meant for amateurs.

Durability

Both the 7D and the D300s are workhorses—make no mistake about that. They weren’t designed like the T2i to be for casual users and tourists. No, these cameras are for working photographers. And cameras for working photographers are built to be tough.
On both sides of the fence, the cameras are indeed tough. I’ve never dropped either one per se, but they have been subject to being in my messenger bag while traveling from venue to venue, on a crowded NYC subway, pushing their way through crowds, getting bumped by ravers and teens in the equivalent of a mosh pit filled with pacifists, etc.
As far as weatherproofing goes, the cameras will and should both be able to resist good amounts of rain and downpour. I know many photographers that are always afraid of rain hitting their cameras. For the most part, you can stop worrying about the weather being kryptonite to your camera.
So which one is better? They’re tied actually. At this spot in the product line, both cameras are essentially the same. Once you start moving up, you’ll see that Nikon takes the edge. I previously wrote that if someone tried to steal the D3s I was reviewing that I would beat them with it without any fear of breaking the camera.
Their skull on the other hand…
Winner: Tie

Image Quality

This is a bit of a tough one. In terms of color quality, you’re really not going to see much of a difference except if one shoots in JPEG mode.
When in JPEG mode, the D300s takes the cake for less noise. However, there is also less detail in the images because of the 12MP sensor vs Canon’s 18MP sensor.
In RAW mode, one really won’t be able to tell the difference between the two cameras unless you sit there everyday studying the way that the images are taken with both cameras in different situations. This becomes even more true with the use of modern day editing programs like Lightroom or Photoshop. The 7D can go up to ISO 6400 while the D300s can do ISO 3200. When shooting concerts or weddings, the latter could become a pain unless faster glass is attached. For best results, try some Nikkor primes or the 24-70mm F2.8 ED.
For anyone’s work, the D300s and the 7D will both suffice.
Winner: Tie. It really depends on your needs too.

High ISOs

The Nikon D300s uses a 12MP APS-C sensor with a 1.5x crop. Nikon’s formula is simple—low megapixels but excellent High ISO images with low noise. It has been working for them for a couple of years now.
For the Canonites, the 7D uses an 18MP APS-C sensor with a 1.6x crop. Because of this, the Canon sensor is just slightly smaller than the Nikon’s. To counter the problems that could arise from High ISOs, the camera has Dual DIGIC IV processors. Otherwise, the images would probably look much like the Canon T2i’s. You can see what those look like here. Granted though, the images have been edited.
Don’t expect to not do noise reduction to the files that come out of either camera at high ISOs. But in this case, the Nikon D300s does do slightly better because of the lower megapixel count. This isn’t by a very large margin either.
Winner: Nikon D300s

LCD Screen

Both cameras have large LCD screens designed to be utilized to check for minor details. Because of this, they are both of high pixel count.
The Nikon D300s comes with the equivalent of what could be called a condom for an LCD screen. There is a cover that goes on top of it to prevent it from becoming fogged up from the photographer’s breath. This is nice in practice. What’s even nice is the fact that it doesn’t seem to obscure the view of the LCD at all either.
For what it’s worth though, the 7D’s is more useful. The reason for this is the way that it was designed. The 7D’s screen can be used by videographers that need to zoom in very closely to their subjects to ensure that their focusing is spot on to the nearest pixel. This assures quality and optimum sharpness to the user.
While the D300s can do this, it isn’t as useful as the 7D’s. The extra nail in the coffin comes from the color schemes used in the menus—which can really aid visually impaired photographers.
Winner: 7D

Metering

This is an issue that has been debated back and forth for many cameras. I’m going to put this one to rest—they’re both good enough for whatever any photographer needs. They are accurate and reliable and will not let a photographer down after lots of use in estimating the exposure needed for the shot that the photographer wants and not necessarily what the camera meter tells you is balanced, overexposed or underexposed.
Winner: Tie

RAW Image File Versatility

Here’s where I may be opening up a can of worms to readers. Try playing with the Nikon D300s’ and the Canon 7D’s files in Lightroom. Manipulate the colors to get an accurate reading. To throw more heat into the fire, shoot a concert with multi-colored lights in auto white balance.
For what it’s worth, the lifelike color will be better achieved by the D300s. I say better achieved because it still isn’t perfect. Put the files into post-processing though and you’ll see that the 7D will allow you more versatility in the exact look you may be going for. Desaturate all you want with the 7D’s files to get the exact level of color that you want. Sure the files may be off in this shooting situation, but you’ll be able to get them to be accurate enough for publishing.
Winner: 7D

Conclusion

Get the camera that suits your system. If you’re a Nikon user, get the D300s. If you’re a Canon user, the 7D is a great option. If you’re thinking of switching systems, remember that both cameras are still different beasts and can do different things. Make sure you know what your needs are before you purchase either one.

Review: Pentax K-30




We’ve shown initial sample photos from the Pentax K-30 (K30) and we’ve also run the darned thing under a faucet. After about a month of use, constant communication with the company, and even calling in other products, the K30 is perhaps the most impressive entry level DSLR camera that we’ve seen. I’m not just saying that from my point of view, but this also applies to at least half the staff (who reside here in NYC) who have tried it out and also tried out other competing DSLR cameras.
In a nutshell: the Pentax K30 wins our Editor’s Choice, but it comes with its quirks.

Ergonomics

The Pentax K30 is an extremely beefy DSLR for the price point and for the audience it is targeted towards. Most prominently, I’d emphasize just how comfortable the grip on the camera is. On said grip, what you’ll also notice is an infrared trigger light there as well. That is also where the on/off switch, shutter release button and the program exposure and exposure compensation button are located.
Around here is also the first of two control dials as well. Yes, Pentax put two dials for exposure on the K30, and it is a godsend in terms of ergonomic comfort and control.
On top of the camera is the mode dial: which also includes some Pentax custom modes that are assigned to specific dials as it is. Plus there is a textured thumb grip area that adds to the overall comfort of the camera.
The back of the camera is characterized by quite a brilliant LCD screen and the viewfinder above that. To the right of all this are the main controls. To the top left is the Live View/Delete button. Honestly, I wish this were on the right side as well. It would just make more sense in real life use.

Autofocus

I need to get this part out of the way, and unfortunately it is probably the camera’s biggest pitfall. The autofocus on the Pentax K30 isn’t exactly the greatest and in fact it was sometimes extremely frustrating. While on a shoot with a model, I didn’t always have time to pixel-peep my images to ensure that I had absolute focus. Plus, the LCD screen was just so sharp that I honestly thought that I did. But utilizing the outer focusing points caused some major problems.
First off, when you’re trying to take portraits, you have a couple of choices:
- Set the camera to automatically choose from 11 autofocus points (a fairly viable option)
- Set the camera to automatically choose from 5 (not so much that viable when it comes to portraiture)
- Manually select one of 5 points (therefore disabling the ability to use all of the other settings assigned to the hot keys such as wireless flash control fine tuning, ISO control, etc.)
- Manually select one of 11 focusing points (the most viable option but with the drawbacks of the previous fact.)
In a case like the photo to the left, I needed to use one of the outer focusing points and hitting Jamie’s eye wasn’t exactly the simplest thing to do. My original vision was to have the lens wide open and only have a bit of fill flash coming in using the AF-540Z in a Photogenic SB2432 with a Chimera Speedlite Speedring. Instead, I needed to stop down and blast Jamie with light.
So why do I need to use the outer focusing points to begin with? Why couldn’t I focus and recompose? Because then I’d throw off the plane of focus. It would be nice if Pentax utilized something like Hasslebald’s TruFocus system that was designed for those types of photographers.
When the focusing was spot on though, it nailed some extremely nice images and the potential of the K30′s sensor combined with the very good 16-50mm f2.8 DA * was fully realized.
Something else that must be praised was the fact that the image stabilization system built into the sensor seemed to rival Olympus’s. And that’s a bold statement.
Here are some other images from that shoot:

See how the focus is right behind Jamie? I was aiming for her eye.
Something else that also must be stated is that Pentax’s P-TTL system seemed to work best when the flash was in the hot shoe and not in a modifier. These images in the bedroom were all taken by bouncing the flash off of the wall.

Ease of Use

Sans the autofocusing issues that I encountered, the Pentax K30 was extremely simple and straightforward to use, for stills that is. When it came to video, I encountered a problem that hopefully Pentax will fix with a future firmware update (from the time of publishing this piece). In video mode, a true videographer would want to shoot in manual video mode. When doing this, only the shutter speed and ISO can be adjusted: not the aperture. That’s a big problem; and instead I would probably opt for third party glass in this case.
The biggest joy though probably came from the fact that I was able to go out and shoot in the absolute pouring rain with no issues at all. The camera was drenched but survived it all like a champ.
Indeed, Dumbo in Brooklyn became so flooded that boats were ready just in case of anything since it is right by the water.

Image Quality

The overall image quality from the camera was exceptional, though at times I wished that the colors out of the camera were a bit more saturated than they were and that the green color depth could have been a tad bit deeper. Here are some images not only showing off the image quality, but also the versatility of the files when put to the test in Adobe Lightroom 4.
For more, you can check out our initial sample images.

High ISOs

Overall, I did see a little bit of smudging of details at the higher ISOs. However, the noise levels were nearly negligible and it required only moving the slider around one or two places in Lightroom 4 to correct it.
What must be said though is the fact that the camera white balances and captures some really, really wonderful colors at night and at higher ISO settings. Pentax did an excellent job with this.

Metering

Pentax is spot on with the metering. During my excursion with the rest of the NYC Press, I did formal Sunny 16 tests and the camera’s meter worked perfectly with the logic.
With that said, I would not be afraid to use it with manual flashes and studio strobes like anything from Profotoor Elinchrom.

Conclusions

For the audience that this camera is targeted towards, Pentax has given them quite a bit of power. Due to the ergonomics and including two dials, the user can grow significantly with this camera. When you reach a certain point, you often don’t want to have to press the exposure button in order to switch the aperture and shutter speed. To boot, this camera has a great sensor, is weather sealed, and is still fairly light though beefy feeling at the same time.
My only problem was the autofocus system, which I truthfully consider to be a tad bit worse than the Canon 5D Mk II’s. I know that Pentax fans will try to rip us apart for that, but our tests showed otherwise.
If you can get over the autofocus system, I highly encourage you to spring for the Pentax K-30 and enjoy their line of limited prime lenses and their constant aperture zooms.
