Canon 7D vs. Pentax k-5
Dec 1, 2011

Hi everyone!
I'm having hard times, cause I'm moving on from Sony.

I won a Pentax k-5 body from a photo competition, but can't decide wether I should start to work with that or sell my sony and the pentax, and buy a canon 7d...

I've read multiple articles about these cameras, but it just makes the decision harder..

I've read that the k-5 has much better image quality ( http://snapsort.com/compare/Canon_EOS_7D-vs-Pentax_K-5 ), but I don't know how much I believe that comparison.

thank you

Forget snapsort - it's rubbish.

They are both great cameras.

Can you tell us what type of photography you intend to do?

oh..

well I'm kind of dude who shoots nature and landscapes, but I'd like to try also portraits and sports. I've been shooting with sony alpha 300, but the bad ISO performance and the lack of good lenses makes me want to change camp.

There's no better all-round APS-C camera available today than the 7D - it does everything well.

Rarely I have seen a more incompetent and inaccurate comparison between cameras.

The K5 has a wider dynamic range and slightly better high ISO perfomance from the Sony sensor, but I'd still prefer the 7D for the range of lenses.

Could you please provide us with examples of inaccuracy in the Snapsort comparison between the 7D and the D7000? If you can that would be helpful, if you can not, then please respond with a simple "No." My guess is that you will evade my question with some idiotic response like "Everyone knows the 7D is better," or some other great insight based on your opinion and not facts. Snapsort uses the same criteria to compare all cameras, so it will be interesting to see how this particular comparison is flawed. And don't waste our time with the Image Quality score, that is based on the respected DXO Mark tests, unless you feel that they too are incompetent as well. We are looking forward to your reply.

The K5, and D7000 share the same sensor made by Sony, but the D7000 puts it to better use I believe. Anyway the Canon 7D is built more robustly than the Nikon D7000, which while built better than the D90, only uses metal as a cover, and back plate. Although this is true, unless you really need tank like construction you will be able to get better overall IQ with the D7000, compared to the other two cameras, as long as you make efforts to understand the camera. There for instance is an excellent series of three videos at testcams.com comparing the D7000, to the 7D. You'll find it in the April postings he made I think. Look for " Does the D7000 over expose" As a D7000 owner I can say it is capable of stunning results, but much like most complicated devises requires some work to understand it. Good luck

Smaller = better?
lighter = better?
unqualified more focus points = better?
weather sealing on the D7000 is inferior to the 7D weather sealing!
DR measurements are ludicrous in value - so whatever they measured it's not DR.
I could go on but that comparison is not worth any further in depth analysis!

DR measurements are a fact. Check DXOmark, or dpreview.

The "score" also includes ...

"Popularity" - based on how many fanboys vote for a particular camera - seems the D7000 has many more - LOL!

And strangely, "Lens availability", where the D7000 also scores more, even though the Canon offers way more options.

Honestly - snapsort is a bad joke. Laughable at best.

And the fact that we have to explain this to mforbes tells us a lot about him too

The values reported are a farce. DXO doesn't measure anything that has any bearing on real life photos. DPreview at least has some credibility and reproducability and can be checked in real life, there the difference between the 7D and K5 are basically equally capable with the 7D having a bit more RAW headroom while the K5 has a tad more shadow DR.

As I said don't get me started, the whole comparsion site is reporting pure garbage without any method documentation it deserves no credibility whatsoever!

The "fact", in fact, is that the Sony sensor enjoys a DR advantage at ISO100 and ISO200 - after that there is nothing much in it (around half a stop at best).

And the more relevant fact is that a DR advantage at the two lowest ISO setting does not equate to a better camera.

Believe what you will, but as a former 40D owner I can tell you that both my D300, and D7000 have noticeable better real world dynamic range.

Whatever they may have, it's not noticable. I have checked enough RAW images from all these cameras to refute that claim. They have differently set up JPEG engines and the D300 and D7000 clip their black value - which may yield a different look which you may perceive as better on a monitor which can't cope with the full dynamic range of the photo...

iLinkola,

First let me tell you that I am no fan boy of any particular system. I have shot Sony, owned a pair of a700's when I first started my business. If you want to know about good lens for Sony try this website http://www.dyxum.com they break down almost every lens that can be used on a Sony. The Minolta 28-135 f4 is a very good portrait lens, and any of the Minolta 80-200 2.8 APO or Sony 70-200 2.8 lenses will give you the speed for shooting sporting events. If you want to shoot sports, then you need a better Sony body than the A300. (a700, a55, a77)

If you are sold on changing systems. I currently use in my small company of three photographers a Nikon D700, Nikon D7000, a Canon 7d, and a Canon 40d.

Here is an important fact if you want to shoot sporting events and portraits, Canon has far more lenses to choose from than Pentax does. Pentax is a fine company with the best bad weather sealed equipment on the market. But can't give you the lens selection that Canon does.

It really comes down to how far do you want to take your shooting. I shoot mostly small college sporting events here in Massachusetts. I normally use my D700 with these lenses Nikkor 70-200 VRII, Nikkor 28-70 2.8, Nikkor 85 1.8. With the 7d I also use the Canon 70-200 2.8L. Only the Nikkor 85 1.8 is inexspensive glass, the others are far more exspensive $1,400.00 to $2,250.00.

So if you do decide to change systems, I recommend you take some time to decide your shooting interest. Then see which system has the equipment to match it. Also decide how much do you want to invest. Too many on here come down with a dreaded disease called Lensitis (the buying of too many lenses). It is known to drain many a bank account quickly, fill far too many credit cards to fast. Just beware. ; )

All the best and keep shooting ---

I've got a 7D and a Pentax system
In reply to iLinkola, Dec 1, 2011

It depends on what you want out of your camera system - neither one is better than the other, it depends on what YOU need.

The main advantages that the K5 has over the 7D can be summed up as follows:

  • newer, improved sensor. The DR at base ISO does look very appealing, there is more headroom for shadow pushing on the K-5 which allows you to pull more detail in RAW processing. This isn't to say the 7D can't do the same, but pushing shadows on the 7D isn't wise as we all know it can introduce some vertical banding. I find this is a moot point with my 7D as a) I use filters to balance dynamic range and b) I usually take a second exposure for shadows and using layering in Photoshop for superior image quality (landscapes only)

  • a selection of very compact primes. One of the main reasons the Pentax boys love Pentax is the compact nature of the K-7 and the K-5 along with their very small limiteds. If you need compact primes and a compact body (perhaps you travel a lot), then the K-5 is certainly good in this regards

  • weather sealed crop sensor lenses. Canon don't have any where as Pentax do, but these weather sealed lenses (the DA* range) have well documented SDM problems - you take your chances with them. I would like to see Canon make some headway into weather sealed EF-S lenses, I think they are lacking.

  • back catalogue of Pentax lenses. You can put any K mount lens onto a K-5 (with limitations on some), although you'd need to get these from the second hand market. My old man has old Pentax lenses and can put them onto a modern body, so he's happy staying with Pentax.

Those are probably the main points that the K-5 has over the 7D, however the 7D has the following positives:

  • the autofocus is just much better

  • USM lenses, those noisy Pentax screwdriven lenses just don't appeal to some

  • vastly better lens selection, particulary in the 300mm+ market. If you need over 300mm on the Pentax body, you need to go third party which blows the weather sealing advantage out of the water

  • solid and reliable lens rental market, I can get my hands on a Canon 400mm f/2.8 at short notice for a specialist job - you just don't get that on a Pentax system

  • more reliable flash metering and exposure (in my experience)

  • tethering

  • better third party lens options

  • much bigger Canon community. I find the Pentax community have a very nippy chip-on-shoulder attitude to other manufacturers

That's probably it at a high level - both cameras will take great photos, but Canon just does everything good, not just "compact primes" or "shadow pushing"

I shoot raw almost exclusively, but I'm not interested in arguing a point that's easy to check for anyone who's interested in facts. The difference is significant in my view, but we only have to please ourselves, and ultimately its not going to make or break a good photographer either way.
