It don't have compet here !

- don't care about sensor shift, because with a 24MP APS-C it would be better working with mono or tripod!

I am not sure I understand your rationale here.  The sensor shift if it works properly is a superb feature to have.  The amount of details you get by removing the AA filter makes quite a bit of a difference, specially when you get higher pixel count.

- no question about AA filter, because the A77 have 3000 lp/mm what outresolve any lens on the today DSLR market...

Still, you will see the difference with or without AA filter.  What's more interesting is that Pentax seems to have found a solution to the AA filter problem, and can possibly remove Moire for situations that need to do so.  I think this is something to acknowledge from Pentax.  I consider this as a significant move, specially that no other companies have thought of it.

- With 10 fps, the A77 outperform the AF system of Pentax ( of course)

10 fps vs 8.3 fps but buffer is almost 40-45% larger for the Pentax.  For an APS-C DSLR camera, that's pretty darn good.

- Since you use the SLT most of the time for stills, what about the LCD (we don't need this one imho)

- 60i for vidéo applications, is not what is required for a today V-DSLR/SLT cam.

- dual card slot? Since you can see your shot on screen, and it showing well, it's just that you have on your memory card!

I am not sure I understand.

What is lacking about the Sony Flagship? Maybe you know already?

I don't think it is a question of lacking, but a matter of preference.  If someone is seeking for an OVF, the Pentax might be a nice option.

I' m afraid the Pentax don't have what is necessary fot this class of sensor:

- no AF micro adjustment?

I believe the K5 or K5ii(s) has it.

- no area-specific noise reduction (NR) and sharpness enhancement algorithms? What can vary the amount of NR/SH depending on the content (Area specific noise reduction and sharpness enhancement!) is supposed to analyze image content and vary the amount of NR/SH depending on the content. Basically more NR in smooth areas (like a sky) and less in areas with lots of detail, so not to smudge legitimate detail, truly important feature with 24 MP, because the sensor outresolve lenses

Shoot raw, that's done in post-processing when one has full control over the phot.


- no standard battery pack?

- don't provide a clean HDMI signal?

- no real time logic of embedded thermocolorimeter? Do your remember the one of Minolta? This point is the most important problem of Pentax here. Mostly is in-camera over saturated comparing to the standard of Graphic Industry imho.

Of course the lacking of all what you don't have with an OVF comparing to SLT (but it's personnal).

And if you really want's to compare with FF -SLT features:


The remaining is nothing relevant to what Pentax is proposing with their K3.   The K3 seems to be on the paper a very powerful took for still photography.  Let's wait for the reviews.

Hello Sony SLR community,

Alright, I am not sure about you, but I found the new Pentax K3 to be very appealing. At least on the paper, it is the best APS-C camera.

It has (almost) everything to dream of, good MP count, built-in IS sensor (newer generation), no AA filter, but with revolutionary technology mimicking the AA filter while shooting subjects prone to Moire (e.g., clothing), new AF system (with 25 crossed-type points), superb ergonomics, focus peaking, 8.3 fps with good buffer (23 images in raw, which is not too shabby), etc.

Not sure what to think since I am a Sony shooter (a850/a900), but I would certainly show some interest in getting one, specially with the 18-35 mm f/1.8 from Sigma, it should be a killer combo.

Anyway, this Sigma lens is also available for Sony A-mount:


I checked the full resolution samples posted from the Pentax website, and samples #3 and #4 are quite impressive, plenty of details to play with. I think it is on par with what I see with my Sony a900.

Personally, I think this was the route Sony should have kept pursuing rather than choosing the SLT route, but this should possibly be concerned with another debate.

Anyway, I would be interested in knowing what the Sony SLR community has to say about this upcoming release.

Thanks for your comments/insights.
