Win a Pentax Limited Lens: Raffle Now Live!

Adam · 11-03-2013, 06:30 PM

Tell me which photo is from the Pentax K-3, and which is form the K-5 IIs. Both shot from the same tripod with the same lens (DA 35mm Limited) at the same aperture with the same white balance. Developed from a RAW file at default settings in ACR. The K-3 file was scaled to match the K-5's resolution.

Have fun!

File one
File two

My vote goes to Pentax K-5 from 2010

**BobL** · 11-03-2013, 06:49 PM

I was hoping that the Chromatic aberration would have improved but both seem to be about the same.....or is that from the lens?

yygomez · 11-03-2013, 06:50 PM

File one = K3

sethman2010 · 11-03-2013, 06:51 PM

I'm guessing B.jpg or file two is from the K-3.

dane.dawg · 11-03-2013, 06:56 PM

I hope file one is the k-3

Racmanaz · 11-03-2013, 06:58 PM

File one is the K-3

maybe both are K-3?

Big Dave · 11-03-2013, 07:00 PM

File one has the best dynamic range. It mist be the K3.

jaad75 · 11-03-2013, 07:00 PM

That was easy one.

NickLarsson · 11-03-2013, 07:01 PM

I would say file two is the K-3 because of the colder AWB.

That is a lens issue.

I seem to see moire on the background fence in both images, so I'm confused...still feel image 1 has slightly higher resolution and voted that one is K3.

*edit* Nevermind, now I see the comparison is between K-3 and K-5IIs (I thought it was K-5), so if K-3 has AA disabled I guess both would show similar moire.

The K-3 is not going to have better DR than the K-5IIs.

There is one thing to look at which separates downscaled pictures from native resolution ones, and it is obvious in this case.

BigMike · 11-03-2013, 07:04 PM

Two = K3

JinDesu · 11-03-2013, 07:04 PM

File 1 is clearly more detailed.
