Sorry for the late comeback, I got really busy with
my upcoming trip.
I shot the scene bracketing shots using DA70 at f/8 and ISO 100 and ISO 80 respectevely (I did use the same shutter speed for both bodies as I only use half stops shutter speeds)
First on a tripod at lowest ISO and then handheld at lowest ISO and ISO 1600.
Disclaimer: The scene is crappy and all but it has shadows, highlights, blown areas, specular highlights, some foliage, small details, etc...
Focus was achieved through liveview on the blackboard that reads "Cafe con leche + 5 medialunas" on the lower left of the center (behind the other black board). The focus plane is arround 30 meters away so DoF should be good at f/8 without compromising quality due to diffraction too much.
Of course:
- 2sec timer (so MLU on and SR off automatically, thanks Pentax)
- Tripod
- DNG RAW
- 6 bracketed shots from 1/30 to 1/180 in half stops so there´s over and under exposure to play with.
For the handheld attemp, focus was achieved putting the lowest right corner AF point on the same blackboard than before, using AF single mode. SR was engaged and everything else remains the same.
My personal conclusion:
There`s no significant advantage in resolution or resolving power between the two. That said, there´s also no significant difference in noise or dynamic range either. That`s a great thing, since the K-3 does everything the K-5 does and more.
Also, the performance and handling of the K-3 is much better. Haptic feedback is amazing. Liveview is a thing of it´s own.
Here´s the
