I love selectable aspect ratios in-camera -- it was a great feature on the Pentax K-01. I was happy to see Pentax take the idea from the Micro 4/3 world where it is standard. This is a feature I hope to see in Pentax cameras again. Obviously this is easier to do in a mirrorless camera, but DSLRs could offer framelines in the viewfinder that adjust.

When/if Pentax adds selectable aspect ratios back to the their cameras, I have one more request: please include 4:5 as an aspect ratio. In North America, common print sizes are based on this ratio, dating back to film photography standards: prints were 4x5 (standard snapshot), 8x10 (standard "portrait" or size for the home) and 16x20 (common enlargement size for home display.)

It seems weird that the whole 4/3 and Micro 4/3 format is based on the dead aspect ratio of televisions and what the kids now call "square monitors." 4:5 makes much more sense as a photographic aspect ratio. After all, the 6x7 film format was marketed as the "ideal" film format for exactly this reason!

K-1 offers 1:1 aspect ration crop in the OVF and output files.
Additional aspect ratios could be implemented on the K-1 or follow on cameras. The LCD mask or other method of indicating what is being captured seem pretty important to making this usable. Alternately it could be implemented for LiveView only or with a LiveView preview. With a pure OVF without overlay it can be clumsy. Special focusing screens with mask marks were used in Film Days for this. My F2 used the T (TV) screen which was marked with 4:3 ratio as well as some additional aids. I didn't use it for that purpose but I liked that style screen for other reasons.

Thanks UncleVanya, one more reason to buy a K-1.

I'm glad the K-1 has received an LCD mask -- it's an effective technique that Nikon has used since the F80. I really appreciated the customizable frame lines.

Perhaps Pentax could give us the option of 4:5 lines on the K-1? Firmware update? Please Pentax :-)
