Ctein addressed a lot of these issues early last year after the D800 was announced. Anxiety about 36 megapixels bunched up a lot of shorts. Myth no. 4 is particularly relevant here.

Oh I don't doubt the resolving capabilities. But it was my understanding, and I think I'm wrong, that KAF2 allowed metering without stopping down.

Well I guess it's a "crippled" KAF2, the most recent iteration, for digital bodies and DA lenses.

I shot with a Sony a7r for a while using the m versions of 28mm f3.5, 50mm f1.7 and a takamur 135mm f2.5.

That's a rediculous 36mp and the lenses did a sterling job!

I'm waiting on my k3ii to be delivered tomorrow and I'll be shocked, no, amazed if the lenses come up short.

Way to resurrect an ancient debate n00b.

Oh, and welcome to the forum. Glad you chose to join in the discussions.

One of Pentax's strength has been the ability to use a wide range of excellent lenses from the film era, but I just can't help wondering whether those days might be over with the arrival of the K3 and the 24Mp sensor. As sensor technology advances, the demand for better optical quality becomes more pressing and it might be that the older M and K lenses may not cut it with the arrival of this new camera. Ray

I don't think the K-3 sensor can yet match the resolution of some of the 35mm films. So for the time being, a decent M or K mount lens will still be decent on the K-3. And of course, cheap (different from inexpensive) lens from the film days will still seem cheap on the K-3.

With that in mind, I'd like to point out a bit of history. Today people pixel peep to see how sharp a lens renders an image. When I started photography, lenses that were smoothly soft sold for a premium. Photography magazines had multiple articles on how to artificially soften lenses that were too sharp for glamorous portraits.
