Full Frame (K1) - it's the FA 20-35 f4 by a mile, great travel/landscape lens - lightweight pretty good IQ, ideal wide angle range covered (for me)

APS-C (K5iis) - it's the DA*55 f1.4 - superb portrait lens, oozes quality and allows you to play with the ultra-thin DOF if you wish

For APS-c no doubt it's the 18-135
For FF it's the 28-105.

Those are what's on the camera most. As for what I have the most shutter actuations with, I can use the Tamron 300 2.8 or DA*200 or DA*60-250 with TCs and take 500 wildlife or bird images in a half hour, so in terms of number of shutter actuations, that would be a different answer.

Looking 2014 to 2016 mostly APS-c
of 12,5000 keepers

DA 10-117 - 144
DA 21 -300
DA 18-135 2,300 (roughly 20%)
DA* 200 - 2,000
DA* 60-250- 2,500
Tamron 90 1,700

Very few other lenses are over 500 keepers.

I guess for APS-c keepers, that makes the 60-250 the winner even thought the 18-135 is my "hunting for pictures" lens and is usually on the camera when I head out


Analysis of K-1 lenses is tough. The 28-105 is not acknowledges by Aperture. It's recorded as "Unknown Lens" . Anything taken with the 1.7 TC is recorded as "A Series Lens" and there are three lenses I use with the 1.7 so identifying which is which is problematic. But I'm frequently using the 60-250 as a walk around lens so it's between it and the 28-105.

35mm format = FA43/1.9
6x7 format = 67 75/2.8 AL (equivalent to the 38mm focal length on FF)

Both are perfect one lens options in each format, with good handling and superb optics..

pentax 67 : 105mm f/2.4
apsc: da 18-135mm, weathersealed all-rounder at a very reasonable pricepoint.
sony a7ii : 35mm f/1.4, heavy but great for environmental portraits when travelling.

There once was the concept of a "normal" lens. The focal length was determine by measuring the diagonal across the frame.

From the good old days when film ruled the imaging world.

For 35mm it was about 50mm
For medium format it varied from 75-105mm. 75mm for 645 and 6x6. 105 for 6x9.
For 4x5 it was roughly 155mm.

in a prefect world these photo would all offer the same area of coverage. n the film world this meant that it may be possible to have a lower quality lens on a medium format camera out perform a higher quality lens on a 35mm camera. That is one reason why lenses for 35mm cameras are so expensive. The smaller the format the higher the lens quality you need to insure good image quality.

It would be D-FA 35 and D-FA85, but until they are available it is the D-FA24-70 on K1.

what is your most productive lens ?
By "productive" I assume is meant shutter actuations. In that sense, taking in the entire period I've shot APS-C digital, my most "productive" lens would be the DA* 300, even though I don't use it all that often, have used it even less in recent years, and throw out most of the images shot with it. Despite all such caveats, I have more images in my Lightroom library from that lens than any other. When I do use it, I take an absolute ton of shots with it.

On FF (i.e., 35mm film) my most used lens by far was the Pentax M 28 f2.8.

On m43, the Oly 14-54 f2.8-3.5.

"productive" could be the way you interpreted it, or as the lens that gave the most keepers. I deliberately left it ambiguous ...
