The is a very small review of the 28-105 lens here. (Click on the quote)

I'm not a particularly big fan of kit zooms, but this one was sharp and felt better-built than I'm used to. It goes without saying that the all-metal primes felt great, even if I had to stop them down a bit for optimal performance.


And a pic


It looks biggish for a 5.6 lens.

Couldn't really find equivalents the Nikon is APS-C and the Canon starts at 24 but both 3.5-5.6 and end at 105. It is quite a bit smaller than the Canon and a bit bigger than the nikon, but that only covers aps-c.

It's the same diameter as the DA18-135, just one centimetre longer and a fraction heavier. That makes it smaller and quite a bit lighter than the DA16-85. I have the DA18-135 now and when I tried the K-1, the DFA 28-105 felt so familiar that I completely forgot I was trying a new lens too.

I must be totally over estimating how big the K-1 is.

Apparently they don't have the 18-135 in camerasize... otherwise I would have put the 18-105 on the K-1 and the 18-135 on the K-3ii...

Same 62mm filter diameter, besides quality and reasonable price, size IS actually an argument in itself to put DFA 28-105mm on K-1...

Possibly. Almost all the size increase of the K-1 over the K-3 is in the height, so from that angle, it basically looks the same size. The PF lens database has the lens dimensions and both the DA18-135 and the DFA28-105 are shown as 73cm in diameter, with the DFA being 1cm longer at 86cm.

They are very close - I had a hard time telling which was which in the "family photo" (right side, behind the DA 40 XS, 3rd & 4th from front - the 28-105 is the one with white text around the front barrel edge)

Exactly. I downloaded the "lenses family portrait" and tried to identify all lenses and had hard times telling which one is the new kit zoom. But I identified it like this:

Nice work!

But seeing numbers (eg 19) duplicated for different lenses, and the uncertain logic of the lens colour codes, confuses me. I think it would be clearer to just to have one number per lens, and simply colour code the number according to if a lens is FF compatible or APS-C only.

You are right, it is a bit confusing. I wanted to differentiate zooms and primes. Zooms are marked green, primes are yellow, but I somewhow forgot to write descriptions in matching colours. I will redo it when I have some time.

28-105mm very good samples

About the quality of the 28-105 lens, from the samples in this link Sample Image? PENTAX K-1 | RICOH IMAGING I was amazed! The photos looks excellent. Studio photography (at f8 !) and landscape (at f4.5 !!) is very nice across the frame.
On the other hand, the 24-70 at f8, at the corners, is reminds me a little of my 16-45, with some issues.
If the samples of 28-105, from the users and testers, will be as good as those in the link above, then, the choice will be very difficult...
Comparing the two lenses for my use: When I am shooting landscapes I never use f2.8 and the extra 4mm is not that a difference. I very often use my fish-eye and I'm thinking of buying a fast wide angle prime, mostly for indoors.
For indoor and considering the high iso performance of k-1, if the 28-105 behavior at f3.5 is comparable with the 24-70 at f2.8, then.... ???

Additionally the 15-30 f2.8 seems to be nice, but why don't take a good wide angle prime? The zoom range is not that big.

Agreed, these pictures do look good. Looks like a nice outdoor lens.

OMG the details in the woven fabric and the green-red hortensia flowers in the pixel shift version of the studio shot!!

The zoom range is ample - compare a shot taken at 15 mm with a shot of the same scene at 30 mm. For landscape photography that can make all the difference.
