I've got a Pentax SMC-A 35-70 F4 with good macro capability for sale on ebay. Was kit lens with my wife's Program A a long time ago.

It seems a weird focal length range for the 21st century...

-Eric
Vintage... Anyway...28-105/3.5-5.6 has better resolution than 24-70/2.8 at almost all focal lengths. 24-70 is just a bit better at 24 mm only.

35-80/4 macro is interesting

A real macro zoom would be a novelty, but 35-80 would be a somewhat weird focal range, wouldn't it?

I'm still flabbergasted by the complexity of this lens given it's modest aperture and zoom range.

Maybe Ricoh is having us on and are now laughing at the comments.

35-80mm is a nice walk around lens for street and tourist type shooting. I think it would be great for shooting outdoor groups. Check out my 35-80mm 2.8-3.8 Adaptall of FF...one of my favorite lenses.

Sure. But maybe not an oversized monster with umpteen elements like this looks like.

First I heard of this, so I headed over to ephotozine and yes, that lens looks surprisingly good. And weather sealed to boot and much, much lighter...

You've got to remember that the 35-80 lenses of yore were generally not constant-aperture affairs; the were f/3.5 or 4 at the wide end down to 4.5 or 5.6 at the narrow. Keeping that constant f/4 is going to bump your size up, though I agree there's probably an element of "let's see how much glass we can stuff in to make sure every little aberration is corrected always" in the design thinking.

Then it would appear that this...

No kidding, why 35? The 28-70 f/4 AL was decent, give that one a refresh with some better QC than the original.
The FA 28-70 f4 is very decent indeed on aps-c (lens separation issue aside) and 28 is a much better fit than 35 for aps-c.
FA 24-90 f3.5-4.5 was a decent lens too. Why not re-issue (and refresh) one of those?

I guess too close from DFA24-70 rangewise...

I suspect a new-build consumer-level variable-aperture 24-90 might take sales away from the 24-70, for those users who were prepared to live with the slightly slower and variable aperture (e.g. always using it in bright sunlight), and also the 28-105, for those who were prepared to lose the extra 15mm at the long end.

If the patent said 24-105 I would believe it, the dimensions and number of elements would make sense. Nikon Canon and Sigma Have Similar offers. All struggle at being excellent though.

What benefits would the K-1 with a bag of F4 zooms have (if any) over a K-3 II with a bag of F2.8 zooms?
From what I've seen, a K-1 wide open at 4 and 6400 ISO, would have less noise than a K-3II at 2.8 and 1600 ISO, the same DoF, half the weight. of a comparable 2.8 lens, Having a 60-2504 instead of a 70-200 2,8, I have to say, this would be a lens I might be interested in if the cost differential, is like that of the 60-250 and the 70-200, and the quality is up there with the 60-250,

I have an FA 35-80 I use occasionally on APS-c. It would be a lot more useful on FF,
