it takes personal vigilance to find a good deal. this does not only apply to one particular lens but others as well, you should know that by now.

This is true. I think, though, that this sort of vigilance would lead a rational person to the DA L 35, used, for about 160 dollars.

Just saying .

Even *IF* there was a $300 F 28mm, thats still over $100 difference! To me at least, that isn't some small amount. In addition, I've yet to even see a $300 F 28mm. I got mine for ~$250, Dgaies fairly recently sold one for $260 in excellent condition, etc.

Generally speaking, on the used market, the FA35 sells for between $375-425 and the F28 sells for about $225-275, in excellent condition.

For reference, the F28 I sold a few months back for $260 was in like new condition which is why I asked closer to the upper end of that range (link). I also sold a copy about a year ago for $165 (link), but that copy wasn't in nearly as good condition. And there was a third copy in there I sold for $235 (link) which is was in excellent condition, although not as good as the one for $260.

I think it has a lot to do with him owning the 31...

I much prefer the FL of 28mm over 35mm, for "normal" work.

Exactly! I got my F 28 for about 1/5 the going price of the FA 31.

On further thought, and looking at the price of an F28, I think I would go for the Tamron 28-75 before the 28mm 2.8 prime. For an extra 100, I would have access to many other useful focal lengths!

While that Tammy is a a good lens, it is gi-normous in size compared to the F 28/2.8. In fact, it is somewhat smaller than th

jsherman's reason for not keeping the 28mm is the same reason why I didn't like the F28 in the first place. as I had mention on my earlier posts, I just didn't see anything special about it, especially having a fast 35mm. if sharpness alone is the criterion that I'm after, I already have that on the 35mm, not to mention that it is fast. although I would prefer a 28mm focal length, I just didn't see anything else that would make the 28/2.8 more desirable than a 35/2. so obviously, having a 28/2 would make more sense and I would likely invest on, providing that the blur is consistently smooth in most, if not all occasions. makes it more ideal for other uses such as portraits and candid.

You skirted my response to your dismissal of lens formulae having an effect on lens performance and the gist of my post was that the FA and F 28 are completely different animals due to different optical formulae.

The F has 7 elements arranged in 7 groups.



The FA has 5 elements arranged in 5 groups plus has an aspherical element in the design.



Images compliments of Dimitrov. As I pointed out earlier, 8 or 9 out of 10 people who have used both the F and FA prefer the F version of the 28. This thread is about the possibility of a 28mm lens, not about the FA 35/2 and the DA 35/2.4.

Edit: and just for kicks, here is the current Zeiss Distagon T* ZK 28mm/2

Yes, that is what is keeping me from committing to it .

I paid $300 shipped for a mint copy maybe im a fool

Got the lens I wanted though

dgaies That last one you sold for $260, was gone by the time I saw the listing, which I might add sold very quickly...

I love my M28 2.8, just wish it was auto and had more than 5 aperture blades. If Pentax were to make a D/FA28mm f2.4 (for the up-coming FF of course) with rounded blades, I'd snap it up.

That's true, it did sell pretty quickly at $260, which suggests that perhaps it might have been slighty underpriced. That said, I try to price things fairly and thought $260 was about right at the time. FWIW, $300 for a mint copy isn't terrible either, and as you said, you got the lens you wanted and that's really the important part at the end of the day

Im not talking about a new 28mm anywhere in my posts, just talking about the F 28mm.

you talk about preference on the old existing AF 28mm lenses. but it doesn't change the fact that a faster one would be more ideal for a new 28mm rather than put the old F or FA 28mm lenses back into production. let's just see how the demand for a 28/f2.8 turns out. but anyways, we don't have to wait for that. we can already see it on how people are badly into those lenses, don't they?

I didn't say jack about putting the F or FA back into production.



I originally suggested a DA ltd or perhaps DA* at perhaps f2.4 back in post # 12 https://www.pentaxforums.com/forums/1519507-post12.html. As far as the re-sale of the used F and FA 28 lenses, they go up in the marketplace about as frequently as the FA 31 does, oh wait, that is another old p.o.s. film af lens.

of course. who knows, it might start raining with FA31s tomorrow.
