No clue on what decade, my wides look mint, but if they're both 37XXX, can I assume they're Tokina?

Thanks. I'll check the long ones when I get home--and they're OLD.

Seems weird that as long as Vivitar was around, they only had one 28 2.8 in manual focus? Because that's all Wikipedia lists.
There are many different Vivitar 28mm lenses. Some have become quite coveted! A quick search should turn up the Vivitar 28mm thread.

I had a chance to take some photos with my copy of this lens. My lens has a KA mount which is a nice addition. I have the Sigma SuperWide II 24mm f2.8 and the Kiron 24mm f2.0, both of which are sharper. The Sigma is probably the best overall performer. Someday I'll do a more formal comparison of these three.

All of these examples are the Vivitar at f2.0. First, a photo I've posted before of Christmas lights. The lights are not globes.



Second, some flowers from today.





The flowers were at or close to the minimum focus distance, which enhances the effect. It's similar to the Cosina 55mm f1.2, except with the Cosina it's easier to fill the frame with a flower without crazy postures.

After a short time of owning this lens I found the colors to be cooler in temperature in most situations and sharp from only f/2.8. I realize that wide open lenses aren't as sharp as stopped down but f/2 is very soft and f/2.4 is just passable. For my needs I didn't see the point in keeping it. I have since sold this lens, actually got $30 more from it than what I paid.

I think I like the effect. The Sigma does a pretty good job for sharpness, so I can choose whether I want sharp or not. I considered selling it; just with its specs it would sell for a good profit. I love the Christmas light thing, though.

Yep, these lenses need to be stopped down one. But then they are great. And still one stop faster than my DA12-24mm.

actually it's 2 stops faster. although I'm not complaining that the DA12-24 is shot at f4 and smaller.

if I want something shot at f2 or faster, that would be in the 28mm range.

Stop down an f/2 once and it is one stop faster than the f/4 zoom, which is totally usable wide open. Unfortunately I have not found anything 24-28mm that is crisp and usable at f/2.

maybe the K28/2? but that lens is hard to find. I could had gotten myself one if only the seller didnt retract. bummer.

I just got one 24/f2 made by Kiron and I can confirm that at f2 it's really soft. Must be stopped down to f2.8 to see reasonable sharpness. I can't complain much for what I paid though, roughly under $50 at a local store

Nice one. I think of it as one stop faster than the zoom but more compact.
