Considering that the OP already has the 28-75, it would be worth considering the Tamron 10-24, since it would avoid the painful gap from 20 to 28.
See, the thing is that for what I am used to, a gap between 20 and 28 is not that painful really. I have the 28- 75 not as a show lens but a 'family' style lens. Something that my wife can use (strong AF, good range, etc...) without any issues as we are walking around. I normally carry the 50, 35, and 28 at shows. Lately, the 35 has been my go to. I am really, really impressed with it, especially at 2.4. I spend a lot of time around there to a couple stops down.
Originally posted by lesmore49 I do a lot of vintage car shows. As you say it's tight between cars.
I use my Pentax 12-24 mostly...it's a wonderful lens. Almost like 3D sometimes. I like the zoom...I can stand there , not move...just flick in between 12-24 and all stops between to get the look I want.
I also use my Pentax 10-17...but at 17mm and I shift around to get the right angle. If I get it right and by now...I've got the knack...the photo's really have added punch with this Pentax FE.
I wonder what the difference in wide open performance is between the 10-20 and the 12-24? I very rarely go around f/8 due to the tightness. Being able to bring focus on one thing and have everything else 'fade' into the bokeh is what I like to see. Greenwich Concours in a few weeks might be a little different though. I normally walk around with my 35 on the camera. If I cannot get what I want with it, then I swap to something else. Lower 20 range might be what I am looking for. I just cannot justify the cost of a 15mm for how little it will get use really. I know that the 15mm is sharper at 15 than the 10- 20 but the 10-20 will have the advantage in not needing the 'zoom with your feet' thing.
How fishy is the 10-17? Fishy at 10 and not so much at 17? Any examples? It is an appealing idea of a lens, depending upon how much it is.
