Constant F4 tele-zoom options?

Canon has the 70-200 F4.0 IS USM that apperantly is king among men.

since the 60-260 is not here yet, is there anything from from the olden days that is of similar quality, or am i going to have to go sigma?

i have a Tokina 80-200 F4.5 constant thats the push-pull type manual focus, but the images are not what i would call breathtaking.

i dont do telephoto work but it would be nice to have one for those odd trips.

thats why i asked for F4

there are more than enough options for F2.8, but the lenses are monster

there are also more than enough options for variable aperture zooms.

on the other hand, maybe i should just buy the 50-300 and not worry about it? i mean, that thing is pretty small...

How about the A70-210/4? It's got a pretty good reputation around here.

And of course the 50-200 is even smaller, and cheaper. I'd personally go one of those two routes. I mean, f/4 is hardly earthshattering speed in the first place, and from there to f/5.6 just isn't that big a deal unless your needs are very demanding. And it sounds like yours are not.

There is just one thing you need to keep in mind, Marc: Those old Pentax zooms are sharp wide open, which most modern zooms aren't.

I have a few of Pentax's f/4 zoom lenses in different focal lengths and I generally shoot them wide open, because I can't really tell the difference in IQ. However, the DA 50-200mm I rarely shot wider than f/8 because it just didn't perform. I sold it and now have a Sigma 70-300mm APO...which I always try to shoot at f/8 too. So, I often find myself reaching for one of Pentax's trusty zooms when I need more light

I agree with Heather and Miserere. The A70-210 is an almost legendary lens. It's heavy.....heavy enough to bludgen someone to death. It's also very well built, very contrasty, and very sharp. One of my favorite lenses ever. I sold it trying to get "modern", but still haven't found anything that performs like that lens did.

I had the 70-210 f/4 and it was a nice lens. Unfortunately, my version had a bad case of fungus and I gave it away rather than have it cleaned. It still took decent pictures, though a little soft on contrast.

Another option would be the Vivitar Series 1 70-210. I had one of these as well (2.8-4), and it was a great lens. I sold it, but you can find them relatively cheap.

Either one are great options if you don't mind manual focus.

True enough, although I find the 50-200 "good enough" for most casual use. I have primes I use in more demanding circumstances. That is, if I am really concerned about needing more light or getting the ultimate in IQ, why bother with f/4 zooms when you can get f/2.8 primes?

Anyhow, I wasn't necessarily saying the modern zooms are the best in IQ. But for relatively occasional use, it might make sense to get a smaller/lighter lens with AF, as I'm guessing for most people that is going to encourage them to carry it around and put it on the camera more often. But we all have different biases and priorities.

I bought a Tamron adaptall 2 70-210mm constant f3.5 a few weeks ago off Ebay and it maybe a little bulky, it maybe manual focus but the images it gives are absolutely superb. It cost me the equivelent of $160 delivered to Spain but it was brand new in the box with all the bits and since I got it the thing hasn't been off my K10D.

I have a Tokina AF 70-210 f/4.5. A bit on the soft side @ 200mm wide open, but otherwise I'm very pleased with it (80 bucks lol).

It's all-metal, internal zoom. Tough as a 2-week old cookie, minus the crumble.
