Sigma 50-150mm OS f/2.8???

Anyone got any information on this lens yet? I know it was introduced back in February and there still doesn't seem to be a release date on it yet. I'm guessing it is partly due to the earthquake aftermath that those in Japan are dealing with. I e-mailed Sigma about a week and a half ago, but haven't heard anything yet.
Any other crop shooters out there excited about this lens' potential??

Bump

It was discussed a bit on the Lenses forum when it was announced. I must admit the size/weight seems excessive and rather puts me off. The old non-OS version was virtually half the weight of, and much smaller than, the Sigma 70-200 f/2.8 - the new 50-150/2.8 OS is about the same size as the 70-200.

Exactly, that killed my interest right there. I'd like having the 50-70mm range but I don't care nearly enough to choose this over a 70-200 if the size is the same anyway

Its been mentioned before that that might be a typo. The dimensions and weight are exactly the same as the 70-200 2.8 OS, so I think we'll have to wait and see when it does come out whether or not they ruined it by making it big and heavy.

Oh, that could be a nice surprise then, I hadn't heard that rumor before. Guess we'll just have to see

Nah, they had the lens at the Photo show and someone took a picture of it mounted on a camera. It's as big as a 70-200. Might be lighter, though, since 200mm f2.8 is theoretically 33% larger glass than 150mm f2.8.

50-150 is SOOO much more versatile on APS-C, though. THat's 80-240 equivalent instead of 112-320. 80-100 are key portrait ranges for me. How many FF people would be happier if Canon cancelled the 70-200 line and made them 120-300? A few sports shooters, perhaps, but not the wedding guys.

I am put off with the size, but if you are going to lug a honkin lens around, it might as well not be so limiting on the wide end. The diff between 150 and 200 is a lot easier to make up for than 50-70, IMO.

definitely agree with you there. With so many megapixels to spare in recent model cameras, you can crop the difference between 150 and 200mm and still have plenty for a usable shot... doesn't make it the same, but it's not too tremendously different
on the wide end if you're using it for portraits or something, 50 can be alot more usable. Need a lot of working space for 70mm on a crop

I just noticed that this lens already has an official page on the Sigma's website:

http://www.sigmaphoto.​com …mm-f28-ex-dc-os-hsm-sigma

The size is almost the same as that of Canon 70-200 IS II, and weight is also probably similar. An overkill for a crop-only lens? I think I'm now less interested in this lens, given it's size.

Man I wonder when this lens will be available

I'm curious about this lens too, although with sigma I have the feeling we could be waiting a while before getting any news

As of today the lens/link is gone. It was there last week.

So, maybe it is gone;
OR just about to appear with new (lighter and smaller) weight and size!

we can only hope!

I'm of two minds so far as the size and weight are concerned. Sure, it's as big and heavy as a 70-200/2.8 but there are a lot of people (including me now that I have a full frame camera) for portrait work so it is not at all unreasonable to expect people to use this lens for the same types of work.

Then again, I'd rather carry my 50-135 than the 70-200 if I'm walking around.

I see definitely see what you mean...
The issue I have personally is that I would want it for a multi-purpose lens and in order to justify getting this instead of a 70-200 lens compatible with full frame, it would be nice to see a little bit of size and weight savings.
For some things I would appreciate the reach of 200mm but for others, the 50mm low end is really appealing.

I often wish for a little bit longer than 50mm for portraits and stuff like that but I like f/2.8 enough to keep a 17-50 (17-55) lens for a main walk-around/ all-purpose as opposed to using a 24-105, 28-135, etc
