Pick one: Pentax 50-135 or Sigma 70-200

I would like to upgrade my kit of lenses, especially for concert's use (small venue, where is possible to take pictures, as at the big concert is not permitted and as I'm very tall the security can catch me very easy - I try to stay in the pit near the stage), but I'm unsure wich one to choose.
Pentax is lighter, Sigma quicker. I really don't know what to do. Which one is better at TA and bad condition of light as at the concerts? And the problem of sdm failure? At the other hand the Pentax is maybe more for universal use then Sigma.

Having tried both, but owning non of them, I'd pick the DA*. The zoom range is indeed more suited for cropped sensor and bokeh is nicer too I'd say. Problem of motor failure is today equally possible for both lenses. With DA* you can crop to get smaller portion of the image, it also seems to work better with TC's (like AFA1.7x).

Vote for Sigma. It's heavier but HSM is much more faster and more reliable too. Between 100-135mm Sigma is razor sharp

If your trying to be discreet (at the concert) than I'd pick the 50-135

Since you mention shooting smaller concerts, i vote for the DA*. My old 80-200mm f/2.8 always felt a tad too long in smaller venues.

I personally prefer the 50-135 -- smaller size, quite sharp. The Sigma 70-200 is really a very large lens (I haven't tried the OS version). I also like having the 20mm on the wide end more than I would need the 65mm on the long end.

I have both. It depends on what you need it for. Sometimes the 70mm is too close and sometimes the 135 isn't close enough. But I do like the ability to focus closer in with the 70-200 than I can with the 50-135. But the IQ of the 50-135 is to die for. And then there's that whole SDM thing . . .

This is a frequent question.

I use the 50-135, for events. If you can get fairly close, the 50-135 is really good.

I only have shot with the Tamron version of the 70-200 for comparison. The size of the 70-200 lenses are just too much for me personally to shoot for long periods. The one time I shot with the 70-200 was at an event where the organizers let me bring in a tripod and gave me a place to stand and take pics of the stage beforehand. In that situation, the 70-200 worked really well. On the other hand, if you going to be very close to the stage, you might want to shoot wider and then the 50mm end helps.
Disadvg: The AF speed of the pentax is not great though. But should work fine in most situations. Once you use it enough you will know what you can do with it and what not.

If you're also a big outdoors shooter go for the Pentax, otherwise the Sigma's reach and faster af is probably what you'll want.

Had similar concern for quite sometime and I eventually picked something else, Sigma 50-150 2.8 (the old version without OS). It's HSM so it's supposedly faster in focusing and there's no worrying about SDM failure. Also, while 135mm and 150mm isn't significantly different, it's at least closer to 200mm (require less crop to mimic 200mm FOV). It's also still very small and light compare to 70-200.

A win-win solution in my opinion. Only problem is to locate one because it's been replaced with the new version with OS, which is unfortunately bigger and heavier due to the OS (besides we don't need OS). I was lucky to find one in a local shop recently and snatched it right away.

For that I would buy the DA*50-135mm, it's small and sharp. Focussing isn't very fast, but the subject is on defined location on stage, so that won't be the biggest problem.

This one is made with FA*85mm

Also use DA*55mm for such things (but not often). Dragging around a big lens gives oppertunity's, but then there is no way of being discrete. You can buy a DA*200mm/f2.8, but then you have two lenses.

50-135 by 135 at is a bit soft...
I treat 50-135 more like a potrait lens..
just like many pro use nikon or canon 70-200 as main potrait lens too( full frame).
for sports, concert kind thing I think 60-250 is a better choice..more range

Thank you for your advice ... Probably I will choose the Pentax: is lighter, more "universal", maybe a little bit soft, but for my first lens I think that is not so bad
