Tamron 28-75 & Sigma 17-70

I'm in the market for a new lens for my K100D, and these 2 are the main ones working my brain. Along with the sigma 10-20, pentax 16-45 f/4.

I'm liking the tamron and sigma for their longer reach over the pentax. And liking the Tamron for the constant 2.8 apeture. But the sigma because it's wider end over the tamron. But I can't seem to find any pictures with the sigma 17-70 being used for concert/low light photography.

I know both are great lens, but how well would the sigma perform in low light? I also have the Zenitar 16mm f/2.8, which I was considering selling if I got the sigma lens. But keeping if I got the tamron lens. Thoughts, experience, low light or concert photos would be of great help.

Also, has anybody tried to use the 16-45 f/4 for concert photography?

TIA

I am in the same boat of deciding between Sigma 17-70 and Tamron 28-75. My preference goes to different one on different day. Today is Tueaday and I go for the Tamron. For your case with the Zenitar, I would prefer the Tamron for now and you can upgrade the Zenitar to a Pentax 10-20 or the Pentax 10-17 and have 21 limited down the line. So my lineup suggestion if I were you would be Tamron 28-75 with Zenitar 16 for now and later with Tamron 28-75, Pentax 10-17, some cheap wide prime like 24mm and 28mm, and finally when you can afford, the line up goes like this:

- Tamron 28-75 for walkaround & portraits
- Pentax 10-17 for wide angle zoom
- Pentax 21
- MF 28mm and MF 24mm prime for cheap

By the way, that is what I am thinking for my plan. And I have a write up for kit's replacement that contain three choices as in Tamron 28-75, Sigma 17-70 and Pentax 28-105 f/3.2-4.?

I'm getting the 28-70

Giving up my search-quest for the Tamron 17-50 right now. I found a local camera store
that has a Tamron 28-70 F2.8 XR etc in the warehouse. Its been ordered an i hope to get it by the weekend. I usually get 10% off from my salesman, so the price should be good. Plus they have a save the GST (5%) until Jan 15.

I'll let you know my findings.

At least it was in stock, not special order, so if there is a problem its easier to return.

Thanks for your input hinman. I'm kind of thinking the same thing, just go for the the 28-75 since it's a faster, and I own the zenitar 16mm. I also own 3 manual lens, 28mm f/2.8, 35mm f/2.8, and a 50mm f/1.4

Buydig.com had a great price on the tamron 28-75, but now it's out of stock. Can't remember the price, and now it's not listed since it's out of stock. But it was a lot cheaper than sigma4less and bhphoto.

I actually owned both the Sigma 17-70 and the Tamron 28-75 and got rid of the Sigma. I should mention that I have a Pentax 12-24 that covers the long end. The 17-70 and 28-75 where both supposed to be for walking around (with the 12-24 in my bag in case I need to go wide), for portraits and for low light photography (I was taking pictures at company parties which were always in clubs).

I found that the Sigma is a great lens if you don't already have a wide lens, but in my case it wasn't a good choise. I missed not having f2.8 at the long end, both for portraits and for low light photography. The Tamron is also noticably sharper (in my experience) than the Sigma - though the Sigma is quite sharp.

If you don't need the wide end of the Sigma, I'd recommend the Tamron. If you only want to carry one lens and be prepared for a lot of different shots, the Sigma really cannot be beat (I mean it's macro ability is awesome, for a zoom :-) ).

I was in the same position and was looking at the Sigma 24-70 f2.8, the 24-60 f2.8 and the tamron 28-75 f2.8

I need f2.8 for some low light things I do, and that was one restriction I put on things.

I was initially looking more towards the sigma 24-60, principally because it used common filters to my Sigma 10-20, and my 70-200f2.8, my 300F4 and 400 f5.6

It seemed that I had a lot of 77mm glass., but then I looked at the tamron, which by all reports is the best optically of the three. It has 67mm filters, and this is also the same size as my 18-35 pentax and my old vivitar 70-210 f3.5. Turns out, I am better off with the 67mm filter as I already have a polarizer and 2 differfent graduated ND filters.

In the end I took the tamron, and am please with it.

If I get stuck needing something between the 10-20 and the 28-75, I will still have my Pentax 18-35(it was the kit lens on my *istD).

Just as a note, I stayed away from a digital only lens, not out of fear that pentax will go full frame, but because I still have 3 film bodies, including a very capable PZ-1, which acts as a back up.

Aside from the sigma 10-20, all my glass is full frame, and until I decide I will no longer shoot some film, even if for enjoyment, b&w or what ever, I will try to keep lenses compatible both ways,

Hi Hin,
Wow we are in sync again on our lens desires. I have decided I want the Tamron 28-75 f2.8. I am hoping the 2.8 will be fast enough for the kid shots.
And it seems like the perfect portrait range. I wish it was a bit wider at the 28 end but I need something to take pics of the kids and the zoom seems more versitile.

I can not afford to get it till my company bonus comes thru. So if you get it first you must tell me what you think!

I have also been thinking about getting one of these lenses. I would love to get the sigma for it's wide end, but the the F/2.8 is hard to pass up on the Tamron.
