Tamron 28-75 2.8

[birdfish]

Trying to decide if I should get this lens. My camera body is a T3i crop sensor. Right now I only use primes, 5omm 1.4 and 85mm 1.8. My sessions are mainly children and families. I'm hoping to find a lens that will allow me to zoom in quickly for tight close up shots but then zoom out to get full body shots as well. I love the prime lenses I have and I'm worried about sacrificing quality if I go with this lens. Would this be a good choice for child and family photography like I mentioned above? I'm planning on selling my primes to foot most of the bill for the Tamron but I'm nervous that I will regret it. Any thoughts or suggestions.

Eh...I wouldn't sell your primes to get it.

There's nothing wrong with the lens per se. I own one, and I use it pretty regularly. But it's not as sharp as my primes, and honestly, in most situations like you are describing, you usually don't want anything shorter than a 50mm focal length for portraits.

It's also kind of a weird zoom range for a crop sensor (45-120mm)...although maybe not terrible for portraits.

If you wanted a zoom for that camera, I'd probably recommend something designed for crop sensors. I really liked my Sigma 17-70mm f2.8-f4 when I had a Canon SL1. I used that thing for everything, and it was super sharp.

A couple of examples...

You can get one for less than $300 used.

There are also great lenses from Sigma and Tamron in the 17-50mm range that are very nice and similarly priced...I just liked the extra zoom.

I'm in this camp. I'd wouldn't sell two decent lenses for one sub-par one just for zoom.

This Tamron is really best suited for full frame, if you plan on going full frame in the future then its not a bad choice.
Personally I would recommend you to consider the Sigma 17-50mm 2.8, its an APS-C lens and if you don't plan on going full frame it will be a better lens.

Another thing to mention is be sure this lens has auto focus on your camera, I don't know Canon so well as I know Nikon and this Tamron will not auto focus on lower end camera like your T3i, it will auto focus only on higher end bodies in Nikon line up, just check it if you are going to buy it.

I agree, don't get the Tamron. keep the primes. if you want a better a zoom look at the Sigma 17-50 2.8 EX DC OS HSM

Don't sell good lenses to buy unknown lenses. Put another way: do not sell good lenses. KEEP good lenses!

I'll look into that lens. I love the chocolate lab!! So since it's designed for crop sensors, is it truly 17-70mm or really closer to 27-112?

Thanks for all the suggestions everyone.

>>SNIP>>>So since it's designed for crop sensors, is it truly 17-70mm or really closer to 27-112?

it's truly a 17mm to 70mm focval length zoom lens. It truly is what it states it is.

Buuuuuuut....it behaves "sort of as if" one had a 27mm to 112mm zoom on a full-frame or 24x36mm capture area 135-format camera. No "exactly" the same, since each film or digital format size behaves a slight bit differently, but close enough to use the comparison of "full-frame angles of view".

Lenses designed for smaller sensors have real,legtitimate, acctual focal lengths, marked on them. The focal lengths (FL) are real,measured things. The curent new term that some people are using, in order to translate how a lens designed for APS-C behaves in real life photography is "e-View"....or "equivalent View"....

One takes the ACTUAL focal length, say a 23mm f/2 lens designed for a FujiFIlm camera and its APS-C size sensor, and multiplies that by 1.5x or...and you get 23mm x 1.5 Field of View or FOV factor, and the multiplication yields 34.5mm e-view; Sooooooo, on say a FujiFIlm X-series camera, their 23mm f/2 prime lens is a 34.5 e-View lens; close enough to be used AS IF IT WERE a 35mm foval length film camera lens, or a 35mm lens on say, a full-frame Canon or Nikon d-slr.

Excellent explanation, thanks so much Derrel. JonA_CT mentioned the Sigma 17-70 2.8-f4 what are your thoughts on the Sigma 17-50 2.8? I would prefer having the fixed 2.8 all the way through rather than the extra reach. ve read lots of good reviews on it, it's in my price range, trying to make my mind up.
