a budget alternative for the pricey 24-70. great for film or fullframe users. It produces sharp images. Build quality is ok, and relatively light (compared to the "real" 24-70). It uses non-standard 72mm filters (I prefer the pro-77 size, but hey they cut the weight out of it).

sharp; nice build; (relatively) light; price

72mm filter; harsh bokeh

I bought actual canon lenses in other focal lengths now I am looking to replace this. There is no comparison. You do get some good images with this but not nearly as high quality. It has worked well for me for a few years. When you zoom in all the way does not focus well and extremely "soft" images.

I expected better image quality from this lens. To say that I am disappointed would be an understatement. I own other Tamron lenses that far exceed the optical qualities of this lens.

Great price for a 2.8 constant aperture. Lightweight. Autofocus is inconsistent and a touch slower than I hoped for. Range is not wide enough for a "walkaround lens" on a 1.6 crop camera. I have seen some excellent images come from this lens on other user's galleries.

f/2.8

Autofocus inconsistent; Lens filter size is unique to Tamron; therefore my other lenses require other filters

Highly recommend this lens. for the price it takes great pictures and I think the build Quality is great for the Price. Just do it you wont regret it.

Price is the Pro; This lens does a great job; You cant go wrong buying this len and adding to your collection; The 24-75 is great for wide and close up shoots,, like Parties and Weddings; the 2.8f stop allows you to tailor your cameras ISO to allow a blur free shoot in low lite.

Wished it shot wider than 24mm; 18mm would have been nice; Sometimes if you are not careful at what you are doing you may end up with a blown out picture because of the 2.8f stop; remember 2.8 will give you a background that is blurred so be careful to increase f stop if you want to capture a group...

I use this lens for portraits, events, and low-light shots. The fact that it is so small and light-weight is a definite bonus. The constant f2.8 really pays off in low light situations. Compared to the big, heavy Nikon, I really prefer this lens.

Consistent Output; Lightweight; Sharp Focus

Slow Focus; Weak Casing

These lens are great, and not just for the price. They are well constructed, feel nicely weighed in the hand, and not plasticky. They are reasonably heavy, but I see it as an asset, since it makes it easier to hold the camera steady. The output has been consistently sharp photos.

Consistent Output; Durable; Sharp Focus

Slow Focus

I have both this Tamron lens + my wife insisted on buying latest and greatest Canon EF 24-70mm f/2.8L II USM Lens. I tested both lenses and my not very professional conclusion is: 1) their sharpness is absolutely the same except 2.8 where Canon is a bit better 2) Tamron is lighter and more compact...

The Tamron 28-75 XR AF is one of my favorite lenses. It's hard to beat the quality, speed and price

Inexpensive; 2.8 aperature; quick focus; zoom lock; a good product overall

Body could be constructed tougher; could be sharper; sunshield is made of really weak plastic

I was pretty happy with this lens. For $500 it is just super duper great quality of pictures, especially sharp... Highly recommend everyone, worth each cent.
