STOP, don't buy new. Used value meter pegged...
on June 7, 2017
I bought this lens used as a backup lens or for a second shooter for use on a full frame Canon (5D mkiii & mkiv). It represents an incredible value, especially used, I bet I could use it for a few years and sell it a loss of less than a Benjamin. But beyond being inexpensive it's a sharp lens! I'm not sure why this doesn't pop up all over youtube when you search for a good starter lens, it's relatively obscure. Don't just take my word for it, check DXO Mark's web site for a rating, compared to Canon it's superior in several aspect, not all of them, but it's also 500-800% less expensive. If you're looking for your first sharp lens with shallow depth of field I'd recommend this over the nifty fifty or 85 f/1.8 - if you could only afford one lens, ditch the kit lens, book a model and go shoot with this lens, you will love the results.
Flaws are easily correctible in Light Room
f2.8 is useable and close to the actual transmittance (it's a fast lens)
Beautiful out of focus area
Very light weight
Mild macro capabilities
Autofocus is slower than the comparable Canon and it hunts just a little but a 1/2 second of patience isrequired for the best shots. Focus on breath control & brace just a little while it finds the exact focus
Appearance of the build quality but if you like the low weight, it's probably a function of that
Looks inexpensive & perhaps dated - for paid gigs I'd keep this in the bag for a backup or until you've showed off a lens with a red ring
Autofocus mode is not full time override, you have to flick the manual focus switch to manually set focus. I'm only mentioning this because this seems to be a point most reviewers will point out about a lens but there is a plus side of this - once you find focus, if you use back button focus, the lens elements are locked down and will not creep - great for astral photography when you've got the camera aimed up high.
As an aside, there is obvious vignetting below f/4 which could be a problem for landscapes but if you're using Light Room, the program has the Tamron 28-75 corrections programmed in, just check the box and it will be corrected. For portraits I can see myself shooting wide open and adding a little extra vignetting in post so this is a non issue for my style.
To help with the look and also lens flare (which appears well controlled in my anecdotal home test) amazon sells an OEM Tamron lens hood. https://www.amazon.com/dp/B0010CDWIY/ref=cm_sw_r_cp_dp_T1_vEiozbW0EYWY1
I've attached two photos, the one with the chart in the center was taken at 75mm, about 8 feet away, and at f/2.8. It should give you an idea of the depth of field. You can see the photos on the wall, about 20" away are nice and softly out of focus. You can also see the vignetting at f/2.8 since I didn't correct for it. I also didn't correct for chroma. The second photo is real life - one of my dogs. She was moving around but even with the slow focus I was able to lock in - I added a little extra vignette and processed contrast and colors to taste in light room with only the remove chroma option selected.
