Build Quality / Ergonomics / Handling
The lens made by plastic, it is dust and moisture resistant. However, my slightly long nails leave some white marks on the lens, like fingerprint magnet. The lens is lightweight and looking average. Lens hood feels plastic and loose (not really). It has weird lens zoom ring replacement, I definitely need some time to get used it, feel right after one whole day using the lens.
Focus
Auto focusing is very quick like instant, and quiet, I don’t find anything focus haunting, even in very low light situation.
Manual focus is focus by wire lens, like most Sony lens. The manual focus ring is quite narrow, it still feels nice to manual focusing and comparable to my Sony 90mm f2.8 macro lens.
Performance / Sharpness
Almost ⅓ price of Sony 24-70mm f2.8 GM, and you get nearly sharp images (or better) and performance with this lens and at this price! Images are tack sharp at wide open f/2.8. I find f8 really good for cityscape and smaller landscape, and f/11-13 is great for huge landscape. This lens is sharp at any apertures (maybe exclude f/22).
The lens got extremely good minimum focus distance to shoot some close up shots, 19cm distance @28mm and 39cm @75mm. I like to macro with Sony 90mm f2.8 macro lens, although this Tamron can’t do what a macro lens able to shoot, this lens offers the versability that everyone would like.
Distortion and vignetting, can be easily fixed in Lightroom but still need to be careful when framing your shots.
Bokeh is what I expected from a zoom lens. The bokeh is very smooth at 28mm and f/2.8. It has onion ring bokeh and bokeh looks busy at 75mm, not a dealbreaker for me.
Pros
Low price and quality lens, it is very worth to get this lens for the price than Sony 24-70mm f2.8 GM and the image quality is comparable or on-par to GM.
Awesome minimum focus distance for close up and macro shots at wide, across the range and long end.
Weight, I can hold this lens for very very very long time (4-6 hours or longer).
Great color, the color rendering is superb and fair skin tone.
Cons
To be honest here, no any cons at all…
24-70mm to 28-75mm (it might be cons for other people), it just 4mm difference and I don’t shoot at wide often these days nor I always need 24mm for my shots.
Plastic body, of course the build quality is not like Sony GM & G zoom lens metal lens body, but this is is lightweight
No AF/MF switch and focus hold button like Sony zoom lens, I had customized a camera button for AF/MF, focus hold button could make life easier, but for this lens price.
Distortion/Vignetting at 28mm, but easily fixed in Lightroom
