Richard Wong released his review for the Tamron 17-28mm f/2.8 Di III RXD FE using a preproduction copy.
- The Lens is plastic
- It is very lightweight
- It is very compact
- Plastic lens hood that provides pretty good protection
- Zoom and Focus ring
- 67mm front filter that is the same size as the Tamron 28-75mm
- Weather and Dust proof
- Very good AF that is fast and smooth making very little noise at all
- Works on the Nikon Z cameras with Techart AF adapter
- Center sharpness very good wide open with a 24mp camera
- Stopping down doesn’t really improve the center
- Corner sharpness is very good at f/2.8, but is a little softer at 28mm
- Corners become very sharp by f/5.6
- Image sharpness is good across the whole focal range
- If you shoot at f/4 across the range you should be pretty happy with it’s sharpness
- 17mm f/2.8 a little vignetting which is a little better by f/4 and pretty much gone by f/5.6
- 28mm f/2.8 vignetting barely noticeable and gone by f/4
- Quite a bit of distortion across the whole focal range
- Bokeh is ok but if you zoom in there is some onion ringing in the bokeh, but only zoomed
- Lens flare and ghosting is very well controlled
- Chromatic aberration is well controlled too there is very minimal color fringing
- Distortion control is the only thing that could be a little better
- Surprised they didn’t go to 12mm or 14mm, because stopping at 17mm is a little odd, but was probably done to save money and bulk.
- This design philosophy is similar to the Tamron 28-75mm that stopped at 28mm instead of 24mm, but it turned out to be a very popular lens.
- Hopefully the 17-28mm will be another super popular lens among Sony shooters
- This is a very god choice for Sony APS-C users too
- G Master has better build quality and covers more of a range, but it’s twice the price and it is bigger and heavier
- Don’t see how Sony 16-35mm can be that much better than the Tamron 17-28mm f/2.8 Di III RXD FE
- The Tamron 17-28mm f/2.8 Di III RXD FE will give you the most compact setup for your Sony camera system
