Tamron 20-40mm FE review by SonyAlphaBlog: “ideal only if you really need the variability of a zoom”

The lens at BHphoto. Adorama. Amazon US&EU. FotoKoch.

SonyAlphaBlog tested the Tamron 20-40mm FE lens and concluded:

The Tamron 20-40mm F2.8 Di III VXD (999 euros) , is proposing a usual zoom range that will suit vlogger , and photographer who mix street and architecture/landcsape and a tiny bit of portraits. It will also be an ideal complement to a Tamron 35-150mm F2-2.8 Di III VXD

Its performances are very good overall with very good sharpness especially at 20mm but nothing excellent neither specially in the corners that are a little bit weak at 40mm wide open. For best results across the frame you will need to close down to F5.6 . Bokeh is very good, as well as color rendering and smoothness of background blur

The images are automatically corrected in Lightroom for distortion and vignetting. Resistance flare is a bit average

In term of competition there is no direct equivalent the best replacement are either

The Tamron 20-40 will be ideal only if you really need the variability of a zoom , a F2.8 and this specific focal range and will be more at ease on a A7IV (33Mpix) than on a A7RV (61Mpix)

Sony A7rV review by CameraLabs

In Australia at CameraPro, Camerahouse, Sony.

CameraLabs finalized his A7rV review and concluded:

By becoming more practical for long exposures, macro photography and pixel-shift composites, the R V broadens its appeal, while also giving you the flexibility of a tilt and flip screen, the joy of the most detailed viewfinder around, the bonus of 8k video and Sony’s most cunning AF system to date. I can definitely recommend it, but whether it’s worth the extra thousand? Only you can say.

One more review from Sidney:

First worldwide review of AstrHori 12mm F2.8

SonyAlphaBlog reviewed the new lens and concluded:

The AstrHori 12mm F2.8 Fisheye (259$ / 349 euros) is a very good Full frame fisheye lens. Its is build like a tank , its ergonomic are very good (nice click aperture ring and well dampened focusing ring).

Its performance are very good overall with very good sharpness on the entire field as of F8, very good color rendition, nice background blur, very good resitance to flare. Its only weaknesses are the sharpness in the corners between F2.8 to F5.6 being only good on 61Mpix, and the sunstars that could be better defined

This is cool: Size comparison between the first generation A7r and the new A7rV

The Japanese website Champcamera compared the very first A7r (announced in late 2013) and the brand new A7rV. Five generation of cameras after the “r” series really did grow a lot in size.
