The Industar-69 is a strange little vintage pancake lens with unique characteristics. In this video we show you how to adapt it to a Sony E camera with our Fotodiox M39 to Sony E adapter.

Here is a bunch of new reviews of this lens:

The new Voigtlander 28mm f/1.5 Nokton for Sony FE is now in Stock at BHphoto (Click here). And here is the world’s first review published by SonyAlphaBlog:

Sharpness is excellent for long distance but results are a bit disappointing at portrait distance with only good results wide open for portraits
Background blur is very soft, colors and contrast are very good, Bokeh balls are excellent. Resistance to flare is good and distortion very small. CA and Vignetting are quite significant

Christopher Frost has published a review of the Sigma 300-600mm and he really likes the lens:

Northrup tested the L-mount version of the lens:

I found those two recent reviews of the first original RX1 and the latest RX1rII. Both cameras are only available used on eBay or reconditioned with warranty on Amazon.

Sony RX1 vs Sony A7cII:

And here is a long time review by Andre Mey (German).

The new Sigma 16-300mm lens launch got a bit undermined by the gorgeous 300-600m launch and the curios BF camera. Chris from PetaPixel tested this lens and concluded:

I expected the optical issues that are inherent to the design of a superzoom and despite them, still had a wonderful time traveling with the 16-300mm lens. All’s well that ends well when you go through your photos and treasure the results.

Here are a few size comparisons to give you an idea of the size of the new Sigma lens. It’s basically the same size as the Sony 600 GM, but weighs 1kg more. The good news is that it costs less than 50% of the Sony lens!
