→ Lensrental published their MTF test results for the Sigma 85mm f/1.4 DG HSM Art lens ($1,199): "From an MTF standpoint, it’s better than any other 85 except the Otus, and it makes a very respectable showing against that fine lens" (they tested the Canon version).

Another camera magazine find- this is an article on the Nikon SP 20, a mock-up of an interesting compact camera that never went past the design phase. It had a 24-80mm f2.8 AF lens which could also be manually focused with its rangefinder, an auto film advance, and was designed in the spirit of the earlier RF Nikons. The article said this was spotted at the Nikon booth at a camera industry fair and that the staff on site were not able to say much about it. (Online sources say it's from 1990). The writer noted that the film plane was far too close for either 35mm or APS film and concluded that it was merely a Nikon designer what-if side project to test industrial design ideas. Funny how there's probably a market in 2017 for something new like this. #NikonSP20
