Carl Zeiss C-Sonnar T* 50mm f1.5 ZM: A Detailed Review

We have become used to old lens formulas being revived and sold for occasionally huge sums of money to collectors and photographers hoping to create images with a magical vintage look. All of us here have been very sceptical about this. Mostly they have been simple lenses in simple bodies with poor technical qualities being sold for more than the price of the latest and greatest glass. From one perspective the legendary C-Sonnar from Zeiss is like this. It’s a classic design dating from 1932 whose principal design goal at the time was to reduce the number of air glass surfaces because the coatings of the day were so primitive. Why do we need it now? But Zeiss bought it back in 2006 in M mount as part of the ZM series. The optical design is not much changed, but it comes with modern coatings. Many prize it for magical rendering and flattering portraiture, others think it shows that not even Zeiss is above trying to rip off nostalgic hipsters. Read on and find out who is right!

Carl Zeiss Tele-Tessar (ZM) T* 4/85: A Detailed Review

The Carl Zeiss Tele-Tessar T* 4/85 lens was released in late 2008. It is a ZM lens designed for Leica rangefinders, with a very pure long-focus five element three group construction. 85mm lenses may well not suffer from any issues on unmodified Sony sensors, and it’s light and compact for a high quality short tele. It has a reputation for being a wonderfully sharp and contrasty: is it good enough to be a great companion to your Sony, despite being relatively slow? This review may tell you.
