The Carl Zeiss Planar 1,7/50 is reputed to be one of the sharpest normal lenses and also the cheapest Carl Zeiss you can buy. In this in-depth review I put it to the test.

Most rangefinder lenses used on a Sony a7 series camera show some serious issues because of the rather thick filter stack in front of the sensor. There are two ways to deal with this. We have previously discussed the use of front filters to counter the induced field curvature. In this article Sebboh reviews another solution.
This is an extended use review of the Kolari Ultra Thin (UT, also sometimes referred to as version 4) sensor stack modification on a Sony A7. This modification removes the AA filter and IR cut filter from a stock Sony camera and replaces it with an ultra thin 0.2mm thick IR cut filter in order to attempt to provide similar levels of performance to the Leica M9 in dealing with the steep ray angles often produced by rangefinder lenses designed for film. I have shot a UT modified Sony A7 for 6 months now and can confirm that it dramatically improves performance with certain lenses (big thanks to Nehemiah for letting me use his lenses and cameras for the comparisons shown here). I will try to outline what kind of improvements can be expected here and what drawbacks there are to getting the conversion done.

Macro lenses around 100 mm are among the most popular primes because they can be used for a very wide range of applications. So, how did Sony’s 2.8/90 turn out? Check out my review for the in-depth analysis.

The Jupiter-11 135mm 4.0 is another copy of a Zeiss lens, this time the Zeiss Sonnar 135mm 4.0. This one is really cheap, but is it also as good as the Jupiter-9 85mm 2.0? Let us find out!
40mm. One of my favourite focal lengths. Long ago the Voigtländer 2/40mm Ultron was glued to my Canon. Even longer ago, the Zuiko 2/40 was a favourite on my Olmpus OM film gear. The 40mm equivalent 20mm Lumix was my favourite lens on the M43 gear I used to use for travel and hiking. So naturally a native 40mm full frame lens for E mount has me very excited.
That slightly wider than standard lens look (close to the theoretical ‘normal’ focal length of 43mm) gives a lovely, natural perspective that leaves the photographer, rather than the angle of view, in charge of the image. But of course the cost of the slightly wider angle of view is less potential for bokeh; the nice, isolating, out-of-focus blur that people prize in people photography. That’s why the speed on this lens is potentially so great. Perhaps f1.2 sounds extreme, but the actual blur potential is about the same as f1.4 on a 50mm lens. So in order to keep up with a 50mm lens in terms of blur, you really do want a bit of extra speed on moderate wides. 40mm is a great length for portraits which place people in a context: but you don’t want that context to dominate, so being able to see the context but have it nicely blurred is a fantastic combination. But what price do we pay for that? Is the IQ on this surprisingly small and fast lens good enough? Thanks to Mainline Photographics who are the Cosina Voigtländer distributors in Australia, for the loan of a review copy.
