Beginner’s Guide to Manual Lenses on the Sony a7

Okay, everybody is talking about how manual lenses work so well on the Sony a7 series but how does it actually work? And which results can you expect? Read on if you want to know.DSC00720

Manual Lenses on the Sony a7/a7II/a7III

Zeiss Distagon 2.8/28  ~ $250
Olympus OM 2.8/100 ~ $100
 Minolta MC 1.4/50 ~ $60

Why should I use manual lenses?

    • They can be very cheap, you can get a great 1.4/50 lens for $50. For most applications such a lens will give you 90% of the performance of a $1000 Zeiss 1.8/55 FE. For the $1000 you would have to pay for that Zeiss you can buy an excellent set of five lenses from 20 to 300mm.
    • You have a huge choice between thousands of lenses ranging from exotic ones with lots of “character” to some of the very best lenses available.
    • There are 30-year-old primes with better image quality than many modern lenses. Of course progress has happened in recent years but still affordable primes are often sharper than very expensive modern zooms.
    • Old lenses are usually beautifully built from nothing but metal and glass which makes it a joy to handle them. They can last a lot longer than modern lenses which are full of electronics and very complex designs, both of which make them more likely to fail.
    • They also hold their value much better than modern lenses. With some patience you can sell most manual lenses without a loss but with new lenses you can expect to lose 30% in the first year.
    • Manual focusing can be very enjoyable. This certainly depends on application but personally I enjoy working with fully manual lenses a lot more than with any AF lens and I would choose a good manual focus lens over an AF lens (almost) any time.

Travel report: A journey through the Balkans

Travel report: A journey through the Balkans

Last two years I already visited (by airplane) the Balkan countries Montenegro and Albania for a hiking vacation with my girlfriend and a photography trip with my photo buddy Rick. The wild nature of the Balkans attracts me a lot. As the Balkans are not well known yet, and a lot of people from West Europe think its still dangerous there (most area’s are safe nowadays), you can walk around in the mountains without seeing anyone for a whole day.
The Balkan countries also have very nice, often old cities at the Adriatic coast which are touristic, but not nearly as those in e.g. Italy.

Below you can find a few pictures from my trip last year, which convinced me to go back again this year.  Most photo’s of this year can be found in high resolution here. The timelapse video my friend Rick made is also worth checking.

Review: Kolari Ultra Thin Sensor Stack Modification

Cover glass from the Sony A7, A7II, Kolari version 2 mod, and Kolari Ultra-Thin mod (from Kolari’s website )

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.
