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.

Sony A6500 vs. Sony A7II comparison – which one is the smarter choice?

With the Sony A6500, Sony has entered the terrain of semi-professional crop cameras. The camera is significantly higher priced than other Sony APS-C cameras, and is directly competing with other smaller format flagship cameras like Fuji X-T2, Nikon D500, Olympus OMD-EM1 Mk2 or the Canon Eos 7D Mk2.

Furthermore, the Sony A6500 is now similarly (or even higher) priced than the Sony A7II. This leaves open the question for many people as to whether they should really spend that much on an APS-C camera, or if they should get a full frame body instead. The comparison is obvious, and legitimate, because the cameras share a few key specifications – like sensor resolution, mount, and sensor stabilization. Let’s check what sets these cameras apart from each other.
