Just a quick post about the D810. It’s been a long wait, but Nikon finally released the D810 documentation in the first week of September. We’ve now had a chance to test against the camera and everything is working as it should so we’ll be running a final test cycle and packaging ready for a release …
FoCal 2 is just around the corner, and we wanted to show you another new feature which will be available – the Calibration Check Test. This is designed to quickly and easily tell you if you need to calibrate your lens.
FoCal 2 is coming! It’s been a bit delayed because of some resourcing issues, but we’ve resolved that now and we’re full steam ahead on the FoCal 2 project. One of the new tests that we’ll be bringing in FoCal 2 is the Focus Shift test, and this post gives some idea of what it …
Reikan FoCal 1.9.5 introduces a brand new analysis method called RGB Analysis. This post is intended to give an overview of the benefits of this new analysis method – it’s quite technical so if you like getting into the details then read on! History of FoCal’s Analysis To start with, I’ll give a little …
It turns out calibrating AF Microadjustment is actually pretty difficult. Sure, there’s lots of information on the web about how you can do it with a piece of paper, but there are so many variables involved that a static paper target doesn’t really cut it for useful real-world results. At Reikan, I’ve been looking at …
Unless you’ve been hiding under a rock, you’ll have heard of the new Sigma 18-35mm F1.8 DC HSM A lens that’s now available. This is a really exciting lens as it’s the first to have a such a wide fixed aperture of f/1.8 across the whole zoom range. We had an opportunity to do a …
Focus Shift is a phenomenon which affects certain lenses and causes the point of focus to shift with a change in aperture. This post takes a look at why that matters, and some results from development testing of Reikan FoCal which allows the effect of focus shift to be quantified. Why does Focus Shift matter? …
This is just a quick post to show early development of a new feature in FoCal – the ability to test at both ends of a zoom lens and have the results interpreted for the best single result (or best dual results for cameras capable of accepting these): FoCal 1.9 is mainly focused on stability …
FoCal 1.0 was launched on 2nd January 2012, and since then there has been 8 major updates (free of charge), bringing the automated support from 2 to 20 cameras (and growing!), further operating system support and new tests and improvements to the overall software. We wanted to show how things have progressed over the last …
The last post about our HyperDoF refocusable image builder was our first about some of the research and development projects we do here at Reikan, but I wanted to tell you about another idea that we’ve been playing around with in the background – FoCal over WiFi! The Raspberry Pi If you don’t know about …
