The full frame sensors are beginning to reach resolution of 50 megapixels. Is it creates some additional requirements when designing lenses? Does the older models of Sigma lenses, presented about 5 years ago will meet such extraordinary resolution requirements? Yes, we need to achieve the better performance both in the lens design and manufacturing to support such super high resolution cameras.
During the last seven years we’ve managed to test 30 different polarizing filters. There have been surprises, good and bad ones, disappointments too. One thing is sure: in that time many of companies have gone out of business and many new have been created; big corporations have changed suppliers of half-finished products and accountants.
It seems people have strived to capture photos in the quickest successions possible using the cheapest possible cameras since time immemorial. Perhaps I am exaggerating a bit but there is something in it.
Question: How come You happened to become an optics specialist? Answer: My major at the university was the Space physics. While using telescopes, I started being more and more interested in the optical measurement equipment.
Kazuto Yamaki - CEO of Sigma Corporation was visiting Poland in the beginning of November. We had opportunity to meet him and ask several questions. Arkadiusz Olech: Welcome and thank you for finding the time for our interview.
Underwater tests in Sharm el-Sheikh Holidays are approaching fast; small wonder we have been to Egypt for the fifth time to test the newest models of waterproof compact cameras. There are more and more such products every year – that fact forced us previously to divide our test into two parts because during one trip we weren’t able to test all of them.
We were given an opportunity to get acquainted with the newest Leica X2 camera model several days before its official launch. We tested its functions and found out what changes had been made compared to its predecessor.
The third part of our cycle „Polish people have also something to boast of...” in which we have been describing a history of Polish Optical Industries, is not a direct continuation of the PZO history.
We are continuing the history of Polish Optical Industries. Let’s just remind here that the first part of the article encompassed the beginning and a very quick development which was stopped all of a sudden by the onset of WWII.
We’ve already featured series of articles describing the history of such companies as Canon, Leica, Nikon, Olympus and Sony (available only in Polish on Optyczne.pl). Many people have been asking us afterwards to publish next parts, with the history of others foreign optics producers.
While discussing our tests we’ve met several times with controversial statements about the colour rendering different binoculars or lenses offer. More particularly these doubts concerned why we assess the white rendering of older Russian, Polish, Romanian and Czech products so low, including also the binoculars which were produced by Zeiss in Jena.
The holiday season is being in full swing - it means the time has come for the test of underwater cameras. It’s become even more necessary because all the models, tested by us one year ago, have had their successors launched.
When we published the Voigtlander Color Skopar 20 mm f/3.5 SL II Aspherical and the Voigtlander Ultron 40 mm f/2 SL II Aspherical lens tests once again we were questioned about the differences between resolution results presented on the Optyczne.
As we are often asked similar questions - on the forum, in mail and in comments under tests and news as well, we decided to start a FAQ section which we are going to enlarge successively. Enjoy your reading! Why do you use just one specimen of lens, camera or binoculars in your tests? Why do you test lenses on such an old body as a Canon EOS 20D? Why don’t you test vividness, colours and bokeh? Why do results, presented on the Lenstip.
Originally posted 2010-05-26 on Optyczne.pl Our last year’s test of underwater cameras has been very popular. Small wonder we decided very quickly to conduct it this year too, especially that during the last 12 months we saw the next crop of waterproof point and shoot cameras hitting our shelves (we also invite You to read our \"Underwater cameras test 2011\").
