Photokina 2014 – Sigma 150-600mm F5-6.3 DG OS HSM | S on Sony A7r – hands on

There were many new lenses on this year Photokina and one would need much more time than I had to try them all. So, while I was mainly interested in Sigma Art series with their excellent 50/1.4 and 35/1.4, I couldn't resist to put this new Super-Tele Sigma on my Sony A7r. It happened many…

Extremely Swirly Bokeh – Short Tutorial

Here is my story... Over years, I collected some 20+ Helios 44 lenses. (If you never heard of this lens, it is Russian copy of Zeiss Biotar 58/2, one of my favorite standard lenses). I did so partially out of curiosity to see how many variations I might discover (it is believed that anyone who…

10 minutes lens test – portrait session

I can't say what is harder - finding "Perfect Lens" or finding "Perfect Testing Method". Especially knowing that neither exist.I published many "controlled" tests, mainly using ISO 12333 chart, but those charts and walls usually tells only part of the story.Unfortunately IMHO, most readers are referring to MTF tests and results, in general terms, considering…
