Re: Vielen dank für alle intressante antworten There are some more aspects regarding AF and "digitally designed lenses". A very unknown optical defect is variability of back focal distance. Just to explain: You have a lens like a 28-70 2.8 set to 40 mm zoom position. Due to the automatic...

... continued From my experience, this is the tradeoff for lens compatibility. The whole photographic world was based on a resolution circle of 30 microns or for some enthusiasts 15 microns on film. So all components had to meet this spec. Now we have sensors with 4 micron pixel pitch on one...

Re: Vielen dank für alle intressante antworten Hello IT Sundvisson, Thank you very much. It is my pleasure. In some German communities people feel, they have the absolute right to get answers for all of their questions, no matter how much time the "interrogated" spends or whether he touches...

To TI Sundvisson Sorry, I can not cite your posting, because you have added charts to it. Therefore I will copy and paste and mark them: > Questions on sensor technologies >1. >How does the Foveon X3® Direct Image Sensors and >the Fujifilm Super CCD Type HR (High Resolution) >and Super CCD...

Hello Martin, usually there is a analogue amplification before A/D conversion. There is also digital amplification possible, but if you enhance a stepwise signal, e.g. the digital signal, no matter if it happens on 8 Bit or on 10-11 Bit, you widen the stepwidth. Regarding tonal reproduction...

Re: Questions on sensor technologies @ Wow, you're a tough guy :-). These are very interesting questions and I will be happy to answer them. My answers will be may be different from what you expect, because I do not rely my evaluations on data sheets. It is good to know the photon capacity...

Hello Mikael, the problem is, that the camera internal signal processing is extremely complicated and RAW is not RAW data. From the technical point of view your two exposurers will put the same number of photons on to the sensor. Therefore the number of electrons and the primary voltage on the...
