    Come play with the Canon EOS R RAW files

    I have measured the dynamic range from the RAWs. It seems that the EOS R exactly matches the 5D4 performance, except at ISO 100, where it has around 0.2 EV less dynamic range compared to 5D4. Maybe not that bad taking into account that the sensor is now permanently switched on. EDIT: that could...

    Opinion: Changing Canon camera lens mounts. How might the RF mount affect you?

    I appreciate a lot Keith reviews and analysis on his site. As he has noted, the Sony FE mount is about the size of EF-M. But no, Sony engineers are not limited by it: in fact it is still wider than 54mm (Canon EF) when "projected" to Canon EF 44mm flange (while at the same time allowing for...

    Is the new Canon full frame mirrorless called the EOS R?

    You have just summarized what I have been thinking in the last weeks. The Canon mount could be wide enough for that use. Only wide angle lenses take advantage of short flange distances: these lenses could be redesigned for "the new mount" as you say. The rest of the current Canon collection...

    Want to Increase The Dynamic Range of Your EOS 5D Mark IV Raw Files?

    I think that the current DPRAW implementation by Canon has not the properties required for a job requiring critical quality. Beyond than blending issues there are other artifacts which can be noticeable: http://www.fredmiranda.com/forum/topic/1453555/0 For example, take a photo of a evenly...

    Canon EOS 5DS R Mark II Talk [CR2]

    I hope the AA filter version is still available on 5DS mark II. Take a look at the balconys on this image at F4 (at the platform at the far left, or in the buildings): https://3.img-dpreview.com/files/p/TS8256x6192~sample_galleries/7707853581/3016826142.jpg Not a 5DSR, but the last shocking...

    Clarification & Corrections on the Upcoming New Lenses from Canon [CR3]

    Re: Clarification & Corrections on the Upcoming New Lenses from Canon [CR2] I have a question about TS-E "long" lenses for architecture. For architecture it is extremely useful shifting a wide angle lens: it removes the highly distorted areas close to the photographer, placing more emphasis in...

    Few 1DXII samples

    Many thanks for your files!. If you manage to upload a single ISO 100 CR2 file (I don't know if you are allowed to) I could quickly analize the low ISO dynamic range, using the same method applied to the 80D on this thread http://www.fredmiranda.com/forum/topic/1419472. Likely the 1DX2 is even...

    My hands on with the 1DXII

    Thanks Eldar. If you got a ISO 100 raw file, it would be possible to measure the sensor dynamic range using the masked pixels technique and a suitable decoder (like dcraw with some hacks). ISO above 400 wouldn't be so interesting because it is likely that it will have not a huge improvement in...
