Should I use a SD to CF adapter in my older camera?

The primary advantage of the former is that it avoids necessitating the purchase of a CF-USB adapter to upload photos to my computer (and from thence to my hardrive). If this is your main reason then ...

Neither the 1D X nor the 5D Mark IV are "weatherproof." Canon refers to both as 'weather resistant'. If you use either in the rain and water damages the camera it is not covered under warranty. The ...

Why does 5DSR have a low pass filter?

At the most basic level, one can surmise that Canon chose to include a low pass filter in the EOS 5Ds while also offering the EOS 5Ds R without¹ a low pass filter because they felt there was enough ...
