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 ...

Megapixels: Do they matter that much?

How good is the weatherproofing on a Canon 5D Mk IV

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 ...

Megapixels: Do they matter that much?

Megapixels In my opinion is not that significant, except in the case you really need them of course, but the jump needs to be double, for example from 12 to 24. In my opinion, the best reason to ...

Is the Canon 5D noise at low light better than the Rebel T3i/4i/5i/6i models?

Why does 5DSR have a low pass filter?

Artifacts such as a moiré (more-ay) are repeating maze-like patterns, with or without color. Artifacts are a fact of life because the digital camera uses an array of primary colors to fracture the ...
