Do I need a filter to use my Canon EOS 60Da for daylight photography?


Which filter do I need for the 60Da to use it in normal daytime use? Apparently I need a IR filter.


Could someone please explain exactly which one I need and perhaps a link to a place I can buy one? Thanks! (I'm very new to this)



Answer



Because of the 60Da's modification to increase IR sensitivity for astrophotography, if you plan on using the camera for regular visible-light photography, you probably should get an IR cut filter, otherwise you may experience color shifts when the sensor gathers both visible and non-visible light together (magenta cast with synthetic fabrics, and foliage greens being off are common issues with full-spectrum cameras used without a UV/IR cut filter).


You don't want to get what most people think of as an IR filter (like the Hoya R72). That is an IR-pass filter which blocks visible light and only lets IR through--you're trying to do the opposite: block the IR/UV light. Most IR cut filters will also cut UV, because some cameras don't have IR/UV filters over the sensor (e.g., the Leica M8).



Since UV/IR cut filters aren't cheap, you can get one filter that's the largest size you'll need and then "adapt" it to your other lenses with step-up rings. What size you'll need depends on the lenses you'll be using.

Why is the front element of a telephoto lens larger than a wide angle lens?

A wide angle lens has a wide angle of view, therefore it would make sense that the front of the lens would also be wide. A telephoto lens ha...
