So here's a sample of my attempt at a slightly methodical testing of the effects of my hoya filter v.s. no filter. I wanted to see how much image quality I'd lose by using one (the reason I want a filter is to protect the lens). I couldn't find any other comparisons available so this might help anyone else thinking of buying one and wondering...
This is a plain old "Hoya HMC" clear filter, costed me about $20 (CAD) new off ebay ($10 for the lens, $10 for shipping).
Here's 4 pictures of some lines I drew and a bar code from a receipt lying around. 2 were taken with out a filter, and 2 were taken with the filter. The results of which are which are in the photo comments, but have a look at the picture first and see if you can tell which is which. It's uploaded as a PNG, so right click on the picture, download it, pixel peep it or what ever you want.
I'd be interested if anyone knows of a better way to easily and reproducibly test this. Personally, from a few pictures I've taken, I can't tell the difference with or without the lens filter on. Anyone else? comments?
To clarify, these are 100% crops, they are 1:1 pixel, not scaled down images.
