lens filters

[Tui]

Out of curiosity I took some photos with an R6 and RF 24-105mm f.4L lens. With a cheap Hoya UV filter on, and without, no other variables. I can see hardly any difference when looking at full zoom! Can you tell which is which here? I'm a bit rough with my camera gear so for me it justifies using a filter for protection

Well, all these photos were taken indoor, you hardly have any UV anyway. Try shooting a couple of photos at bright daylight, probably pointing towards the sun.

Great set of comparisons. I was actually thinking about this two days ago. Maybe it seems that, for example, 5142 (compared to 5141) has no filter because it's a little lighter and that might be the case for each of 1st in the sets, but, hmmm, quite close.

Even more that being able to tell if a filter is on or off in a direct comparison, my question is if anyone could even tell if they were only looking at filtered shots?

Like, “Look at that awful picture lacking contrast. Clearly they used a protective filter! Amateurs.” I would say 99% of the time one cannot tell.

The only time I’ve run into a filter issue is direct light. Specifically, birthday candles. There’s a ghost reflection of the candle flame that disappears when I remove the filter. So now if I suspect I’ll be combating flare in any way, I just unscrew the filter. Easy.

The greatest debate since debates were invented. My opinion. While you may be able to prove in on paper if you use a high quality filter the human eye can't tell the difference. Or it would be really hard to tell the difference unless the person points has to point any flaws out. If they have to point them out then what is the difference. I have shot though thick dirty zoo glass with a filter and got surprisingly good results. Never had a single AF issue.

It's a personal thing so I'm not trying to promote either side. I used top of the line B+W filters for years and after many debates I decided to remove them. I guess I decided I was being too paranoid. I still have them around for windy beaches and other inclement weather. If I did get a new lens and did not have one that fit I'm not sure I'd spend the money as they don't give them away. I still hate cleaning the front element and was happier doing that to a filter.

I now only use Canon's own protective filters, more like a permanent lens cap rather than anything else. I used to buy Skylight or UV filters for many of my lenses for that same purpose without thinking of the filtering effects.

I don't see a difference between the two sets of shots, however there are likely situations where there may be a slight difference (direct sunlight into the lens that may cause strange reflections other than the expected flare). FWIW, I have always used filters for front element protection and have never experienced any issues. Of course, my results do not determine or predict what anyone else my experience.

This is from 2008 and with my 50D and 70-200 F4 IS and I know I had a filter on the lens back then. Thick zoo aquarium glass. These where the days before AI and we had to actually edit

Roger at Lensrentals tested a bunch of filters.
It's an interesting read.

Lens hoods are your best protection. But it's funny how many people I've seen over the years out in public with it REVERSED. In that case, just leave it at home!

Yes, I thought of that and did take a series of photos outside first. But I dont have a tripod and it was hard to get the exact situation with the clouds moving across the sun and the camera movement. But even considering the changes and focus and sunlight I couldn’t find any differences. And I noticed afterwards the filter was a bit grubby too!
I was more interested in how a piece of inferior glass would affect the lens performance. Would be interested to see other comparisons.

Not sure what’s going on with the duplication of photos …. I must be uploading them wrong

Yes you’re right for 5142… 5137 filter on, 5138 filter off, 5139 filter off, 5140 filter on, 5141 filter on, 5142 filter off
