I did not presuppose anything. If you READ my remarks I wrote that vignetting MAY result and that would depend on the particular filter thickness and the nature of the lens mount. I did not say it WILL happen, but it very well MAY occur.

I have experienced this issue in the past. I am simply relating my experience, not quoting endless reviews. I did not insist on anything and just put the informal to be considered.

That is simply my opinion, and obviously, you have yours. The OP or anyone else reading on can consider everyone's opinion and make up their own mind.

I am aware of the date.

Chill out and have a nice holiday weekend!

Don't.

Avoid slim filters at all costs.
Very few if any lenses today require them.
Stick with regular filters and all will be well.

Indeed. I'm always amused to hear reports of a filter having "saved a lens" by shattering when the lens was dropped or bumped. The front element of a lens is vastly more shatter (and scratch) resistant than any filter. Think about it, folks.

I would call B&H this week and ask them. I believe they would have one. Closed today and maybe tomorrow as it's a major Jewish holiday.

I have had the front element saved by a clear filter that broke.
Yes it breaks easier, the ring bends etc.
Like the crumple zone on a car.
The impact is reduced and not transferred directly to the lens always.
Yes filters do work.

I am not even going to discuss the merits of protective filters one way or another. But what sort of lens uses a 43mm filter. The smaller standard lenses are or were 49mm and 52mm. 43mm is the size of an enlarger lens. It will be hard to even find that size let alone thin style. I recently had a hard time finding any selection for a 86mm filter for a zoom lens. I finally found a used M+W Schneider UV for a reasonable price from KEH. 52mm to 76mm are common. RF is what? Not "radio frequency" obviously. I know what ST-CP is. Some brand specific thing right?

You are making an unsupportable assumption. From our own Steve Perry: https://youtu.be/P0CLPTd6Bds

This filter or no filter discussion takes place like clockwork every few weeks here on UHH. I always put a UV or similar filter on every lens I purchase to protect the front of the lens. I have never noticed any degradation of my photos due to the filter. When it comes to cleaning the front of the lens I would prefer to clean the filter numerous times rather than clean the lens itself. I often see on ebay where occasionally some lenses are described as having cleaning marks on the front of the lens. Golly, I can't imagine where those cleaning marks might come from except for over cleaning the lens glass. I prefer to have any cleaning marks on the filter and not the lens IF that is going to happen.

I appreciate your photo because it would appear that IF on some lenses the filter might cause vignetting then would not the lens hood also cause some type of vignetting. If ultra wide lenses can pick up the edges of a filter to cause vignetting then why don't those very same lenses pick up their own lens hood in the photo.

In the end, for all of us this filter/no filter becomes a personal decision. We either like it or not. I never understand people jumping on the bandwagon to convince others of their decision to never use a filter to protect the lens. I made my choice back in the 1960's to keep a filter on the lens. Nothing since then has ever convinced me differently.

Did you folks actually read the OP’s question? He asked for a recommendation for a slim filter that would allow a lens cap to remain attached. Of course, the question prompted the usual (and totally useless) slew of proselytizing about the merits of “protection filter v. no filter”. I cannot understand why the zealots on both sides continue to try to browbeat people into accepting their point of view. Get over it. I doubt there is a photographer on this planet that isn’t familiar with the ad nauseum argument, yet each side just continues to bombard the other with “facts” and cites supporting their side.

The only answers so far that are useful to the OP are those that point out that one might be able to use a normal sized filter rather than a slim one and avoid his lens cap issue.. The rest of them are just people trying to bludgeon the other side into submission. Again!

I use B + W thin MRC filters too and recommend them.

I also use a replacement lens cap sized to fit over the lens or the lens with the hood mounted in reverse. Something like this (buy the one sized for your particular lens):

You are right! There is no wrong with differences of opinion, however, there is a lot wrong with rudeness, arrogance and just plain nasty behaviour.

I should know better than to participate in these redundant conversations. When dealing with grumpy and arrogant people, it is impossible to inject any kind of compromise whereby there, are pros, cons and workarounds in many techniques and concepts in photography.

Why is it so difficult to be polite? Why can't some folks say "I have a different opinion than yours or I disagree" instead of implying that "you are stupid, full of crap, and senile". That is the vibe I get for some members of this group.

Chiming in on these questions about "lens caps" is a waste of time and I am beginning to believe that participating in the entire forum is definitely an unmitigated waste of time.

My goodness! If the clip-on spring-loaded lens cap won't stay on, get one of these rubber ones that will fit over just about anything and use any filter you please.

Again you are right! I did misread the OP's question. Weh he mentioned a thin filter, I assumed he need one to avoid vignetting on his new wide-angle lens. So, I provided him with a link to a website with hundreds of filters of every description and a handy anti-vignetting guide.
