BjarniM Posted June 5, 2018 Share #1 Posted June 5, 2018 (edited) Advertisement (gone after registration) Is it a disgrace against the 50mm APO and waste of money to put a protection filter in front of the lens? What's your opinion about using a protection filter given the sublime quality optics in the lens? Edited June 5, 2018 by BjarniM Link to post Share on other sites More sharing options...

Mute-on Posted June 5, 2018 Share #2 Posted June 5, 2018 I’d rather pay for a new filter than a new front element or lens. Use a filter. B + W or Heliopan clear. The waste would be what it could cost you if you don’t use one ... 4 Link to post Share on other sites More sharing options...
strohscw Posted June 5, 2018 Share #3 Posted June 5, 2018 (edited) I never use filters as protection for my lenses, I pay a lot of money to get the best lenses, so I don´t want to reduce the quality by a filter if not necessary. As protection I have always my lens shade mounted which is cheaper to replace if needed. My 2c Edited June 5, 2018 by strohscw 3 Link to post Share on other sites More sharing options...
pgk Posted June 5, 2018 Share #4 Posted June 5, 2018 (edited) If you use a good filter (Leica, B&W, etc.) I am absolutely certain that you will not notice any difference in image quality, sublime or otherwise . Edited June 5, 2018 by pgk 9 Link to post Share on other sites More sharing options...
MarkP Posted June 5, 2018 Share #5 Posted June 5, 2018 (edited) I use glass prophylaxis (for front element and lens barrel thread), except in certain situations at night where reflections may cause problems. I have not seen image degradation with clean high quality filters Edited June 5, 2018 by MarkP Link to post Share on other sites More sharing options...
ktmrider2 Posted June 5, 2018 Share #6 Posted June 5, 2018 (edited) I have UV filters on all my lenses. Rock climbing years ago and I look down and see a star pattern on my 24f2.8 mounted on my Nikon F taught me a hard lesson but even then it was the filter not the lens which was shattered. Wide angle hoods don't offer much protection. However, the question seems to me to be if a $8000 50 Summicron that has a claim to fame of ultimate sharpness would actually lose visual acuity with a UV filter in front of the lens. Of course, if I spent $8000 on a 50 APO, I might want a bit of protection and be willing to sacrifice just a bit of acuity to protect my investment. But if that is the case, why not just buy the straight 50 Summicron? Interesting question is it not? Edited June 5, 2018 by ktmrider2 3 Link to post Share on other sites More sharing options...
Ecar Posted June 5, 2018 Share #7 Posted June 5, 2018 Advertisement (gone after registration) I'm not a big fan of the 50 APO sliding hood for protection, whether against light or impact. Depending on circumstances I use a B+W clear filter and/or a vented screw-in hood. As far as I can tell, the filter has no noticeable impact on IQ. The hood, on the other hand, blocks more of the viewfinder. 1 Link to post Share on other sites More sharing options...
Exodies Posted June 5, 2018 Share #8 Posted June 5, 2018 Learn from experience. If you have ever damaged a filter or front element then use a filter. If not, don’t. 3 Link to post Share on other sites More sharing options...
mls1483 Posted June 5, 2018 Share #9 Posted June 5, 2018 With a good filter (e.g. B&W) you will not sacrifice image quality - at least not to a noticable extent. I always use filters. 2 Link to post Share on other sites More sharing options...
Guest Posted June 5, 2018 Share #10 Posted June 5, 2018 Learn from experience. If you have ever damaged a filter or front element then use a filter. If not, don’t. Full consent, even if my personal deadline is somewhat lower: When I remove dirt and smudges after photo excursions in sandy, dusty, drizzly or dirty industrial areas with coal dust, I am glad to have to clean only the front screen of a filter and not the front lens of a valuable lens. Nothing prevents me from unscrewing the filter in clean areas and safe situations when, for example, extreme backlighting or headlight could cause additional reflections.

microview Posted June 5, 2018 Share #12 Posted June 5, 2018 And with some fabrics, for example, the 39mm UViR filter brings positive gains to IQ. Link to post Share on other sites More sharing options...
lct Posted June 5, 2018 Share #13 Posted June 5, 2018 Reflections cannot be avoided when the glass surfaces of the filter come into contact with air so i don't use filters generaly but i always carry a couple of them in my bag for sake of precaution.

Jeffry Abt Posted June 5, 2018 Share #18 Posted June 5, 2018 Yes! Wouldn’t it be wonderful to open your camera bag and find your APO 50mm and your 35mm Cron have reproduced. What will the children turn out to be? 2 Link to post Share on other sites More sharing options...

frame-it Posted June 5, 2018 Share #20 Posted June 5, 2018 and what sizes are the prints in order to differentiate between IQ with/without the UV filter ?
