UV filtres and Mamiya lenses. I tried to spot the difference

Alan Edward Klein · Dec 5, 2019

I spent most of my life worrying about things that never happened, trying to protect myself from the pitfalls of living. What a waste of time.

Of course, now that I;ve said it, tomorrow I'll probably go out and drop my lens and break it.

And a filter that has a fingerprint on it is a lot easier to deal with than a lens with a fingerprint on it.

For me cleaning a lens is as easy as cleaning a filter.

Same here, and I never happened to leave a fingerprint on the front lens of any of the cameras that I have ever used.

Most of all I would never - by any means - add two more reflective and refractive surfaces that will always degrade the images of a top-quality lens, just in order to prevent the remote case that I might perhaps touch the lens with a finger.

Ah, but you probably have two fully dexterous hands available to handle your cameras and filters.
I don't.

The best way to keep your fingers off the lens , leave it in the bag .
^^ Would you mind showing us an example of a filter degraded image .

My standard argument is that we use lenses with up to 30 reflective surfaces and why then bother about 2 additional?
BUT there also is something as filter-induced ghosting. Solution would be filters in the form of o-diopter menusus. However I do not remember either brought up by others here, and the critique on filters is typically vague optic-wise.

I always did, and I would be mostly suprised if you didn't. Although I understand that most people are uninterested to what I write here, and even less memorize what I write, I believe I have repeated so many times how I appreciate makes like Mamiya that had an expertise in designing sharp and contrasty lenses with very few elements/groups, that I might have reached stalker status. The only lenses that except the "less is more" strict rule in my setups are retrofocus wideangles, as there's nothing to do with them.
