I have the 55 SSC Aspherical and can honestly say I've never seen the onion rings and I typically use it wide open to f2. That's not saying they're not there just questioning how much it matters. ...
-
There are lots of sharp lenses out there. TBH, I think sharpness is a little over rated although there certainly are times when it is probably the main factor, maybe for landscapes, architecture ...
-
Indeed, I have one. It's a very good lens considering its negligible cost.
-
I'd be interested to know what this is too. I suppose if it wipes away then it's just vapor deposit from internal oil, if it doesn't then it's possibly separation. I don't know if fungus can ...
-
It's an interesting lens it's just a shame that they all seem to be adversely affecting by separation. It's a nice taking lens. The floating element is intended to optimise correction at close ...

I've had several custom adapters made by RAF camera but this tool is quite useful, as is the page for measuring threads. Thanks.

Sorry about that. If you click on the link in my post above then it certainly doesn't work, as you said, but copy/pasting the link into a browser seems to work fine.

There are a few 'transmittance vs wavelength' charts from Schneider below (from http://photocornucopia.com/1061.html ) http://photocornucopia.com/archive/92/37275_Componon_4-0_28.pdf http://photoco ...

No problem, I think I stopped updating the 'adapter' type information many years ago, so certainly worth updating.
-
Whilst I agree with most of your comments I think the above is essentially misleading. It's true that '...many enlarger lenses are not designed for visible light...' but this is mainly true of ...
-
Nice job on the web page/blog. You write very well and I would agree with probably everything you've written about ELs. Not sure if you mentioned it, you probably have, but ELs are great as ...
-
I don;t know what the filters are that you are referring, they sound like they are quite light, to but unless they are quite intense then they are quite unlikely to have a significant effect with ...

I've been using the Mirex T/S adapter (EF mount to fit Mamiya M645 lenses) for over a dozen years. I find it OK for some purposes but I think a dedicated TS lens will generally perform better, ...
-
Looks like separation. I have a few lenses with separation and their image quality is certainly affected. I would NEVER buy a lens with separation given a choice. It can be extremely expensive to ...
-
I doubt there is any such thing as a 'bad' macro (internal faults, haze etc aside), so I doubt you would go too far wrong with any of the lenses you listed. For value I don;t think you can go past ...
-
I highly recommend the 57 f1.2 as a 'pictorial' lens when used wide open. It's not sharp like modern lenses but instead has ample sharpness with lots of the right aberrations for people and ...
-
The environment rather than the lens itself is the major contributor to fungus. A survey such as this can also be skewed if certain brands are more popular in damp or humid climates. I consider ...
-
Ditto. Can't fit AR to EF without all kinds of optics inbetween to account for the difference in flange focal length. Don't even know if such an adapter exists. That's why the AR lenses were ...
-
I'm certain that 1M (the internet rumor more commonly suggests 1.1M) copies are no better than any of the late copies with serial numbers in the 8 or 900000. I've had several, including the 1M and ...
-
The serial number on that lens is quite a late one so it is in fact a very good version of that Zuiko lens, as long as it's clean and free of fungus/haze etc.. I have quite a few fast 50's and ...
