If I missed this my apologies....
Would it be possible to have a post explaining...
...the various chipped adapters available such as the Optix V series vs the 1st generation and any other variations....
...the various alternative focusing screens available from 3rd party manufacturers?

p.4 #2 · Alt Lens FAQ


If I may jump into this thread and be so bold...

1/ In p.2 post #13 jcolwell has a very nice list: may I add that for the Tamron Adaptall CF means Continuous Focusing

2/ Also, the Tamron Adaptall 2 might be mentioned...

3/ Where do I get alt lenses from? Could I request you remove the word "from" ... thank you! This is in post #1

This thread is a really great addition to FM alt lenses... I have happened into 4 MF lenses within the last month, and have been active to learn about and understand what I have. As I have just come upon this thread I will look forward to more information in my little archive...

Something else that I think should be added to the section about adapters is the problem with adapters having a loose fit. This can often be easily fixed, as explained here: http://www.pebbleplace.com/Personal/Contax_db_Adapters_1.html

I think it's invaluable info because some adapters will need adjustment when you buy them, but people not knowing how to do it will just think their adapter is bad.

Hi Cheryle,

Thanks for the comments.

The 'close focus' definition for CF is commonly used for both Vivitar and Voigtlander lenses, although I can't find examples where it's actually written on the lens. According to http://www.adaptall-2.org/'Tamron Lens Nomenclature', the Tamron use of CF is "Continuous Focus". I've modified the definition for CF to be:

"CF crop factor for a digital camera, close focus or continuous focus for a lens"

I'm not sure if this comment is made with respect to my list, where Tamron's Adaptall 2 mount is defined for "A2".

I've updated the pg.2 list with the new definition for CF, as well as including about a dozen new terms, and introducing "=" symbols, to help show where multi-line definitions end and new definitions begin.

Cheers, Jim

here is an example of a vivitar lens with 'close focus' written on the lens:





or did you mean you haven't seen an example of CF written on the lens to mean 'close focus'?

There's also some "CLOSE FOCUSING" versions in the Vivitar lineup.

Yet another missing item in the FAQ: Exposure deviations with stop down metering. Anyone new to adapting manual lenses is bound to run into this issue, at least for Canon cameras.

Mike,

Since there are so many Zeiss C/Y users on this forum, how about adding the link to shirozina's excellent thread from 2008 on infinity focus adjustment? Helpful for anyone using old lenses, especially given the large number of adapters of varying thicknesses. Here's the link:

What about converting some of these pages into a wiki and using the FAQ as a front-end into the wiki?

As you add more content to the single FAQ post, it's going to become difficult to read and sift through the content.

You could utilize group editing as well.

@ontime: Great ideas, but who's going to set it all up?

@pcvrz22g: Your post seems out of place here.

Perhaps I missed this, but I think a list of what lens mounts can fit on which systems. I just switched to Nikon due to my only lens being Nikon mount, and I have no idea what I can fit on Nikon.

I know that OM cannot unless you buy a kit (which I might for some lenses..). M42 mount cannot I just read..
Perhaps I will do some research and put together a list for lazy people like me

I noticed this post by AhamB suggesting that we need some alt lens "sticky" posts to answer common questions. That seems like a good idea to me, but since no one else has posted one yet, here is my attempt at a FAQ outline mainly focused on alt lens usage on DSLRs. Please post your comments/criticisms/suggestions below, and I will attempt to edit/revise this post to incorporate them. Each item in this FAQ could be (and often has been) the topic of a long and complex thread; however, for an introductory FAQ, one needs to balance the merits of brevity
...Show more

Actually that's only part of the reason...The Canon EF mount shares the same short and versatile registration distance as the Sigma SA mount but the EF mount is larger in diameter, allowing a greater range of lenses to be used.
For instance, most Canon EF lenses can be converted to SA mount whilst retaining their AA and AF functions (not their IS function though) but the rear element of the Canon EF 85mm f1.2L is actually larger in diameter than the bore diameter of the SA mount, making it impossible to convert it for use on the SA mount.
However, the older FD-L versions can be converted to SA mount as they have smaller rear elements.
In general though, after the Canon EF mount, the SA mount can take a greater range of lenses than Pentax mount SLR's and DSLR's and even more than the second most popular SLR/DSLR mount out there, the Nikon F mount.
