I'd completely forgotten I had a different file that includes both the 600 & 800 in a Yashica DX lens brochure. The details are sparse and it's only the side views, but it may be helpful in some context

Thanks very much. I've tried to contact the owner of the 60CM lens, but it's a defunct email.

Just added the missing AF 28-70 Power Zoom and added the optical formulae for the AF 24mm, AF 28mm & 75-300 f4-5.6 Macro.

Hi all,
2 questions about dx in 2.0,
i see in the list thta there are 2 versions, 1 with 6/5 and the (possibly the later..) 2nd one with 6/4.
Can someone copy/pasta some pics to clear the outer visual / identifying difference please ?
and - is 6/5 somehow relevant to the penta pre-set model ?
I would not be surprised ...
Thanx
Cheers

Hello xkaesThank you for spotting this; I'm certain it was entirely my error and it is now corrected in the draft list. It also reminded me that the optical formula for the very rare ML 20mm f3.3 was missing and has today been verified and added.

Another question that I should have asked. I notice that at least some of the Yashica 20/21mm lenses were not retro-focus optics and would need cameras with mirror lock up. What Yashica cameras offered mirror lock-up?

What Yashica cameras offered mirror lock-up? Mirror lockup, in at least the M42 bodies, was available on the TL Electro X, TL Electro X ITS, and the TL Super. There might be others too, but most would have been 'simpler' model cameras and had the push-down DoF actuator in the same spot as the mirror lever on those bodies. The DoF lever was moved to the opposite side of the lens mounting block so they didn't lose that functionality when adding the lockup feature.

If this lens list in in a spreadsheet of some sort, I'd be happy to add a "FILTER SIZE" column and fill in what I have -- which is a lot. People will find it very helpful, and it will only take me a few minutes.

People will find it very helpful, and it will only take me a few minutes. Most of the draft list lenses are already in a spreadsheet, and they can be modified by anyone who can import or open them. They're in this topic, and in Office and Open Document formats... yashica.boards.net/thread/958/lens-data-downloadsThere might be a couple of lenses missing that were recently included in the original thread in this topic, as maintained by biggles3 , but not many.

I've downloaded the YASHICA spreadsheets -- *.odx & *.xlsx -- and added the filter sizes that I have in a new column. I noticed a couple of differences in the file that I downloaded and the table at the top of this thread. Most notable, the list at the top of this thread shows a 35-105mm DSB, but the file I downloaded, does not. I think it is just an error is the listing of another 35-105mm -- but I added a new line for the DSB version -- just in case. I don't know the process of uploading these files to the FORUM, but I don't want to over-write what is already there -- even if I could. Here are the updated *.odx & *.xlsx files in web-friendly lower-case. www.subclub.org/yashica_draft-lens-list.odswww.subclub.org/yashica_draft-lens-list.xlsxI hope this helps.

Thank you for the update and changes. :) The file repository is able to do versioning, so this will be a chance to see if it will do what it's supposed to do. I'll update when it's in place.
