Talk:Lens mounts

New layout is live

Ok, the name page layout is live. Feel free to propose further changes and improvements as needed.

SI units trivia

Just for the sake of "correctness" I add spaces between dimensions and the units; as this style guide recommends. But it's probably hopeless to root out every use of "35mm" in the wiki and I don't plan to try!--Vox 12:25, 18 September 2011 (PDT)

Interesting, I'll try to watch that on new data I enter. I can see doing for things which are measurement but I consider 35mm more of a name or standardized descriptor than a measurement, so I wouldn't worry about that one either.

Another minor "style guide" point is that I only use initial capital letters for proper names (e.g. camera brands and models) in page titles and subheads. This is consistent with Wikipedia's guidelines and article titles . I haven't been actively changing existing page titles in Camera-wiki but I often re-do subheads when I come across them. There are a few exceptions when a subhead has been used elsewhere as a wiki-link, like [[Lens#Lens_Speed]]. Anyway, when it's time to merge your work here into Lens mounts, the old page probably has the preferable title.--Vox 15:27, 18 September 2011 (PDT)

Preferable because of the Upper/lower case or because it's singular? I thought "lens mounts" worked better because the page is about lots of mounts. I'm fine with lower case. I'll try not to upper case page names in the future. (hmmm.. though with the Vivitar lens pages, I'm try to make the title reflect the exact lens name as much as possible and occasional words have weird case stuff like "AUTO" insead of "Auto" or "auto" - I guess that's almost like a proper name)

Plural doesn't bother me, but I believe the idea is that when someone wants to wiki-link "lens mount" from other articles it's more likely they'll be writing in the singular. Anyway as long as there's a redirect it's not a big issue.--Vox 08:11, 19 September 2011 (PDT)

New page layout proposal

I'm proposing this as a replacement for camera-wiki's current lens mount page. The goal of this new page is to present a sortable table that includes the most useful information about each mount type in an easy to find way.
Steevithak 16:24, 16 September 2011 (PDT)

Proposed additional columns:

• coverage area (e.g. 24x36mm for 35mm SLR cameras)
• coverage diameter (e.g. 43.3mm for 35mm SLR cameras)
• throat diameter (e.g. 42mm for most lenses designed for 35mm SLR cameras)

Throat diameter is physical size of the circular opening on the camera. Coverage diameter is a theoretical circle of coverage on the output side of the lens. Coverage area is the rectangular size of the area actually intended to be covered by the camera system the lens was designed for.

Request for comment

This page seems very confusing. The title suggests it will be a list of lens mounts but it also brings in unrelated information like film vs digital, digital sensor types, large format camera vs small format. It leaves out the minimal information about the lens mount variations that would make the list useful like, say, flange distance. This makes it difficult to a) know where on the page to look to find a particular mount type and b) know where on the page add a new mount type. For example, I was going to add some of the T mounts (T2, T-4, etc) but they can occur on both digital and film cameras as well as on other types of equipment. I'd suggest a major reorganization of the page into a sortable table with fields like "mount name", "camera type", "flange distance", "mechanical description" (e.g. M39x26tpi, breech lock, bayonet, etc), and then maybe a comment field. Thoughts, comments?

"times" symbols

I was politely asked somewhere -- thought here, but it seems not -- to revert my previous change from "x" (small "X") to "×" ("times"). As nobody spoke up for the "×" ("times"), I've reverted. -- Hoarier 22:40, 7 January 2012 (PST)

Wrong throat diameters

There are a lot of incorrect data in the "throat diameter" column. For example, the Pentax-K mount is said to have diameter of 42mm. That is totally wrong. 42mm is the diameter of the m42 screw mount and an entire m42-PK adapter fits within the PK mount. There are a few other mounts marked as 42mm and I found them to be also wrong. Those include but are not limited to: Y/C, Canon EF, Canon FD, Nikon F, Exakta/Topcon, Olympus OM. The listed are those I have on hand and can take a measurement. If the correct data is not available it is better to leave it empty.

If the correct data is not available it is better to leave it empty. - You come across as a little pissed-off; I don't suppose anybody deliberately entered incorrect values. If you have got as far as measuring some lens mounts and have better numbers, why not edit them into the page? --Dustin McAmera (talk) 14:54, 20 January 2014 (PST)

Sorry if anyone feels being pissed off; didn't mean to do that. I have been working on gathering data and supportive documentations on some lens mount data, and will update the page when I have enough confidence on the data I have. The site is regarded as more authoritative than an arbitrary web blog so I usually pay extra attention on the materials I put here. --xjx1998 9:54, Jan. 27, 2014 (PST)
