@Jim: Isn't QRB supposed to be QBM (meaning Quick Bayonet Mount). Rollei QBM is the ubiquitous name for this camera/lens mount, AFAIK.

Hi Benjamin. A quick check on you-know-where suggests you're quite right. I recall going through this a while ago (QRB vs QBM). Maybe I ended up with the wrong conclusion (not like that hasn't happened before). Let me check some stuff when I get home from Bulgaria, on Friday. If I can't find anything solid in favour of QRB, I'll change it here and in Lens$db. Thanks for noticing.

I've been traveling and haven't had much time the past few days to update the top post, but I will try to incorporate some of the suggestions into it by this evening.

So far as the direction that the Alt FAQ might eventually go as it accumulates additional information: one could imagine presenting alt-related stuff on a new website, or perhaps even an Alt Gear/Lenses Wiki. However, I think that there are some unique attributes to the discussion forum approach that could work very well for this type of material. Considering the possibilities for how to organize alt lens information:

Michael,
As soon as I saw your post I thought it was a great idea and you did a great job! As you wrote, local FAQs are great but not very dynamic as additions are not very easily done. This is overwhelming with all the ideas / suggestions but we could work on a system to ease the pain.
Any suggestions on a FAQ system is appreciated. An idea is to use something like the forum FAQ: http://www.fredmiranda.com/forum/faqforum.php - except that it could be edited/updated by selected members.

I would be happy to implement something that could be used and maintained by the community. I'm all ears.
Best,
Fred

Hi Fred, I'm glad you like the FAQ idea. I think the simplest and easiest way to add details and grow the FAQ on specific sub-topics is just to harness the already existing thread/discussion system (having people post "articles" on specific alt-lens topics as a new thread, followed by open discussion and contributions from the community at large; the resulting thread would then be indexed in the main FAQ thread). We already know how to create great informative discussions here . The one place that might benefit from a more complex editing scheme is the top FAQ sticky post; right now I'm the only one who can edit it (short of administrator intervention), but it might be useful to allow a select slightly wider group than just me to edit that one post.

There's lots more edits/improvements I intend to do as I get time (several good suggestions in this thread that I haven't had time to process); for now, I've just added a quick section on adapters with glass elements and "macro" adapters (a question that comes up fairly regularly, as in a post today).

You're right. I fixed the list above and the next version of Lens$db.doc is fixed too. Thanks.

Focus ring and aperture ring directions

A recent question on a different thread prompted me to do this quick study on the variation of focus ring and aperture ring 'directions' for a variety of different lens brands/mounts. Here's what I have on hand.

Infinity on the right, widest aperture on the left

. Contax Carl Zeiss
. Leica-R
. Mamiya M645
. Voigtlander for LTM

Infinity on the right, widest aperture on the right

. Olympus OM
. Tamron Adaptall 2
. Pentacon (M42)

Infinity on the right, no aperture ring

. Canon EF, EF-S, TS-E
. Tokina AT-X for EOS
. Tamron SP for EOS

Infinity on the left, widest aperture on the right

. Nikon F-mount
. Pentax K-mount
. Voigtlander for Nikon F

In order to avoid any 'left-right ambiguity', I've attached a photo of two lenses with different orientation. The Pentax lens to Starboard* has infinity on the left of the focus ring and widest aperture (1.4) on the right of the aperture ring. The Contax Carl Zeiss lens to the West** has infinity on the right of the focus ring and widest aperture (2,8) on the left of the aperture ring.

* image you're standing on a ship at a location aft of the bow, and you're looking towards the bow, with the lenses between you and the bow.

** imagine that you're standing to the South of the lenses, and you're looking towards the North.

P.S. this reminds me of a "left-eyed right-handed" thread I posted a few years ago.

Pentax M42 is in the same category as Pentax K. Canon FD is in the Contax/Leica/etc. category.
I really prefer the scheme of the latter category, for some reason.


About the FAQ, I think there is something that should perhaps be amended in this sentence: For lenses with much shorter register distances, e.g. Leica M on Canon, you're out of luck --- though you can likely use them on one of the increasingly popular mirrorless "electronic viewfinder interchangeable lens" ("EVIL") smaller format cameras.

Sony NEX is one of the increasingly popular platforms for alt lenses, but it's not an EVIL camera. It has no EVF but only a rear display. This has been called a MIL (mirrorless interchangeable lens) camera by some. I've also seen it with the C for camera included, but I like it better as an adjective, instead of talking about EVILCs and MILCs. We don't write DSLRC either.

Maybe mention something about some Canons needing a small "microswitch" to be flipped in order for chipped adapters to work?

Great idea! Unfortunately, it's not practical.

The moderator's primary responsibility is to keep the discourse civil, legal, and non-commercial. The moderator's secondary responsibility is to remember the moderator's primary responsibility.

Having an integrated and context-sensitive thread would be nice. Ideal, in fact. IMO the only practical way to do this, is to have a devoted Alternatives web site, with all of the support that entails. I've already offered to publish 'this site' on my domain, but have not yet received any offers to perform the many and sundry functions that are required. Frankly, I have the desire, but I don't have the time. I'm confident that many other FM Alt'ers are in a similar position.

The primary value of a thread-based FAQ is that you can always see everything that's ever been posted. Dialog, discussion and commentary rule! In order to effectively use a thread-based FAQ, you need advanced 'search skills'. Of course, the greatest challenge can be to know what to seek, and also to know that what you just found might be modified or refuted by subsequent information.

Mike how about adding a section with example of Samuli's or Luka's resize and sharpen routine for everyone, since a lot of people are wanting to find this.

I agree it's quite valuable info but it doesn't really have anything to do with alt lenses.
