LJ - Eljot: Can someone describe in wich way the lack of live view makes a camera cheaper?

Obviously, it doesn't make anything cheaper. This is a classic example of "defeaturing" something through software.

Wow, "crippleware" from Leica. Who'd have thought we'd see this day.

falconeyes: @Brittany Hillen:
> Sans an adapter

I read "Sans" is archaic and used by foreign speakers more than native speakers. It is French for without. Also in this thread, I see this word causes quite some confusion.

My question: Did you use this word for a reason, came it natural for you, or thinking about it now, would you use 'without' instead?

Are you a native speaker, US or UK?

I ask because I am curious to learn about the language. My native language is German.

@Richard, "Celtic" has absolutely nothing to do with English. You're confusing Celtic with Germanic.

Have a look at a typical Indo-European language tree.
http://andromeda.rutgers.edu/~jlynch/language.html

As far as that uncalled-for and insulting "four-letter, one-syllable words like 'rock,' 'hand', and 'meat.'" comment, Old English was a highly sophisticated language with a lexicon of tens of thousands of words, most of them multi-syllable, with very few borrowed words, and with a growing body of literature, when the Roman Empire started to influence it around 450AD. Even then, that influence was largely limited to the adoption of the Roman alphabet, which was much more suitable to parchment and ink than the runes of Old English.

This doesn't look much like someone talking about rocks and meat in monosyllables, does it?

photomedium: I found the comment section here to be populated by a bunch of idiots with very short term memory. This diatribe about Brittany's use of the word 'sans' is far from a one off case, but is rather the norm. Maybe this is the result of too strict moderation policy or a case of temporary stupidity induced by excessive pixel peeping?!? I don't know. These comments are not clever and are not funny.

> Alas dynaxx, you appear to be the genuine article.

He is a genuine troll. Check out his posting history. His only purpose in this discussion is to cause trouble and prolong the argument. This site would better sans his ilk.

mr.izo: only problem with these classical design range finder lenses (beside af obviously), is their short flange distance. this does helps build smaller footprint lenses and all that, but on the other hand shows problems with aberations, corner sharpness etc, which was proved many times using these lenses on mrl ff cameras. yes, they can have super sharp center sharpness, distinctive micro contrast and all that, but for some serious wide angle work (architecture, landscape, interiors..) i would be careful and check things first..
edit:
i forgot: usually, also min. focus distance is bigger on rf lenses, that can be very limited sometimes.

> min. focus distance is bigger on rf lenses, that can be very limited sometimes

I wouldn't worry. That's not a characteristic of the lenses themselves, it's a characteristic of the Leica M rangefinder system. The rangefinder on an M focuses down to 0.7m. The Nikon mount Voigtlander 20mm focuses down to 0.22mm.

I expect to see these new lenses in longer focusing mounts, too.

SKPhoto12: Why 3 lenses with such close focal length? I don't understand the brand logic. One step back or two forward will cover that focal length. Why not market one lens with 12mm focal length? Provide all the electronics and I think it would sell better than the almost finished product.

> One step back or two forward will cover that focal length.

Ultrawides are most commonly used for architectural or landscape photography. One step back or two forward will do...

absolutely nothing.

I still remember the last words of my mentor, as we were photographing canyons in Arizona.

Zoom with your feeeeeeeeeeeeeeeeeeeeeeeeeeee...

And if you're framing a close subject and want an expansive background (because even ultrawides have uses in people photography) then for the same subject framing, the 10mm will include 2.25x as much background area as the 15mm.

"Such close focal length" indeed.

They're not "close".
* 12mm is 20% longer than 10mm
* 15mm is 25% longer than 12mm

20-25% is "huge" in focal length changes.

Look at some other common focal lengths.
* 58mm is 17% longer than 50mm (both Nikon and Cosina make both 50mm and 58mm lenses)
* 28mm is 17% longer than 24mm (both Nikon and Cosina make both 24mm and 28mm lenses)
* 35mm is 25% longer than 28mm (Nikon, Cosina, Leica, and probably a lot of others all make both 28mm and 35mm lenses)
* 100mm is 17% longer than 85mm, 105mm is 24% longer than 85mm. Nikon, Canon, Sony, Zeiss, and probably a lot more all have an 85mm and either a 100mm or 105mm.

LFPCPH: According to Cosina's English website - the following products are discontinued sept 28, 2015.
SUPER WIDE-HELIAR 15mm F4.5 Asp II
BESSA R2-M and BESSA R3-M and BESSA R4-M cameraes.
VM Micro Four Thirds Adapter
F Micro Four Thirds Adapter
SC E-mount Adapter
15mm View Finder
21/25mm View Finder
21/25mm View Finder M Silver
28mm View Finder M Silver
28mm View Finder M Black
35mm View Finder M Silver
35mm View Finder M Black
40mm View Finder
All from Cosina's M-mount product line. Maybe this is a hint to a Voigtlander digital M-mount camera with no need for view finders.

Or a hint that they're exiting the camera business to focus entirely on lenses.

Ken Sky: I would think the hardest challenge using the 10 mm. (after paying for it) would be keeping your feet or the tripod feet out of the picture :-)

Nope, and nope.

It's nothing like an APS 8mm fisheye, which does see 90 degrees off axis over a substantial portion of the image frame from the corners to the sides. A 10mm rectilinear on FF only sees 65 degrees in the corners and 61 degrees at the sides. You won't see your own elbows.

And even in vertical shots, you'd need 2-3 feet (0.8m) long feet to get them in the picture.

Don't believe me? Take the 8mm APS fisheye and do a full rectilinear wide-angle conversion, which yields a 6.9mm equivalent on FF, and you still won't be seeing elbows or feet or any body part. Those will end up in the parts that are cropped out during the conversion.

Nope.

A 10mm wide on FF on a horizontally framed picture only sees up and down 50 degrees. Assuming you're holding the camera at eye level, your feet would have to be 4-5 feet (about 1.6m) long to get in the picture.

yahoo2u: ....."All three lenses will feature a Sony E-mount for use with full-frame Sony cameras sans an adapter."
.
It is "without an adapter"
.
If you want to throw in french expressions while writing english go to france.

Sans, from the Latin "sine".

First documented English usage 1320. "He schal beo poisond, saun return Of his owne traitour."

I could add a few more Shakespeare references to what Boissez added. That Shakespeare, what a hick. Nowaday, we call him William, but you know back in 1588 all his friends called him "Billy Bob".

RichRMA: Good thing you'll be wearing one of those ridiculous headsets in the privacy of your own home, so no one will laugh at you. The idea of using iPhones and the like, ganged-together as the displays for these things is just pathetic.

Well, sure. Except for the minor detail of it being light enough so that you don't need a ceiling rail system and pantographs to support the 25 pound headsets. And the increased resolution, wider fields of view, and self contained computer systems.

But once you ignore those little (all important and enabling) details, yeah, nothing has changed.

M Lammerse: I think there will be always an artistic 'need' for 'flat' imagery, (digitally) painted or photographed.

As long as you have to do something specific technical to see or enjoy it in an other form, it will not be the future, as an example 3D technology is also not what "they" (the marketeers) expected of it.

3D technology is delivering about $5 billion a year at the movies.

You don't gang the iPhones together. One phone, and something like a Google Cardboard, Zeiss VR One, or Samsung Gear VR.

AlanG: Gee. This sounds like something Paul Buff did more than 20 years ago with their first remote control system. And the Buff Cyber Commander has been around for quite a while too. It meters, lets you control each light individually or in groups, and triggers the units.

Elinchrom has basically lagged the whole rest of the industry for years as far as remote capability and features. My take is that, by proposing their highly limited system as an "industry standard", they will be able to scream "you're not standards compliant" at everyone who has a better system.

They haven't really been "Swiss" for several years.

JJ Rodin: Actually always wondered why several of those Sony Zeiss lens were only just so-so, but yet expensive enough to be better optically.

I even asked if Zeiss designed the lens and Sony manufactured them or exactly what, now we know more.

Zeiss makes some great lens and you PAY for them !!

Do we "know more"?

Does Zeiss say they "designed" anything, even once, in that article?

Ben O Connor: Back in the day; Nokia sealed a deal with Zeiss and it feels like "forever"! Even now Microsoft's windows phones comes with "Zeiss optics".

I think Sony is very jealous even angry about it!

Microsoft/Nokia is approximately 5x more popular than Sony.

http://www.statista.com/statistics/271574/global-market-share-held-by-mobile-phone-manufacturers-since-2009/

Microsoft/Nokia, believe it or not, is about even with Apple in headsets shipped.
