Go to min. 2:30 to see the Cosina fab and how they make their (handmade) lenses.
While we are still waiting to get our hands on the upcoming new Sony NEX lenses (like the soon coming Zeiss 24mm f/1.7) there is also “hope” coming from third party lens makers. According to our very first and new “Cosina source” there will be a new all manual and ultra fast Voigtländer lens coming by end of the year 2011. Their current only lens for mirrorless cameras is the [shoplink 6619 ebay]Nokton 25mm for m43 (Click here to see it on eBay)[/shoplink]. The source is new so please take the rumor with a grain of salt. But It might not be casual that at the end of the video on to the Cosina Designer talks about the NEX system… 🙂
And now the big question for you:

P.S.: What you might don’t know is that Cosina also produces many of the current manual Zeiss lenses.
P.P.S: A while ago there was a [shoplink 5973 ebay]Nokton 25mm with NEX adapter on eBay[/shoplink].

I didn’t know they were still made by hand. Awesome!
Yes, i just watched at m43 rumor site. they got think in mind for e mount movie lens. awesome!
But i am confuse, how are ultra fast lens is in manual? then will depend how fast of our hand/finger precisely 😀
“fast lenses” refers to lenses with large apertures. f0.95 gets a lot of light, so you can use a fast exposure.
There’s a very good explanation in Wikipedia: http://en.wikipedia.org/wiki/Lens_speed
FWIW, lenses from various manufacturers are hand assembled, but, like with the 25mm .95, the parts themselves are usually machine made.
What is it with these people/manufacturers and manual lenses… You can barely see sh*t on these LCDs…
Maybe Sony and other/all should develop a software focusing screen/prism/katzeye auto zoom simulation to make them half useful and accurate with todays high MP sensors and pixel peeping critics!
I use both the focus magnification and one of these in various combinations: http://forums.dpreview.com/forums/readflat.asp?forum=1042&thread=38124924
Manual focusing is pretty easy, IMO. In fact, I prefer it.
Ditto. Definitely having a lot easier time doing manual on the livescreen with the focus mag, and this is coming from a guy who uses a DSLR with a Katzeye.
It all depends on a camera you use.
Modern entry level DSLRs have very small focusing screens, but if you’ll try for example the Alpha 900 than the manual focusing will be super-easy. 🙂
That’s why there is there focus assist (little green dot) to help with that.
This could be exactly what i’ve been waiting for. The problem–is that Voigtlander’s .95 for m4.3 is unimpressive, at least in my opinion.
I hope this effort is better, else I’ll simply opt for the Voigtlander 35mm 1.2 II as originally planned.
if its gonna be in the same price range with the 25/0.95, then im better off with the 35/1.2 or 50/1.1, which i can still use on my m system
I’d say a price similar to the 25/0.95 is almost a certainty–if not more expensive.
Video on how photographic lenses are made.

I think it would be an interesting lens to try out and play with to say the least.
the lenses are hand assembled not hand crafted. most lenses are still hand assembled to some extent, and the more expensive lenses higher quality and especially longer focal length lenses (eg 300mmG or canon’s 500mmL)have more hands on and stringent assembly process.
and WOW, not to be nit-picky but @1:40 when the narrator is talking about DoF, he says wider aperture increases DoF, and smaller aperture decreases DoF (watched it 5x to make sure i wasnt imagining things). I thought it was the other way around. only way that makes sense to me is if the person who wrote the script isn’t aware that f-stops are fractions, making a f/[insert large number] a smaller opening. or am i mistaken and have a wrong understanding of aperture and DoF?
Video was made by JBC, for general audiences, not photo enthusiasts. The average person thinks that f0.95 is smaller than f8.0, just like 0.95 lbs is smaller than 8.0 lbs 🙂
So the writer knew what s/he was doing. A thinly disguised commercial posing as news.
I can believe that any quality lens would be made, or assembled, outside the clean room environment and without the regulation face masks, hair nets and other paraphernalia.
