The LEICA DG SUMMILUX 15mm / F1.7 ASPH. is an excellent 15mm single focal length lens of F1.7 clearing LEICA’s stringent standard. It also features sophisticated exterior that matches the stylish design of the world’s smallest LUMIX GM digital single lens mirrorless (DSLM) camera.

In addition to “LEICA DG SUMMILUX 25mm / F1.4 ASPH.” and “LEICA DG MACRO-ELMARIT 45mm / F2.8 ASPH. / MEGA O.I.S.” which are already released to the market, Panasonic has also announced product commercialization of LEICA DG NOCTICRON 42.5mm / F1.2 to enhance the lineup of LEICA digital interchangeable lens, attracting professional photographers worldwide.

In the meanwhile, Panasonic is further expanding the range of LUMIX G digital interchangeable lens with the development of new LUMIX G VARIO telephoto zoom lens of 35-100mm in stylish, compact design that also matches the LUMIX GM camera.

http://www.ebay.com/sch/Lenses-/3323/i.html?_stpos=&_fcid=168&gbr=1&_localstpos=&_nkw=panasonic+25mm+lens&_clu=2

I sold my 20mm and gots me one of these babies a few days back (first batch in UK) for a really good price (under £400 early display copy no box or pouch but got the hood!).
Also owning a Voigtlander 25mm 0.95 & Voigt 35mm f1.4 Id thought I would share my personal thoughts in comparison.
Well to start...The lens is good....damn good.
Pros
Sharp even at F1.4 Detail and rendition of colour is beautiful.
AF is very fast and accurate on my GH2 not so fast on my GF1...but still faster than the 20mm f1.7
Very controlled image...by this I mean it has very little CA and no flares

But heres the Cons
Price...I was lucky to get this cheap but general UK retail is near £560!...that im sorry is ludicrous...It has astounding optics and yeah okay f1.4 with fast accurate AF is probably why but no!
Why? Build...Plastic! (albeit harder plastic than other Panny lenses)
The voigts FEELS expensive (heck even my Super Tak 50mm f1.4 feels more expensive) you know its crafted...but the Leica? Just off the mass produced factory line...for that price we deserve SOLID BUILD!

Lacks the ability for creativity because of its very controlled image...by this I mean its lacking character...much like the 20mm f1.7.
You can have more creative image with the Voigt.
Focus ring for MF...I just dont like it...theres no give...its just silly smooth so hard to be pinpoint accurate. The Voigt has very nice dampened focus ring and can be accurate even at f0.95

I would say if it was cheaper then get one as it is really superb...but as the price is very close to the voigt 25mm f0.95 I would say get that if you can live without the AF as it gives more stops of light and feels like you bought something that justifies the cost.
Is it better than the 20mm?....absolutely without question BUT if you have the 20mm and cant afford the Leica...dont lose sleep over it.

Anyway I leave this with a quick snapshot of my little girl taken with the Leica & GF1 (both at f1.4 in jpg right out of camera no post)...I was amazed by the detail even on a ye olde GF1 so can give you a idea of the quality.

I understand this adapter gives an extra stop of light and allows me to use 35mm glass. My question is, how do I determine what the f-stop will be and focal length of a full frame lens once equipped with the lens turbo? For example, if I attach a Canon 50mm f1.4, would the focal length still be 50mm and the f-stop still 1.4 - or would it be less?

I appreciate your help,

Most wanted ANAMORPHIC lens http://www.personal-view.com/talks/discussion/4466/most-wanted-anamorphic-lens Tue, 04 Sep 2012 15:35:25 -0600 slrmagic 4466@/talks/discussions Dear All,

We have received 4 email requests from members of this forum on the possibility of designing an Anamorphic lens. We had this thought for the past year and did a lot of research. There is one common request which is to have horizontal flares. The others requests did not have any common grounds. We came up with an idea for a 25mm f/3.2 1.35x or 35mm f/3.2 1.35x Anamorphic lens for micro four thirds. Shooting at 16:9 would give a 2.40:1 anamorphic output. Just before we decided to go ahead with the project we had a second thought. 2 Years ago we asked openly on dpreview.com forum for what photographers wanted and the general consensus was our SLR Magic HyperPrime 12mm T1.6 lens.

http://forums.dpreview.com/forums/read.asp?forum=1041&message=36104678

It did not fulfill the needs and wants of everyone but we made what most people agreed on by means of a discussion. It ended up being a popular lens that we still are having problems meeting demand and we think it had a big part to do with asking photographers. If we did not ask around we probably made a 12mm f/2.8 lens. As it turned out quite well last time we want to make our next lens an open discussion again.

Here are some of the possible options we received and please feel free to throw in extra ideas. I hope people experienced with shooting in Anamorphic can also throw in ideas.

Anamorphic Adapter (1.33x, 1.5x, 1.75x, 2x) Dedicated mFT Anamorphic adapter for reasonable size Anamorphic adapter compatible with FF lenses 50mm f/2.8 Anamorphic lens (FF, APS-C, or mFT) Expected MSRP (Sad fact but it as direct correlation to IQ)

Kind rgds., SLR Magic Team

P.S. We will be at Photokina 2012 and would like to welcome any cinematographers with Anamorphic lens ideas to drop by our booth for idea exchange! We will be in Hall 3.1 B059

9mm F8 body cap Olympus. Maybe cheapest m43 fisheye. http://www.personal-view.com/talks/discussion/9950/9mm-f8-body-cap-olympus.-maybe-cheapest-m43-fisheye. Sun, 23 Mar 2014 11:11:40 -0600 ahbleza 9950@/talks/discussions image

Olympus' tactic of playing down the optical performance of this lens need not be necessary. Even though this lens only costs £90 and is little more than a body cap with some glass in it, it is still capable of delivering decent quality images. Those who fancy experimenting with the fisheye look but don't relish the thought of forking out proper fisheye money, this lens is ideal.

image

Overall, this lens is fun to use, thanks to its compact size and fuss-free operation.

Finally comes the first alternative to voigtlander 17.5mm! And to think that the 17mm could also be better in terms of focal length: in fact the crop in 16:9 mode should be a bit more of 2x, is not it? So to get even closer to the equivalent 35mm, it's better than 17.5 (just to make a speech of fanaticism, but there is!) So: what expectations we can feed? The build quality does not come close to voigtlander perhaps, but in terms of image quality, now we should be very close, is not it? Also the price will certainly be lower, you know if you can buy from a third party and take advantage of a street price lower? Let's keep up to date

Hidden gems among lenses http://www.personal-view.com/talks/discussion/80/hidden-gems-among-lenses Thu, 12 May 2011 00:39:39 -0600 Vitaliy_Kiselev 80@/talks/discussions
First one - Vivitar 28-200mm F3.5-5.3

1) Buy only original 28-200mm as in picture below. Tokina is absolutely different lens with different optical formula (look at crop from Vivitar box, Tokina have fewer elements).
2) For Pentax, lens could come either in PK/A or PK A/R mounts. In former you must remoive Ricoh pin. On both you must use file to remove excessive lever protection.
3) Closed down, lens is PP friend. Good wide open, but as on many old lenses have some abberations. Contrast is lower due to many glass surfaces and not top-notch coatings. Abberations are almost absent if close down (see below).
4) Corners are controlled quite well.

The flange distance is correct because i have a md-m43 dumb adaptor and the total flange distance is the same. My md lenses work fine so after getting the RJ speedbooster .71x I then got a dumb md-eos adapter ring thinking it would work fine and nada.. lens is focusing past the sensor?
