@labalbi Well you have all native mft electric, sharp lenses there. You will notice a change if you try to edit them together. It's just the way it is. The SLR will cut with older glass, Voight and I'm sure others that I don't know about much better than your other glass. I did a resort promo shoot that's up on Vimeo and used the SLR12mm, Rokinon 85mm Cine and for some night stuff, the Pany 20mm. Since the 20mm shots where at night and all cut by themselves, it's not apparent but I can see a difference with the 12mm and 85mm stuff cut together. The Rokinon is much sharper but I wasn't using the 12mm for sharpness. I was using it for flares and it's organic properties.

On the other hand, I might just be too sensitive and most people might not know. My girlfriend never sees the difference in stuff like that and I always ask her to compare shots and she just looks at me like I'm a dumbass! :)

@tenjin You're already mixing lenses so who cares. If you're going to use the Voight and one of the electric, overly sharp mft lenses, it doesn't matter. If you are going to be shooting people, you will see the difference in the skin tones for sure. I only mix the native mft electric lenses with glass like the Voight and SLR if it's my only solution. For example if I need IS for some odd shot. For what reason do you want the SLR 12mm? Is it just for a wider shot? If so, I'd say save your money. Do you want to unique look and cool flares? Well then that's the lens you need to get. What's the subject of your shoot? Talking heads? Cats? Artistic landscapes? This is where you'll get your answer. I'd say you prob have all you need in the 14, 20 and 45 to shoot what you want. The 20 is a great low light lens and sharper at 1.7 than the 12mm is at say, maybe up to 2.8 or maybe even 4. I could be wrong there. If you're really worried about a wide angle, you could get the adapter for your 14mm. They're pretty cheap but it won't be that great for night.

@tenjin I use the Voigtlander 25mm with the 12mm and they match up quite easily with only minor corrections. The SLR is a bit more yellow and with less saturation/contrast but the same mojo is there.

Well, you're kind of all over the place there with lenses so I don't think it really matters.

I think the bigger question is what look you are going for. There's no way that SLR12mm is going to cut with that Pany14mm and prob not the 20mm. They are completely different looks. So if those are you only other two lenses I wouldn't buy the SLR. If you're going to be shooting alot outside I would go for the 14-140 to match. Just my 2 cents :)

I have a shooting for a personal project scheduled for this fall. I'm wondering if i should buy this SLR lens... I already have pany 20mm and 14mm but I might find the focal length with GH2 and especially GH3 may not be wide enough... Is there a big difference between 12mm and 14mm on GH2/3 ? I don't know if it would be worth to buy it. Thanks for your advice.

This lens will eventually force me to eat my tie. Earlier I was so much pessimistic about 12mm SLR magic due to extremely bad copy received initially. You may easily find my earlier posts above where I suggested to stay away ftom it. After some period of time I ordered it again in anticipation of BMDPCC release. The order was placed with a dealer, not directly. Again bad copy. Another attempt with the same dealer who agreed to substitute the lens was succesfull. Although the third copy still has some minor mechanical issues the image is very much pleasant. Nowadays, this lens stays with GH2 95% of my shooting time. So, please make sure that you have a possibility to choose from several copies of the lens at the moment of purchase. The lens is amazing for GH2 provided a good copy is obtained.

What version 2? Why do you people keep talking about 2 versions. It's all the same glass, they just snapped a gear on it. Yep, it's official, the search function must not be working on PV.

This was shot a few weeks back using the 12mm exclusively. I have a step up ring and a 72mm 0.9ND filter from Tiffen, adding a bit of vignetting. I meant to showcase some of the lens characteristics and flares, which in my opinion are absolutely amazing with this lens. I have the panasonic/leica 25mm f1.4 also, but I rarely ever use it anymore since I got the 12mm. The focal length is great for all kinds of fun stuff and everything just looks really good with it on.

@vicharris I know you showed me this lens, but, what's your thoughts @ 1.6, wide open, night time, in terms of focusing towards infinity. Is there decent enough sharpness on the background to have buildings decently enough rendered for a 1080P feature film/doc, or am I stuck at F2.0, or beyond? thx!

bought a used from a guy in my country. He ensured that it was fine - and so it was. Nice lens and which was charged off quite soon

I would love to buy this lens..but since I live in Brazil and I cant afford sending the lens back and forth to US to replace/fix ...I am giving up ...many reports of problems make this one a unreliable piece of glass ...or am I being a little harsh ?

I'm currently thinking about adding a zip gear to the aperture ring somehow...
