Elegantly designed with a sharp, metallic black finish, the new 30mm macro lens perfectly matches the style of the latest LUMIX G interchangeable lens cameras. With a 30mm (35mm camera equivalent: 60 mm) wide angle and a high speed f/2.8 aperture, the lens provides sharp, high contrast image rendering. Utilising 1x life-size magnification, deep depth of field, and a focusing distance starting at just 0.105 m, the lens offers excellent performance even when shooting true-to-life macro shots.

A durable and reliable metal mount means the lens is perfectly suited for day-to-day use, while the multi-coated lens elements minimise ghosting and flaring to further enhance shooting performance. With a 240 fps Drive Auto Focus (AF) and MEGA O.I.S. (Optical Image Stabilizer), you can achieve fast, accurate focusing and stable framing with every shot.

The 30mm macro will be available in black from May 2015 for around 399.

From my standpoint, the Sigma is better at shooting people and has FAR less breathing issues, but it is not as optically perfect as the Samyang, which is far sharper and has no barrel distortion. On the crop of the GH2, the 35mm makes less sense than it does on aps-c and even less than on a 5d (which I find it looks great on). The sigma doesn't have a dedicated aperture ring, but I do have a Novoflex Nikon to m43 adapter, so I'm personally all set to buy the Sigma, if it is ultimately going to be the right move...I know that, while there is a lot of focus breathing involved with the Samyang, and it isn't the best at shooting people in a 'naturalistic' kind of way like the, it does look great as a general composition tool and would probably end up taking optically better photos with.

Right now I have the tamron 17-50 f2.8, a minolta 24mm f2.8 (which I'm thinking about selling dependent on which lens I'm getting), a SMC 50mm and a Nikon 85mm f1.8d. In many ways, I wish I could just buy each of the voigtlanders and call it a day, but alas, I haven't sold any organs on the black market, yet...

How do you guys way in on these two lenses? Do you think there's a lens in this range that I have't considered enough of yet? I'm also thinking of going with the 25mm leica f1.4 and getting the voigtlander 40mm to go with it, but so far I've just been really enamored with both of these lenses. Any help or suggestions would be greatly appreciated!

The lenses I am currently considering are:

Sigma 30mm f/1.4 DC HSM (art) for Canon EF

Rokinon/Samyang/Bower 35mm T1.5 for EF

If anybody has used those lenses, please offer your opinions. I have been impressed by the Sigma footage I have viewed but understand the Rokinon has stronger qualities for video - however, is very soft at 1.5.

I managed to use my school's dolly to pull off some test shots for smooth camera movements. Take note that I used and controlled everything singularly: I pulled focus, performed pans, and physically pushed the dolly itself. It was difficult, but I managed to get some usable footage. With one or two extra grips I can easily pull off great looking, smooth shots. I'll be shooting more with the dolly this week. I like grain.

The Sigma 30mm is fairly sharp but not stellar across the frame from F2.8 thru F8. Starting with F11, the effects of diffraction start to blur the images. I have not tested vignetting but I don't see it in my test shots and it is unlikely to be an issue because the lens was made for a larger image circle. The main problem that these test shots reveal is chromatic aberration, which can reduce the positive impression of a fairly sharp lens considerably. Interestingly, chromatic aberration is not corrected even on a Panasonic body.
