Laowa 12mm f/2.8 and Laowa 15mm f/2 – 2 UWA lenses from Venus optics with close to zero distortion!
There were so many exciting gadgets on Photokina, that it was easy to miss two very interesting lenses. Luckily my friend mentioned Irix lenses https://www.facebook.com/Irixlens/, and while I didn’t find their stand, I spot instead Laowa. Venus Optics – producer of Laowa lenses is a new Chinese camera lens manufacturer based in Hefei, Anhui, which already delivered some rather unique lenses.
Laowa 15/4 Macro lens with shift ability is truly one of its kind, their 60mm f/2.8 Ultra-macro, goes natively up to 2:1 magnification, while 105/2 STF is one of the few lenses with built-in apodizing filter for ultra smooth bokeh rendition.
On Photokina 2016, we could see two new lenses – both with Zero-D designation, claiming to have almost no distortion at all. (Funny sign on the lens says – “Dreamer-D” :-))
I tried both lenses and in those very limiting conditions around Venus Optics stand, I found both lenses to be thrilling.
Lenses are not made up to Zeiss built quality standards (not they cost that much), but they feel quite solid in hand. They are fully manual lenses, which means not only lack of autofocus, but also of any electronic information sent to the camera – No EXIF, no focus distance report, no in camera lens profile correction, no automatic functions such as EVF image enlarging when turning focus ring. I am used to work with Samyang 14/2.8, so for me it is not a big deal to have fully manual lens, especially this wide.
There are few things worth mentioning:
1: Distortion really seems to be exceptionally low, with 15mm/2 I am not afraid to claim that it is well under 1%, but probably much lower and with 12/2.8 is just slightly more.
2. Image quality looks very good initially. I couldn’t detect much of CA and image is sharp up to the extreme corners (that falls well into DOF of course).
3. Both lenses are among fastest at respective focal length in the world (they are full frame lenses).
4. Someone very smart, said why we don’t put the mark for the middle of the entrance pupil (wrongly named Nodal point) on the lens, so panorama lovers doesn’t have to look for it by moving their camera forward or backward, trying to eliminate parallax error. There is a little red dot close to the lens hood, showing entrance pupil.
5. From (amazing) sample shots, it looks that both lenses have very well corrected coma, which is great news for astro-photographers. You can read full specification of Laowa 12/2.8 and see tons of sample images on their official site – http://www.venuslens.net/product/laowa-12mm-f2-8-zero-d/where you can also pre-order lens with shipping date starting at November
6. Both lenses are rather small and light.
7. For both lenses it should be possible to use 100mm system filters (LEE, Hi_Tech etc.) which is rarely case with UWA lenses (Most of them require 150mm systems, which are bulkier, and more expensive).
I can’t really tell about light fall off without proper testing, but it seems rather strong unfortunately. I couldn’t see on my Sony A7 MII corner color shift though.
I will try to get lenses for detailed review, and even if I don’t succeed in getting samples, I will most probably order them for myself.
They really made a very positive first impression on me.
While on above linked pages you can see several sample images, all really impressive, I can only show you few shots from around the stand, but it is still visible that distortion is really low.
