Question: Does this work with Panasonic DMC-G5KK
Document: Aside from the rattling sound when this is attached to the camera and off (normal according to the various sources I have read), this lens focuses fast, is sharp and has very good color rendition.I took away 1 star because the focusing barrel is smooth. A little texture for added grip would be good.I am using this on a Panasonic GX1
It is a great lens for M4/3. Definitely worth the money. It is larger than I expected considering the size of the Panasonic 14mm. I don't give it 5 stars simply because I have mounted some of my old manual focus Nikon and Minolta lenses on the camera with adapter and they all out preform this lens as well as every other Micro 4/3 lens I've put on the camera. Those old lenses are pretty impressive.
Note that I am an amateur photographer and have only owned a single M43 camera (EPL1) and a single lens (kit lens) until now.This lens is about as large as the Olympus M.Zuiko 14-42 kit lens v1 (when not extended) that came with my EPL1. It came with a hood that seems to work well. The lens is heavier than the kit lens which is actually nice as it helps reduce shutter shock a little.
This verifies that each copy will not be one of the "bad" ones that people often seem to think they have, no matter which brand. Their website is interesting and discusses this change of focus (!) It is a company worth watching now.The lens hood reverses for storage, but that feature doesn't save much space.What Sigma has not evidently done is to actually change the optical design of the lens. People debate this, but Sigma has evidently not yet made any claims about improved optical performance.
This lens is available for both 4/3 and Sony Nex mount cameras. It is an updated version of the very well regarded original Sigma 19mm. These new versions are called "Art" lenses and there is even a little chrome Art emblem on the barrel to signify this. The other visual clue is that the focusing ring is now smooth rather than serrated. I think it looks sort of clean and modern.
This is true, but just rub the metal mount with your finger tips a little bit and it makes installation much smoother (the little oil your fingertips generates really smooths things out).
This is my third attempt to own a Sigma Art lens, after trying several legacy lens/adapter combinations on my Nex 7. I say third because the other two Sigmas went back due to the odd clunking sound the lens makes when it's not attached to the camera. I thought the lenses were defective, so I returned them. Then I spent a few months trying to find other lenses with the same image quality, with limited satisfaction.
This is an excellent little lens. Depth of field is great, autofocus is fast, manual is smooth. The lens is sturdy and well built, but nice and compact. It makes a great primary/walk about if a fixed lens is what you're in the market for. And for the price, I could not be happier.
There is a floating lens assembly that will rattle if you shake the lens. This is a matter of design, not a fault.The 19mm, along with the similar design 30mm, has received many great reviews for the optical performance. My lens tests are pretty much backyard comparisons, but clearly this lens is sharp and it carries its acuity quite a ways out from the center, where all lenses are pretty good these days.
The hidden part of the update is a more robust use of materials and construction. The ring will flex if you give it a grunt, it does not have that Leica hydraulic smoothness to it, but it is fine and not cheap feeling at all.Sigma has decided to emphasize quality design and construction, to move up and away from its sort of low-end reputation. Amazingly, It is actually Made in Japan by a family owned company.
Answer: The lens will work fine on the G5.
