Summary: I feel that I don't have to review the image quality anymore. As there are more professional reviews and users have already done. However, I'd like to generally state 2 points here. 1.) The focusing is slower and noisier than the Micro 4/3 version. The turning sound is actually not very smooth, and louder than some of the Nikon and Canon USM lens. 2.
Summary: I rented this piece for a couple of weeks to knock out a couple weddings and some portrait sessions using my Olympus E-3. Let me start by saying that it's an impressive performer and will give you tack sharp images all the way down at f/1.4. I've got a couple of the High End Zuiko lenses and I haven't seen this kind of performance from them. I have to say, with the low light limitations of the Olympus E-series cameras, a prime lens of this caliber is an essential item.
Summary: I was really excited about trying out this lens Excitement lasted about the time it took me to open package Does not even come close to fitting on my GH2 How silly of me to think a LUMIX lens would fit on a LUMIX camera
Summary: So I know that the 20mm f1.7 is a covetted lens on all M4/3 camera users gear list. I recently sold mine to take a chance on this lens. I was heavilly rewarded. The kicker for me was a the speed of the lens. I shoot predominantly in low light or in the always difficult varying lights in the house. I find this lens on my camera more than anyother.
Summary: I bought this lens a few months ago from Amazon for my four thirds Olympus E5,E3 and E330 cameras and could not be happyer!!It is fast focusing,and works great in low light and also a great prtrait lens.The price is ok at $899.95 which I paid for it,but I think the $1325.50 is a bit off!!!It is a big lens,but most modern auto focus lenses are much bigger than similar hand focusing(film camera)lenses.
Summary: I have some seriously mixed feelings about this lens. On the one hand, it's good, and I love shooting with it. On the other, its price is borderline obscene. It's an oddity of the Four Thirds system that fast, normal primes are so scarce. There's so little competition that this lens almost wins by default: there's the Olympus 25mm f/2.8 Pancake Lens which is far too slow; the Sigma 24mm f/1.8 EX DG which has a fiddly AF/MF clutch mechanism, isn't designed for four...
Summary: While this lens is not as sharp as the Olympus 50 f2, it's amazingly sharp at f1.4 and renders that Leica "glow" to photos. It provides some of the most beautiful and pleasant bokeh. Photos are creamy. Color is smooth with good contrast, but less pronounced than the Oly 50 f2. This is not a negative as not every photo requires that bite. I have used it on a Panasonic L1, Olympus 420, 520, E3 and E5.
Summary: If you're looking at this lens, you know what it is. It's a classic, standard angle, fast prime lens. The low light performance at f/1.4 is great. AF speed is slow though on my E-600. I believe the internal mechanism on the lens itself is slow. It does lock on in some pretty low light situations though (just not quickly). There is some vignetting at f/1.4 and f/2. This is largely gone by F/2.8 or f/4.
Summary: I agree this lens is brilliant - sharp, superb smooth bookeh, and great low light performance. This prime lens (i.e. it is not a zoom) forces you to be in the scene which makes for a more authentic almost immersive viewer perspective as the perspective is very close to the human eye.
