Pros: Small size, lightweight, well built, sharpness

Cons: AF slightly noisy and not lightning fast but perfectly fine! 100% recommended optics

Opinion: I bought a couple of days ago this used lens but in excellent condition, it looks new, complete with caps. The first thing I noticed is the lightness and size. really comfortable. I have grafted this lens to an Olympus Em10 first silver version and makes its beautiful visual figure: it looks like an analog SLR of a past time. The autofocus I confirm that it is not lightning: I did some tests with dogs that are moving subjects, when it focuses, now the dog has moved. However, if you have to take different photos, with subjects not too fast in movement, the photos are fine. From the first images taken, I immediately understood that it is an excellent lens, which makes you take excellent photographs. At TA (f 1.7), it creates sharp images in the center and as you look towards the outside of the image, you will notice a slight softness completely normal, understandable and above all real. The detachment of the planes from the subject in focus, is very beautiful, typical of lenses with very open diaphragm. I followed and kept an eye on this lens for a long time between photos, user impressions and the price on the second-hand market. I managed to find a practically new specimen at 150 euros shipped. Satisfied with my purchase, recommended to all, absolutely to have in your kit micro four thirds. Finally there is the second version on the market, from what I could understand, apart from the different external coloring and the decidedly higher price, there are no substantial differences.

Pros: size, weight, sharpness, yield even at full aperture, pleasant blur, also price

Cons: af a noisy wire. for me the speed is enough

Opinion: optics to have. 40mm sharp angle of view even at full aperture. I really like the yield. tiny and also cheap. well built. some limits in autofocus but not relevant for me. For me the essence of the M43. Reduced maf distance that combined with the wide aperture makes it also excellent for close-up shots (flowers etc). For those who do not have wide angle needs pushed, it can be paired with a light canvas. I would find it perfect with the 45-175

Pros: Size, speed, sharpness, build quality, manual focus difficult to change

Cons: It lacks the scale, easy to shift the focus unintentionally

Opinion: It is my lens favorite, is perfect for the road (street and human compositions), although sometimes I regret the absence of stabilization, especially when I forget to increase the times. I kept on G1 and GF3 mainly in manual focus. G1 is nice and quiet, of G1 starts to be "big" and put a little 'of ansia.rnrnPer the street photography "quick" does not make sense to use the automatic focus, poor equally to that of the SLR. In static conditions at f / 1.7 it never fails, and often leaves surprised by the speed and precisione.rnrnLa vignetting is very visible at 1.7 but not unpleasant. Defocused 1.7 is very light, often do not notice it in the few cases where need is very small gradevole.rnrnÈ but does not go unnoticed, it is considered a real target, then on the road receives her dirty looks.

Pros: Optical performance, compactness, brightness, focus.

Cons: Panasonic should offer it more widely in a kit with the Lumix.

Opinion: I love this focal length and the fact that it was in a pancake, bright, and that is second to none has made me choose as my first optical micro kit. Ideal for street and reportage. He's doing very well with portraits and landscapes, it is a standard focal length, so it fits well in many situations. The optical performance is always of a high standard in all light conditions, in all respects and any opening. Many complain of AF, it is definitely improved but still good, it will not be the fastest but I think it is too slow to call it, is always silent and precise.

Pros: size, light weight, grade 'optics, focal universal.

Cons: manual focus without awkward scale.

Opinion: It 'a lens to have in each kit m4 / 3. The quality 'and' sorrpendente also to F1.7. And a blurry good 'excellent isolation of the subject. It 'a universal focal length that is used everywhere and for any subject. The focus manually without scale and without limit and 'uncomfortable and not very usable in low light. Perfect for Street.
