Sergey Borachev: There is something very special about this lens, something that is seldom talked about. It is not only sharp but IT IS SHARPEST AT MAX APERTURE!

This is very useful for capturing portraits with bokeh as well as for freezing moving objects. You don't want to stop down this lens, except when you need more DOF.

Check the Lenstip review. This lens is unique.

Check the comparing tool here at dpreview comparing say a lumix G9 with a Sony a72 or 3 at iso 200 the G9 doesn't cut oof that badly at all. At iso 3200 it isn't that sharp anymore. By the way, taking a photo at f5.6 with FF will not always give you as good a photo as MFT with F2.8, as the shutterspeed will be lower on the FF causing more motion blur ;)
s for your comment to mft being for snapshots? There are plenty of pro's who use mft to earn money, making really good photos with satisfied customers....i guess they don't know what they are doing.....
Before accusing others of being ignorant and brainwashed, go look in the mirror and check your physics text books.. maybe you need to correct you view aswell....

@ ecka 84 you said"let's say given F-number gives you 100 lumen/sq_meter on the sensor. Then with m43 sensor you get 100 lumen/sq_meter * 225 sq_mm = 0.0225 lumen. With FF sensor you get 100 lumen/sq_meter * 864 sq_mm = 0.0864 lumen." The calculation doesn't work that way… the ratio is determined by the diameter of the lens compared to how much it is focused on the sensor. The FF sensor may be 4 times bigger but at F2.0 it is getting 4 times less light per square mm than an MFT sensor at F2.0. But as the FF sensor is 4 times bigger it ends up with the same total light hitting the sensor. just like a magnifying glass at different distances to an object. The difference between the two formats is DOF an noise from the sensor. MFT has more noise as the pixels are smaller. In good light you really can't tell the difference (even pros can't) in low light its a different story, as the ISO increases MFT gets a lot more noise.

It depends on the light per surface area…. the mft sensor may be smaller but the light is bundled tighter. F1.2 gives you the same amount light per square inch independent of sensor size.

Watch these videos, where it is explained well: https://www.youtube.com/watch?v=LxZe4MuM8_Q

F2.8 is F2.8 …. the amount of light hitting the sensor is the same...the only difference is the the DOF and look.

I have disqualified one photo because it was supported by vote rigging
(two voters gave 34 photos 0,5 points and one photo 5.0)

Isn't this a different crop of a photo from the previous wedding ring challenge?

Hey! i took an almost identical photo in the Cape Town aquarium..... The tank had a blue backdrop, interesting that the effect turned out similar to an ocean photo....

On photo The Shell in the - Macro : Elegant Curves- (Full Colour Only + Border, Title, Date) challenge (2 comments in total)

Thanks :) the other photos are very good as well.... I think getting in the top ten is good enough, getting a higher ranking is also a matter of luck.

I put the shell in an old silver gravy pitcher, which causes the interesting reflection of the shells spines.

Wonderful photo!
I only find it ironic that kites being pushed up by the wind and held in place by a string (in other words "trapped" in the air), symbolize freedom? ;)

Are you sure that this photo was not taken in the arctic SUMMER?
