This is a superb lens! You can expect extraordinary sharpness right from wide open. Smooth Bokeh and no, and I say again, no chromatic aberrations. The lens distinguishes itself by having excellent separation of the subject from the background, it’s very 3D. Colour contrast is high and images need very little processing when coming from dng files. The lens has a very special look, especially at mid-distances. Close up performance is also very good, due to the floating element. Close up images still retain interesting bokeh as well. Check out the parrot shot below. Vignetting also serves to enhance image quality ( I know that some will disagree), but I really like this lens and its output.
I am working on the review of this wonderful lens, that is sadly discontinued by Leica. It is a very light small lens ideally suited for travel. The nearest modern alternative would be the 90mm F/2.8 Summarit. The F/2.8 Elmarit is available on EBay and if one is careful, you can pick up a very good copy.
We have been busy adding new images to the stock inventory! Here is a sample of our portfolio:
A great lens, not quite as good as the new Leica 18mm, but much, much cheaper. This test was done on a Sony NEX 5n, so it will not represent true corner performance on a full frame. You can get an ides of the lenses characteristics though. The lens itself is tiny, it weighs 350g and is 71mm long. Distortion is well controlled, you can expect some lateral chromatic aberration in the corners, but it is easily corrected. Specs:
Probably the best 28mm F/2.0 lens in existance right now! This is a stunning lens, with NO chromatic abberation, excellent bokeh, and its super sharp right from F/2.0. In fact stopping it down only adds to the depth of field, it does not get any sharper from F/2.0 onwards! A feat of engineering thats for sure. Anyway, a picture is worth a thousand words, so have a look.
This is the last version prior to the Summilux Asph. Designed by Peter Karbe, it sort of transitions between ealier Mandler designs and the current Asph, which is also designed by Mr. Karbe.
It is a 7 element, 5 grouping design with a 12 blade aperture mechanism. This mechanism yields almost perfectly circular bokeh throughout the aperture range. You can expect half click stops between the aperture settings.
A superb small lens for the M system! This lens has drawn a fair amount of criticism from Leica shooters. It has been branded as having poor mechanical parts and being optically inferior.
Are these accusations true? We will find out! First let have a look at the specifications as from Leica:
Yep its quite a mouthful, but the Contax 17-35mm N Mount – EOS conversion lens offers very good wide angle performance on the Canon SLR. Its a big lens, that is no lightweight, weighing in at 900g or 2lbs! it requires 95mm filters. Optical performance is very good for a wide angle zoom, it is not perfect, with somewhat softer corners at wide apertures. With one or two exceptions this type of wide angle zoom performancer is the norm for almost all manufacturers. Lets talk about the good, and there is plenty of that Zeiss look! The lens renders with that 3d zeiss look that we all like! It shows great macro contrast, good shadow illumination and reasonable chromatic abberations or CA for short. CA is almost a non event these days, and lightroom deals with very well. Wide open at 17mm you can expect a full stop of fall off (vignetting) this decreases to about 2/3rds of a stop at F8. Fall off at 35mm is less, with about 2/3rds of a stop wide open and a little less than 1/3rd of a stop at F8.
