    MFT lens 100-400mm, Leica DG, announced

    From what I have seen from the 100-400mm Leica it should be sufficiently sharp in the center at 400mm, but slightly softer at the edges, if not shooting brick walls, not an issue. https://www.cyberphoto.se/info.php?article=pana100400 The Olympus 300/4 is probably one of the sharpest 300mm...

    MFT lens 100-400mm, Leica DG, announced

    :-O Perhaps, but most (if not all) super telezooms are a bit weaker at the long end so the results are not that surprising. Ephotozine review shows a similar trend (but not quite the same drop in edge sharpness..)...

    MFT lens 100-400mm, Leica DG, announced

    Not sure what you mean, the quote you refer to is just an introductory discussion, they did a lot of testing. More tests than I have seen in other reviews. But the results at 400mm looks not as sharp as I have seen elsewhere. Feels a bit strange. Shutter shock problems? Air/heat movements? This...

    Nice shots, how do you find birds in flight? 50% in focus? or more? less?

    MFT lens 100-400mm, Leica DG, announced

    Perhaps a bit better (originals where over sharpened) but many of the photos unfortunately seem to show signs of diffraction, the european roller and the white-crowned sparrow for example, not sure why to use f/10 or even f/13 on a 20MP MFT sensor, I would't use smaller than f/8 with this lens...

    MFT lens 100-400mm, Leica DG, announced

    speculating a bit on bokeh, the DOF is actually a bit shorter for the leica at 400mm/6.3 than for the Olympus 300/4 at 10 meters it's 0.11 m vs 0.13 m, at 300mm it's the opposite, obviously as the leica is only 5.6 at 300mm this is pretty small differences and the actual focus lengths might not...

    MFT lens 100-400mm, Leica DG, announced

    It's a reasonable size, and price, if the image quality is as good as expected. Really hope that the AF performance will be good enough for birds in flight with the E-M1. 4 stops of in-lens IS would be nice to. Would be using it mostly for documenting birds. So it will probably be more...

    slrgear.com got 100% good shots at 1/15 sec! "In our testing, the Olympus 300mm ƒ/4 Pro's image stabilization using the E-M1 v4.0 was fantastic. Our lens technician Rob has quite the steady hand to begin with and, as you can see from our graph, was able to get about a 40% keeper rate of "Good"...

    MFT lens 100-400mm, Leica DG, announced

    yes, very good for shooting stuffed birds! ;) but still might be useful, in some situations, being able to lower the ISO, especially since high ISO is not super on the micro 4/3:s small sensor, but I totally agree that IS is a bit overrated for bird photo

    The new Olympus 300/4 IS Pro no doubt will be sharper since it's a prime, especially edge sharpness will be better. From what I have seen in test shots it's probably in the same level as Nikons and Canons latest super-expensive primes. MTF:s even for good zooms always look a bit "worse" in...

    here is the MTF for the Panasonic 100-300/4-5.6 Lumix Mega OIS lens for comparison, you can see that it's good att 100mm but looses significantly at max focal length. the test shots I have seen with this older lens does not look bad, but they lack the last bit of contrast and sharpness (can be...

    MFT lens 100-400mm, Leica DG, announced

    * generally you could say that closer to 100% is better * the blue lines indicate "sharpness" (lower cycle pattern, 20 line pairs/mm) * the green lines indicates "contrast" (higher cycle patterns 40 line pairs/mm) * the dotted line should follow/be as close as possible to the non-dotted line of...

    MTF diagram for the Leica 100-400 DG, seems so be optimized for the max focus length and very sharp at 400mm

    seem to be the same guy as in the panasonic promo I linked to, not very flattering light on the photos, and too small pics to really see how it performs but the size an weight look very reasonable to me, as he writes in his blog "This is the lens I’ve been hoping for and it’s an amazing time...
