Thomas Chen Posted December 15, 2014 Share #4602 Posted December 15, 2014 The A7II doesn't have the silent electronic shutter that the A7S has. Thanks for comment. In fact A7 II does have the electronic shutter. If one reads page 147 of A7 II Help Guide shown below: https://www.dropbox.com/s/v5ho7au1o35tqkm/A7%20II%20Help%20GuideI.pdf?dl=0 he can set the " e-Front Curtain Shutter" as On or Off and the default setting is "On".

viramati Posted December 15, 2014 Share #4606 Posted December 15, 2014 I have both the A7II and the A7s and yes the A7II shutter is more subdued and closer to the M240 (which I also have) but a little louder. Of course the A7s has the full electronic shutter which is totally silent but has it's limitations especially in fluorescent lighting where you can get severe colour banding at anything over 1/100thsec Link to post Share on other sites More sharing options...
viramati Posted December 15, 2014 Share #4607 Posted December 15, 2014 Advertisement (gone after registration) David, Congradulation! Your findings encourage me to consider acquiring another A7 series camera. If you have a Leica Summicron 28/2 ASPH and a Elmarit 21/2.8 ASPH, please advise whether these two lenses engender red color shift and smearing at the corner in the image. Thanks and Best Regards, Thomas Chen Don't know about the 21/2.8 but unfortunately the 28 summicron doesn't perform well on the A7 or A7s with severe smearing in the edges and corners even when stopped down + heavy vignetting. As this is my most used leica lens it is really my main reason for keeping the Leica M Link to post Share on other sites More sharing options...
Rick Posted December 15, 2014 Share #4608 Posted December 15, 2014 Do they? Or just in relation to some third party lenses? Yes, it is all lenses as far as I know. The sensor glass cover is too thick and causes smearing with many lenses and with all lenses there is some degree of flare which would make the A7 and A7r a no go for me because, I like to do night cityscapes.

The sensor covers are not too thick, they are perfect for the design This would have nothing to do with flare anyway, that is a lens issue It's because Leica lenses are not properly corrected. It's purely a problem with Leica lenses. Karbe was asked why he didn't change the M design for digital to be properly corrected, he said that it would immediately make all old Leica lenses obsolete. They wanted to keep a link with all M lenses and thus instead chose to angle the micro lenses. Which they couldn't do with the M8, hence the APS-h sensor. Until the M9. For the T they started from scratch and T lenses have parallel corrected rear elements Rgds Link to post Share on other sites More sharing options...

Sensor flare on Sony sensors, I believe, is worse dependent with how close the rear element is to the lens and the exit pupil of the lens. It has nothing to do with Leica M-lenses, although the further the exit pupil the worse the sensor flare is. I thought this had been discussed here. If not, then Google it and read about the problems with the Sony sensor flare. It happens with Sony(Zeiss) lenses as well and it is subpar. (Iwill have to go and reread, but I thought it was also due to the thickness of the glass, but it could have to do with other design flaws with the sensor.) The too thick sensor glass is definitely the cause a falloff in resolution even in the Sony lenses. It is hard to beat the peripheral resolution of the Leica sensor because, the design needed to be thin to utilize the old lenses. The benefit was greater line resolution in the Leica sensor as compared to designs that use thicker glass. This is seen in what appears to be more falloff of resolution of the Sony(Zeiss) lenses than would be expected in tests I've read. The Leica sensor in tests I've read, continues to hold up in the periphery of the sensor and even surpasses the A7 series. Rick p.s.

viramati Posted December 16, 2014 Share #4611 Posted December 16, 2014 Sorry but I own both the A7 (now sold for the A7II) and A7s and have just skimmed through around 4000 images taken with these cameras and have found no issues of sensor flare in any images and even those at night with brightly lit lampposts. For me this is a complete non issue. I also see no fall off in peripheral IQ due to the sensor glass thickness for example I find the FE55/1.8 to give me greater micro-detail across the frame even wide open than my lux 50 asph on the M240. The FE24-70 may have some falloff in the corners at 24mm but the new FE16-35 doesn't appear to suffer from this and appears to be an excellent lens. Early adopters of the A7II seem to be reporting an IQ hike but it is early days to confirm this. see pages 4 and 5 http://www.getdpi.com/forum/sony/52742-new-a7ii-users-reports.html Link to post Share on other sites More sharing options...
k-hawinkler Posted December 16, 2014 Share #4612 Posted December 16, 2014 Thanks David, you have certainly shot some remarkable images with the A7 II and FE 16-35 lens.

I like your shots a lot, especially the one you called "Duality".The GetDPI Photography Forums - View Single Post - Sony FE 16-35/f4 Those certainly are great shots. And, I'm pretty sure you selected them because, they are lens starburst shots that do not exhibit sensor flare. You misunderstand the condition that causes the flare. Sony sensor flare is a problem at the edge of the image, not centrally. Link to post Share on other sites More sharing options...

viramati Posted December 16, 2014 Share #4618 Posted December 16, 2014 As I said before in over 4000 images I have shot with these cameras I have never encountered this problem even with light lampposts at night towards the edge of the frame. Someone may have experienced and they will have their explanations but this, at least for me, is no reason not to buy this excellent image making machine.

colonel Posted December 16, 2014 Share #4619 Posted December 16, 2014 I used to have a A7. I now have the A7S. After a long history with cameras, including a D800E, 6D, 5Dii, etc. I can say with confidence that the A7S is the best AF camera I have every used. It's bitingly sharp corner to corner and has a pop that Reichmann referred to as medium format like. The A7 was excellent with no issues with prime lenses as I understand it. This all seems very theoretical and unproven. I would stand by my statement that the A7S, apart from tracking AF which I never use, is close to flawless.

viramati Posted December 16, 2014 Share #4620 Posted December 16, 2014 I have to say that it is hard to choose between the A7s and the A7II for my so called 'camera of the year' At the A7s is astounding in what it can do in low light and has beautiful files. It is early days with the A7II but it goes without saying that now having both these cameras I feel I can tackle almost any situation which I unfortunately can't say for the M240. If only i could get a small 28mm lens with a DOF that worked well on the A7II I would probably sell my leica M, I have the rokinon 28/2.8 which performs well on the A7s but not so well on the A7 Link to post Share on other sites More sharing options...
