jankap Posted November 13, 2014 Share #4541 Posted November 13, 2014 Advertisement (gone after registration) How is it with adding deadweight to the A7r? According to the articles of Josef Holmes about 24 ounces, around 700 gr. = a medium heavy lens. The problem comes from physics, namely the law of conservation of impulse.

naturephoto1 Posted November 16, 2014 Share #4542 Posted November 16, 2014 How is it with adding deadweight to the A7r? According to the articles of Josef Holmes about 24 ounces, around 700 gr. = a medium heavy lens. The problem comes from physics, namely the law of conservation of impulse. Jan I haven't tried this option and I also don't know how long the lenses that have been used by Josef Holmes. I have been using the set-up in various versions with my R 100mm f2.8 Apo-Macro-Elmarit, R 180mm f3.4 Apo Telyt, and my 280mm f4 Apo Telyt lens alone as well as with my R 1.4X Apo Extender and my R 2X Apo Extender. I suppose that I could try to clamp the entire RRS Long Lens Support Package with the ProMediaGear Back to Back clamps to act as the weight and clamp it to my RRS L bracket for the A7r camera. It might be worth a try, but I still suspect that we are not only observing the camera itself moving as a result of the shutter shock but also as a result of vibrations running through the entire camera and lens assembly.

jankap Posted November 16, 2014 Share #4543 Posted November 16, 2014 If you would would bounce at my body with maximum velocity, that would be different from bouncing at a Sumo ringer. The point is, that the shutter of the A7R would have little effect on the A7R, if the camera weights 1000 grammes (A7R + 700 gr). The weight should be mounted as close as possible to the shutter and be not too large. My proposal of a medium heavy lens (e.g. Lux 80mm) is wrong of course, because the weight would be not very concentrated. Jan Link to post Share on other sites More sharing options...
saxo Posted November 19, 2014 Share #4544 Posted November 19, 2014 The successor of the A7 is coming soon, maybe called A9 ( (SR5) New PRO Full Frame A9 E-mount camera is placed above the A7 series. | sonyalpharumors ) and Sony may have not only solved the shutter problem, but also added 5-axis stabilization. I hope Leica is coming up with a new model early in 2015. The M-Mount has still advantages, but a EVF-Version of the M with a state of the art viewfinder, compact zoom-lenses and reasonable macro-lenses are still missing. Till now, leica is a good second camera, but has the potential of beeing a good first camera. If this will come true, depends solely on the manufactures strategy. I'm not so sure about it.

Steve P Posted November 20, 2014 Share #4548 Posted November 20, 2014 price estimated to be about $1600 / € 1300] Great news generally but I'm taking any price guesstimates with a large pinch of salt until officially confirmed!

indergaard Posted November 20, 2014 Share #4549 Posted November 20, 2014 Great news generally but I'm taking any price guesstimates with a large pinch of salt until officially confirmed! Hope they manage to fit some kind of silencer to the sniper rifle shutter sound. There's also no mention of weather sealing. Cause the first gen A7's for sure are not weather sealed, even though some people say so. None of the openings for ports, the battery or memory card have any kind of gaskets, so it can't be weather sealed. I don't like the increased weight. Suddenly the camera + adapter is the same weight as the M240 without a lens. I don't like the bigger footprint and grip. 5-axis IBIS with 4.5 stops compensation is awesome though. Put a 0.95 on that thing and shoot hand-held in complete darkness without any problem what-so-ever. IBIS is also very good for video... This only makes me wonder when the A7R II and A7S II is going to ship. The A7S was announced in June! So having a replacement ready for it this early makes no sense... But then again, the 5-axis IBIS would be awesome for video - which is one of the strong selling points of the A7S. Fitting 5-axis IBIS and 4K internal recording on the A7S II, and it would sell like hot-cakes! And pair it with Zeiss Loxia lenses with the de-click option and smooth mechanical manual focus, and you have a very good combination indeed. Link to post Share on other sites More sharing options...

The rumour site's spec list mentions - "Environmentally sealed Yes" - whatever that means. It remains to be seen whether that is confirmed in the official specs when they are published.

If you take a look at the link you will find several links to Sony's japanese website, where all the information is taken from. People also claimed that the A7/R/S were weather sealed. Something they in fact weren't. Link to post Share on other sites More sharing options...

indergaard Posted November 20, 2014 Share #4554 Posted November 20, 2014 Sorry but people didn't claim it was weather-sealed Sony did (at least to a degree) [ATTACH]469293[/ATTACH] Still the battery door (bottom), SD card door (rear/right side), and the flaps for the ports on the left side are not sealed in any way. This is easy to see by simply inspecting the openings. Seems like it is a poor attempt to weather seal the top of the camera, with the assumption that most people will experience rain drops from above, that will hit the top of the camera. If the camera is mounted on a tripod in portrait mode, however, especially with the left side up, there is basically free entry into these ports: headphones out, mic in, mini-hdmi and micro-usb.

indergaard Posted November 20, 2014 Share #4555 Posted November 20, 2014 It seems to be a lot more bulky than the current A7/R/S design. And with the added weight (+150g approx.) it's just a bit too much in my opinion. It's not far away from the weight of a Nikon DF. And even with the much larger grip they use the same battery even though they should have been able to fit a much bigger one. It's simply starting to look like one of the smaller Nikon and Canon DSLR's in size now. And with the ever increasing large native lenses... I think my A7S will simply stay as my low-light alternative for my M-lenses and a backup body to the M240, as well as what I do movie recordings on. Sony A7 II and Sony A7 are the same width (126.9 mm) and 1% (1.3 mm) taller than Sony A7. Sony A7 II is 24% (11.5 mm) thicker than Sony A7. Sony A7 II [599 g] weights 26% (125 grams) more than Sony A7 [474 g] (*inc.battery and memory card). http://camerasize.com/compact/#579.394,487.394,ha,t Link to post Share on other sites More sharing options...
colonel Posted November 20, 2014 Share #4556 Posted November 20, 2014 Hmmm Not sure about close to any FF DSLR The Df is 756g and the A7ii is 556g That's clear blue water especially when you take the much smaller body into account And it's got ibis !!!!!!

And wifi And video Etc According to Sony.jp's website it's 599g with battery and memory card: Put a Voigtländer VM-E M-mount adapter (a very popular adapter, and considered to be the best available) on the A7II and it weighs 724 grams - 41 grams more than an M240 incl. battery and card.

colonel Posted November 20, 2014 Share #4558 Posted November 20, 2014 True, but we are still in the low weight zone, remembering that the A7ii is a full AF system and the adaptor for another system is extra. The M240 R series adaptor is over 200g .... And there can never be an adaptor for the Df to take Leica lenses ..... Link to post Share on other sites More sharing options...
zlatkob Posted November 20, 2014 Share #4559 Posted November 20, 2014 It looks very appealing, even if a little larger and heavier. With the redesigned grip and new shutter button placement, the ergonomics appear to be improved over the A7. I wonder whether autofocus points can be selected quickly and easily. I do wish it had a longer lasting battery. Link to post Share on other sites More sharing options...

OK from 65mm upwards, with short mount and Visoflex lenses, I have a Fotodiox Viso to Nikon F adapter, and it works well. I almost began to think of my FM2 as a Visoflex F Gerry Link to post Share on other sites More sharing options...
