Sony Alpha 7 in Digital Cameras

Alpha 7R
Recent tests on the cause of light leak issues with Sony a7 and a7R cameras have found that the leak is down to the design of the cameras.

Tests, carried out by lensrentals.com, found that the light leak is more severe with the 35mm f/2.8 Sony lens mounted. It also found that the leak is worse when fiberoptic lights were shone into the lens release button area, and when shone directly above the lens mount and in the lower left quadrant of the mount. 

These light leaks could have real world implications for some photographers, and several quick fixes were suggested, including putting a scrunchie around the lens barrel and taping over the lens release button with black electrical tape. It was also suggested that using a weather sealed lens may help.

Testers made it clear that this is not an isolated problem, and that light leak issues have been found with several other brands of camera, too.

We contacted Sony about the issue, and they said: "We are aware of reports of light leakage on the ILCE-7 and ILCE-7R. This issue does not affect any photographs taken in normal photographic conditions, however we are currently investigating the concerns that have been raised."

Tisk tisk Sony, Light leakage in camera bodies is forte of LOMO, Everyone else tries to keep the light well away from the imaging medium, Except where it comes in from the front lens element.

Oh well, Back to the drawing board, Unless your trying to steal LOMO's thunder of course..Grin

Just another problem for Sony users that are dismissed with Japanese manufacturers disdain.

They don't have shutter shake either in the 7r.

let's see what wisdom the 19th brings from Sony.

Ah, but, to quote from the above:
'Testers made it clear that this is not an isolated problem, and that light leak issues have been found with several other brands of camera, too.'

So, what other cameras have they found with light leaks ( here I'm assuming that Lensrentals don't mean Lomos as I suspect that there isn't a great deal of demand for these on the rental market)?

It seems the Sony is not the only problem; it appears the sub-editors on EPZ need a makeover. I stumbled when I got to the second paragraph, which caused me to stop reading. 'Shined' is not a word, 'shone' is the past participle of shine. Come on chaps, I expect at the very least from this site a reasonable command of the English language.

Thanks, this has been amended.

I would like to point out, however, that shined is a word, but was used here in the wrong context. Apologies for that.

When is anyone going to shine fibre optics at the camera in this way in real world situations?

Just completed a shoot where I was blasted with stage lights and never got a sniff of this problem.

Had no problems with so called limited battery life either and some of the other complaints levelled at the Sony.

I suppose you can find fault with anything if determined enough.
