On article The Sony a9 is a 24MP sports-shooting powerhouse (1905 comments in total)

Sport tele lens idea: build a small (smartphone) camera module in the lens for an overview-mode in the viewfinder, like the old sport viewfinders. A wireframe shows the view of the real lens and one press of a button switches between the modes. Also save the photo (or video) from that camera module as a sidecar-image or in the Exif.

Does it still have a mechanical shutter?

rrccad: somewhere in the bowels of Olympus.. there's a poor engineer reading this announcement going ..


"Okay, when I said that *in theory* the processor should be able to handle 60fps RAW, I also mentioned that the storage subsystem would be the next bottleneck".

But the sales team didn't hear the last part and before the end of the meeting, the brochures were already printed...

1972 all over again, angry Leica, last-minute rename to YM1, first production run receives a YM1-sticker and becomes highly collectable :)

In reply to:

felix from the suburbs: Kind of a silly stunt. If the cameras still work, why destroy them? Can they not be donated to some school program or at least sold to a collector. I have some old film cameras that I only use rarely to shoot a few rolls of slide film, but I would never destroy them for the sake of being funny.

What else should we do with all those millions of mass produced old cameras, even if they're all wonders of fine optical and mechanical ingenuity? keep them only because of emotional reasons? The victims of this video are not very high end and don't have a lot of collectors value.

it would be sad if they crushed a Nikon F, a Canon F1 and an f/1.2 lens of one of those brands. But they didn't.

MonoSynth: But.. but... The iPhone SE has *exactly* the same dimensions as the iPhone 5 and 5s. This is most likely just rebranded old stock.

Dude! I'm talking about the case, not the iPhone SE. There's no difference between cases for the iPhone 5, 5S and SE. I have an iPhone SE (and love it) with an iPhone 5 case. Case manufacturers claiming to introduce a case for the SE most likely put their leftover cases in a new box with 'iPhone SE!!1!!one!!1' on it. That was my point.

Digimat: Nice Start, now a 35 1.8 and 85 1.8/2.0 in the same price range and size, and we finaly got a compact full frame system for a reasonable price.

Not gonna happen. Affordable non-50mm primes have always been in the f/2.8-f/3.5 range, brighter lenses are premium products.

NilsBV: Prices for those orphaned Sigma-mount lenses on eBay might suddenly go up, now that they are being given a new lease on life.

Until recently, Sigma lenses were nothing to get excited about. Besides, most Sigma bodies (SA-300 and such) were sold with crappy kit lenses to owners who never bought another lens.

beavertown: Why no Nikon??

The SA-mount has the same flange-focal distance and the same electronic contacts as the EF-mount. (source: Wikipedia)

On article Using third-party lenses on the Sony a7 / a7R (525 comments in total)
In reply to:

groucher: I'm really interested in this camera and was planning to use my ancient Nikon glass on it but I'm totally confused by this article. When using old glass with my D800, I put the camera in full manual mode and use the focus indicator. This is incredibly easy, particularly as the focus indicator is far more accurate than the old split screen method.

Is it that case that the A7's automation prevents a similar method to be used i.e. does automation get in the way? I'm particularly bothered by the use of focus magnification which seems to be an incredibly slow and error prone process, although I have no experience of using it.

I really like this camera for manual shooting. Focus magnification is just a double push of a button away, touching the shutter button disables it. Moving the focusing rectangle around is too much of a hassle, but you don't really need it.

Focus peaking is okay for slower lenses. The EVF is sharp enough to judge focus unless you shoot with f/2 or lower.

I use the camera as a light sealed box with a sensor, a shutter and a light meter and it serves me well.

I'm very, very happy with my A7 combined with my Hexanon AR 57mm f/1.2, same version as in the article. Mine seems to be a good copy, sharper wide open than most of the pics I see online.

Focusing is tricky, but after using it for more than two years (first on my NEX3/5) I'm getting used to it. The slightest movement of my body can cause the eyes to get out of focus (while the eyebrows or the cheeks are razor sharp). The trickyness is what drives me.

Some examples from a retro gaming event last saturday. All wide open@1/60 with Auto ISO (mostly ISO5000 or ISO6400):

the reason: So let me get this straight...
If I wanted this camera with the evf, the lens hood, a carrying case, and a (needed) 2 stop nd filter Id need 3900$? And some of you are ok with this??!! That borders on brain damage.
Anything you have to compare with a leica M to justify it is ridiculously overpriced to begin with.
I dont care if your 30 year old rollei only did 1/500 of a sec, I care that its 2012 and you wanna charge me that much for 1/2000 of a sec.
It amazes me how hard some of you are trying to justify this thing...

Please show me a camera with a leaf shutter that can go faster than 1/2000s. As far as I know, they don't exist. At all. 1/2000 is crazy fast for this type of shutter.

In reply to:

Shamael: The RX1 had everyone talking. Look at all comments and you get the point. A camera with FF, 35 mm huge lens, 1/2000 fastest speed, in some way a useless wonder in technology. But, there it ends. Let's not talk about the price. In sight of the quality and make of the lens only, the price is rather cheap. But, if Sony had done this with a retractable zoom, in the 20-50 range and a 4000th speed, a 1500$ pricing, this camera had sold like hell. Not to speak about what had been with ILS.

Let us not ask why Sony has gone that way, making a niche product? It will remain a mystery anyway. Let us just hope that it is an announcer for what many of us wait for. If I consider the price of the lens, the RX1 body is worth 5$.

As far as I can tell it's the fastest leaf shutter *ever*. Even Leica's S lenses with built-in leaf shutters don't go faster than 1/1000s. Most leaf shutters max out at 1/500s.

There were reasons to include a leaf shutter instead of a focal plane shutter:
- Silent;
- Flash sync across the whole range (try to find a dSLR with 1/2000s sync);
- The huge rear element of the lens almost touches the sensor, leaving no room for a focal plane shutter.

codeNsnap: Too bad this converter cannot be used with the new X series 14mm f/2.8-

A good converter is an extension of one specific lens design. Generic converters don't offer decent quality.
