Another interesting announcement... Too bad they kept the slr mount: Surprise! Sigma announces the Sigma SD Quattro and SD Quattro H SA mount mirrorless cameras! – mirrorlessrumors Specifications | sd Quattro | Cameras | The Sigma Quattro SD: Two mode Autofocus system Mirrorless system, Dust & Splash magnesium alloy body Resolution equal to 39MP Bayer sensor on resolution testing Compact design similar to dp Quattro cameras SA mount The Sigma SD Quattro H: Larger APS-H sensor Resolution equal to 51MP Bayer sensor on resolution testing Designed to take advantage of SGV lenses with great IQ SA mount {} {} {}
has the imaging pipeline been beefed up..... operational speed improved upon...... software made better? I love the images from that Foveon sensor, but I won't work with the wonky software or slow cameras.
Looks like the work of a product designer that's not a photographer. The moment my right pinky dangled below the grip I'd throw it against the wall. [breathe] ...maybe I should cut down on my coffee intake...
If bad design (although I admit that my pinky rests below the grip on every camera I use) doesn't make you angry, then you don't care enough. I think your coffee intake is fine.
Luke, I would hope they fixed the operational speed seeing thats it is a bit bigger than the fixed lens ones, if not it doesn't make much sense to me. I'm curious to see if they've improved the high ISO any.
very exciting to me as it gets closer to bringing foveon to the masses. they not only made the camera splash and dust proof, but the lens mount itself is protected. and theyve implemented focus peaking for manual focus lovers. as long as theres no shutter lag i'm less concerned about 'operational' speed than i am low light performance. the pity to me is that i believe the SA mount has legacy glass compatibility limited to m42 mount lenses, though i'm happy to be told i'm wrong on this. and the evf placement may prove to be a bit difficult for some. but i am really anxious to learn more.
I would love to have a Foveon camera again and this got me excited. Then I opened the pictures above in Photoshop and used the hotshoe to get an idea of the size...suddenly I remember why I sold my Canon 7D a few years ago
Sigmas are not famous for their af/operation speed, so adapting mf lenses make sense. Sigma SA has the same flange distance as Canon EF, so all mf Contax/Nikon/m42 lenses are adaptable to Sigma. However IQ is the big question as one pro photographer at FM forum is saying he had color shift issues when he adapted the Contax 85mm lens on SD1... And another post about Nikon mount Zeiss lenses on SD1: Sigma SD Quattro with SA mount. A mistake?: Sigma Camera Talk Forum: Digital Photography Review Another poster from the same dpr link:
So Sigma have designed a "true" mirrorless camera - a DSLR with the mirror and prism removed. Nearly everything else is still a converted film camera - size, weight, lens mount. So a useless spacer tube to take film camera lenses and their later DSLR counterparts. A mount that takes 135/FX lenses needlessly. Which is also why I never use the term "mirrorless" but follow the original naming convention (SLR, DSLR) and call my X-T1 an "SLE"" - Single Lens Electronic viewfinder - because its design is such from the ground up and owes nothing to having once accommodated film (mirror, m1rrobox, pentaprism reflex finder, light-tight film enclosure).
