Yeah, I don't think manual focus is really for me, except in limited cases.
Ditto. It's pretty hard doing manual focus with the SamYang 85/1.4, especially in poor light. A 50/1.2 would be just as awkward. When you have a camera that has an AF system as sensitive as the K-3's, not putting it to use driving modern fast glass seems a waste.

Gotta disagree. There is a ton of vintage glass that is just as good as, if not better than even top-end modern glass, plus there are tons of length/aperture combos that simply aren't represented on any platform.

As far as super-fast glass goes, In my experience with 50mm f/1.2, having used both several manuals and the Canon EF 50mm f/1.2L, when your DOF is that shallow, it's a crapshoot as to whether it will focus on the point you want it to focus on when using AF, even with Canon's much smaller AF points. MF has far better control in critical focusing situations, particularly with portraiture, where it is essential to have the eyes in focus.

If anything, I'd think the ideal solution would be MF with in-body focus peaking. Here's hoping that the peaking feature in the next generation of Pentax DSLRs catches up to their competitors', since right now it is pretty abysmal.

The rumoured Samyang 50mm lens is designed for system cameras (mirrorless), not DSLRs.

I prefer autofocus to out-of-focus

Hmm. Canon's much smaller AF points... Do you have a K-3? The focus point density of the K-3 seems little different to any current Canon:
K-3

70D

1Dx


And focus peaking, as well as Live View generally, works a treat on the K-3.

The problem I have with MF and fast f1.4 lenses is not in using them for studio shoots with good lighting, but in [ab]using them for live music shoots and general event shooting in low-light interiors. There's often very little visible contrast in the viewfinder, and the subject is often moving around a lot. It can be done with manual focus, but decent AF would makes it easier and probably improve the keeper rate substantially. Much as I like my Rokinon 85, I've been thinking of replacing it with a Sigma 85 or FA 77 for just that reason.

Say some:

Samyang to launch a high quality (and low price) 50mm f/1.5 lens for "some" mirrorless systems. | Mirrorless Rumors

(FT5) Samyang to launch a 50mm f/1.5 Micro Four Thirds lens at Photokina. | 43 Rumors

whilst nobody, neither Photo Rumors nor Samyang ("Our R&D team is working hard to release a 50mm lens very soon.") says it's a DSLR lens.

You've apparently never used Canon's or Sony's focus peaking if you think the K-3's is good. In the (admittedly limited) testing I've done on the K-3, it is borderline useless compared to the competitors' which are much more accurate and use easier to see peaking colors. Ditto for the Q and K-01.

As far as the focus points go, basing it on the schematic point density illustrations used in camera manuals is more than a bit silly, since they are not a one for one representation of size but rather merely illustrate the placement of points. Remember, density and size are two different things. And even keeping that in mind, the illustration for the 1Dx shows significantly more center focus points (within the central circle) than does the K-3. Granted, that's a full frame body, but even taking the increased frame size into account, the point density across the frame appears higher.

FWIW, the official review on the K-3 here, when it was announced, indicated that the AF points, while greater in number, were the same size as the K-5's, and some users have reported that the K-5II AF actually performs better in low light than does the K-3. The original K-5, of course, was a bit of a mess, particularly under Tungsten.

While I generally agree with your premise that AF could be helpful for low light action in some settings, again the extremely shallow DOF would mean that your subject would have to be pretty far away to be completely in focus wide open, which in many cases (say shooting in a theatre from far away) would mean that for most shots, you'd simply set the focus once and shoot away. In these sorts of situations, a 50mm f/1.2 is not necessarily a great lens, even with AF, since you have to get to a very wide shot before you can get a good DOF wide open. For musician closeups from the edge of the stage, you are going to run into the same problems you do with portraits. Yeah, you can close down the aperture, but then what's the point of having the 1.2 in the first place? If there is a FF released at Photokina, then you'll get a lot more mileage out of investing in the higher-sensitivity body than you will of another $1k lens.

Do any Canon DSLRs have focus peaking? If so, I might want one :-) Even the Magic Lantern cardware won't work with the bodies I have. I was under the impression only their camcorder had it.

They could be developing two different 50mm lenses couldn't they. There is no reason to say this is the lens they meant on photorumors. So there is no reason for you to be so certain about it.

Come on people testing those Pentax cameras - Leak some damn photos under other pseudo names. Next we will have news about "Leaked images"!

Lets do it!

P.S. I am testing a full frame Pentax K-1 with ISO 300,000 and Leaf Shutter. It also has the "Movie Button" and "Swivel Screen". Camera has NFC/wifi/blue tooth. 51 AF points with 39 Cross type AF points. 11 Frames per second. Camera will be launched with a K-mount converter for full frame lenses (So people who don't want to get rid of their vintage glass can use the new system WITHOUT Vignetting). Flash Sync speed of 1/500. Processor SAFOX XXX AFZ M D N TLD module. 30 Mega Pixels. Built in Full-Tether using USB 3.0 / HDMI and Wifi with native support to Lightroom and Adobe Camera Raw.

P.P.S The camera will be designed to take X-Ray of previous dead presidents and their ghosts.
AND, it comes in more two-tone color patterns than a 50's Chevy Impala.

ML definitely has it, not sure about the stock firmware, since I never used it, but you could be right about that! If not, it's kinda strange, since their implementation on camcorders is the best I've used. Even better than the Sony SLRs/MILCs.

I was nosing around on a primarily Canikon forum and that is where I learned A) Canon DLSR's don't have focus peaking, B) Magic Lantern cardware has lots of features geared mostly toward video but has focus peeking, zebras, etc for DSLR's and C) the 40D and 5D original I have, and the 70D I was contemplating, don't support Magic Lantern :-(
