Surely the latest Lightroom has lens profiles for the Samyang?
Is there any major functional reason why these lenses couldn't still be used for still photography?
I assume that there are no auto-diaphragms in these lenses? ( OK, I just read that the apertures are decoupled)
Ayoh: Looks like it might do video judging by the Mic and Speaker holes visible on the left side of the body
And the new zoom has built in stabilization too looking at the switches
Should be a really impressive piece of kit, and 1/2-1/3 the cost of the competition.
"The (infamous) Green Button" on Pentax cameras is used for programable functions so perhaps video might be one of them with this camera.
On a K-5 one of the uses of "The Green Button" is to set auto-exposure in manual mode and, by pressing AE-L, you can then use a command wheel to adjust shutter or aperture with exposure locked. Pretty useful.
bossa: I was hoping for a mirrorless version to get the size down to a D800 or D4 but they've stuck to the previous format.
I have two D800E's but would consider selling for one of the new 645D's and a couple of lenses. I find my photographic needs have changed somewhat over the past couple of years and a 645D MkII might fit the bill nicely if it comes in at the old price.
bossa: DA*300mm is a FF lens as is the DA*200, DA*55 and a number of other DA lenses. The fact this converter is listed as 35mm FF may auger well for a Pentax FF camera in the near future.
DA*200 is in fact the FA*200 in a new outfit and it has been shown on PF that the other lenses I mentioned are indeed FF (as in they cover the image circle). They may not be telecentric re' FF though.
PS: I don't have to twist anything as I have two D800E's.

thx1138: $600 for a freakin' 1.4x TC is ridiculous. Street price needs to be half that.
My Nikon TC-14E II cost AU$645 and that's a ripoff when you consider grey imports are 1/2 that price.
SungiBr: I've had the Tamron 1,4x PZ-AF MC-4 converter that have a power zoom contact and those worked perfect with SDM and DC lenses, with almost zero penaulty on quality. But don't understand the need of a firmware upgrade in order to use it. Could it be the camera will recognize the TC and do proper adjustments in SR?
Probably gets the camera to display the "new" lens focal length when the converter is attached. I used to have the same Tamron TC and it always displayed the original lens FL in exif data. I found my DA*200 lens worked very well with that converter.

ThSpeer: Is there a comparison with the previous Sigma 120-300mm f/2.8 AF APO EX DG OS HSM , which was released just a year or two before the current 120-300mm F2.8 DG OS HSM ?
One of the elements in the new lens has a different type of glass and that's what is improving the image quality.
ekaton: And the recipe is: pets, small children and lots of photoshop - and many will like all these real life shots. Not my cup of tea. Too obvious an exercise to push the "uuuhhhh oooohhhh how sweet grandmother buttons". By the way the world we are living in these days, at least in some parts of it, would probably react very differently if the very same pics were taken by a man.
Juxtaposing a kid with a fluffy animal, and using thin DOF to create decorative backgrounds has nothing to do with serious art. The pictures exhibited here seem very staged, kids with fixed gazes staring into space, no joy, no fun, no expressive play, no emotion and no action.
People here are getting caught up in the cute subject matter, the thin DOF and the decorative bokeh. Never mind existential issues about childhood and the future.. etc
It helps to read a few art books if you would like to develop your sensibility. Hanging around forums isn't an art education.
The 1st dog shot has a dark 'halo' affect around the dog indicating excessive PP.. etc etc..
If these things don't matter to you or you cannot see them then so be it.
bossa: Kiddies with animals have been an ol' fav' for generations. These pictures are, predominantly, set pieces that are designed to appeal to sentimental parental instincts... ..cute isn't necessarily good art. The genre of the work is reminiscent of kitsch paintings from the late 19th to early 20th century and, from my perspective, is very boring in every way.
Seeing as I have a masters degree in fine art I don't need "cluening" to explain to me what art is.
A typical response oldman55. One doesn't need to be anything but an observer to understand and make a critique. By your statement people would have to submit their work for validation in order to make any kind of statement, not just a "negative". Why would anyone seek authorization from someone they are trying to enlighten? In order to win an argument you don't give your power away.

wb2trf: What a dumb review. There are a few reasonable criticisms, but there is this overall tone of snarkyness that is merely a gloss on stupidity. Start here: "despite the best efforts of Sony's UX designers to bury the relevant option at the end of page three in the custom setting tab of the menu setting. 'Release w/o Lens: Enable'" Now lets think for one minute. Since every option has to go somewhere something must be at the bottom. Since there is never a need to reverse this decision, you literally set it once for the life of the camera, where should it be? At the bottom of course.Next, we have the crazy complaints in the paragraph that begins, "I can't remember the last time I used shutter priority (I'm an aperture priority kind of guy)" This paragraph is completely idiotic in its entirety. He writes as if he is disappointed that aperture priority isn't useful. Of course not! Secondly the choice of 1/60th can't be "biased in firmware" as there is no information to use. Dumb.
All SMC-Pentax "A" lenses have an "A" setting on the aperture ring, which, when set, allows all the latest Pentax cameras to set the aperture and makes Aperture Priority mode "useful". Does the Sony have anything like that function? I'm guessing "no" by the way people are speaking about it.
RStyga: A7 is a groundbreaking product in terms of compactness to IQ ratio. It is ideal for using very small lenses, either FE mount or other 'compact-lens' mount such as Leica M39/M.The problem is that adapters come at a rather significant IQ cost in the lens periphery due to manufacturing tolerances (http://www.dpreview.com/news/2013/09/30/roger-cicala-investigates-accuracy-of-lens-adapters) and compact FE lenses are not yet available (except for the 35/2). Also, when compact FE lenses become available they will probably be very expensive (so much for touting an inexpensive camera body), judging from the price of the 35/2.So, A7, as a camera, is great (save some ergonomics and construction quality issues) but, as a system, the jury is still out.
That sounds a lot like my current GF ;)
I can attest that the Pentax 40mm is pin sharp wide-open, unlike the DX0 Mark test results show. I cannot understand how DX0 Mark continually gets substandard test scores for Pentax lenses. Lenstip scores the DA*55 at almost 50 lpmm, one of the sharpest 50's they've tested and yet DX0 Mark gets different scores.
Another site has the canon and Pentax 40mm on about even pegging re' resolution but the Pentax has better CA but worse in the Bokeh department.
bossa: MTF graphs of the new lens show a lot of astigmatism compared to the older lens but higher resolution. The Bokeh will, most likely, be nervous where trees and shrubs are in the frame.
I was thinking of selling my current Sigma 50 as a preemptive measure but will hang on to it for now.
The MTF scores are also a tad lower than the Otus and so it will be an interesting time when comparison tests start to show up.
@ zaakirabdullah: You should qualify that response to my post if you can? I dare you to actually say something of value.

beholder3: So you get "silver" awards and 84% for:- unreliable autofocus (" no way of persuading the lens to focus accurately at all")- poor sharpness at the aperture it is mainly selling for("anything but sharp wide open, giving rather soft, low-contrast images")- overpriced / poor value for the money ("Very expensive")?
The three key factors suck. Not even mediocre.
Makes me think the "silver" is the silver dollars offered by Nikon / the Amazon gear shop to smoothen these review results for allowing good sales figures.
The 50/1.4G was a piece of junk that I couldn't get rid of fast enough.. low contrast all through the f-stops. I don't know how Nikon can live with themselves peddling junk like that and the new 58mm.
The point I'm trying to make is that these lens testing sites get way to much variance in their results and conclusions (possibly influenced by financial arrangements) and so, IMO, you're better off trying the lenses for yourself.
If you can't afford an Otus then buy a Sigma (which is really a 47mm lens anyway so you can be excused for having both)
I've had two Sigma 50/1.4's for my D800E's but foolishly sold #1 for the Nikon 50/1.4G. I couldn't get rid of the Nikon fast enough after realizing what I'd done.
I owned a Sigma 50/1.4 for my K-5 & still own a Pentax DA*55/1.4. From my experience the Pentax lens clearly beats the others wide open - DX0 Mark has it being very poor in their tests results - Lenstip has the DA*55 almost equal to the Otus in resoltution tests from F2.8 - @ f/4 & f/5.6 it's razor sharp.
Bokeh of the Sigma is wonderful wide-open whereas the Pentax is a tad nervous. The DA*55 gets real smooth after a couple of stops though and is sharper at f/1.4 than the Nikon is at f/2. At almost 50 lp/mm by f/4 it's one of the sharpest 50mm lenses I've used.
