Emadn13: one of the worst focals,come on samyang give us your magic the 85mm

The lens is a Samyang 85mm F1.4 in the Fuji X-mount version. I checked and it is not F1.2.

If you drop the low end to $1000, you can (and probably should, in my opinion) include the Sony A6300. I see now it was included in a recent roundup of cameras in the $800-1200 range. Oops!

It's good to see a new lens of this type that is not simply a copy of Lomo's Petzval.
There must be another ten legacy lens designs nearly lost in the dustbins, and this particular one seems very worthy of a modern refresh!

Marty4650: I think I finally understand how this works.

If a lens really does a bad job at anything..... flare, blur, aberrations, etc... then it becomes a highly desirable "creative tool." And someone will prize it for these characteristics.

And if the original bad lens can be had on ebay for $20, then someone will come along and create a new version of it for $300.

I give Lensbaby a lot of credit for finding this product niche, and milking it for everything it is worth. Seriously, this is capitalism at its finest.

To me it looks like Lensbaby has simply copied Lomo on this one, minus the Lomo exchangeable aperture plates.
I wonder why, when there are hundreds of vintage lens designs, they had to copy Lomo.

jkrumm: Looks like it would come in handy for a dermatologist, especially combined with the A7RII.

I was thinking dentist, for remote dental exams on whoever might be the latest celebrity.
Looks like Sony has the world's best lenses now.

Your Sigma lenses should have held together better.

ZhanMInG12: The ergonomics is quite inexplicable. The EVF is not only not on center but also not in a place where either eye can use it comfortably. And if you're not going with an articulate screen anyways, why not put the iso button on the screen's right side? And then there's the bottom...

But I suppose this is Sigma, and they have a tradition of weird designs. I'd buy it - if it came in E-mount.

Looks like the SD1 grip is living on, in the new cameras. Personally I like the Quattro design, but that SD1 grip was perfect for me and I can't forget it.

In reply to:

Marc Ramirez: I like the design. Battery grip looks cool too. It should really have different mounts, m43, E, etc. Especially since sigma is now in the adapter game.

Maybe this is going to give them enough time to come up with a really good shallow mirrorless mount, in the next couple years.

Mssimo: The biggest issue with sigma is support for RAW files. Last time I used sigma RAW converter it was a nightmare. Crashing, taking 15 secs to refresh after making a simple exposure adjustment and so on. If they could only work with adobe or another company to get raw support in third-party software.

And it will most likely remain a niche because the sensor itself is profoundly different from any color filter array (CFA) alternative. This is a mathematical enigma, solved every time a Foveon camera takes an image. It is very intensive and will always run slowly compared to CFA, no matter how advanced the processors get.

AkashRana: I never quiet understood Sigma SA-mount cameras, and their foveon sensors; which are presumed to be so great but i see no adopters for those sensors. Still bayer rocks the world

Foveon is a different animal. Most people won't like it. Hence the popularity of the iPhone 5 camera.

I hope DPR will review at least one of these.

On article The long, difficult road to Pentax full-frame (617 comments in total)

Really well-written article with great legendary imagery!

Pentax might interest its existing medium format owners by offering adapters so their MF lenses can be used on the K-1, lenses such as
HD Pentax-D FA645 35mm F3.5 AL [IF].

While not cheap, these lenses could work very well on the K-1 and they are already in the Pentax product line.

If this camera is going to have a Sony sensor, is there any chance it will be the sony FF BSI as found now in the A7RII?
Pentax might be bringing a Sony sensor (of any size) to the market in this camera but hopefully they will bring it in a more photographer-friendly minimum-fiddle durable body. They can sell a lot of Sony sensors this way so why not sell it with the best available sensor at the moment?

In 2016, please think more about selling expansion capacity in the DPR galleries. I'm sure I'm not the only one who would like a bigger space.
Also, the format of the newer photo sample galleries really wants to have a high bandwidth connection. I miss the option to download and view a "large" version of random sample photos.

The Sigma SD1M comes with a removable IR filter. No political correctness here; just a little flick of the fingernail and the filter is removed (and the very fragile IR filter is just as easily re-installed).
I've seen full-spectrum photos on the Sigma forum here at DPR, and am not impressed, but that's just me not being into the art.
There is a whole IR subculture using these cameras without the IR filter; maybe 10-20 people in the Sigma forum.

Fujifilm sells an infrared-capable X-T1 through B&H. So maybe Ricoh will slightly change their marketing strategy in the future.

If Samsung has allowed Sony to take over, we are all the losers. Sony's strong push into the upper reaches of sensor design seems to be dominating the markets at this point, whether in Sony cameras or other brands.
So we have one fewer sensor manufacturer out there, and fewer choices for our art.
Even with my Fuji system I am supporting Sony, who has built the basic sensor my Fujis use. Same for many other brands.

What kind of shutter? Is it focal plane or leaf?
