Is this how they manufacture pancake lenses?

jnd: For static scenes the pixel shift is great. People say also for landscapes but with that amount of detail what about moving leaves, waves and reflections in water and such? How fast does it capture during pixel shift?

ISO 6400 in pixel shift mode looks so smooth compared to standard shutter, it's like magic, great improvement.

I have the K-3 II and the pixel shift there takes just 4x the exposure time, logical since it captures 4 images. The stitching then takes somewhere around 3 second to complete.

This is very good news for Pentax, but ever since the original K-5 they have been very successful in the Dynamic Range area. It is one of the few things I'm most concerned about, how well the picture holds up when pushing it. Often bringing details back in harsh shadows to give the look I'm after.

Petroglyph: Ricoh is supposed to unveil a new lens road map at CP+ next week. That should be interesting. Like to see some DFA* primes on there.

Would be interesting with a new super-wide FA Ltd! The concept of the Limiteds are to be somewhat compact, so for an ultra-wide they would have to go small aperture. I think that would be alright by many, as an alternative to say the good but huge Sigma Art-lenses.

On article Worth the wait? A look inside the Pentax K-1 (651 comments in total)

The DA Lens compatibility chart from Ricoh seems very conservative. There are threads on Pentaxforums where multiple users are reporting in test shots with these lenses on film- or Sony A7-bodies, and e.g. DA40 Ltd, DA50/1.8, DA*55/1.4, DA70 Ltd are reported as "Fully functional".

It could be that the K-1's image stabilization moves the sensor quite a bit perhaps?

In reply to:

forpetessake: Pentax FF -- cool! But where are the lenses? All the modern Pentax lenses are APS-C, and all the film era ones won't look too good on a high-res digital with their soft corners, SA, CA, etc.

Many of the "DA" lenses are based on old FF lens designs, there are several threads discussing and presenting compatibility lists for "APS-C" lenses for use on full frame. In general normal and telephoto primes will work, while zooms or wide angles won't.

So the D810A is a consumer camera? In that case why not count the Pentax 645D IR? Larger sensor ;)

Good Job... Bravo Sony !!! :)

don't forget to implement into A7II menu a " User List of Manual Lenses "
-1 Manual Lens Number #1 - #12
-2 Lens Name : useful for Exif Data
-3 Focal Length : useful for Exif Data and IBIS !
-4 Max Aperture : useful for Exif Data

each time the Power-up process doesn't detect any Lens mounted...
... then ask for an entry in this User List !

thanx Sony ! ;)

That is very helpful, much like Pentax has done. On the K-3, K-01 or Q it will ask for the focal length of the lens when it is not detecting, just like you described (you can't name it or set max. aperture, but focal length helps for IBIS and identifying in post). It will also remember your latest focal lengths.

Panasonic on the other hand doesn't offer this, the other manufacturer I have experience with.

On article Integrating the Apple MacBook Air into a pro workflow (346 comments in total)
In reply to:

DonThomaso: A very good alternative if you don't want a MacBook Air is the Sony Vaio Pro 11/13-range. I recently bought a 11-inch (a nice Panasonic IPS 1920x1080 display) with 8 GB RAM and 256 GB SSD for €850. Best of all - magnesium body and weighing in at 0,87 kg! That's portable! I do most of my work on a desktop, else I would have considered the 13-inch.

You can spec both the 11 and 13 inch with i7/8 GB/512 GB SSD, at least in Sweden. Like I said my main worry was reports of unreliable wifi but my experience is that it works perfect (at home, in school, or via hotspot on the phone). I bought mine 2 months ago, most reviews are from the summer when they where released. It may have been a problem then, but it seems like they sorted it out.

I don't know if it is 8 or 10 bit unfortunately. I bought it from Sony Online and then you can specify the components (up to Core i7, 512 GB SSD). Most importantly it is around 2/3 the price for a comparable Air specification. Thunderbolt, Wireless AC or a faster integrated graphics wouldn't have been very useful to me. I wanted light, portable, decent screen. Only worry was reports of unstable wi-fi, but it works just fine for me. Could have been early driver issues.
I wasn't looking at the Air at all really, the display is just too bad. A MacBook Pro 13 Retina seems like a much better choice if you want to spend that kind of money.

Paphios: The yellow K-01 is my bad neighborhood camera. Even potential muggers have doubts about stealing it.

I just spent a weekend in Zürich with the K-01 and three Limited primes (15/40/70). Perfect camera for the job if you ask me, glad I didn't bother with the DSLR.

On article Just Posted: Pentax Q7 Real-world Samples Gallery (136 comments in total)
In reply to:

marike6: Colors look similar to the original Q, but it looks like per-pixel sharpness is a bit better. This is going to be one of the more fun small cameras around.

Unfortunately their best and brightest lens, the 8.5 f/1.9 seems to have been discontinued, and the Q system without that lens is not as interesting. That means, no bright prime, and no OVF (which was designed for use with that lens).

The 01 prime was never supposed to be sold separately, but only with bodies. The ones that has been listed are usually "split boxes". The OVF is for sale separately at the larger stores.

In reply to:

BingoCharlie: Do note that it's not stabilized. Not a huge issue at these focal lengths, but something to consider.

It will be if you use it on Sony or Pentax bodies.

In reply to:

klavrack: BTW, unless I missed it, this story doesn't mention that both models have focus peaking, which, together with IBIS and green button metering, makes macro shooting and use of old manual focus lenses very nice. I picked up a cheap K-01 with focus peaking awhile back and love it with a classic Vivitar 105mm Series II macro lens.

All cameras based on the 'Prime M' processor has come with focus peaking (K-01, K-30) so I would assume that these two also will.

A lot of complaining in the article about how difficult it was. It didn't sound too difficult, it just sounded that he should have bought a Point & Shoot instead and skipped the learning something new part.

Makes me think of the "Kore Ja Nai" versions of the K-x and K-r cameras :)

In reply to:

iae aa eia: I wonder why they (and other makers) don't make a 43 mm (though I don't remember now but I guess there is somewhere [recently launched]) pancake, as this is the truly "normal" lens in FF format. It's always a bit more (50), a bit less, but never THAT.

I also wonder why no maker try hard to make lenses for APS-C with larger apertures, since they're aimed to a class of camera supposedly not expected to have such high demand for quality than FF, thus not requiring such compromises to keep apertures down in favor of extreme quality.

I guess that you are thinking about the "Pentax-FA 43mm F1.9 Limited", which is just that - a full frame pancake lens, released in 1997 (designed for film) but still in production. The actually made it in Leica M-mount (super rare) as well!

Link | Posted on Jun 8, 2012 at 15:16 UTC

I understand why people have pre-ordered the 40mm pancake! If I were a Canon user, I would probably do the same.

As a owner of a K-5 and the 40mm pancake, I can say that it is my most used lens. Optically I assume the Canon pancake would be very similar to the Pentax 40mm, and it is great! The focal length works better than you might think on APS-C, but to use it on a full-frame would be even better.

I'm happy for the Canon users, and hopefully this may bring some attention to the lovely Pentax Limiteds :)

In reply to:

vastoulis: " If you haven't been following along, that's a K-mount in the picture, and it supports virtually every Pentax lens ever made."
EVERY Pentax lens???
Are we to assume that the 42X...something (don't remember the pitch) screw thread lenses were NOT made by Pentax? (OK, I'll admit they were made by other manufacturers as well but, I seem to recall that the mount in question was called 42mmm Pentax Thread)
DAMN, this stuff makes me feel old!!!!!

If you distinguish between "natively support" and just "support", the statement may feel more correct.
K-mount and M42 has the same flange focal distance, so a simple and small adapter will do. Also medium format (645/67) lenses will fit, but with bulky adapters.
Lenses not supported will then be Auto 110 and the new Q-mount lenses.
In this interpretation of support, all of the other mirrorless cameras has better support for old glass, so I'm not really sure what to make of the statement. The main point for me (if I were to buy a K-01) would definitely be in body auto-focus support for the K-mount lenses.
