Most Japanese equipment uses JIS cross heads. The A series
seem to be them, but the 35mm M series lens is a perfect
fit for the tip of a PZ0. I've since replaced the screwdriver
(Teng Tools are excellent) for about a fiver off ebay, but don't
fancy breaking another one. I may try a soldering iron on it
sometime the lens is just a paperweight at present, but I have
other 35mm lenses inc. the K 35mm f/3.5 and the DA.

You don't need the adapter just Dremel a bit off the lens
mount!

Hard to believe that lens came from the same factory
as the Tomiokas

Nice CZ 55mm f/1.2 only £5,580 can be adapted to Pentax

ebay

If you see any Leicas in the sales for 1/6th of their
usual price let me know

The f/1.2 on ebay is the same as one I've got. It's quite a
good lens and is a K mount. I've also got the M42 Chinon
Tomioka (labeled) one and the Pentax K 50mm f/1.2.

The one similar to the ebay one is the easiest to focus and
might be the sharpest wide open, but only just.

They are quite handy lenses, quite a few of the shots on
Flickriver were taken with K-5's and K20D's and show that
current cameras are up to the job.

Sadly you need at least a Half-Plate Camera to get
portrait quality DOF Plate_camera_portrait

They must have had punters queuing up for a demo if they
needed 10 Without lenses as well??

That's about the price of a SH K10D

Very silly putting a 40mm lens with it.... 60mm on
35mm only any use for portraits No wonder
they didn't sell.

I think SRS are selling K-01 bodies for £219 and Q bodies for £99.
This is happening worldwide and Pentax must be losing a lot of money
on them, plus the losses due to early problems with the K-5 and the
only cameras they have in the Japanese top 80 are the Q's due to
low price. These were asked for wordwide by the Pentax community,
they wouldn't make things if the market didn't look like it
wanted them.

They need something profitable very quickly. Strangely the
Q10 seems to be their best bet.

You lose a stop due to DOF so if you want the same DOF from the
APS-C as the FF you open up to f/4 which gives you the advantage
of an extra stop on the speed making it 1/15th second instead of
1/8.... that would be better from a handholding POV.

If it was a group shot the larger DOF of the APS-C would be handy.

There isn't much interest in shallow DOF's so it's hardly a reason
for going FF. This lens hasn't sold and it's been through a few
times looks OK to me and the price is low.... very nice bokeh and
much cheaper than a FF camera.

It would give you the effect of an extra stop on the aperture side
in DOF terms as long as you move in closer which might make the
subject uneasy.

I don't think most people would notice f/2.8 looks very similar
to f/4 and I haven't heard anyone saying that they want a 35mm f/1.4
or f/2 they even seem happy with the 35mm f/2.4 lens.

If I were photographing say wedding groups I wouldn't want
extra DOF which could mean some people were OOF so APS-C
would be preferable.

It's not beginners who are calling out for a FF camera which
if they ever produce it will probably mean the end of Pentax
so it's quite a serious matter. The people calling for this
camera SHOULD know about DOF

The DOF stuff I've mentioned here would have been known by
children on a school photography course a few years ago and
I'm surprised that no one calling out for a FF camera seems
to know anything about it.

It wasn't beginners either who wanted a mirrorless camera
which when eventually produced in the form of the K-01, they
then decided that it wasn't such a good idea after all and
kept the money in their pockets. It will be the same with
the 560mm lens... ask for it... it gets made.... people
won't/don't want to pay for it

I've all the time in the world for beginners. I've
directed them to some very good tutorial videos in this
thread which a few years ago they would have to buy.

I can't see why you feel the need to start an argument,
your time would be better spent also sharing knowledge.
