I'm about to go the same route, I'm picking up a Pentax K-5 iis next week, my first film camera was a Ricoh. S

A friend of mine who is my photography mentor has a K-5 and he loves it. The K-5II is even better.   He almost talked me into getting a K-3 and I am not sure I made the right decision in not getting it.

I haven't bought the K3 (yet), but it looks to be a better performer for AWB and metering than previous Pentax bodies.
I use K52s, K30, K10 and I find the metering is often quite different from every other mfr body I use, and often in a way I find inconsistent and less predictable to compensate.  So I waste a lot more time chimping my histograms with Pentax than with other brands. Even then, and even when using full manual, I find I often need to tweak a bit in post.
When nailed, the IQ is excellent, so I've generally only used them for non-action work where I can re-shoot as needed.
Pentax lenses are another odd thing compared to others; their test results are usually not very impressive but the resulting images are generally pleasing. 
Pentax users are often quite avid about their equipment and I can often see why from the results I've obtained with my gear. (Tho I'm wondering about the results I'd get using a Sony A72 with K-mount adapter instead)

I find I can achieve a similar enough effect, with more consistency and less color-shift, in post.
I only use a polarizing filter when I need to kill specific reflection issues but even then, things can be done in post.
It's my least-used filter.

I think the guy is just too lazy to get the flash off his camera, set up properly, or fix anything in post.

shot #17 from this batch

... is just a lesson on how to make an unattractive shot of an attractive model. The rest of the set is sub-par too.
The few other 'togs who do these shoots do a FAR better job of lighting than this ego-maniac.

IMO, JACK BOLAND, your lighting technique blows chunks.

maybe some little boxing-glove icons could be added in there too, for adversarial and combative posters. ;)

NOW we're getting somewhere!  A machine like this will temp even me to try out a Sony body... with lots of lens adapters.

translated at SAR forum:

for those who haven't experienced IBIS in a Pentax or Olympus body, it can work very well.  Makes nearly every lens you have stabilized, even classic old primes.

This is a product I wish Ricoh-Pentax would have put out... 2 years ago.

Higher-end A-9 model still rumored for early 2015,  Hmmm...

EOS Bodies / Re: Canon 7D II sensor measurement

The best page on the 7D Mark II sensor comes from

It is clear from this that Canon still hasn't resolved the high read noise at ISO 100 - 800.
their current system architecture has too many compromises to accomplish that.
But canon users can be happy that they've at least they've finally knocked FPN way down and hopefully that will also become an improvement across their whole range of SLR bodies.

any chance someone was breathing a bit heavy near your camera and fogged the lens a little bit? ;)
kinda looks like a mild case of condensation

Here's another series of screenshots from Iridient Developer, v3 beta.

These are 25% linear scale of the black-cap-shots which give an impression of what the raw files are like when pushed even harder so you can better see the residual horizontal and vertical banding structures.

Files are saved as jpg with 4-4-4 subsampling to better preserve the speckle appearance which 4-2-2 otherwise smears.  hopefully that doesn't get messed up when uploaded here.

These are pushed FIVE stops.
Then another has +100 Fill Light added
Deep Shadow Fine Tune has NO tint correction applied

done for both 100 and 1600 Iso

one 1600 iso is pushed 5 stops, no fill light, and then Deep Shadow Tint-Correction is set to low.  Notice how it does a nice job of removed most of the red noise speckle.  No idea how well this would translate to shadow detail loss, however.  Perhaps someone can try that and post the results.

The file names are 7d2_iso-EV-fillLight-444.jpg

EDIT - just checked full size image recovered from clicking on the sample here and it's pretty much what it should look like.

Lenses / Re: Is the new 100-400L II going to be a push/pull after all?

I'm sure there should be some precautionary note about not pointing at the sun too long...

I don't know about your lenses or shooting circumstances, but for me lifting the +0.5lv af limit of the 60d (that's not very dark esp. with f4+ lenses) is a merit on its own.

FWIW, I measured +0.1 EV with my Sekonic 558 on an indoor target i was using for some tests.
with the 100-400 L mounted and stroked out to the 400mm end, the 60D and the 7d2 were both able to AF, and oddly, the 60D did it subjectively faster every time.
I think there may be some minor issues the 7d2 needs to have addressed with some firmware tweaks.
I'm pretty sure 7d2 would deliver better IQ than the good old, non-ML-equipped, 60D.

But it is a grower
hopefully also a show-er

In the spirit of our under exposed sunset theme I gave one of my Alde boat pictures a darker curve and then brushed back the boats.

I think it has improved it actually.

+1, slightly increases the color saturation in areas which is subjectively pleasant.

Hmm, talk about opposite of the design brief use.

not entirely, even motion and tracking AF has to start somewhere.
Another thread or two on the site are discussing the same AF lag issues i experienced.
Compared to my other bodies, this lag is sometimes so long that I'm wondering if I pressed the button!
In the time other bodies give me a confirmation beep, the 7d2 is only just starting to move the lens.  This is not good.

What auto focus issues?? I am sure the best thing about the camera will the AF!

I'm expecting it to be the king of AF too...  but some of us have noticed a rather laggard AF response, at least with certain lenses.  I've also found 7d2 to exhibit some inconsistent AF performance at times, enough to be both puzzling and disappointing.  Hopefully it's a firmware fixable thing.  As it is, with the lenses I want to use, it's no better at AF than my 60D.  I'm sure it would track motion better, but for static, center AF point, it's not been impressive .. yet.

EOS Bodies / Re: Canon 7D Mark II - Finally using Canon's newer fab?

Maybe it's just from the CFA filter having been made even more color blind.

The low color measurement on DxOmark does seem to indicate they may have picked up a little QE from a looser CFA.
