Pentax Ricoh Imaging Company Ltd changes its company name to Ricoh Imaging Company Ltd.

The change will be effective from 1 August 2013. Pentax will be brand for all DSLR, interchangable lens cameras and binoculars. Ricoh is brand for compact cameras and new technological innovations.

More and more good news.

If they do which one would be a better buy out of the two for the lens? Will i be able to change the aperture on the lens if i were to use either of these adapters on my GH2? Also, if anyone has a zenith helios or knows anything more about it, please do share with me in terms of video quality.

I know it says M 4/3 but i have had issues with another vintage i had bought with a M42 adapter so i thought its best i cross check with the knowledgeable enthusiasts out here. :) Cheers!

What would be some good lenses? I'm broke as a joke so I'm buying older manual focus lenses.

All this came the need of a friend downgrade a firmware 1.13 to 1.12 In a Pentax K-5 by problems in focus with tungsten light.

I did some research with a Pentax K-7 and its firmware and discovered several things. But the most important and which I think is the cause of the hack of the pentax has not been made possible, I have managed to introduce several ways firmware modified. I'm pretty sure that works in K5, Kx and Kr as well, but I dare say that in older models and new models too like K-30

I want people who have contributed much in this thread, . to renew their illusions. Publish their progress.

The first thing you would need is a good disassembly of any of these models (very similar). I have Ida Pro 5.5, but my knowledge of assembler are rather poor and I can not get to disassemble the code well.

If I can today, will try to test this in a K-5.

I leave you a snapshot of a small text change in the firmware of a K7, which is the model that has left me a friend.

A great

@strancali @driftwood @feha Thanks and following on from the Cluster V6 discussion regarding the Pentax FA31 Ltd.

It is a bit of a gem though it's not exactly cheap. I have a Pentax DSLR system and already had this lens for some two years before I bought the GH2. It's not as sharp as say a Samyang 35 F1.4 is wide open, but it's very good from around F2.5.

However it has great color, bokeh and 'depth' for want of a better term. Yes there are faster lenses, and lenses that are sharper wide open, but the FA31 does have a certain look that I think makes it quite unique and seems to be the reason many like it.

It's around 58mm (35 still frame equivalent) on the GH2 and almost could be considered a 'standard' focal length lens on an Super35 or APS-C video camera.

All three Pentax FA Limited's which include the FA31, FA43 and FA77 come from the film era and while they are screw drive auto-focus they do have proper external focusing rings with hard end points and are probably amongst the best manual focusing auto-focus lenses around. They also have proper aperture rings which can be set to either the 'A' setting for aperture control via a Pentax DSLR or you can manually set the aperture when the lenses are fitted to any other camera such as the GH2. The FA Limiteds take lens gears and operate fine with my follow focus.

If I didn't have any Pentax camera gear and was just looking for lenses for the GH2 would I buy a Pentax FA31 Ltd now? I guess at around $1000 USD you need to ask yourself the question is there another lens(es) that would be more desirable for shooting video on your GH2?

I'm personally quite interested in the Voigtlander 17.5mm F0.95 but only wish I could use it on my Pentax K5 as well.

The other thing is the lighting. I use a Photek Softlighter II with flash for still photography but replace the strobe head with 4 x 85w Spiral Fluro's when shooting video.

Sorry for the long rant but you did ask! ;>)

Here's a still shot taken of the same fellow (but in orange garb) with the FA31 Ltd on my previous Pentax K7 and also using the Photek Softlighter II but with flash rather than fluros. The APS-C sensor of the Pentax means a crop factor of 1.5 versus 1.86 with the GH2. So this is around 46mm equivalent focal length on a Super35 which is more relevant with video being the subject here.

(This was shot about two years ago when his house was much less cluttered!)

Each camera has major strong points...

The GH2, as hacked, is much better for video, but the GH2 has just a few weaknesses, ...all of which are addressed by the addition of the equally cheap Pentax camera.

1.) The K-01 is both a good video and a great stills camera. I much prefer the K-01 for stills.

2.) The K-01 is way better at high iso (video and stills) than the GH2 ...useful when there is no alternative to shooting -in low light: http://forums.dpreview.com/forums/read.asp?forum=1036&message=41548437&changemode=1 http://forums.dpreview.com/forums/read.asp?forum=1036&message=41559032

3.) The K-01 is a fast panning bandit...no rolling shutter issues -likely due to the K-01's internal IS ...and blazing card write speeds.

4.) ALL Pentax lenses, all of them, work great on both cameras. Pentax lenses on GH2/K-01: http://whatblogisthis.blogspot.com/

5.) There are some (selected) shots just better with APS-C size sensors... The IQ can just be so much better!

6.) The faster, newer rendering engine on the K-01 takes full advantage of fast SDXC UHS-1 cards

7.) The K-01 is not a Nikon, Canon, or a Sony!

Looks pretty good.
