Ricoh GR First Impressions
I recommend a universal charger that can also charge most other devices. A bit fiddly to use but the only one I take on holiday for Blackberry, camera, wireless speakers etc. There should be a Chinese version of the filter adaptor and hood kit, for much less £ - I use something similar for my GXR...

Ricoh GR Vs Nikon Coolpix
Although it is a bit of a pain having to order one, as the GR uses the same battery as its predecessors, 3rd party chargers are easily available for a fraction of the (highly inflated) price of the Ricoh one. But even if you order the Ricoh one, the GR still works out cheaper than the Nikon. I al...

Yeah, I guess you know why this happens with this camera... Yes, because of the lack of a Bayer-AA filter. There have been reports that it is quite unlikely that one runs into problems. Therefore I tried to provoke color moiré. https://www.pentaxuser.com/forum/topic/k5-2s-moire-just-for-the-recor...

To be fair, it is a very extreme example in choice of subject. With this image I wonder if you would not see some moire even with an AA filter? To correct it though I would think about converting to black and white, or even shooting in black and white. Have you tried this approach, and if so...

With this image I wonder if you would not see some moire even with an AA filter? So, here we go (similar pattern & conditions): K-3 + FA 20-35 (ISO 100, 20mm, f7.1, distance about 1.2m, AA-Filter-Simulator: OFF, TYPE 1, TYPE 2) http://www.pentaxforums.com/forums/172-pentax-k-3/248432-k-3-aa-fi...

Would be interested in how well Paul's suggestion of using apertures smaller than f10 works to reduce moire (relying on diffraction to create blurring, rather than the SR-based AA-filter-simulator). Cos it sounds like a rather clever idea to me. What f-stop do you need to go to to reduce the moir...

Moiré is less pronounced at small and at big aperture settings. One could use MTF diagrams as a guideline to guess the corresponding f-stops for a specific lens. At open aperture picture quality might not be sufficient. Diffraction also can act as pseudo-AA-filter. However, image quality then al...

GR Musings...
Hey John, I think I mentioned to you that I had two adapters and hoods. I have one fitted with the hood and 49mm filter for the native lens protection and the other fitted to my GW-3. This way I can change both units just like a lens on D-SLR. Jules, as for the GW-3 and its fiddly rubber lens hood...

Interview Ricoh's John Carlson (Pentax)
He remains tight -lipped about future development ... Lets hope their just planning to spring a surprise with FF :D The obvious interpretation of his wafflings about it is that they don't think there's the market for it :( Lets hope its all a cruel trick. One good clear positive message is about...

Ricoh repair guides (GR)
The original plan was to have the GRIII as my sole camera, so I sold up all my gear and bought a new Street Edition. I loved it initially, but even though I'd bought the neat looking Haoge filter adapter with a UV to protect the lens mechanism, the worry of the lens jamming and camera losing value w...

The Nisi Master kit for the Ricoh GRIII
I'd read about Nisi filter kits for the Ricoh GR cameras a few years back, but had been put off by stories of the filter holder dropping off when the lens was retracted (which is quite often in my experience) - the other day I discovered that Nisi offer a filter holder that uses the same fitting as ...

The Nisi Master kit for the Ricoh GRIII
Really useful, thank you, John. As for the images, as usual with your ability to 'see' not just 'look', first rate. Lovely work there, brooding, dark but, as always, the mono really works for me. Thanks Kevin, there was little point trying to capture the scene naturally - it was quite gloomy (even...

The Nisi Master kit for the Ricoh GRIII
Thanks for this. very interesting and nice shots. Any idea if this will fit the original Ricoh GR APS-C please? I'm fairly certain that this kit only officially fits the GRIII (there is a separate version for the GRIIIX) but I have seen references to it being suitable for the GRII but nothing before...

The Nisi Master kit for the Ricoh GRIII
On the question of using the filter kit on a 40.5mm filter end then I assume a step up (or is it step down) ring of 49mm would be what you need :confused: p.s. If you search on the other forum there is a post "Nisi P1 square filter system for Use on a Pentax Q" that might help! Well, seeing a us...

The Nisi Master kit for the Ricoh GRIII
Well, seeing a used GR3 kit at a decent price on the usual auction site, I took the plunge. A step up ring arrived a couple of days ago, the filter kit arrived this afternoon. A very quick check with the Q-S1 confirmed that the filter holder fits OK on Q lenses via the step up ring. There's definite...
