1) HIGH PRIORITY Complete NR OFF switch. It seems that the GRDII NR OFF switch does not actually turn the NR completely OFF. It only make the NR less aggressive. However, with respect to original GRD grain, the GRDII noise reduction is way too aggressive. It would be ideal if there would be another option in GRDII menu, which will allow the advanced users to turn the NR completely OFF.
The available options may be like this:
OFF - an option, to turn the NR completely OFF (the same amount of noise as in RAW)
LOW - R7 color noise only removal (without touching luminance noise!) (see here why R7)
HIGH - current GRDII NR OFF
I'm sure, the hardcore GRD users would love the complete OFF option. Someone may say "hey buddy..why don't you use RAW then?". The problem is, that in RAW, one cannot use the Continuous mode, bracketing and maybe one or two other features. This is why the NR OFF switch (with RAW like noise) would be more than welcome in JPEG.
2) HIGH PRIORITY EV Bracketing at least in range +-1 and 2EV. Current +-0.5 is practically useless for HDR photography. I think this is a second most important addition (apart the total NR OFF switch). Ricoh is loosing serious amount of customers because of very small bracketing range. There is a large group of people (including me ) who like to process the HDR images. But the actual AEB +-0.5EV is unfortunately useless for HDR. The only workaround is to change the EV manually and take one shot after another. But this method is usable only with tripod, which is not always anywhere around.
3) CCD pixel mapping in menu. All Olympus cameras have this option and it's really great feature. It not only reduces the manufacturer's costs (because a lot of people hate to see dead pixels on CCD). But it also increases the users' happiness! With this feature in menu they no longer need to pack their cameras every few months, pay for shipping and wait few "endless" days/weeks for its return! I believe this option is a real "customer saver". I know several people who buy Olympus (also) because of this simple option in menu!
4) Possibility to set the ISO in 1/3EV steps. This is one of the greatest things on Olympus E400! It's definitely very useful option to set the ISO in 1/3 steps like ISO 400, 500, 640, 800, 1000, 1250, 1600, instead of just 400, 800, 1600. It seems to me that the current 1EV step settings is just an option to make the things easier/quicker for user (shorter list of values). But I personally think it would be a very useful option to have a full creative control over the amount of "noise". In many cases, ISO400 is too low and ISO800 too high value! it would be great to have an option to set ISO 500 and 640!
5) An option to shot DNG without the corresponding JPEG. I still think this would make the RAW writing even faster and if it would be an optional setting (for advanced users) nobody reasonable will complain about the missing RAW preview. In addition, If the JPEG taken along with RAW is used as a RAW preview, it's not a true RAW preview at all and many users would gladly (optionally) sacrifice it for even faster RAW writing. There is still a small resolution thumbnail stored in DNG. So why not to use it for emergency/composition RAW preview?
6) User selectable (ON/OFF) ND filter. As you may know (or maybe not, because it's a very well hidden feature in PDF manual), GRD/GRD2 have a built-in ND filter. Unfortunately, the GRD ND filter is used only in full auto (camera) mode and only for apertures between F7.1 and F11. But I think it would be very useful (especially during the bright days) to be able to use the built-in ND filter for apertures starting at F2.4 and in all camera modes. I don't know if there is a technological problem to allow this. But because almost nobody here (PRO GRD users) probably uses the auto mode, the user selectable ND filter is a really missed feature in P, A and M modes. And if there is no HW reason, it would be really great to let the user ON or OFF the ND filter. Canon "G" line have this option and the users are very happy with it. It's great if you want to use slow shutter speed during the bright light conditions and without risking overexposure.
7) Interval shooting starting at 1(2) secs and with 1(2) secs interval. Interval shooting with 5 secs delay is too limiting. According my tests, not only the RAW writing speed is improved. The JPEG writing is significantly improved as well and allows to take JPEG files in 2.3FPS, until the card (must be fast one) is filled up. So why not to allow faster interval shooting?
8) Custom setting for level of JPEG compression. Yes, there are Fine and Normal options for JPEG. But many users would prefer to have an option to set the JPEG compression by themselves. And this would make the GRD even more unique camera, because there is definitely not a P&S camera with such option. In fact, only the pro/high priced DSLRs have such option!
11) [b]An option to swap front/rear wheel functionality. (at least in M mode) I think it's much easier/faster to use the wheel than lever? At the moment, the front wheel is dedicated for aperture, which is only about 10-11 possible values? While the lever sets about 40 possible shutter values? In addition, the shutter speed is changed more often than the aperture.
Sure, there is an "AE lock" option, which quickly sets the "proper" exposure values for a given lightning conditions. But as all small sensor cameras, GRD needs to be underexposed a bit to provide optimal output with preserved highlights. So there is still a need to use lever 4-5 times to set the "best" exposure. In my opinion, and from experience with GRD, the wheel would be much faster option for setting shutter speed?
12) User selectable Chroma noise reduction. Some DSLR cameras have the user selectable chroma noise reduction with 3-5 levels of power. It would be great to have this ability (apart the NR OFF) in GRD2 menu. Also, it would be great to use the same chroma noise reduction from R7. It seems to me that the R7 chroma noise reduction in ISO400 shots nicely reduces the color noise and still preserves a very nice amount of details and nice film-like grain. See this post about R7 NR.
13) An option to immediate access the 1:1 preview. Current option to go to 16x preview (by clicking the OK/Menu button in zoomed Preview mode) is not very useful to judge the image sharpness. The preview set to 16x means that the previewed image is upscaled and therefore softened. So the direct access to 1:1 pixel scale (6.7x scale factor?) would be much more useful.
