As a recent owner of a Panasonic GX8, I have noticed how companies like Panasonic offer a curious mixture of extreme levels of customization, while at the same time, really limit the potential of a camera's hardware controls. Buttons On the GX8 for example, there are several function buttons that can each be mapped to literally dozens of different functions. But at the same time, when in aperture or shutter priority mode, in their default mode both of the control dials control the same parameter (aperture or shutter speed) with no option to remap one of the wheels to control another parameter. This got me thinking that when it comes to customization, there is so much further that we could go with these cameras. What's more frustrating is that most of these improvements are software related and would not be hard for the engineer to program. For example: -on a typical camera, any function button can only be assigned a single function. However, I have never owned a camera that lets you assign a 2nd function to the button by performing a "long press" of the control (like you do on smartphones) or a third control by doing a rapid "double tap" For example, on my GX8 I have one of the function buttons assigned to ISO, pressing the button turns up the ISO to the next level, which is handy. But it only goes in 1 direction, if I want to take the ISO back down, I am back to using the traditional cursor dial or wheels. This would be a perfect place to implement a long press function, where a long press of the same button takes the ISO down a level. Now the one function button works with ISO in both directions. Another example could be the auto exposure lock button, you could have a long press turn on something similar like focus lock. Ideally the cameras menu would let the user completely map any assignable functions to every button's normal press, long press, and double tap states. Focus Ring: On any auto focus lens for M43, the focus ring is actually just a rotary encoder like any other dial on the camera, and it is spoken for when using it in manual focus mode. I am not sure how typical I am, but I don't actually use manual focus that often, so for all the time I am using auto focus, that big comfortable dial is just sitting there completely unused. It would be a cool option is when you are in auto focus mode, the focus ring could be re-mapped to other parameters like aperture, iso, exposure compensation, white balance mode, etc. Of course when you switch to manual focus, the focus ring would have to go back to controlling focus, but for me at least, that's just not that often. Since the focus ring does not have any detents or clicks, the menu could also have a control for how much rotation equals a virtual click. Users could set it to whatever feels right to them. Display Screens The last disappointment is the lack of customization on the display screens. For example, on my GX8, I like to keep the viewfinder display on the "simple" display setting where it only shows aperture, shutter speed, exposure compensation, and ISO level. However, I wish it would also show the current battery level as a final 5th piece of information. It doesn't, and to have battery level shown, I have to toggle to the full info display, where the battery is now shown, but the top of the viewfinder is also filled with many, many other settings that I never change and don't need to clutter up the viewfinder with. It would be really great if the user could really set up the display screens the way they wanted them. Allow them to pick which pieces of info in the simple and complex displays, and even choose which "slot" they go in on the info strips at the top and bottom. Some may say this would be hard to set up in a camera menu, but I think it could be done. The GX8 uses a graphical approach to let you assign the tons of function buttons, you see a picture of the camera and its buttons, and you scroll to each one then select its function. The same could be done with a graphical representation of the simple and complex display screens. I know the camera companies are probably afraid of making things too complex, but the thing I wish they'd remember is that none of this stuff is a default behavior, it only is available if someone goes into the menu and wants to change it. They could even hide it all in a special "expert" menu that you have to purposefully go into, and leave it all out of the normal menus. I think Olympus took this approach for some deeper settings with the older Pens although if memory served, it was not implemented very clearly and when I owned an EP-2 I initially was saying "where the heck are the rest of the settings?" Overall, I really do wonder: -who the product managers are for these devices -how much they use these products in a real world basis and consider common user "use cases" -why they do not have the product managers and engineers monitor forums like these, see what people's chief software-based complaints are for a mode of camera, and then quickly address it with a firmware update. Olympus seems to have had a change of heart about this and is now doing firmware updates with new features more lately, but I don't think Panasonic really is? Thanks!
