It's clear that designing a user-friendly user interface is one of the really big challenges in technology. It's rarely done really well, and often disastrously bad.
I really like the Olympus Pen, but Olympus's menus... oh my gawd. (Maybe not "disastrous", but bad enough.)
I had only use the Pen Lite with auto ISO which I really like. But a couple days ago I wanted to change it to a specific ISO Setting. And despite my 13 years of experience with a similar number of camera, for the life of me I couldn't figure out how to do it!
I mean, setting the sensitivity, how much more basic does it get? Many cameras have a dedicated button for it.
It got worse, I had to hunt in the manual to find out how to do it. But I finally found it:
First I had to press the OK button to activate the "Live Control" screen. Hardly intuitive, the OK button is used to confirm settings, not starting them.
And then ISO didn't, contrary to my expectations, appear immediate and clearly on the Live Control screen. I had to scroll down beyond the first "page" to find it. Closer to the top was things like "focal length" (which I am not even sure what's used for, since most lenses tell this to the camera, it may be for the rarer instances that this does not happen) and Image Aspect Ratio, which I believe most users rarely change.
You would think that after well over a decade, camera settings had not only become pretty intuitive, but also found a set of standards, that they would be similar on most cameras. But far from it, they are all different, and most are pretty confusing.
Another example: the Olympus cameras have a "Super Control Panel", which handily displays basically all the important settings of the camera on one screen. But guess what, this is by default turned off! And to turn it on, you have to go deep in the menus and know exactly what you're looking for, you will never stumble over it on your own. (It's even called SCP in the menus, who would guess that that stands for.) I only heard about it due to an article which reader Bert helpfully referred me to.
Sometimes you almost miss the good old Pentax K1000, durable (though actually not that heavy), cheap, and ultra simple, it had the aperture and the shutter speed to set, and that was about it. It didn't even have a friggin self timer! The camera was made and sold for over twenty years I believe, particularly schools loved it, it was cheap, durable, and it taught the basics without fancy distractions.
It also didn't have an on-off switch! You had to put on a lens cover to save battery. But it was fully operable without battery (of course without light metering though), a rarity. It sold over 3 million units between 1976 and 1997.
I never used it myself, I used a Konica TC and later a Pentax ME Super. I never used a manual camera, though it probably would have been good for me. Fortunately I liked to read about cameras (I tore through the dozen books about it the library had), so I picked up what aperture and shutter speed do.
