Every now and then I'll take my M2 or M3 out of the cupboard to run through the shutter speeds a couple of times and after a minute I'll think "dang this thing is nice ... why don't I use it more?"
Then I'll take the Ikon from the cupboard and look through the finder, take note of the extra shutter speed, marvel at the accuracy of the metering and the option of using AE, remember that I can load a film into it in less than twenty seconds!
Then I'll put the M2 back in the cupboard and continue to use the Ikon! 😀
