About 25yrs ago - a Novoflex trigger-operated follow-focus shoulder stock with I think it was 400 & 600mm lens heads.
Think I used it for one photo.
I'm another member of the ranks who've got an unused monopod sat in the corner. I'm sure I'll use it one day, maybe.
I've also got yellow and orange Bay-1 filters for my Yashmat 124 but I've only ever shot colour film or slides through it so they've never been used.
Nikon F100, bought thinking that it's one of the ultimate film cameras, used once because the amount of automation moves my involvement in the process a step or two back and it feels like I'm shooting digital without the option to chimp. Same goes for the lenses I have for it.
Zorki-4, classic rangefinder looks, has sat on a shelf for the last couple of years because it's too bulky to slip into a bag like the Electro 35 GX, which also doesn't get enough use.
I'd better stop, I could go on like this for a while...
So your elbow problem attacked your brain too?!Sold a mint Nikon D300s because of an elbow problem and got an Nex 7
I thought a Gorrilapod would be a great idea, got one and quickly realised it wasn't up to the job of holding anything bigger than a compact.
A pointy bit for the end of my monopod to stick in the ground.... bought last yr.. still in packet.
Screw in grad filter now that was a waste of money and time
Yes, I had one of those as well.....had a lovely pink cast too.........
But the real humdinger was a Canon portable storage/viewing thingie. used it once in anger. Cost £300
canon 7d
too much like hard work use my 650d instead
