Computar 105-150 MM Lens.

Under the el cheapo thread the Computar 105-150 mm being sold by the surplus shed was highlighted. I purchased an example. Yes it was cheap but a meopta plastic fantastic enlarger lens can be found cheaper and would likely perform better. the computar was made for a medium format twin lens reflex camera. I managed to adapt it to my bellows using an M 39 adapter. I had to drill some holes in the adapter. The lens being a zoom is a real pain mounted vertically it slowly creeps out of focus and if left unattended in five minutes it will have "fallen" from 105mm to its full extension of 150mm. I took one serious photo at 150mm here it is. Its Ok for a less than half sized photo. However that picture is as sharp as I could get it and "blunt spoon" is the analogy that comes to mind. The lens is a pain to use and IMO a McDonalds meal( note I don't eat McDonalds) would be a much better purchase. I soon cheered up when I discovered I had won a Rodagon APO 90mm F4 enlarger lens on ebay for just under €150.00 ( it just has some Schniederitus)
