Optical Test Chart

For checking the camera and lens performance...( also enlargers) I found it whilst going through some old photographic equipment I haven't touched for ages This is a single one of ten cards to be set up on a wall and photographed under even lighting. I used it on a test of a Nikkor prime 35mm 1.8 lens taken on the floor with a Nikon 7000 camera with an external flash unit in the camera shoe, the flash head swivelled towards the ceiling to bounce even light all over it. Just thought it may appeal to the more techie minded Blippers perhaps, more of a relic from the dim distant past, today:)
You can see it's dated 1978 in print but Patersons are still in business today, where Johnsons of Hendon, another old established company, are now dissolved.
Needless to say I'm delighted with the performance of this particular lens:)
