Hello.
I am in need of advice returning to photography realising that much of what I once knew has escaped my head.
Thought it was logical to eliminate sources of error by calibrating lenses...
So, calibrating infinity focus.
Contacted Sigma for advice about range to take test images. They advised there is no specific distance but advised using a subject over 200mm that has something in front and behind.
Briefly reassuring until hyperfocal near limit emerged from my distant memory.
How can focus be tested at a range under the hyperfocal near limit?
Am I being thick?
Regards
Steve
