This is an entirely new page. I will be adding to it from time to time comparing power output of flashes and will also show the unique light patterns of each flash. I really enjoyed making this page and am excited to add more soon.
It is a very long process to clean the Aperture Oil in a Pentax Takumar 28mm 3.5 SMC but it is well worth it as this is a great little lens and are easy to find. Just make sure you have a spanner before you start repairing the lens.
