In looking today at a question in the lens forum, it prompted me to look at the lens review.
We are woefully short on specifications for the lenses.
How can we build up these?
for example on the takumar 300mm F/4.0 all we have is the weight of the lens for each series.
What about minimum focusing distance, filter/accessory diameter, number of elements & groups, maximum and minimum length, tripod mount included Y/N coatings etc.....
I know we are developing some data like this for non Pentax lenses, it would be great if this could be there for all the pentax ones as well
