I have quite a few lenses and while I've come to learn some of their sweet spots I'm interested in skirting the process a little and get to the goodies.
Is it my imagination or did somewhere along the way in researching lenses I thought I chanced upon unbiased and thoroughly technical lens performance charts that depict info/details about how effective/sharp the lens is at various settings?
I'm really interested in finding (and using as much as possible) the sweet spot of each of my lenses. Lately I was pretty disappointed with the 1.4 of my Pentax-A 50mm. Coincidentally, the -A50/1.4 does better at 1.7. I did try it at 5.6 (I'll try and share a sample) and was a bit horrified. So I'd also like to know which settings to avoid. The18mm of my Tamron 18-250mm is also pretty bad. I know you can get some of this info from reviews but I wonder if it's more neatly compiled somewhere to reference?
I almost want to grease pen ideal settings on the lens caps or somewhere though with use I'm certain I wouldn't need to do this.
THanks for listening
