A very interesting read from Roger Cicala about optical quality - toni-a - 11-14-2020 I often talked about bad lenses and sample variation and need t frequently adjust lenses, since a friend of mine :Tanios is in the business of lenses maintenance (he used to work for Canon Lebanon but now he has his own business and Canon themselves are outsourcing repairs to his atelier) Tanios has explained thoroughly these issues to me and I tried to share what I learnt here, however Roger Cicala does it way better than me so I shared this good read https://www.dpreview.com/opinion/6856813208/roger-cicala-the-difference-between-sample-variation-and-bad-copies-part-1 https://www.dpreview.com/opinion/6856813208/roger-cicala-the-difference-between-sample-variation-and-bad-copies-part-1 |
