Hi, this may sound like an absurd question, but please stay with me. Please teach me.
Assuming I use nifty fifty wide open and use a 2x converter with a crop sensor.
- Would it become 100mm f2.8 (effective 160mm f2.8 on apsc). Basically where will be the final fstop. I'm not sure how it works when teleconverter is attached?
- Would there be a visible difference in sharpness?
- Will there be any issue in focusing, with this arrangement?
Please direct me if there is already a thread discussing this.
