Quote:Yes, vingnetting is a problem at 70mm f2.8 and 24mm f2.8. Close focus performance is strange at f2.8 on 36Mpix sensor it could be better. You can look full resolution photos here: https://www.flickr.com/photos/[email protected]/
Not being able to read your language, but I notice a few downsides right away...
- Very high vignetting (light loss) wide open at 70mm, for 70mm. Through the whole range actually, but more used on seeing that for wide angle.
- iIndeed, does not look very good at close focus. Not really acceptable?
- That tendency to produce swirly bokeh due to mechanical vignetting, pretty unusual for a modern f2.8 standard zoom?
