Description

Testing Canon 55-250 mm lens for astrophoto, so far I am dissatisfied: this lense shows all possible optical distortions: significant vignetting, unflat field, coma, astigmatism etc. For regular photography this lense is fine, but not for astrophotography. With LF-lens the picture is REALLY different. Clear for me that the decent fast APO is the best solution.
