Not only that, but we're dealing with what has happened to the lenses during their now long lives. Was the one I tested serviced? Was the technician who serviced it competent? Has it taken a fall that loosened something? And on and on...
Unless you're LensRentals, it's always going to be like this. Only rarely have I had multiple copies I could compare, and even then anyone reading my thoughts needs to take them with a grain of salt!
I use the personal experiences of people who have a track record of knowledge and experience, and who are using similar equipment, to get me in the zone. Then I roll the dice if the balance of experiences has been positive.

Originally posted by bull drinkwater what we are dealing with here, is the personal experiences of our forum members. our ratings are based on our equipment and skill level. a valid review would rrquire testing at least 5 of each model in a professional laboratory.
my results have been good with both the a and fa editions.
