This might seem like a very obvious question, but the moment you try to define a set of criteria to quantify ‘good’, you soon realize there’s quite a lot more to lens performance than immediately meets the eye. So, for those of you without the ability to try a large number of lenses – let alone samples of the same lens – how do you know if the one you’ve got is ‘good’?

Following an odd resurgence of emails lately about system matching, lens quality (on non-native systems), sample variation, decentering and similar topics – I thought it made sense to revisit this topic from the archives. ‘Which is the best lens for X?’ might seem like a very obvious question, but the moment you try to define a set of criteria to quantify ‘good’, you soon realize there’s quite a lot more to lens performance than immediately meets the eye. And this is before (but really should be much after) creative considerations, perspective etc. In any case: for those of you without the ability to try a large number of lenses – let alone samples of the same lens – how do you know if the one you’ve got is ‘good’?
