What reviewers say

Both reviews praise its compact transport size, accurate autofocus and sharp results, while criticising extender incompatibility. Cameralabs finds strong distant corners throughout the range; Dustin Abbott sees a weaker patch at 135 mm. Their EOS R5 stabilisation tests also differ, with Cameralabs achieving around four stops and Abbott around six. Cameralabs favours keeping an existing EF equivalent for value.
