I am not sure but if you have a new system and its one of the new high seer 14 or above it may have a variable speed motor on it to save you $$$$ ! have a new 16 seer its 100 plus degrees outside yep its going to be a running a lot..fan that is ..
question new and I was wanting to buy this lens but $$$ man is there one you may recommend that is same speed and durable as this..???
I am just learning this digital camera stuff, had canon AE-1 for 20+ years, Loved it.. took thousand family & friends
