I am using this 2X extender with my 135L, and I must say that after a little micro adjustment of +5, this is incredible! I now have a 270mm f/4 lens, and the images are very, very nice. Wide open (f/4), there is a little softness or dreamy effect, but stopped down to f/5.6, images are extremely sharp and contrasty. Yes, this will enhance any flaw in your lens, but with higher quality lenses, should not be much of an issue. AF is fast, I have not had any problems with its speed or accuracy. Overall, I am extremely pleased with this extender.
Very much impressed with the performance of the lense. Everything about the care and shipment of this product was superb. Thank you Overstock for my pleasant first time purchase experience with you.
I got this lense the same time I got my camera. And I have to say, I'm pretty impressed. I wouldn't recommend this to a professional. But for a beginner or a intermediate photographer it's a perfect fit. It's a great lens and I would recommend this to anyone who would like a medium duty lens.
I use this lens on my Sony A7R II and it's incredible, not a very detailed review I just wanted to take care of this notification - Trust me though, can't go wrong with this lens if you're looking for something in this focal range and it's tested as one of the sharpest lenses known to man.
