Outstanding images with this in conjunction with my 300mmF2.8L. Frustrating that it does not work with the 100-400 F4.5L ll USM, while it did work with the original version of this lens, (although this was not consistent). I also own the 1.4x extender. Curious that it works with all of the above mentioned lenses.
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 like how quickly you can change lenses with their magnetized rims and with a minor alteration to my pelican case i no longer have too remove my cell phone protector case in order to use these camera lenses!
