70 300 VR + Kenko PRO 1.4



First day testing my 70-300mm VR + Kenko PRO 300 DG 1.4x Tele Converter. I have read several reviews with this combo working well together. Most stated you would need good light to get good IQ. It didn't take long for me to figure that out! It was a partly cloudy day and hazy (smoky) from the fires in Florida, although adequate lighting, so I thought. Locking focus on a BIF was quit a challenge to say the least. Taking 10 to 15 seconds to lock focus in some cases and complete failure in most. Static subjects were not much faster although it did lock focus. I tried manual with better success. Hopefully there will be more sun and less smoke tomorrow.



Thanks for looking
Jeff

I don't think it has much if any affect on IQ.



Remember this is 1 of 50 shots taken and 20 shots missed because I could not lock focus.

When doing the math 1 good image out of 50 is unacceptable, not to mention the missed opportunities. I will crop instead.



Thanks for looking

i once rented a canon 300mm f4 IS and used a 1.4x tc with it. for bif, i too noticed that the focus lock was much slower. bummer

Very nice shot.

My experience with teleconverters (Nikon's) is that you'll need a fast lens (f2.8 or better) or else you'll miss alot of shots.
