Got my new AF-S Nikkor 300mm f4D IF ED yesterday, and was a little surprised when I looked in the rear of the lens and saw the shutter blades.
Yep, no rear element. To my way of thinking, a permanently attached T/C is almost a necessity.
I rather impetuously jumped in last week and bought a Tamron 1.4X SP AF Tele-Converter.
I took about a dozen test shots today, with and without the T/C. It was quite gusty, and somewhere along the line I realised that the tripod collar wasn't tight. My fault.
Anyway I'll post one of each test and would appreciate any comments re the relative sharpness of the two combinations.
To me, the bare 300 looks marginally sharper, but not by the proverbial country mile.

However, and isn't there always a 'however', the T/C wasn't really snug on the lens. Was a bit of play. Not good.
Both shots had the same minimal processing. I'd appreciate any feedback, but I'm leaning towards the TC-20E III. I just want to get it right this time.
