hi everyone, I am a regular visitor of this site and want to ask a question..I searched this site and others to find an answer to my question, which is the heading by the way..can the nikon 300mm pf be used with the tc 17eii for wildlife and bird photography?? I own a nikon D500 and the very good 200-500mm but find it a bit bulky to carry around when on a long journey or using a public transport..so I was looking for a lighter and probably cheaper solution..now, many of the users here will tell me to get the 500mm pf which I want to get but cannot afford at present..I am an amateur wildlife enthusiast who is looking for good photo opportunities, not expecting NatGeo quality of shots but printable will do..so, I ask you guys to post pics if you have any with this combo..also the pros and cons too..I am specifically interested to see action shots, like birds in flight or low light photos where these are pushed to the limits..I request you all to share your knowledge, experience and thoughts in this regard..any information and pictures will help me make my decision..please contribute..thank you.
First and foremost, you might find the 300PF a bit disappointing compared to your 200-500, especially if you're shooting distant or small subjects and cropping heavily.
Now that's out of the way, there's no doubt that the 300PF is very good, one of Nikon's best and most unique lenses. If you want a small light telephoto lens this is one of the very best options available.
I would be somewhat hesitant to use it with even a 1.4x TC, let alone a 1.7x. The D500 (I'm assuming that's what you're using) is already a pretty sharp/highly resolving sensor and putting a TC on any lens is always a trade-off. Yes you will get more magnification (as in, the image gets larger), but this does not always mean more detail or better images. Whenever I used the TC14-III I always felt it reduced sharpness and contrast and increased CA, which makes your images look worse, especially when you're cropping in. The 300PF is sharpest stopped down to f/5.6, so with a 1.4x TC that means you will have to be at f/8 for best results. Your AF speed will also be reduced. With the 1.7x it's even worse as your wide open/focusing aperture will be above f/5.6. Only the center AF point or a few points around the center will work - a bit of a shame when you're sporting a D500 with 153 AF point covering the full width of the sensor.
I guess what I'm trying to say is, don't assume that a TC is a silver bullet which turns your 300mm lens into a 450 or 510mm lens. But, at the end of the day it will get you somewhat close to what the 200-500 can do in a much smaller package. I would just try to appreciate the merits of the "bare lens" 300PF than try to replicate the 200-500 @ 500mm, because imo that will just lead to disappointment.
The strength of the 300PF is when you can get close (and it helps you get close by being so small and easy to handle).
Source - I used to shoot the 200-500 regularly, my partner shoots the 300PF. I've used her lens many times, and while it's excellent for what it is, I always went back to the 200-500. We also tried the TC14EIII and both agreed that it wasn't worth the hassle on either lens.
