I have done tests with and with-out the Nikon TC x1.4 and can see no loss of image quality. The turning of a 400mm lens to a 560mm is a major advantage when photographing birds. The size, baulk and weight of the lens is also not changed too much.

With modern DSLRs with dramaticly improved ISO at higher settings the need to have an f4 large 500mm lens is no longer needed, when as a 77 yr old, I try to reduce what I carry when out on a walk in a bird reserve.

My big 500mm f4 comes out when I spend the day in a fixed location like a hide or can work from my car.There is no doubt that the image quality at wider f nos is better with the big lens. Stop down the 400-80mm a bit more and it also is pin sharp.

Than goodness long gone are the days of a Hasselblad and a 500mm f8 lens and 50 ISO transp film. Working like this in Africa in the 1970s bird photography was not easy. Here photographing white rhinos in Rhodesia with a Linhof 6x7 1970!!

I am in admiration of your courage and envious of your flexibility to squat that low, let alone take photos in that position, Graham. :lol:

Time will only tell whether the convenient portability of the 300 with a 1.4 will be sufficient reach. But I am trying to stop carting large lenses around on the off chance something might pop out of a bush.

If my commitment to bird photography gathers momentum and I find myself more frequently sat in hides, then I may well invest in a longer heavier prime. But at the moment it's a peripheral interest for me that doesn't warrant high investment.

Not that brave I had been photographig them for a week with a game ranger keeping an eye on me. They are not as dangerous as Black Rhinos and they were more than happy with us being down wind.

Far more interesting is my progress with the D850 in very dull rain this morning very poor light, 80-400 at 400mm plus x1.4 this is about 1/2 the full frame. 1/650 sec f8 ISO 2600. (Is this all you need!!?)

Many bird photographers still believe that the bird only needs to be 1/3 of the frame to ensure a good part of the habitat is part of the photograph. The fact you are able to attain such clarity from that crop suggests that, YES, it may well be enough.

So FX400 x 1.4 = 560mm, cropped 1/2 full size ....so 1020mm equiv.

DX270 x 1.4 = 567mm

So the question is....... if you had put the 80-400 with the 1.4x tc on the D500, set it to 270mm and done the same 1/2 crop, would the image have been as good?

It was 35 feet from our back bedroom window and sorry ISO should read 2500. This would give a top quality A3+ print not bad with such high ISO and dull light. Exposure was spot on with matrix metering and focus on AF-C single point on head.

Get the 200-500 and be done with it.

It's a possibility Jonathan, if I find the 300+1.4tc falls short of my needs.

I find that the flexibility of the zoom really wins.

200-500 is cheaper as well at £1150 versus £1170 for the older 300mm f4 or £1500 for the new version.
Dont forget that the D5, D850 and D500 have a minimum max aperture of f8 NOT f5.6 as was the case in the past.

Some lovely images there Graham. I particularly like the cormorant...wonderful lighting, colour, composition and detail. May I ask what camera/ lens were used and how much cropping? :bowing:
