I have a canon 70/200 IS USM F2.8L, shall I buy a TC1.4 or a 300L IS USM, whats best, I know the TC is cheaper, but mayb the 300mm lens would be slightly better, any views please guys. Thanks Nick

Since it is only 300 you are after, and you have 70-200 2.8, TC would be my suggestion.

The 300mm must be the better lens - itís not a zoom.
The 300mm come in f4 & F2.8, which one were you thinking?

The TC will add more glass and reduce max aperture.
A 1.4 TC will reduce a stop of light taking the 70/200 f2.8 to f4, but 1.4 x 200 only = 280mm, could use a 2xTC but then lose 2 stops of light.
Also AF will not work with some combinations of TC and Lenses, but I think your probably OK with yours.

If you can afford it get the 300mm, shaper shots and more reach.

Having looked at your portfolio another consideration is AF speed....
Once you attach a tc you will slow your lense's AF speed down to a snails pace.
If the 300mm your talking of is the f4 version then forget a tc as you will again lose to much AF speed and if its the F2.8 you will be able to a 1.4x pretty comfortably.

Can't say I've noticed that on my 70-200 f2,8

I use a 1.4 TC with my 70-200 f2.8 and I find it works very well indeed. There is no easily noticed impairment to either AF speed or image quality - at least at the sizes I print to (A4).

Whilst I am fairly sure a quality prime 300mm (f4 or f2.8) will have the edge over the 70-200 + 1.4 TC, the question is are you prepared to shell out at least £1,000 for that edge.

If you want longer reach, then maybe the 100-400mm is worth considering. Yes it will be a further stop slower than the 70-200 + 1.4 TC, but you will gain an extra 120mm or reach. You could then add a 1.4 TC to that and have 560mm of reach (albeit at a maximum aperture of f8).

Whenever I consider these things I baffle myself with the options, and end up wondering why I didn't pick a more straightforward and less costly hobby.

Has anyone tried a 700-200 f2.8 with a 1.4 tc attached aimed at a high speed moving subject?
In my guided opinion the Af will slow and the sharpness of the lense will drop off.

Yes, my pf banner shot of a stooping falcon, was taken using a 70-200F4L (IS turned off), with a 1.4tc attached.
I dont remember the exact camera settings but as you can see, I nailed it.
Or did you mean something faster than a stooping falcon?

Ok Ok....A teleconvertor attached to a 70-200 be it an f4 or f2.8 will retain the same af speed as the lens without it.
If not a tc will most certainly improve the lenses af speed.

How foolish of me to think different!!

Have a look at Neil (Javam) PF.
He has some stunning airshow shots with 70-200 F2.8 + 2x TC (yes, 2x!).

I Have used my 70-200 f2.8 with a 1.4 Extender many times and have hardly noticed any drop in AF performance.

I was also going to mention that Cole - I think this(70-200F2.8) and the 300mm F2.8 are two lenses that get very good results from the 2x tc.
