I was planning on buying either a 5.6 400L or 100-400L but since taking pics at a sporting event which went on till dusk I am leaning more towards a 70-200L 2.8 usm IS and a x2 tele converter. I need to email my wish list to my partner tonight as he can go to the shop in the USA tomorrow. (Almost half the price of the UK!)

Best roller bag?

Please please your thoughts more than welcome:lol: :lol: :lol:

Doesn't the TC reduce the aperture limitation? Could be wrong, but using the TC on an F2.8 lens will not provide F2.8...can someone else verify this please?....I would hate to steer the OP wrong......

70-200/2.8 + 2xTC = 140-400/5.6 and is a little soft at 400mm.

Ranking in terms of image quality from all that I read (because I am asking the same question as you):

1) 400/5.6
2) 100-400
3) 70-200/2.8+2xTC

BTW I'm going the 2xTC because it's the cheaper route. FWIW a 1.4xTC works much much better and great image quality.

yes...2.8 would lose 2 stops. I use a 1.4 TC on my f/4 and max aperture is f/5.6 while mounted. Camera sees it is recorded as 5.6 on EXIF also.

If you plan on using TC all the time, get the right FL lens without TC. Also, 2x TC will degrade your image noticeably but with 1.4x, your image loss is minimal.

Depends on the sporting event.

The 100-400 and the 400/5.6 are certainly not the most effective sporting lenses. Additionally, sporting lenses don't really need IS.

An f/2.8 telephoto is certainly what is best for a sport's event, but a 200mm lens is a bit short except for small courts/tracks. 200mm would be fine for tennis - for example, especially if you are close to the court. But football or track and field certainly call for 400 or even 500.

If you need the reach and plan to use the TC a lot, then I would be more inclined to use a prime. Althought the 70-200/2.8 is not a bad lens to use with a 2xTC, I would rather use the 300/4 with an 1.4xTC. IQ should be a mark better with the prime but you loose the zoom. It's up to you, your style, and what you are going to shoot to decide if zoom is really important.

Perhaps he already knows the 2-stop requirement, and is desiring the flexibility of using it WITHOUT the TC in low-light events that fit that focal range.

I love my 70-200 IS 2.8 with Canon's x2 TC II.

But, most of my photos are shot at the 70-200 range (the money shots, if you will), and the TC provides mostly a great reaching capability, at the cost of 2 f stops and a bit of sharpness. It is softer than the regular L quality, but not soft enough to make it a bad choice. Plus for News and Press, I am better off sporting the TC in a pocket, than carrying a whole other lens altogether.

70-200 + TC = f5.6

So if you are bird watching, and you already know 400mm is what you want, I would go with the 5.6 400mm L. It will retain the most quality out of the image. And none of the kinks you have to put up with the 100-400L.

If you are not sure, the 70-200 IS with the TC may be a better solution, as it gives you a much wider range of use (70mm-400mm) with either L Quality, or still very good quality.

Just my .02 cents, and I'd love to hear which one you choose in the end, and specially how it works out for you.

Cheers,

The EF 2x II doubles the focal length of any lens it's mounted to, and reduces its effective aperture by two stops. With the EF 2x II, AF is possible with any EOS body if the lens has an f/2.8 or faster maximum aperture, and compatible Image Stabilization lenses maintain the IS feature when used with any current EOS camera. (external link)

The above statement is linked to Canon website. I think the 70-200 with 2x would be faster than the 100-400 @400 but maybe not as fast as 100-400 at 70mm.

The 100-400 would be less expensive but I think the 70-200 is the nicer/better option. Also weighs half as much.

Also the 100-400 will loose AF when used with the 2XTC. The AF on the 70-200 with the 2XTC works fine.

The 100-400L (much as I dislike it) has superior optics to the 70-200mm f/2.8 IS USM plus 2x TC combination. They are also both f/5.6 at 400mm. Also, according to Canon, fitting a 2x TC decreases lens AF drive speed by approx. 75%. Not a great feature for sports work.

If you plan on using the 200-400 regularly, then I would suggest getting something "native" to that range.

The 70-200 f2.8 IS + 2x TC combo isn't that terrible. But you have to remeber that the 2 stop light loss is constant (as opposed to the f4.5-f5.6 on the 100-400) you lose significant AF speed (though the 100-400 ain't no thoroughbred...) and certainly lose at least some IQ.

The 400 5.6 from what I hear has very fast AF. So that might be good for your style...though f5.6 might be a tad slow???

If you only go 200-400 occasionally, then the TC's are certainly worth a look.

Wasn't aware of that! I did know that less light from the TC makes the AF hunt more but that 1D bodies were immune to that problem up until f/8. Does it also apply to 1D bodies?

Sigma EX is not a bad idea.

As far as AF, and seeing that the OP said shooting an Evening Sport Event, I would try to leave aside any TC. My 1D II Works just fast enough for a soccer game during the day, while using the x2TC and at 400mm. It does hunt. Evening? Sheez, unless it was baseball and I wanted some more static shots, it could get very tricky.
