Advice please..I have the 70-200mm F2.8 and am very happy except on occasion would like a little extra distance..ie Imperial Hill,KLAX. Thinking about the canon 100-400mm but lots of money so any advice on any alternatives ie 1.4 or 2.0 extenders which I'm told will give comparible results ?? Other alternatives Sigma etc but what would give the best results in sharpness and quality ??
Thanks in advance

Hey,

I have the 2.8 IS 70-200 and the 1.4x and it is good, but when i borrowed my buddies 100-400 to go to LAS there was no comparison. If you want to shoot at a distance go with the 100-400. There is too much glass with a converter, I hear stay away from the 2x. Hope that helps,

Grant

I own the 70-200 F4 L (love it to bits!) but have toyed with the idea of extra range for over 12 months now and finally decided to avoid extenders. Apparently the 1.4x is very good but it will be detrimental to quality in the long run. I too have heard the 2x is a nightmare!

I've looked so many times at the 100-400L but it's a heck of a lot of money. I'm now looking at the Sigma 120-400 Apo OS which is a lot cheaper (although still not exactly cheap!) but have never used Sigma before and don't know how comparable to the Canon Ls they are. Anyone know how good (or bad) this lens is?

Thanks,

Karl

Hi,
I have the 70-200 F/4, the 1.4 Ext and the 100-400, and I can tell you that unfortunately there is no way around the 100-400 at this stage within the Canon range. The 1.4 Ext is OK but degrades the quality, particularly around the edges, and "only" gives you 280 mm on that lens, and without IS.
So, while the 100-400 is far not perfect (the 70-200 is still the sharpest Canon lens around), there is really no better zoom alternative.
I haven't tried myself the Sigma, but have spoken to people that have and they all say that you can see (and feel) the difference in price.
In the end it's a matter of budget, but if you can wait and save, I would go for the 100-400.



Just sit back, relax and have a glass of Merlot...enjoy your life!

one point that has come up using the 100-400 is dust being drawn in due to the push/pull action. Is this a valid point or just a one off ?
If I were to crop a shot using my 70-200 f2.8 how would it compare to a shot taken with the 100-400mm ? Still undecided wether to buy the bigger lens but have decided not to go down the route of the extenders. Any more comments much appreciated.
Thanks to all so far

OK, Andres has heard that the Sigma 120-400 is of lesser quality than Canon's 100-400L, that's good enough for me. But what about the 'Bigma' (I believe it's the 50-500?) that lots of people here swear by? I see lots of nice images here taken with it so maybe it's much better than the 120-400?

Karl, have a read of this review

http://www.the-digital-picture.com/R...f-4-6.3-EX-DG-HSM-Lens-Review.aspx

Looked at this myself but not convinced the cost saving at the expense of image quality is a worthwhile trade-off. Never used it so could be completely wrong.

Having looked at several reviews the best of the Sigmas seems to be the 120-400 F4.5-5.6 DG OS HSM. Apparently the 'Bigmas' (50-500 and 150-500) are very soft above 300mm, especially wide open. They also seem to handle colour and contrast not so well.

According to many of the reviews the 120-400 is pretty sharp above about F5.6 and remains so throughout much of the focal length, except perhaps pushing toward the 400mm limit. It also appears to handle colour and contrast better than its bigger siblings, although it still isn't up to Canon L series in terms of contrast quality.

The general consensus is that, while not quite up to the standard of the 100-400L, the difference in price makes it equally attractive.
