I am aware that handling f4 and 2x might be beyond the 7D's capacity.
I now use the Canon 2x III on a Canon 70-200 f2.8 IS II, and I am very pleased with the match.

Focusing at f8 (f4+2x) is unreliable on the 7D this is a 7D issue and has nothing to do with the kenko converter, except that the kenko allows the camera to try and focus.  Put a Canon 2x converter in the same position and the 7D won't even try to focus.  The 7D is limited to focusing reliably at f5.6, which is why the f2.8 + 2x works fine.

These were recommended by a photographer in Canadian Outdoor Photography.  I got a pair and found that they work well.  I use a pair of mitts over them when it is realy cold.

[ It's very common to take a spill on a bike, and just one would wreck that lens.

its not that common to take a spill.  I've actually seen a birder around my area with a case built onto his bike frame for carrying either a telescope or a big lens.

I subscribed to Photo Plus when I first started in photography and it was nice, since I needed something basic but technical. aGree with others, after exactly one year, noticed the material was basically recycled, so stopped then. The video tutorials were nice, though, as I started working with Elements. Now I pickup a few here and there from the bookstore when something catches my eye. Usually at the airport, when waiting for a flight.
+1 on the recommendation for a class. The best money I invested was a Saturday class at the local community college. Enough to get started well and a chance to ask questions from a professional.

Enjoy the new found hobby!

 I picked up a couple of copies of Photo Plus  at the newsstand then subscribed for a year.   Definitely learned quite a bit from them,  but I didn't renew the subscription as I found that I outgrew them.

Of course. You paid for it you have the right to demand what you expect from it. It is just some people expect unreal things. Of course a lens is a +/- 10 has a serious problem. I tested 5 with focal and no one was more than +/- 1 so I stopped because got bored of testing them.

Really?  Every one of my lenses is out by at least 4.

My 50mm f/1.4 is out by +7, my 70-200mm f/4 is out by +5 wide, and -1 tele.  My 40STM is a +4.

My 70-200mm f/4 is tack sharp, and even before the +5 fix, it took fabulous photos.  Some of which grace my office walls at 20x30".  There's no reason I'd send it back for being out by 5.

Similarly, the 50 f/1.4 is a great lens, it just needed a little adjustment.

Maybe its your camera that's out by 4 and all your lenses are pretty much okay .

Need to wait and see if the 35mm beats the sigma.
As for the 14-24, too late I already sprung for the Tokina 16-28.

Note that it comes in  a discrete green colour.  Not the crowd attracting white of Canon L lenses.

There's also the extra weight to factor in, there's a reason the 150-500mm is called the Bigma :P. [/quote]

Actually the Bigma is the 50-500mm.   The 150-500mm is the Bigmos.  The Bigma is supposed to have better IQ than the Bigmos.

So the question is, should I get:
  • The 1.4x III extender for my 100-400L
  • The Sigma 150-500 mm lens. I intend to keep the 100-400L.

What experience do you have on the Canon 100-400L + 1.4x
The sigma 150-500 mm Lens

Thanks in advance.



I got a sigma 150-500mm as my first long telephoto lens.  I still have it and use it for airshows where the zoom is a big advantage, but the IQ doesn't compare to my Canon 400mm f5.6L.  I can crop to better image quality with the 400mm and  the IQ using a Kenko 300 1.4x on the 400mm is still better than the Sigma

I think you would be better getting the 1.4x converter, than the Sigma 150-500mm.

EOS Bodies / Re: Cards for a 5D III?
« on: October 30, 2012, 02:28:31 PM »
I've just upgraded from a 7D to a 5D III.  Will I get any noticable difference if I upgrade my 60mb/s compact flash cards to 90mb/s cards?

Here is a site that compares the various cards.
You will see a difference if you shoot long bursts, but it isn't going to give you 50% more.

I agree with a previous poster that having one really fast card is a good way to go if you know that you will be using it.
Note that there is no point in getting fast SD cards for the camera, the camera write speed is limited.

You don't say which lens came with the camera.  If it is the 18-55mm then you have a good lens to to practice with out doors.

I would recommend adding either the 50mm f1.8 or the 40mm f2.8 lens for your indoor shooting. 
As others have suggested a dedicated flash would also be useful, personally I would recommend the Nissin Di 866 as a better value option to the canon 430.

Thanks  for the replies.

EOS Bodies - For Stills / 5D3 focus for birds in flight

I expect that using single point expansion is the the way to go  but what AF Case is best for birds in flight ?
And are there any adjustments to the default case setinngs that help?
