The f/2.8 is a beast in size and weight compared to the f/4. I can hand-hold the f/4 all day, no problem. I couldn't fathom doing that with the f/2.8. If you use a tripod, the f/4 does not come with a collar but it really needs one to balance the camera if taking active photos. For example, I took a bunch of shots of big cats at the zoo with the f/4 without a collar and I found myself constantly using my left hand to balance the lens. I was exhausted afterward.
The f/4 is super sharp. I have yet to put the f/2.8 through its paces, so I cannot comment on its use in the field.
I dont find the f/2.8 very heavy and am quite comfortable with it on a 1D4 all day.
Suggest you use the rifle holding position with your left elbow resting against your chest. This is a very stable technique and takes little energy.
I would suggest using 2 flash, get the iso down to a max of 400, and on a crop use the 24-105 for the majority of photos. Indoors if space is tight then flash + a wide zoom will be perfect.
can someone please explain (in detail) the weight factor of the f/2.8?
it looks like I am going to probably purchase the f/2.8 based on all of your help (thanks) however I am nervous about carrying this very heavy lens around.
ok next question
how are you doing so many exposures with the 5DII which only has 3AEB
I am hoping this new upcoming magic lantern adds it back in an works better
the last one i tried was unstable at best
I shoot in manual mode - f/11, ISO 400, Mirror lockup and Promote Control trigger. The Promote allows you to program in what exposure range you want, depending on whether you want to start with a highlight, shadow or mid-exposure value; program and hit Start. They're a bit pricey, but after I used one, I have to say it was worth it for as many houses as I shoot.
I understand that but I addressed that issue in my post. Users of the 7D that want to update (ones with lots of EF-S) can look at the new xxD. The APS-C market is a little too crowded. I think moving the 7D up and allowing the 70D to return the xxD line to it's historic position could work. Make it a $1400 camera with some of the speed and possibly the AF system of the 7D and a new sensor. As it stands Canon has 4 cameras with the same sensor between $800 and $1400this would work but they would have to give the 70D equivalent weather sealing to the current 7D to keep wildlife and birders happy. I definately agree with you as the 60D currently seems like the odd one out, doesnt offer alot more than a 600D and is no where near as good as a 7D with all 3 having the same sensor.
No one here has suggested that you lose your 1.6 crop. If you want that there will be plenty of new 1.6 crop cameras (xxD)
All of this is useless anyway because Canon isn't going to do it. The 7D will be APS-C and it will have tons of MPs.
I'm going to tackle this subject from a different perspective:
Would the 5D2 remain on the market as a "current" model even after the release of the 5D3?
I think the situation has been a lot more clear with the recent price drop of the 5D2 under 2K. It seems like a lot of people are reacting favorably towards a full-frame body in the lower price range.
At this point, I think it would make a lot of sense to keep 5D2 on the market under 2K while introducing the 5D3 at the usual 5D-model price range.
Just some thoughts...
the 24-105 is good dont get me wrong but the IQ of the 16-35 flat out destroys it however there is a massive zoom range difference and the matter of the 24-105 having IS and being a full stop slower you did specify f2.8 at the slowestYour specs have really boxed you into a 16-35 f/2.8L in the Canon product line. As you probably know, that’s a $1,400 lens. With the 5D II running at around $2,000, might this be the time to jump to FF? 17mm on your 40D is equivalent to 27 on FF, so your 24-105 would actually be wider than what you’ve been shooting with.
The 16-35 definitely looks like a sweet lens. However, the fact that it's a big chunk of the cost of the 5d2 which pulls the 24-105 into about the same range is a very good (and dangerous to my pocketbook) observation. I will have to ponder! +1 for the suggestion--thanks!
since you said that i heard they are going to put the 5DII AF into itWe know Canon is watching very carefully how the pro-market reacts to the death of the APS-H sensor. (Repeat after me: Canon will not put an APS-H sensor in a 7D. Canon will not put an APS-H sensor in a 7D...)
But, they could decide to sufficiently upgrade the 7D to target pro-sports and wildlife shooters. Either in a base model or in a 7D-X.
Don't know about whether they're going to stick the APS-H sensor in or not, but one thing Canon can do is to upgrade/update the original 18MP sensor (seems like there's been complaints about it...).
Of course, we can always hope for a better AF system
