Nice examples of aperture and DoF but was it intended for this thread?![]()
If you're mind is set on the 40D I'd look for a body only and get better glass. (perhaps the Canon Zoom Wide Angle-Telephoto EF 24-105mm f/4L IS USM would be a great place to start)
There's negligible IQ difference between the 400D and the 40D.
You just don't get better value for money Canon lenses.
And please don't recommend an f2.8 over an f4 just because it's faster. The price difference is not justified.
The differences between the two do however justify the price tag IMHO.
Live view, more fps, and a semi sealed body...
Are these shots digital or film? Don't forget that DoF is influenced by the image sensor size. 35mm film size (full frame) will have far shallower DoF than an APS-C size at the same focal length.300mm at f/5.6 looks like this:
The cat's nose is not even in focus. Only the eyes.
The light was dim. That's why I used f/5.6
200mm at f/2.8
Click for 100% crop.
Only the right eye is in focus.
But with a wider shot you can get it all in focus at f/2.8
200mm at f/2.8
So you don't have much depth of field at big f-stops on telephotos.
At 300mm, I've found that I mostly use between f/8 to f/16.
I was just using the grey model for illustrative purposes. BTW - Would a US grey lens or non-grey lens make any difference at all here in SA?
I have the f2.8 ISWhich 70-200 do you have? the Canon f4/l? I'm thinking a 2x extender might be in order for my next purchase.
I know the 2x means a big reduction in aperture and no auto focus on my 70-200 but I only want it for whale watching from the house and some lunar photography so I can probably live with it.I have the f2.8 IS
I have a 2X TC , and would not recommend going more than a 1.4X TC.
EF 70-200 f2.8 L IS USM
How is this lens?
A grip is always an option for the larger handed among us

EF-S 17-55 f2.8 IS USM
I like the look of the EOS 30D, EF-S 17-55 f2.8 IS USM but for one thing EF-S and I really want a full frame next.The 17-55 is the one that lives on my 30D - this lens is superb for natural light indoors etc. The wide aperture and electronic tripod is great.
If only I'd had the money - even for the non-IS version . . blaady kids and their always wanting clothes . . . and food!The 70-200 F2.8 IS is legendary.
Its the battery life that counts tooIt's not the size that counts, but the slowwwww hand.
How's that song go ........
I'm still half asleep - I meant to ask how this one is:
I gave it a long hard look when I was shopping for my first one but ended up taking the 24-105L since the price difference is rather small.

The side controls are awesome . . . when I remember to use them

Like I mentioned earlier - going from the 400D to the 40D makes no sense for me <had to stress thatI've decided to stick with the crops for now - I may be tempted to pass the 30D onto the wife, and go for the 40D - I doubt if I'll she'll buy into that seeing as she really likes the 350D with the 28 1.8 attached.
You've got to wait for the kids to get out the house and buying their own luxuries like food and clothes.
Yeah, but we were talking about Canon lenses. Are the Pentax lenses good value for money? I like their cameras. They have built in IS in the body. That's kinda cool. Maybe my next digital will be a Pentax. Maybe the K200D, yes? Then I can use my Pentax lenses with it.Ever looked at Pentax?![]()
Those are Canon 5DAre these shots digital or film? Don't forget that DoF is influenced by the image sensor size. 35mm film size (full frame) will have far shallower DoF than an APS-C size at the same focal length.
How is this lens?

You prefer doing it on the camera?These are my custom vivid parameter camera settings.
