5D MarkII vs 40D

same FOV you get the same DOF

Not sure that is correct.

Given the same field of view on both cameras, to achieve the same depth of field, you will need to stop down by a factor of 1.6 on the full frame camera.

For example, if on 40D you're shooting with an aperture of f/10 then GIVEN THE SAME FIELD OF VIEW, you'll have to shoot at f/16 on the 5D2

by more, you mean less.

in general, for a given framing you will need to stop down about 1-2 stops more to maintain similar depth of field

by more i mean. you have a wider depth of things in focus. isn't that what depth of field is? narrower means your plane of focus being smaller????

Don't worry about it. I went from a 30D to a 5D Mark II and I love it. You will, too. (To me, the most outstanding feature is the low noise. It never ceases to amaze me. You will have no regrets, I promise.) Don't obsess about DOF. It will be fine.

I am sure you are right just a concern as I do some group portrait work and would not want have the people out of focus.

In this type of situation to you leave all the AF focus points on (5D MarkII). Otherwise with DOF and single point anything out of that plane could be out of focus.

Turning on all the points isn't going to increase your DOF. Only stopping down will. The only thing turning all your points will assure is that nothing that you wanted in focus, will be

You shouldnt have any out of focus shots with group portraits regardless of what sensor you use ...(40d vs r5DMII). The bottom line is here that as long as the groups physical depth doesnt exceed the DOF that your apertures are set to then you will be ok. Thats standard in any camera system...medium format sensors included...Your group portraits would have to be very deep if they exceeded a f16 /f22 aperture on a sdMKII anyway .

What peoples keeper rates between the 40D and the 5DII AF performance wise for sports, under the Center point AF, AI Servo mode?

I have shot with my 40D since it came out. Bought and received my 5D Mark II in April. My 40D is now a backup body that I have to force myself to use (just to make sure it's working). After you see the quality of photos that you get - DOF, colour, tonal retention, shadow detail, low light, sharpness, full frame, you name it, I bet you never go back. Here's one of my favourite DOF photos with my 5D Mark II and I could never get this with my 40D. This is as shot, just cropped down and watermarked. Shot with Canon Macro 100 f/2.8, ISO 100, 1/160 s, Av mode.

I just sold my 40D and regret it. I sold it on Friday and was at a street event on Saturday and would have killed to have a second body to avoid switching lenses, which I had to do often and missed a zillion shots.

After the 135L comes I'm looking for a used 1D MKII (for it's AF and FPS).

The fact I sold my 5D classic to fund my 5DII saddens me deeply. I miss my reliable 5D and would have loved having 2 FF bodies for events. My 40D does not do the job nearly as easily. The PP for the 5D's are so minimal and the images are usually very nice.

No comparison between the 40D and 5D2.

However the 40D has two major advantages:
- AF points are faster, and much more sensitive in low light
- Faster fps

And of course:
- Price
- Mass

5D2 is better in all other respects (barely in some)

I currently have a 40d and may purchase a 5D II from a friend. How does the focus compare between the two? Can I still take good fast action pictures with a 5D II?

It is a thread which has been dead for three years.... Rise from your grave!

Try out your friends camera and see for yourself. A large part of things will be your own shooting style and abilities. Some people say yes, some say no. With you having access to both cameras you need to figure it out based on you and your needs.

Most people will tell you the 5d2 does not focus well in low light, and that the focus system was the weak point of the camera.

I figure I would search before starting a new thread

Right now I just take pictures of my 3 year old and 2 month old. So most of my shots are portrait or candid. However, soon I will be taking pictures of my son in sports and I don't want to end up shooting myself in the foot if the 5d II is not up to the task.

The center focus on the 5DII is outstanding. The outer focus points on the 40D are better than the 5DII.

Either are excellent as long as you're not in extremely low light conditions.

What are you shooting?
