Full Frame vs Crop Part Deux...
Hi all,.

Thank you all for the great information when I asked about the differences between full frame cameras and crop cameras....

My question comes because in reading reviews regarding high end Canon lenses, it seems that about 1/2 the people doing the reviews say that the lenses work better when using a full frame camera over a crop body..

Please tell me why this is and if it would behoove me to sell my brand new 40d and buy a 5D. If possible, a simple explanation would be great..

I am truly looking to do high end, high quality photography and money is secondary..

Of course, I know experience, knowledge, etc is the most important thing, but I wouldnt mind starting out with the best gear possible from the get go. In using the "L" series lenses, would a full frame body like the 5D be better? Or, is it not worth it?.

As always, thank you all in advance,.

Steve..

Crop-sensor cameras only use the middle part of the image, which typically suffers from less of the aberrations and distortions that affect sharpness, and image quality generally. So it seems counter-intuitive, doesn't it, that lenses could actually perform better on full frame cameras? But they can - reasons include:.

- To make the same size print from the crop camera, the image must be enlarged more (1.6x more, obviously). But that's "warts'n'all" - the image is magnified, and the aberrations are magnified too..

- With the full frame sensor, you can use about 1 2/3 stops smaller aperture and still get similar depth of field, background blur and (even having increased the ISO speed to compensate) low noise. And what do you get if you stop down a lens from wide open by one or two stops? Often as not, a *big* improvement in sharpness...

Teh best gear is, fiorst of all, a highly debatable concept, and second, a genuine waste of money for most people, you included, almost always..

Go take pictures with your new camera and quite worrying about buying more stuff..

Plus, have you changed the air in your tires for the winter? That's more important than buying a 5D when you have a 40D already..

Well, if that is truely the case, then you should go medium format....

I'm calling my mortgage broker as I type this. I think taking a second out on the house would be a great way to finance these cameras..

Thank you for the links!.

I think the first thing I will spend my money on is a better spell checker for you BAK..

Secondly, you have no idea who I am and I would appreciate you not making assumptions on my behalf..

Thank you,.

Steve.

PS: As for changing the air in my tires for winter, where I live winter doesnt really exist...So, again, please dont make assumptions about me...

Half my lenses are for 35mm cameras and the rest are for a digital SLR with a 1.5 crop factor. In practice, I see no significant difference in the results. Frequently, I see information about why, theoritically, this or that is better but in practical use the differences are not significant.Patrick T. KellyOaxaca, Mexico..

I have the 5D and recently purchased a 40D. The first one I received was badly front focusing. The replacement one was much better but not perfect. I have sent it and a few lenses to Canon for calibration and I will reserve final judgement until after I get them back..

My initial impression of the 40D was that it is certainly capable of highly detailed images (when focused correctly) and very fast shot to shot speed. The noise has been a disappointment. The 40D at 200 ISO looks worse than the 5D at 400. I find that I have to shoot in Raw mode to get the most out of it. The extra magnification shows up lens errors that were not obvious with the 5D..

You have not mentioned what types of photography you plan to do. If you are shooting high speed action sports where you need long lenses and faster shot to shot speed, then the 40D may be a good choice or if money is no object, then consider the IDmk3..

If you are shooting portaits or lanscapes where speed and long reach are not important, then definitely get the 5D (or wait for it's successor.) The 5D has a special quality to the images that is hard to describe. The larger sensor size gives a 3d quality that is not there with the 40D...

If it's image quality, the 5D beats any canon crop camera hands down. Less noise, more pixels, better JPEGs out of the camera, more dynamic range, less DOF (if wanted). All my lenses look better on my 5D than my old crop camera, except my cheapest ones like the 50 f1.8 (sold), and 28-105 f3.5-4.5.

Bottom line, the 5D will give you better quality images that print larger and have more "pop" (whatever that is...).
