50mm 1.4 on Full Sensor and Crop (Can you post picture examples of both?)

I would be interested to see examples of the same picture taken with the Canon 50mm 1.4 ideally on both a 40D and 5DMKII and preferably wide open or near wide open. Other crop and full frame combinations will do if the two bodies mentioned are not available.

Basically what I am trying to understand what I would gain on my 40D by buying this lens immediately and what I would not get ahead of buying a 5DMKII.

Any other comments in addition to examples would also be appreciated.

Thanks

Plenty of comparisons available, just try Google, you will get more than you can stand. Here is a quick example;

Thanks. That example is not exactly what I was expecting.

What I am trying to understand is if you get better bokeh (or anything else?) on a full frame above a crop camera with this lens, as I presume more of the lens (glass) is contributing to the image? For example I understand that a TS lens will not give the full TS effect on a crop sensor because there "isn't enough image size for it to perform properly", or so I was told. I have taken this logic to thinking about a wide open prime with my above request.

80mm 2.8 on APS-C is like 50mm 1.4 on a full frame in terms of framing and DOF. Your DOF will be about 2 stops thinner with similar framing. Of course a 50mm lens on full frame will be like a 30mm lens on APS-C fro feild of view. So it is hard to directly compare the lens on two bodies.

I think you have answered it for me with the "2 stops thinner". This is what I was trying to get my head around.

I would still like to see what 2 stops looks like, starting at 1.4 - as I currently don't have a lens capable of creating this.

mm yea but the FOV changes as well... so you should compare 50mm(crop) and 80mm(FF) with the same aperture to see the real difference...

I cant locate any comparisons ive done with 50mm at the moment -

Would you want 50mm 1.4 40d
then 50 1.4 5d2 and walk closer to subject to frame them the same??

off hand i have this to compare going from 43mm 40d f2.8 to 70mm 5d f2.8

i know its not what your asking for... but its all I have sitting online atm. I stood in the same spot to take both pics

40d
