I recently obtained a new 5D2 for my work as an event (conventions and trade shows mostly) photographer. The 5D that I was using for the past six years is 12.8 mp while the 5D2 bumps that up to 21 mp making the file sizes (I only shoot jpeg) nearly twice as large.
Am I correct in thinking that this will only slow down transfer times to my lap top without providing a noticeable benefit to the picture quality, especially because my images for this type of work are typically only viewed on computer screens, or occasionally printed in a newsletter at a very small size. Very rarely will an image make it to a printed enlargement as an 8x10, or possibly (but even more rare) an 11x14.
I have tested by shooting the same image twice, once at large fine and once at medium fine.
I did this about twenty times with different subject matter from low key to high key and in between.
When reviewing the images on my computer, zoomed in, zoomed out, looking for sharpness, color and noise characteristics I was unable to see any difference at all between large fine and medium fine.
The prime reason for wanting the smaller file sizes is that I am very often told "we need those shots for our website or blog immediately" When this happens I still have a full shooting schedule to cover (which somehow the client forgets) with assignments in different locations around the convention center and off site so any time saved in transferring images to my laptop, then to a flash drive and then to the client, sometimes to the client's computer is very much desired.
So what I am asking for are opinions from those who may sometimes lower the picture quality as described above, and those who are far more technically advanced than myself to give insight as to which way to go here.
Thanks for any opinions I receive on this.
