It seems there have been a lot of threads lately trying to show the 5D3 has the same resolving power as the D800.

You have access to the RAWs. Prove whatever it is that you want to prove but don't assign false meaning to my post.

Not sure why....the D800 holds a 28% linear resolution advantage that is easily seen when good optics are used.

Has anyone seen the possibility of a focus error in the optics used for my comparison?

Maybe, have you tried bracketing focus?

No, I haven't adopted this procedure as of yet.

It equates to one extra print size....say 20x30 over 16x24 for the 5D3.

I don't know about the numbers you state above but I would agree wholeheartedly with the spirit of your assertion for the full-size images or even images reduced. All I am saying is that there could be a diminishing return at play here.

When I made my purchase decision to go with the Nikon over the Canon, I just cropped a 12x18 out of a 20x30 print and made my decision.

As I said in my OP, the D800E images are fine if not viewed too closely.

It was obvious in print the D800 had more resolving power. We wont even mention the difference in DR.

My comparison was not about the 5D3 per se. It was strictly about resolution.

In my exp when downsizing a higher resolution file one may need some extra sharpening, since putting pixels together may reduce detail, this has been known:

Actually, I was going to post this very link for the benefit of others in this thread who do not seem to understand the degradation involved with downsizing. I have adopted a multi-stage sharpening process that dates back to the first time I down-sized a jpeg. I also do not use bi-cubic sharper. For the images posted that I put through my own workflow, they went through several stages of resizing and sharpening. My sharpening decisions are based on the setup of my particular monitor, the primary presentation medium and may seem over-sharpened or under-sharpened for your monitor. For all other images posted, the initial instructions were for each reader to apply his/her own PPing.

Sorry for the delay in responding.
