Well... know the feeling of pedal to the metal, know you're topped out, but squeeze the wheel, curse and will more out of it, but know it's not there? Well, the 100-400 II gives you what you were missing plus some breathing space. Same for the 5DIV and I think the 24-105 II will follow in the same vein.

I have another question, and I suspect only Talley can answer it.

Do you think I need to upgrade my memory card? It's a tough decision .

I don't see the problem; by my calculation that should be good for a solid 0.128s of 4K video :mrgreen:

5D4+1.4tc+400mm=30mpx@​540mm

7d@+400mm=20mpx@640mm

so, 5D4 w/tc is 84% of the reach of the 7D2 (both with the same lens).

so, lets 'crop in' to gain reach (that's how a crop sensor works, right?)...

so, what's 84% of 30mpx? ... 25.2mp

I haven't done any math since high-school, so I'm curious if I got any of that right.

:-)

While it's not as simple as 2 x focal length = twice the linear crop (as the field of view gets a little funky for wider focal lengths) for longer focal lengths we can just about wing it. So... 640/560=1.14x (linear difference). Note that is unsurprisingly also the ratio between 1.6 and 1.4 (because we started with 400mm on both bodies, and effectively increased it by those two multipliers).

If we crop a 5D4 shot by 1.14x then that's 30 / 1.14^2 ~= 23MP.

Assuming the TC didn't have too much of a negative effect then you'll have an image that's slightly larger in resolution than the 7D2, but the same framing.

The TC + crop on the 5D4 may result in the same overall noise as the 7D2 (assuming similar noise per unit area); but I'm getting above my pay grade now.


Camera, some lenses, too little time, too little talent

It's interesting hearing the views about the 5D IV vs 7D II. I was planning to keep my 7D II for when I need extra reach and 10fps (airshows mainly) and I thought they would make a great complimentary pair of bodies. Having used the 5DIV a few times now I'm finding it harder to conceive of a situation where I'd put down the 5DIV and not feel a bit deprived!

I find magnetic fields and forces of gravity a nag to resist, so I just let it happen. Comes out better and naturally that way. :-)

I have always advocated for using which ever AF point gets you the shot. It's far better than focus recompose in many cases.

This compatibility with the MkIII 1.4x is the first solid reason I have seen since they arrived fro me to upgrade to a MkIII 1.4x

There, I talked about the 5D4 again! :)


Case in point (not the most exciting image ever but you'll get the point). Far better than focus recompose for a static scene, and if the subject is moving it is a whole new ball game:)

5D4 -4 EV live view owns all. This thing focuses on what I cannot see period using this method!!! Eat that 1dx.

I guess it depends what you shoot, the 1DX for my style of shooting will always be king over the 5DIV, I do actually want one to compliment my 1DXII for next year. Its a phenomenal camera no doubt, but its certainly not the best. ;-)a

I'm finally starting to have a look through the manual (I wish they'd included a full one in the box!)...there's a lot of technological advances over the 5D2 and 7D!! It's a whole new load of things to have to think about! I like the sound of the anti flicker function, that's clever.

All the digital lens optimizer settings sound interesting but are they necessary? What affect positive or negative do having them set have? I'm talking Digital lens Optimizer/Diffraction Correction/Distortion correction etc.

Because of fps and extra weather seal and battery life?

Better have a good read in the handbook. Some of those items are mutually excluding with others, have effects that aren't applicable for all types of shooting, or sap battery resources as does DLO.

So the in-camera DLO... is it applied to RAW images? So when I import them into LR, are the DLO effects present in the files?

(I asked this earlier, I don't think anyone saw it)

Looking at the manual, yes it is:

Sounds good to me, thanks Mike. It's just super confusing because everything else in that menu are not applied to the RAW files.

DLO makes a significant difference, so this is great that you can apply it to RAWs pre-LR. I'll test for myself to see how different the files look in LR with/without DLO applied.
