The screen is going to be a HUGE drain. It's a much better screen than what is on the 7dc so it wouldn't surprise me if it consumes more battery.

I would turn off the info screen display and disable image review.

That would give you best case scenario to at least see where you might stand relative to the rest of us. Then adjust from there.

7d2

Care to quantify your post? Have you used both cameras to give an opinion? If so, please be a bit more detailed in your response as its far more helpful to the OP if you state the reasons why you say the 7D2.

Still using my 7D2 as my primary but one thing I've recently had to adjust to is the difference in shutter lag. I was shooting the karts in the last 3rd of the long straight so I estimate 80mph for the shifters and when I had time to gimp I noticed a lot of the karts were low in the frame. I eventually got the timing right but I had to vary it based on the speed of the karts on track.

I just looked up what the difference in shutter lag is .10 sec (1d4) vs .25 (7d2). Or about 12 vs 30ft at 80mph between me releasing the shutter and the picture being taken. Remarkably the majority of them the focus is spot on.

Surely the 7d2 cannot have a quarter of a second shutter lag?

FWIW I just got fed up and got a 1d3. [hugs camera]


My imagine composition sucks. I need a heavier lens.

Great post Tony and one of the more relevant but hardly ever mentioned differences that impact the ability to capture 'that' moment, after all a lot more can happen in 1/4 second than 1/10 of a second after pressing the shutter button...if indeed those figures are real.

If they are then maybe that is why I also really still like my 50D, at 0.13 sec shutter delay is almost as minimal as my 1D4 and still about half the 7D2 and both bodies work well for me with fast and erratic moving subjects compared to my 6D which appears to have about the same lag as the 7D2.

With the 6D I often feel I am behind the action, just missing the shot, ie the bat/club/ball/bird/wha​tever is just that bit past the point I wanted. Though this is not an issue with planes or cars/bikes when I can take into account the lag and fire the shutter a tad sooner.


A coupla bodies and a few lenses

You're right. It looks like they are both 55ms when you have AF.

Looks like the .10 and .25 numbers might be for full AF shutter lag. Canon doesn't explicitly list these spec for both cameras on their website.

I first got my numbers here

I don't really understand what this means but these are the specs for the 7D2:

During SW-1 ON, time lag between SW-2 ON and start of exposure:
Approx. 0.055 sec.
*During silent shooting, approx. 0.105 sec.
*With flash, approx. 0.095 sec.
*During silent shooting with flash, approx. 0.145 sec.
Time lag between simultaneous SW-1/SW-2 ON and start of exposure: Approx. 0.17 sec.
*During silent shooting, approx. 0.22 sec.
*With flash, approx. 0.215 sec.
* During silent shooting with flash, approx. 0.265 sec.

Unfortunately they don't list the same for the 1D4.

I will just use both cameras back to back to back in the same conditions and see if there is a real world difference. I just don't have another event till mid July.

Oh Gawd, if any pf those numbers were accurate it would be like shooting an EOS D30!!!

SW1 is the first press of the shutter button, SW2 is the second press. I would expect this to really only apply in One shot AF, as in AI Servo the system now has many different options, rather than just simply always releasing the shot. If you already have focus locked then you should normally see a shutter lag of 0.055 s, unless you are using flash/silent modes. The longer times, approching 0.25 s in the worse case also include the time it might take to focus. Of course that will probably have its own set of (unpublished?) test parameters.

Thanks for the explanation, Alan.

I didn't think I was seeing anything approaching 1/4 of a second.

One thing that I did not see mentioned in this thread is the AF cross type availability. The problem with the 1D4, is that there are NO f/5.6 cross type AF points; all f/5.6 AF points are linear.
This means that if you have or plan to use an f/5.6 lens, like say a 100-400L I/II, 70-300L, 400 5.6, any of the 150-600 lens, or any faster 2.8 lens with a 2.0x TC, you have access to NO (0) cross type AF points.

These same lens on the 7D II, would have access to 65 cross type AF points. This is why people have claimed that the 100-400L, seems to perform better on the 7D II than with the 1D4.

.

It is actually a good point!!!

Besides, I noticed that the price of new 7d mark ii on ebay has down to 1199. For a used 1D4, it still cost 1500-2000.
I think for performance/value, the 7d mark ii is a better choice.

After reading this thread, I will go for 7d mark ii!

But I am still surprise that the price of 7d mark ii drops so quickly.
