Canon battery grip and increased fps?

  1. When I was using a Nikon D300s and the Nikon MB-D10 battery grip I could increase the frame rate from 6 to 8 fps using 8AA batteries. Can I do the same with a Canon battery grip? I use a 6D and 70D.
  2. I do not own either the 6D or 70D, but my understanding is that the Canon battery grips, although they contain 2 batteries, deplete only one at a time. I assume this approach gives you no benefit when you need more power in the moment. I believe it only helps with increasing the length of time you can shoot. I wish it were different, or that a switch were offered so you could select either benefit as you need it.
  3. I dont believe that is correct. From my experience using the 5D MK IV with grip. Both batteries are being drained equally at the same time. I see this when charging both batteries, they are drained equally and take about the same recharge time, even when topping them off from partially drained states.

    Essentially they are two batteries in parallel so you have doubled the amp hour capacity of the camera. I had grips on my older Canon APS-C cameras also. When using those cameras with an older 2000 era Canon 100-400mm lens, I noticed the lens just responded faster in AF using the grip. Even the IS seemed to be more stable.. The lens motors are being powered from the camera. Some lenses may have more of a power draw. Depending on the model camera and battery, entry level EOS, prosumer, or professional, the power available for the lens and camera body could vary on battery model and age of battery and current draw and remaining voltage in the battery. There is a window where the camera will function and it has a little play but performance may vary.

    It is possible how fast the lens can focus will depend on current draw and available power, so this could have some bearing on FPS. I recall a discussion about noise also and that photos taken with a partially drained older battery may be a little noisier than those taken with a new fully charged battery. I have searched for this discussion and have not found it yet. I believe that discussion was discussing third party batteries and new and used Canon batteries and noise in photos being worse with weak batteries. The discussion could also have been around a comment that someones camera seemed to be taking noisier photos than when it was new, and that may have been how the whole battery discussion came about. Old batteries with less charge capacity and less power for the camera sensor and processor.

  4. I think the best you can hope for is have a new fully charged battery, the fastest write speed memory card and expect the frames per second Canon wrote in the specs. Of course a grip will never hurt and may help insure good performance.

  5. Thanks for the clarifications, Mark. I never owned a grip, but only recalled another user state what I had posted above when I was considering getting a grip for my Canon 7Dii. I had hoped it would help with faster AF, especially on my longer lenses, but was told it wouldn't, so I never pursued the grip. It's nice to hear of your first-hand experience being otherwise.

  6. One benefit of no direct FPS boost and extra features offered by Canon grips is that you can get knock offs for nice prices. - I have some Meike for 5D IV and am content. - Build quality and feel of the buttons aren't up to Canon standard, but it is at least usable and improves ergonomics with a heavier lens a bit. I thought I might need it later, when I'll turn WIFI on.
  7. Personally I mainly found the grip to offer the advantage of easier portrait mode shooting.

    On the other hand, I found the camera-plus- grip to be a little bulky on the XXD models, whereas it made a "Rebel" camera more comfortable.

    Obviously, this is a very personal decision.

    I found the knock-off quality to be more fragile than the originals, although many flaws were shared.
