What is upper limit for mp and handholding?
May 8, 2018 12:06:31 #
I was reading a thread recently where it was suggested a 50 mp camera requires a tripod for best results. That got me thinking. My camera does about 18 mp and I exclusively hand hold a 100-400 telephoto lens on my crop camera. I am fine with the results. I realize everyone is different in steadiness when it comes to hand holding, but let's assume I'm average. Would I start to get more blur at 25 mp? 30 mp? 40 mp? For those people with higher mp cameras and telephoto lenses, what do you find as your upper limits for CONSISTENTLY getting good hand held shots? I do mostly ships & stationary birds. Does it vary by camera maker depending on how good their image stabilization is?

Higher density sensor record more information. Motion is part of it. I had some issues with the D800e. Now with the D850 I have more issues.
Stability is a must for these high density sensor cameras. They can be handheld. The shutter speed as with long lenses must be adjusted for that. My 'stability' allows for reasonable results at 1/200s when using the D850. Lower than that it becomes a mess. Best speed for me is really 1/500 with this camera. Since I use ISO 200 for best DR results that can create issues with the dof setting and overall exposure. The saving part? The camera invariant sensor and it incredible DR.

I don't think you need to think of a 50mp camera much different than you would an 18mp camera in terms of motion blur. A body with a large sensor like Canons 5DSR or Nikons D850 will show flaws more readily but I'm sure it's manageable with some changes in your technique. You just need to be more conscious of your technique of holding the camera steady, panning smoothly, and pressing the shutter with a smooth action rather than a jerky stabbing motion. Perhaps you can replace some of the older lenses for newer lenses with better stabilization.

It depends on what am I shooting, if its stationary subjects, I usually opt for a tripod, especially if shot with a long focal length, if I'm shooting any action, sports, BIF, and or macro, I choose to shoot handheld! I would not feel any different about that, if my camera were in the 80-100mp ballpark!

Odd, I never considered shooting differently when using 400 ASA or 25 ASA film. I just shot. Even when pushing Tri-X to 1600. So I wouldn't consider doing anything different between 8Mp and 25Mp sensors.

I think that your question and the beliefs that go with questions like yours are misleading at best and bordering on scare tactics at worst!
I don’t mean your question specifically but those types of questions and they push a fear for high mp cameras.
MOST of the somewhat reliable information I’ve seen does not have anything to do with a person’s physical abilities to do photography but with the vibrations that one can not physically avoid the are part of the relationship between the mirror and the sensor that we commonly refer to as mirror slap, for which companies build systems into the bodies of those cameras to mitigate the effects.
But to answer your question more directly, 1, I don’t know the answers to the question and 2, I handhold the 100-400 on my 53mp Canon all the time with no I’ll effect from blur, or at least not that I can detect at 100% crop.

You "may" get better results with a tripod - it depends on what you are shooting and the magnification. A 14mm lens will not shake nearly as much as a 600mm at 14 ft. But a 105mm macro at 12 inches - 1:1 magnification, will require a fairly stiff and massive tripod.
Some camera manufacturers include image stabilization in the body. It is more common to see it in a lens. The newer gear has better stabilization.
That being said - I shot this at about 20 ft distance with a 600mm lens and a 36mp camera - hand held at 1/25 sec. And this was repeatable.

Wow! That answers my question up to 40mp any way! Great crop closeup.

Thanks!
The Sigma is heavy at 6.5 lbs, and when you add the camera, it is over 8.5 lbs. If you are strong enough, the extra inertial mass will help resist micro-movements from the camera itself - shutter, mirror, and even the stabilization system itself - can cause vibrations. All to often you will see people facing the subjects with their bodies, which will tend to encourage lifting the elbows causing some instability. It is important to use a good position - shoulder pointed at subject, elbows tucked against rib cage, lens cradled in left hand, back of camera pressed lightly against forehead - and the most important thing, breathe normally. When I am setting up for a slow shutter speed shot with a long lens, I try to slow my breathing and press the shutter at the end of an exhale. It works for snipers, and it works for photographers.
One last thing. Lay off the coffee, tea, energy drinks etc -

The crop shot is truly amazing! Glad to know that Trouble's relatives are as pretty as she. Really a wonderful shot.

The most critical variable in this is the amount of light you have to work with. Lots of light equals faster shutter speeds. The next variable is the lens focal length and quality of the VR. The third thing is how stable are you as a shooter. ( And remember a monopod is more stable than hand holding.) So for a given situation things change in terms of how much stability is required for sharp images.

Gene51 – That is an incredible shot!
If you had told me you were going to shoot this at 20 ft distance with a 600mm lens and a 36mp camera - hand held at 1/25 sec. , I would have said IMPOSSIBLE; can’t be done.
But it looks like you did it! Very well done !
From now on you will be known to me as, Gene51 - The rock .

I try not to have limits - because they are so limiting !
Motion blur is exacerbated by higher pixel density and magnification - but is also dependent on your perception and threshold for blur. So, yes, "best" motion blur results for a stationary subject will be with a tripod !- this is a fact.
For nature and wildlife, the only time I hand hold is for birds in flight - for everything else I am on support of some kind - even with smaller/shorter lenses. And, with longer ( higher magnification ) lenses stabilization is NOT just about motion blur - it is also about AF and compositional accuracy ! Some of my bodies and some lenses have IS - but I never trust them.

Gorgeous crop, Gene. For all cat lovers, and there are many, this would be a wonderful wall-hanger.
