old camera and problem
May 2, 2016 16:09:52 #
This photo is typical with this camera. It is a Nikon P 100. I must be doing something wrong. Please help! Each time I use the zoom on this camera I get photos like this.

1/60 of the second exposure time with a 400mm+ focal length is the issue. A good rule of thumb is 1/focal length is the longest exposure time. It's only a rule of thumb, but useful.

The 1/focal_length approximation is correct for a 35mm size frame, but the Nikon P100 has a 5.7x crop factor that has to be accounted for, so at a focal length of 430mm the rough guide for a shutter speed that can be hand held is 1 / 430 * 5.7, or roughly 1/2450 of a second. That is for an average person and with VR off.
With VR enabled, if it is given half a second or so to stabilize that might mean something between 1/300 and 1/600 will work, but that isn't a good bet either, and note that at higher shutter speeds VR is not effective. Shooting at 1/1000 with VR on is probably not valid.
The point that 1/60 of a second is too slow is absolutely correct!
The solution for that kind of zoom range is obviously either a monopod as a halfway measure that will often work or using a decent tripod to assure good results.

Thanks to all who posted responses to "old camera's" problem. I leave mine on automatic so often anymore that this may or may not be an issue. Anyway, thanks. I have another question to ask and I have watched to see if someone else would ask it. Haven't seen that yet. My question is my eyes. I do wear glasses. All of my cameras have a visual correction on them. Should I be shooting with or without my glasses. The prescription is very mild for my distance needs. For reading, most prescribers like to push me up every time I come in. For reading I was told I need to use 3.50 and up. I buy them across the counter and for my needs, I use 1.75. If I had to use 3.5, I would have to hold the book about 10" from my face and no farther. When I tell them this, they seem almost angry with me for disagreeing with them. Last time I had my eyes checked, the 3.50 ended up in my desk drawer where it can't hurt me. Right now I am using an older 1.5 reader.
SO what should I do, glasses or not?

I don't have a strong distance correction so I wear my glasses when focusing. As far as reading glasses go - the bottom line is what strength are you comfortable using? And since we usually use computer screens much further away from our eyes, using 1/2 the strength of reading glasses for computer work is usually comfortable.

My last few working years were as an HVAC Technician and it was difficult to learn from someone else using my doctor
advise because tech manuals are generally in much smaller print than other texts. When I tried to explain that to the doctor, he would explain that he used the numbers he found on the machine that checked my eyes. I knew that and that was in itself, the problem.

First of all, that is an instrument, not a machine. Second, he sounds more like an optician rather than an ophthalmologist. Having gone to both, my choice is the latter.

Ditto regarding shutter speed. I shoot with glasses on. not a problem. But shoot which ever get s the best results, for you. Do you use live view? BTW nobody can hand hold long focal length in live view without camera shake.

Another possible might be that the subject may be too close. An alternative to the tripod (the better solution) would be to increase the ISO.

I have a Nikon with a digital zoom and a Canon with an optical zoom. IF there is a suggested difference in the procedure, I'd like to know what it is.
Thanks,

Optical is better...digital is a interpolation of optical.
