Have been in a power w/c for many years but still go to watch my grandkids playing sports any taking pictures.
I use a DSLR with a zoom lens so the lens can "do the walking"
because I can't. I have found that a monopod is very useful to stabilize the camera and with the adjustable leg it can fit on my cushion or on the w/c footrests or even the floor

If you do your editing by using layers then lightroom is not for you

New point and shoot type cameras with x50 optical zoom are now being introduced and I wonder how such a degree of zoom is achieved on these cameras. To get these equivalent zooms on a DSLR you would need a huge lens of 600-700mm?

Have the same camera and use it to take pics of my grand daughter playing basketball.
I use a similar 60mm f2.8 lens but use shutter priority and a speed of 1/500th sec to arrest motion and increase the ISO to 2000

I just bought a 50mm f1.8 prime lens for my Nikon D5100 for that very purpose.It is autofocus and was $220.
I used it to take some action shots at a basket ball game in the darkest ambient conditions I have ever seen.
Attached are a couple of example taken at f1.8, 1/750s and ISO 6400. The D5100 sensor is reported to have low noise at the higher ISO settings

The advantage to making your adjustments on a separate
adjustment layer is that you are not working on the original but a copy instead. Also, when you use the adjustment layer you can moderate or change the amount of your adjustment by changing the opacity of the adjustment layer

Thanks for all your comments on the Auto ISO mode.
Over the weekend I put it into practice. I went to my gdaughter's basketball game to take some pictures. I had no idea of the conditions but suspected the lighting might be a challenge and I would have no time in the game to experiment.
I ran in the P mode with Auto ISO and set the shutter to 1/800 to freeze the action. The camera set itself to ISO 3200 and,for my first attempt got a few half decent shots. If I had tried to choose the settings I would still be at the game experimenting.
AUTO takes control, but in certain situations, it saves the day.

My new D5100 offers the Auto ISO mode and I'm just wondering if anyone uses this mode and if so, what advantages does it offer?

Thanks for the reply.
I don't understand your comment about adjusting the diopter setting? I thought that was to adjust the sharpness in the viewfinder only. The picture was obtained using autofocus by the camera itself so I don't believe the camera uses the viewfinder.
but I may be wrong.

Thanks to everyone for all your comments and suggestions.
I am amazed at the amount of help that people give on this site.
Have attached the picture of my grandson after sharpening with the high pass filter in PSE9.
I also realized that he was running towards me in the shot and is actually in the air and I only used 1/300 for the shutter speed
which could affect the sharpness.
I thank you all for replying to the "young lady" but, for the record,
I am a 75 year old man -- but thanks for the help anyway!

Pic with high pass sharpening

I have been using a Nikon D40X with the 18-50mm kit lens for a couple of years but about 2 months ago I bought a new D5100 body. Since then I have been struggling to obtain images that look as sharp as I got on the old body and wonder what I am doing wrong? I have included a couple of typical pics from the new camera
