Is 16x optical zoom much better than 10x?

by minniepauz / March 17, 2012 4:43 AM PDT

I currently have a Cyber Shot with a 10x optical zoom and although I LOVE this camera, I need more zoom. I wish I could afford the Cyber-shot Digital Camera HX100V which has 30x zoom but the price ($400) is a bit too much, plus the camera is larger than I want for my purposes (nature walks, birdwatching and family photos).

I'm looking at the Cyber-shot Digital Camera HX9V which has 16x optical for $300, but I'm wondering how much difference I'll get compared to my current 10x. There should be some place online that shows pictures with various zooms, but I can't seem to find them.

The HX9V is the same size as the one I have now and is perfect for slipping into my pocket or carry in my hand, but I don't want to spend $300 if the 16x isn't going to give me much more than what I have.....and THEN for $100 more I could have the 30x.

What to do what to do!! Happy Any advice would be appreciated!

Focal Length

10x and 16x doesn't mean much without knowing the focal lengths of the lens. For example, a 10x lens that starts at 38mm equivalent, will be 380mm at the telephoto end. But a 16x lens that starts at 24mm equivalent will be 384mm at the telephoto end...barely a difference.

You can use this tool to see what different focal lengths look like. The tool is meant for DSLR cameras, but it will give you a basic idea of the difference. You need to select both "FX format" boxes, and use the slider to change the focal length. The HX9V has a 384mm equivalent lens; I would guess your current camera is around 250mm:

Good link

That looks to be a good link and given you can get all the specifications on the cameras you are interested in, a great way to get down to a short list.

Specifications are great if you understand what they all mean (not always obvious in the optical world) but I've found that once you have a short list, the best final decision is to go and compare the actual cameras in the photo store. The assistant might even be able to suggest alternatives you hadn't considered.
