I like a bit of bird watching, me.

I have tried digiscoping but it's a right old faff about.

I have seen new digital cameras with 24x optical zoom, this seems incredible, are they any good?

I understand I woold need to use a tripod.

Can't get into digital SLRs by the way.

Thanks.

The 24x relates to the multiplier of the shortest focal length, so it it's a 10mm at it's widest, then 24x means it's 240mm which isn't that great for bird watching I'd guess.

If the camera is 20mm at it's widest then you are talking 480mm which is much more like it. I'd imagine it would be very wobbly though so you'll definitely need a tripod or some other form of support.

For twitching you need binoculars.

I recommend a set of Canon Image Stabilising ones. You'll spend money on 'em but they're worth it.

Thanks for replying guys.

I already have binos and a scope, it's just the picture taking I need to improve.

In order to get shots of birds you are going to need something with LOTS of magnification and the means to attach a camera to it.

You say no DSLRs but you can get adaptors to connect one to your scope. If you google Nikon and Digiscope you should find something.

The alternative is to get a DSLR and a whacker of zoom lens. Trust me - I have a 400mm lens and it's only good enough for shooting in the garden, really. Bigger telephoto lens = much bigger bucks.

I have heard of binocs with a digicam built into them. You could try Googling for that...but I don't anything else about them...

In that case, and if you cannot afford/don't want an SLR camera, then yes, a camera with a 24x zoom lens or similar is probably your best bet.

As explained above, the '24x' bit is telling you about the overall zooming range of the lens. The important bit is what is the focal length at its greatest.

This will be expressed either as the actual length, or as the 35mm equivalent focal length. This is because how wide or narrow an angle of view you get for any given focal length depends on how large (physical dimensions, not number of pixels) the sensor is. So an actual 50mm focal length can give you a different angle of view on different cameras. The 35mm equivalent focal length gives you a way of comparing cameras with different sized sensors by telling you what the angle of view would equate to on a 35mm film camera.

Finally a camera with a 250-500mm 35mm equivalent zoom lens has a 2x optical zoom but will still give you a narrower angle of view than a 28-300mm 35mm equivalent zoom lens that has an 11x optical zoom. Hope that all makes sense to you.

Why am I reading that as if hearing it in a dodgy cockney accent in a quiet corner of a pub somewhere...from a big bloke referring to the local lap-dancing club! wink

I'm waiting for the f1.2 version personally... hehe

I have a Kenco tele conversion lens x6.5 KUT -65 that converts a 35mm equivalent to 3,120mm when shooting video.

Something thats 500-600mm equivelant and shart at f5.6 is whats needed regardless.

Anything less than about 400mm real is too short.

I've been using mine with a 2x. I'm so manly I've been shooting handheld at (if you consider the crop) 3480mm wink

You must be built like a gorilla! wink
I bet it's a touch slow with a 2x TC though...!
