Ah, I see ... "rifle sight" is a pretty good description actually :-)

The sight I drafted is similar to the old "sports viewfinders" (if the German term translates) used in the mid-20th century, only that with the short focal lengths then in use, the old ones were often visibly pyramid-shaped, opening out to the far end.

Regards,

Henning

TS writes "- It should still be a good camera with telephoto lenses, able to take high quality pictures (not just documents). "

FZ1000 is an interesting suggestion, good value for money considering that the IQ seem to be quite close to a D300s (and 350D) with good IQ up to ISO800. The weak point would be the lens (could be sharper at 400mm) and durability (not weather sealed).

The definition of "high quality pictures" is of course subjective but for publishing pics on the web and print smaller sizes, the FZ1000 would be fine. If the budget is larger, I would probably go for a more conventional DSLR, but the cost could easily triple.

Coincedentally, this is what my FZ1000 looks like at the moment:

I actually bought the (cheapo) scope for mounting it on my birding scope, but as it fit my camera, I just put it on to see what it looks like.

When I just picked it up and actually adjusted the sight to match the sightline of the camera, it became apparent that at 400 mm, the margin of error is not very big if you want to keep a bird in the frame.

(The scope has a 4x magnification with a wide eye relief and gives a pretty good view for the purpose. I didn't expect to use it on the camera as depicted, but except for its bulk and weight, it appears to be quite a functional setup, to my suprise.)

Regards,

Henning

You can bring different subjects into focus one after
another.
[-] side: The camera waits for a short period of time
before re-adjusting the focus. This allows you to
prevent the focus from being accidentally re-adjusted
when, for example, an object moves across the image.
This item works only when the Focus Mode is set to [AFF]
or [AFC].

Thanks for the advice, I'll give it a go...I definitely need to put the time in to learn the menus.
