specification of "Lens filter diameter" or "filter diameter" will have screw-mount threads for doing what you want. If the spec is not listed or marked "N/A", then assume no threads. Generally, the low end of the spectrum will be "N/A". What is your budget?
Which camcorders have you looked at? It appears that all the Canon HF series at canon.com have the Filter Diameter specification and a link to lens add-ons. The low-end of the Sony and Panasonic camcorders do not have the Lens filter diameter listed - but the mid-range and above, do;
As for "decent low light", I've noticed that DV (onto Digital8 and miniDV) handles low light better than the new non-tape camcorders (especially high definition) - but the same rule applies - large lens and large imaging chip make for better low light performance. Once we know your budget, we can see what fits and set the lighting behavior expectation.
Greetings one and all.
For a number of years I used various Sony digital8 camcorders, which I absolutely loved and with which I racked up many 100's of hours of vacation footage, but l developed chronic tendinitis in my elbow and I had to resort to a smaller lighter mini-dv camera.
In all my cameras two things remained constant: they needed to have decent low light ability and absolutely had to have the option of attaching a wide angle lens and or filter via threads at the lens area.
Now, as I consider going to a HD flash memory camcorder, regular consumer grade, I am not seeing any with the lens/filter attachment capabilities.
Surely there are some out there?
I see that some brands have increased the wide angle capabilities of their cameras; but I cant imagine that they equal a dedicated wide angle lens; am I wrong about that?
And how do you add a polarized filter?
Have a Magical Day
