Re: [videoblogging] Re: question about wide angle lenses
Quality varies wildly with these, esp. when you get into the smaller (wider) multipliers. I would stick with the more reputable brands (Century Optics, Canon) unless you have the chance to try before you buy (or a source with a great return policy). Since they aren't actual lenses but rather lens adapters, also remember you are adding another piece of glass to your whole lens assembly (with your existing zoom already wide - meaning more of the surface of the lens in focus) so keeping things clean and the aperture as open as possible becomes crucial. OTOH, the weird distortion from the cheapo brands can be great for those of us who like the option to turn our camcorders into video Holgas/Dianas/Lomos when the mood strikes.

[videoblogging] Re: question about wide angle lenses
The lens I use is a .45 and it's pretty good because I don't get a lot of vignetting around the edges which can be a problem with some of the cheaper lenses. Of course it probably helps that I got a lens that was too big for the camera and use a step ring to attach it. My camera has a 43mm threaded lens and thats an odd size so there aren't too many options for lenses. So I got a 52mm and use a 52 to 43 step ring (cost about $8 or so) to connect it to the camera. Works great. A wide angle lens is definately one of my must have accesories ... That and a monopod. One other advantage to shooting with a wide angle lens besides making it possible to shoot in smaller spaces is that it makes hand held shooting seem smoother because the camera movements aren't quite as pronounced as when you are shooting through a telephoto lens.

Telephotos are messured in number of times of magnification 1x 2x 10x etc. So wide angle lenses are the same. Only they are magnifying in reverse.

[videoblogging] Re: question about wide angle lenses
Some lenses blur our when you zoom in a lot. I have a .7 that does that and a .5 that doesnt. I would assume that with macro means full zoom through.

[videoblogging] Re: question about wide angle lenses
around the 1/6/07 Heath mentioned about [videoblogging] Re: question about wide angle lenses that: Also some wide angles say with macro and some don't what's the differance? macro lets you do extreme close up, like filming bugs, flowers water droplets etc. this is when lens very close to subject (as opposed to long way away and using a big zoom lens) and most lenses can't focus that close. so good if you want close ups of things that you are close up too :-) -- cheers Adrian Miles this email is bloggable [ ] ask first [ ] private [x] vogmae.net.au
