just got the wd58

I haven't had time to shoot with it yet. I'm floating the Chulitna river tomorrow (a med/small river in Alaska) and taking my Gl2. If I take the 58 I'll let you know what I thought of it. At first blush it's quite the imposing piece of glass. I doubt I'll be screwing it on while I'm floating; too many rocks to navigate and my pelican will be configured to have the 58 unmounted. But when we camp, if the weather will cooperate, I'll try to get some video. I don't have a rain jacket for it. We'll be out 5 days so I'm crossing my fingers for one good day since it's pretty rainy right now.

Kenko 0.65 Bayonet

I recently bought the Kenko 0.65 bayonet from Tristate for $159. You can zoom through, but I wouldn't use a filter as well. BTW I didn't notice a perceptible degradation in my IS. My initial tests are very good, very sharp as far as I can tell. I'm real pleased with it. Thats my two cents.

Don, you think that the the adapter may change the calibration factors for the VAP action yet to all intents and purposes the VAP OIS is insensitive to the outside world. So much so that (unlike EIS systems) it'll work just as well in *total* darkness.

Work? Yes, all that's happening (as Andre points out) is that the camera is measuring the movement that is being applied to it. With these measurements on board it vibrates the front element of the VAP by pushing and pulling at the glass in two locations - bottom and side (90 degrees apart). So if you rock the camera in a vertical motion down at the back and up at the front (as you could by tilting on a tripod say) then the VAP will push the bottom of the front element in towards the camera body to compensate.

The OIS doesn't know or care that you have a wide-angle or a telephoto or a fishtank full of water attached to the camera - it vibrates that front element just as it always will with SSSS turned on.

It reacts with such amazing speed that it alters the prism's shape in sync with your camera shake, in time to bend the light that would be heading off to another part of the chip to be seen as shake. It is for this reason that I refer to it as the closest thing to magic that you or I posess.

DIY lens

go to www.neilslade.com/lens.html

This works perfectly fine, and by varying your zoom, you can adjust the wide angle degree.

Works for the GL1, GL2, and any other camera of this size.

DIY WA lens

$40 for an excellent lens you put together yourself in an hour.

The idea of zooming through the whole focal length using a WA makes no sense to me.

Just take off the WA !!

Many folks have successfully made this and were quite happy with it.

I'm a fellow that needs this ability. I'm regularly tape martial arts sparring in a 15' x 20' garage space using a tripod. I need the wide angle lens
to fit most of the action. I simply can not back up outside of the door!. When the guys are fighting in a corner, I need to be able to a nearly full zoom in on the action.

Raynox

I use both a little .3 clip on for my Sony mini mini DV camera and used the bigger clip on .3 for my GL2

both were very satisfactory

barrel distortion is a part of extreme wide angle lenses. The only way to get rid of this-- if you really need to-- is expensive pro software.

But part of the lure of wide angle IS the distortion.

Zoom in a bit for less wide angle effect, obviously

Neil - you say that part of the lure of wide angle IS the distortion. Well it may be for some (skateboarding movies seem to demand it) but for others (Krubrick's The Shining) it sure isn't. I hate it. If I track through a house I do not want to see the door frames bowing outward as I walk through them - it screams 'amateur' and 'cheepie' to me. Horizons should be straight wherever they are in the frame and telegraph poles should be vertical. Maybe it's just me.

Which is why I love the aspheric wide-angles. The Schneider (0.65x) and the Bolex (both difficult to find) give you zero linear distortion, and I have test pictures to prove it.

I ended up getting the Canon's own Wide angle lens with hood and it's a beautiful piece of glass indeed. Only downfall is that it adds some serious weight to the camera.

Neil,

Can you post a still image from some footage from your w/a lens. I'd like to see a side be side with the lens on and off.

Thanks in advance,

Tom

tiffen 'wide' filters and vignetting

Just been kicking around the net recently and saw that Tiffen specifically makes 'wide' filters (I'm interested in UV and polarizer) that are slim (3 mm thick to be exact) so as to hug close to the camera so you can throw a wide angle in front and avoid vignetting. I've got a bone to pick however. At B&H I was reading the description and it read:

"...They do not have a front thread."

What?! If it's designed to go in front of your wide angle lens, then why on earth wouldn't it have threads in the front?

I'm semi interested in getting one, because I'd like to use a UV or polarizer with my wide angle whenever shooting landscapes and the sky. Vignetting is kinda unavoidable at this point with my current UV and polarizing filters. I got duped when ordering my GL1 into getting a 'pro filter set' (crystal vision to be exact) and it's quality is definately questionable.

I'd like to hear if anyone else around has these or has used them and what their take is on them. BTW - I'd be using it with a WD-58....well, thanks for your help/comments in advance!

Hi,

Yeah, you really have to be careful with filters and front threads.
I was sharp enough to look at the picture carefully before I ordered. I thought the B&H salesman should have caught this
because I mentioned I was ordering filters for the Canon WD-58H wide angle lens.

Well, guess what? The Canon WD-58 WA lens doesn't have front threads, either. My Raynox WA has front threads, so I'm able to
attach 72 mm filters.

>"What?! If it's designed to go in front of your wide angle lens, >then why on earth wouldn't it have threads in the front? "

Read your own words, my friend !

Yeah, the Crystal Optics filters sell for anything from $40-200.
The higher prices are reserved for the retail outlets that sell
the camcorders at a lower price, but only as part of a set that
includes the filters.

ahso. Since I know the WD-58 doesn't have front threads I never considered attaching any glass to the front of it. Thanks for the responses guys.
