I've not changed mine. I've removed it. You'll have to dig through the polyethylene plastic to find the rivets (4 of them IIRC) and drill them. They tend to rotate, so hold them with pliers from inside the helmet. To attach the new box it should be as easy as riveting it. Carlos Martins Portugal www.cj.smugmug.com

I've been scanning e-bay trying to find one. PC1000 go regularly for 500 Euro. PC330 don't go bellow 400 Euro (Pal, European versions). Carlos Martins Portugal www.cj.smugmug.com

Looks really nice to me but... from the picture I would say that it is impossible to adapt a wide angle. With its zoom to the widest they specify 43.9 mm of focal lenght (@35mmm equiv) so I would say it is not wide enough for freefly (or tandem) video without the adapter.

I'll sell you mine for $143 It is in fact somehow dated, better spend the dough on the Norman Kent DVD. Not a tutorial on how to fly but lot's of interesting stuff fora begginer. Carlos Martins Portugal www.cj.smugmug.com

That is not my experience. I had a 300D which I abused hard. Skydiving was its lightest duty. No protection whatsoever, salt water/mist, motorcycle off-road travelling in nasty dusty/hot environments: zero problems besides the flash latching mechanism that gets bent once in a while and that I straighten up with my finger. Sold it with around 20 k shoots to a friend that kept jumping it. It keeps shooting. I now have a 20D, have dropped it on the floor several times, been abusing it much the same way and have no complains, just broke the battery door after dropping it. Canons look flimsy compared to Nikons but mine sure have endured a lot of mistreatment. Carlos Martins Portugal www.cj.smugmug.com

The CX7 is called CX6 this side of the Atlantic. We're PAL. Carlos Martins Portugal www.cj.smugmug.com

Hello Birds! Anyone found a way around the WBT-201 limitation to internally store loggings at more than 1 Hz? Thanks in advance, Carlos Carlos Martins Portugal www.cj.smugmug.com

Hi, Just FYI, although there is indeed an EF-S 18-55 IS lens, Canon's standard kit lens is still the non stabilized version. At least this side of the Atlantic... Carlos Martins Portugal www.cj.smugmug.com

Why do you say so? Just curious, as I really like my Peleng - nice colours and definition. Although this Sigma is probably a much better value at 450 USD - auto-iris, auto-focus, warranty... Carlos Martins Portugal www.cj.smugmug.com

The board is probably varnished. Scrape or lightly sand the board at the places you intend to solder till the metal looks bright. Then use a bit of soldering flux. If your soldering iron is BIG beware not to overheat the components on the board (or the board itself). Carlos Martins Portugal www.cj.smugmug.com

I did order my Rawa with their mounting system and it is not similar to a Schumacher or Goldmember. It's a 2 mm aluminum plate that bolts to the camera with a countersunk screw. This plate has a sort of rivet on its underside that slides in a keyhole shaped slot on the helmet top. To the rear of the backface of the camera the plate protrudes a bit and two Allen screws attach there to the helmet. Inside the helmet there's a steel plate with the threaded holes for the two screws and the keyhole slot. I am describing this by memory, a photo would certainly be more eloquent In my opinion the mounting system doesn't do justice to the excellent quality of the helmet, not even considering the very low price.

Sorry for the off-topic, but what's the usual skydiving use for that range? canopy work? I've been toying with the idea of flying a 50 mm (Canon's cheap, lightweight 1.8) but my camera has a 1.6 crop factor so it would work as an 80 mm.... Carlos Martins Portugal www.cj.smugmug.com

, Huh? Not unless you realign it, right? Carlos Martins Portugal www.cj.smugmug.com

First Universal Imperial/Metric Schumacker

yes... my first idea was to fill the 5/32 holes with epoxi or something then drill and tap. But then I just drilled new 2.75 mm holes close to the original ones and tapped them to M3. I'll post a pic tonight. Now I have a metric (read correct) Shumacker. Carlos Martins Portugal www.cj.smugmug.com

Yep, we're metric here also (as everyone should ) I've drilled new holes and tapped them to M3. Carlos Martins Portugal www.cj.smugmug.com

Thanks! I just received mine (very fast shipment, BTW). I just watched a random chapter, Norman Kent describing _his_ deployment procedure. I am thrilled! For me the investment is already worth. I can't wait till I get to see the rest. Carlos Martins Portugal www.cj.smugmug.com

Hello, I can't find anywhere on the site how to order this. Can anyone help, please? Thks Carlos Martins Portugal www.cj.smugmug.com

Considering the price of a Gath helmet and the price of a quick connect system (like a stroboframe) you are better off just buying another helmet. And you can make it much more secure/safe with a permanent attachment. JMO. Carlos Martins Portugal www.cj.smugmug.com

I though something like that got called a tandem Carlos Martins Portugal www.cj.smugmug.com

Hi, Without searching I dare to say that the multiplying factor stated on conversion lenses is to be applied to the focal lenght of the main lens and not to the linear dimensions you get to see through the lens. There's some added confusion because conv. lenses are mostly used on video cameras, and these state their zoom range in X times. Your camcorder zoom is equivalent to, say, a 32-500 mm zoom lens (35 mm film equivalent), so, a conversion lens of 0.5 would make it behave like a 16-250 mm zoom, but the relation between field of view and focal lenght is not linear, AFAIK. Add to that the usual manufacturers bullshit and no one knows for sure if this conversion lens is widder than the other. I remember founding a link on the internet some years ago where a skydiver compared some conv. lenses and the widdest was a 0.6 Sony (I believe he was comparing with at least a 0.45 from some other brand. Of course we could all measure our gear in some simple and standardized way, say, this camera, zoomed to widdest sees X linear wide dimension at a Y distance, and with an XPTO brand conversion lens, that linear dimension increased to Z. Better yet, we can scavange the internet and find someone who already did this

Here's a reference for you: A 15mm Canon EF lens, on my 20D (that I believe has the same 1.6 crop factor of your XT) can see 99.5 cm (39.17") wide when facing a wall at a distance of 65 cm (25.59"). I am measuring the 65 cm to the film plane index of the camera (there should be a smililar mark on you XT). Now, just face your PC against a wall at a distance of 25.6 inches and see through the viewer how much wide across the wall you can measure. Am I making any sense? Prolly not! Better upload a pic.

I've seen both in the flesh and they're two diff animals. It's like comparing apples and oranges. Cookie is skydive specific. Like a Goldmember or a Schumaker it was designed to be the lightest, lowest and snagleast (hey! I invented a word!) while still being strong enough and precise enough. RRS was designed to be the most precise and strongest possible. It happens to still be light and low enough to be good for skydiving. JMO, YMMV, etc Blue ones Carlos Martins Portugal www.cj.smugmug.com

I used a plastic juice bottle as a mold to create the top and lateral sections. The bottle is a quadrangular prism with round edges. I laid a thin layer and cut the necessary portion of that with scissors as soon as it was touch dry. I used a Dremel to rough the helmet finish at the attachment points and glued this piece to it. The rear part was then directly laid. Sorry, I made no pics of the building process... my hands were too sticky to pick up a camera Carlos Martins Portugal www.cj.smugmug.com
