As much as it might sound like a stupid question, how do people normally go about attaching the nets to the rear element of the lens?

On the one occasion that I have put rear nets on it was just a case of double sided tape. Normally this is fine, as it just a case of making a neat square of tape and stetching over the net.

However on some lenses it gets a lot more comlicated, particuarly when the glass element is pushed in from the end of the lens, this means attching the net to the inside of the barrel, and can be really quite fiddly, I'm always a bit nervous of damaging the glass, also it is very time consuming and fiddly when it comes to the end of the shoot and you have to take the nets off to return to kit.

Is it always this makeshift, or are there purpose built mounts to take rear netting?

Any help would be appreciated.

Have a look at this: http://store.yahoo.c...lies/iring.html

Looks like a good solution to the problem, but also a very pricey one.

The i-ring doesn't work on every type of lens. I've heard that some people use "snot tape", the type of tape you peel off and leave a gummy adhesive behind (obviously not on the glass portion).

I've seen Nets fixed with clear nail polish. It's not a quick solution, as the polish take time to dry. Removing them just requires some Acetone or Grain Alcohol.

I always use snot tape and it works perfectly. Of the blue-ish, gummy type.

If you want to net the back of an ENG video lens, try the lid from a 35mm stills cartridge case. Take the lid and cut the centre out just leaving the ring. It clips perfectly around the metal barrel at the rear of the lens. You can use it to secure a stretched net and trim away the excess.

I always use snot tape. I've never had a problem, good and cheap.

Unless the cartridge cases you're using are different to most, this is sadly not true - believe me, I've tried :-(

I've always used small rubber bands on the back of ENG lenses. Sometimes it can be a little finicky to put on, but it allows a small amount of adjustment of the net. Stretch the net across the rear element, apply the rubber band, adjust, then trim the excess. Once it's trimmed you can't adjust it.

But snot tape is probably better.

I've used snot tape on PL lenses and the i-Ring on ENG lenses.

Snot tape can be found in picture framing stores if your local art supply place doesn't stock it.

Just FYI: I was hoping to mount a rear net on the JVC HDV lens recently, but there was no clearance back there for anything.

I always have used snot tape rolled into a thin string, and then wrapped around the rear element. Some lens designs are trickier than others.
