GS400 lens hood? at DVinfo.net

Oskar We · September 7th, 2005, 08:47 AM

I've been searching for a lens hood for my GS400 but i can't find one! Does anyone know where to buy one or maybe just the name of a model that works?

thanks!

I don't know if the GS250 filter size is the same as that on the GS150,
but here is what I just mounted on my GS250.

Hama 49mm Snap-on Rectangular Plastic Wide Angle Lens Hood with Cap

Also, you'll need a 43-49 step up ring. Without the step up ring, I don't
even see how the hood would attach to the GS250.

For the GS400, there are a number of hoods that work. I recommend 55mm clip ons like Hama or the Konica 28mm hood. Examples of hoods are (click) here.

Wow, that is a great page on snap-on hoods, complete with pictures.
Thanks, Guy. Though, note that an addtional filter ring must be

I just bought a Hama hood that appears to be for the 16:9 apect ratio.
Since I shoot in 4:3, will I have better flare protection with a 4:3 or 1:1
hood ?

Also, the Kama wider hood partially obstructs the reception of the IR remote control signals.

The optimum hood is one that has the same shape as the CCD.

Check out this auction:

http://cgi.ebay.com/58mm-lens-hood-U...QQcmdZViewItem . When I had GS400, I bought that hood and it fits the cam perfectly. Before they were selling it separately, but now they seem to be pushing the filter together with it. Note that you will need some stepup rings, for example 43-52 and 52-58.

What about when one has a wide-angle adapter (eg. I have the Raynox .66x with a 72mm thread)?

Georg Liigand · November 7th, 2005, 09:12 AM

No idea as I haven't tested with an extra lens. I guess the hood needs to go when you are filming with additional adapters :(

Dennis Wood · November 7th, 2005, 10:02 AM

I ended up making one. There were none available in the size and 16:9 profile that I was looking for.

Guy Bruner · November 7th, 2005, 11:20 AM

You can check out the Cinetatics Matteblox or the Kenko RCH085 85mm wide angle hood.

Actually, I was thinking that making one is a very good option. I guess the question is what shape it should be.

I presume that it should be some kind of petal shape on the sides if one wants to maxmise shading without incurring vignetting, but how to actually get the best shape must be a matter of trial and error. Advice welcome...

Thinking about it, it should be possible to calculate mathematically the shape. Perhaps I'll have a go at that.

So probably best to prototype something in cardboard and then build the real thing from some kind of durable plastic before spraying with the mattest of black paint to prevent internal reflections?

Later: Of course the petal shape only applies for parallel-sided hoods. The way to go here is a pyramid fustrum shape which should be easily calculable.

Dennis Wood · November 8th, 2005, 01:01 PM

The ideal shape for 16:9 is a rectangular hood in those proportions. Bigger is better. You don't need math (although I did use Visio for my templates). You can use paper to create a mockup to check for vignetting at full wide. In my case, I used mouse pad material with ballistic nylon glued to it (fabric spray glue). The hood is sewn on the seams with velcro being used so it can be collapsed. Stiff plastic is inserted along the outer rectangle to keep it stiff. I have a 72mm UV filter with velcro crazy glued on its rim to keep the hood in place. The Cinetactics hood was my inspiration. Works great.

Thanks - sounds good! I've no idea what "velcro crazy" is, but I'm sure I can improvise something....
