Lens hood plus oversized filter

[Macnew]

Currently I have an oversized variable nd filter (b+W) and I'm wondering if I should use a lens hood and if so how? Can you buy larger lens hoods? As currently putting the lens hood on first then attaching the filter is too difficult (the second stage attaching the filter I mean).

Any advice is much appreciated, thank you

Rubber lens hoods are available in all standard sizes from many places. Here are some from eBay.

By oversized you mean you have a stepup ring? But then your hood would hardly fit so I don't quite understand your situation. Anyway you can attach a screw-in hood with the appropriate diameter. That's what I do. I have stepup rings on all my <52mm thread lenses so I need only one filter size. With metal and plastic hoods you need to search for a suitable length. As threads differ you are probably stuck with circular hoods which are of course never quite as effective as petal ones which are also not optimal on zooms except at shortest FL. Still much better than no hood. You can buy a bunch and try them out as they hardly cost anything on eBay. Rubber hoods are flexible as they have 2 positions which can be useful on zooms and taking pics through windows (cut out some reflections). They can also take less space.

Check out XUME magnetic filter holders. Note that if your lens is wider than 35mm on a full frame, you’ll need a step up to the next size to avoid vignetting.

This is true. i'm not fond of rubber lens hoods, however, and you should exercise care in finding a size that won't vignette with your combo. This is especially problematic with wide angle lenses.

That's exactly what I've done. On my Nikon 24 - 85mm, the 72mm filters will vignette at anything below 38mm with the XUME adapters. So I use a 72 to 77mm step up ring and just use 77mm filters with the XUME adapters. All this works with the standard lens hood, so I don't have to worry about knocking the magnets off.

If you think about it, a lens hood has two functions

• protect the front element from bumps and bangs
• shade the lens from direct light that can cause flare (or loss of contrast, called 'veiling flare)

You can deal with the second issue just by shading the front element of your lens. You might more to shade, or have an assistant hold, say, a hat so it shades the lens. If the camera's on tripod, you can block the sun yourself, The cinema guys have something called a 'french flag' (works just like the 'barn door' flaps on a stage light) but those cameras have a cage, with easy mounting points for stuff like that.

I've seen a few shade flaps designed to attach to a camera hotshoe with adjustable arms of gooseneck. Dinkum Systems makes the gooseneck style, GlideGear the arm style.

Neither of these protects your front element. I think you're stuck with a screw-in hood for that. I haven't used the magnetic filter attachment system, but I'd question how much protection a magneted-on hood might provide.

When I bought a variable ND, I wasn't aware that it had the built-in step and I've always used lens hoods.

With an empty filter ring added, I can manage to fit it inside the bayonet hood that I normally use for the few times I have used it. I can also mount it "inside" a collapsible rubber hood that I already have and just add it to the lens.

Personally, I'd like to find one without the step and just replace it.

Hello, thanks for the response(s). Not sure how to format this as the reply will cover multiple replies!

I'm using a sigma 18-35mm lens. The lens hood supplied, I think offers more protection than a rubber lens. but still may try the rubber hoods

I like the look of the adapters and should work for me however I think the filter may be too far recessed into the hood for me to pull it off with the magnetic system.

The variable filter is a 72mm thread but to prevent vignetting its slightly larger so the outer thread is 77mm.

I have asked another question: https://www.dpreview.com/forums/post/61297601

maybe in combination, I could reach the filter? or even unscrew the lens hood and use it to pry the magnetically attached filter?

I also have the concern with adding too much on the end of the lens (adding space/air) as I can see this magnetic system adds effectively another filter of space.

thank you for the help!

If you Sigma lens hood is the butterfly style, then you should have no trouble reaching in with your fingers to pry off the magnetically attached filter. It's not that hard to pull off. You just need to be able to get one finger on the edge to flip it off.

I personally love the XUME system. I find myself using filters more often.

The hood would not use the magnetic system. Only the filters.

My lens is 18-35 72mm and my variable nd filter is 72mm so I can't step up. Do you think I'll get vignetting? Crop sensor nikon

18mm on a DX would have an angle of view similar to 28mm on FX. So, yes, I think you would see vignetting.
