Going from bayonet to screw mount filters and lens hood

[ewgrow]

Hi all. I've decided that the cheapest way to use filters and a lens

hood (at the same time) on my Hasselblad 80 C lens is to get a step-

up ring so I can use screw mount filters with a screw mount lens

hood. So, two questions:

 

1. What size should I go to in order to find the cheapest and most

wide selection of filters? 52mm? 57mm? (my lens is B50)

 

2. Having decided #1, what lens hood should I look for and how long

should it be in order to not have vignetting with an 80mm lens (yet

still cover an adequate area)? I'm thinking cheap here--to me a lens

hood is just a piece of plastic that blocks the sun.

 

I've heard a bit about Lee systems and whatnot in some of the other

threads. Would I be better served with something like that? Thanks

in advance to all responses.

I assume you don't have a hassy hood already. If you did it would

fit over the bay to screw adaptor.

 

I have a chrome 80mm lens. I use a Hassy Hood and a Tiffin 57

bay to 55mm screw adaptor.

 

Do you have any filters already ? If so you could try bay 50x?

whatever size you have the most of and check for vignetting.

My own opinion would go for 52mm, since that is an old standby size for Nikon (and others) so that there is a good selection on the used market. 57mm is also fairly common but could be slightly more expensive. If you intend to get a WA lens, then maybe 57mm would make sense.

 

Just test the lens shade by mounting it. Point the lens at a bright object (the sky) and stop the lens down all the way and see if the shade intrudes into the viewing area. You can also move a finger gradually in from the perimeter to see when it becomes visble and give you an indication of your "safety" margin.

A Lee adapter and compendium shade isn't the cheapest solution initially, but can be expanded to fit all future needs with very small extra cost. All filters can be used on all lenses, regardless of filter thread/bayonet. It certainly gets my top recommendation.

You are smart enough to ask this question as the B-mount UV lens or PL lens or the hood is extraordinary expensive. My experience for 80mm and 180mm lens is to buy a B60-67 screw adaptor. Use 67mm UV and PL lens. Buy a HOYA rubber hood (67mm thread) to screw onto the filter thread. This HOYA hood is the type that can be retracted and extended according to different lens. So, one hood for both lens! In addition, if you use this approach for PL filter, you will find it is very easy to turn the PL lens by the rubber hood ! YOu don't need to dismount and mount the hood.

I say this because if you use B-type PL filter with Hasso type hood, you have to dismount hood, turn the PL, mount again hood before you can shoot. This is tedious.

Thanks for the good advice, everyone. No, I haven't any filters yet, so I'm starting at

square one. Sounds like I should go with a B50 to 52mm adapter. I don't think I'll be

going any wider than the 80, since I tend to like shooting slightly long. Norris, does

Hoya make that rubber adjustable lens hood in the 50-57 size range? Maybe that

would be a good buy. I don't think a Lee system would be right for me, because I

really don't see myself getting much more than a handful of filters-enough to worry

about the cost, but not enough to make that system cost effective for me.
