Hi
I'm looking for a ND filter for a Hasselblad 28mm lens, thread size of 95mm. Considering a heliopan 5 stop with a 105 step down ring. Any advice on problems with vignetting or other systems would be appeciated.

If you are using Lee filters, they make a 1, 2,3 and 10 stop. You don't get a lot of choices before vignetting starts with the Lee systems on a 28.

I do have a Lee holder but would need a stepper ring to bring them up to 95mm. Can't see how to avoid cut off with this option though.

Hi Shaun
I use the Lee filter setup on the 28 and 50-110 lenses, and the others but they are mainly smaller diameters. Although I get the desired results, on the 28 and the wide end of the zoom I do get vignetting even when only one filter is in place. I have found that using just the filter against the front of the lens and no attachment/slots. but hand holding the filter or using blutac, I don't get the vignetting but of course it is more difficult to make minor adjustments.
It works well with a bit of practice and is now my preferred means of using these filters on a large diameter lens, the 300 HC as well. I hate the undesirable vignetting ruining a picture.

Hi Richard
That sounds good to me, thanks for the feedback.

what about using a step-up 95mm ring to this?:

LEE 14-24mm filter holder. the filters are 150mm wide(6") instead of 100mm

Hi
I struggled to find a solution to the problem with my 28mm.
Talked to Lee, hasselblad and a whole bunch of people in the UK. The final solution, which works very well and eliminates any vignetting, is to buy a Cokin 95mm adaptor ring and X-Pro filter holder and then buy the Lee X-Pro sized filters; the ND filters are 130 x130mm and the ND grads are 130 x 170mm. Both are priced at £63 in the UK from Robert White.
Hope this helps.

B+W has an 95mm Extra Wide. This is one way to go.

I guess its only 2 stops though.

I use this and it works great :

Hi
Lee Filters do a push fit filter holder which works well with the 28mm lens. It takes one filter and there is no vignetting. I used to have the Cokin system but found it too bulky and in any case I prefer the Lee system. The push holder locks on to the outer rim of the lens and fits well and reasonably securely.
Best wishes
