Hi guys

I have been using Xpan and 45mm for some time and have recently ordered a 30mm lens that comes with a centre filter

From what I read, it seems that the centre filter for 30 can be used on 45 as well - can anybody confirm that for me? thanks

It would be really nice if I can save some money on the centre filter for 45 as I think I will just use it rarely... (and have just spent big $$ on the 30 :()

Thanks for your time

Zane
 
I have both the 30mm and the 45mm. The 30mm has a 58mm filter size, while the 45mm uses a 49mm filter. So in order to try the 58mm center filter on the 45mm lens, you will need to shop for a 49mm to 58mm adapter. This would of course make it not possible to use the lens hood. Another issue is that since the 58mm filter is larger in diameter, the denser part of the neutral density area will then extend farther into the edge of the front element than it was meant to, while the lighter area will go unused. That will truncate the range of densities the lens sees as it looks through the filter. In other words, it might under-correct.

Do you really feel the need for a center filter with the 45mm lens? I do not; with Provia, I do not get significant vignetting. I'd say it's more trouble than it's worth.
 
From the following spec, it seems like all filter sizes of the three lenses are 49mm

But I don't understand why the centre filter for the 30 lens is 58mm??



Hasselblad 30mm f5.6 Aspherical: bayonet fitting , f5.6 - f22, 8 components, 10 elements, multicoated, focussing range 0.7-infinity, filter ø 49 mm. Angle approx. 17mm lens in 35mm camera terms when camera set at panorama format (supplied together with a bright optical viewfinder with built-in spirit level and field markings for regular and panorama formats and a dedicated 58 mm centre filter).

Hasselblad 45mm f4: bayonet fitting, f4-f22, 6 components, 8 elements, multicoated, focusing range 0.7-infinity, filter ø 49 mm, Angle approx. 25 mm lens in 35 mm camera terms when camera set at panorama format.

Hasselblad 90 mm f4: bayonet fitting, F4-F22, 7 components, 9 elements, multicoated, focusing range 1.0-infinity, filter ø 49 mm. Angle approx. 50 mm lens in 35 mm camera terms when camera set at panorama format.
 
Thanks Rob... so the 30 lens has a 58mm thread

I think you pointed out the right issues

I have used the xpan and 45 for about 6 months, I didn't really feel the need for a centre filter until I used Velvia for a every evenly lit after sunset scene and the edges are darkened a bit...
 
I've never had any issues with vingetting on the 45 without a filter.

However, does anyone have any comparisions between shooting the 30 with and without the filter?

I have the filter, but shooting at F11 equiv. really kills me... I'd love to see some examples of how dramatic it was [esp on slide vs neg]

I have shot it with and without, I prefer the with versions.
 
the vignetting on the 30mm WITHOUT the filter is very dramatic. especially if using color film.

you will definitely want the filter on the 30mm.

you do not need the filter for the 45mm unless shooting color film.

Thanks for the insight. Looks like I'm sticking with f11 for a while longer ;)
