I need an extra wide lens

[PatrickMarq]

Just a reminder that your Chamonix 45F-2 has asymmetrical tilt on the rear standard if tilting the front becomes an issue.

Thank you for the reminder Alan, sometimes I forget this. Don’t use a lot of wide lenses.

I completely did not think about a center filter. I have one for the 90mm

The one for your 90 will still help, try it with a step-up ring.

I have a center filter for my 90mm. Will it help with my 75mm?

Speaking from experience with the 65/5.6 Super Angulon on a 45F-2, it will focus just fine and is entirely usable with the universal bellows - bag bellows or a recessed lens board are by no means mandatory. At infinity focus it's pretty tight, but if you're shooting indoors you may be focused a bit closer than infinity and will gain yourself some extra wiggle room.

If you plan to use significant movements the bag bellows would be ideal, but if you only plan for minor adjustments the stock setup should be just fine.

I have photographed a number of buildings with wide angle lenses. I use a 90mm, 75mm,and a 135mm, mostly. Often for interior views, and for situations where there is only enough space to get the image from a certain angle. For tall buildings I most often use - front rise. The wider the wide angle lens the more distortion there can be toward the edges - especially noticeable with rounded shapes.

Not a problem with that lens, since the image circle limits movement to next to nothing -- as other responders and I have already mentioned.

Yes, as long as the pupil tracks across the filter as you go off-axis, there will be correction. Depending on how much bigger the filter is than standard, you might get 1.5 stops, or even 1 stop correction, from a 2-stop filter. The exposure compensation will be as stated for the CF because the attenuation in the centre is still the same. My guess is that you'd get around 1.5 stops from a 2-stop CF, from this combination.

I've found it to be almost mandatory with anything wider than 90, I've never used one on a 90.
