    Lens Comparison on 4x5. Symmar, Imagon, Aviar....

    All photos on 4x5 with Delta 100 in the studio. Light on the background had to change on a few of them, as I had to remove one light from my powerpack to get enough light. I replaced the background light with a speedlight in a small softbox.

    300mm Imagon no disk:

    Thanks so much for these, Peter. I found it interesting that the flared highlight in 300mm Imagon small disk holes open is an image of the lens apertures. It makes sense. I've not managed that yet but will be attentive now.

    I agree. This is very helpful - thanks Peter.

    My favourite is the soft disk (H5.8 - 7.7 ??) with holes closed.

    This is a 10" Veritar at f/6 and one dot. Delta 100.
