    4x5 lens that "swirls" ?

    Is there a lens known to "swirl" on a 4x5?
    There seems to be a lot for the 8x10, but of the barrel lens I have tried on my 4x5 Sinar f2, none seem to "swirl".
    By "swirl", I mean like the images produced from the "legendary" Russian 85mm f1.5 Helios 40-1 for 35mm systems.
    Which is still on my wishlist of items to purchase.
    As lot late, I am focusing more on my 4x5 system.
    Thanks.

    Could you provide an example picture from that Helios lens?

    Sounds like you need to look for a short FL Pertzval lens meant to cover something like a 1/8 th plate maybe a 4"or 5"FL.

    If a Petzval lens is under sized for the format it will produce dark corners and will swirl the boarders of the frame. It will show up much more so if you have a busy background .

    You may want to do a search on" lenses with swirl" or" Petzval lens with swirl". Plenty said on the subject.

    Here's a post with some extreme examples of Petzval swirl.

    Photoshop's Radial Blur filter followed by some careful use of the History brush will save you a lot of money and hassles ;-p

    Thanks for this information.
    Seems like the Petzval swirls are MUCH more pronounced than the various 35mm lens swirls.

    Hmm, there were a bunch of Helios 40 85mm f1.5 examples on Fred Miranda Alternative forum, i can't seem to find them right.
    Will search later.
    I did find one good example from the Manual focus Lens Forum:

    Vaseline on a lens filter is great too.

    It depends on the FL of the Petzval lens and the plate size it's used on. So a 8-9" Petzval will hardly swirl on a 4x5 plate size .

    It also depends on what distance your focused at. For example, you get more swirls the closer to infinity your focused and less when your focused at Portrait distance.

    Here is the particular Helios 40 85mm f1.5 example I was thinking of:

    Perhaps some projector lens would do?
