240-300 lens for 8X10 wide open... Bokeh ?

[archivue]

Usually i shoot around F22, but for a project, i will shoot in 8X10 wide open... looking for a narrow deph of field, and a nice bokeh...

Any suggestion regarding lens around 240-300 mm ?

Nikkor 240W.

I've got very nice images with my Nikkor 240 mm W wide open.

Tessar (http://www.kenleegallery.com/html/tech/hydrangea.htm) or Heliar (http://www.kenleegallery.com/html/tech/rosev.htm)

With those lenses, you don't need to shoot wide open to get good blur.

12" Wolly Velostigmat in a studio or Betax #5 shutter. At 4.5 on a 10x8 it is wonderful. See Jim Galli's site.

I've got a 12" Gundlach Radar with an aperture of f4.5 (in a Betax #5, like steve) that seems to do pretty good! f4.5 is pretty fast for an 8x10 lens! How far away to you plan on focusing?

Ken, that is a lovely shot with your Heliar. Which heliar did you use? 300mm non-universal heliar? Jon

That's the point... around 3 to 5 meters in sunny places... i will probably use a 6x neutral filter to do it !

The think is that i want very limited dof... but i want sharp details to be very sharp !

Similar to Zeiss-contax lens in 35mm.

You may want to take a look at some of the older brass lenses as well, some of them are quite big around! I don't know much about them yet (just getting into them myself) but I've seen some in the 300mm+ range with good sized apertures! Some of the brass lenses seem to have a very nice look to the blur!

I use ND filters during the day as well, to keep shutter speeds down when I want to shoot larger apertures.

That one was made on 4x5 with a 150mm Heliar, and not wide open either. The lens design, plus the many-bladed aperture, give you good blur at all settings. You can control the depth of field, knowing that whatever is blurred, is nicely blurred.

This works for distance (http://www.kenleegallery.com/images/larger/4.jpg) shots as well. That image was made with a 210mm Heliar, stopped down to f/8 or f/11.

Without this forum, I would have never learned about stuff like this.

241, 254, 302 Wollensak f/4.5 Raptars or 10", 12" Kodak f/4.5 Ektars. Heliars are wonderful but may vignette on 8x10.

Have fun with the hunt.
