I am just curious, what do you use?
a) Sinar shutter
b) packard shutter
c) lens cap

Speed graphic or lens cap.
All of the above except the Sinar.
Any reason, Jim? (Aside from not having a Sinar/Horseman, that is!!)
I'm considering using one of Sinar's Auto-Aperture shutters in conjunction with a Brass/Petzval et al to give best control of shutter speeds. In a pragmatic sense, this is way more functional and accurate that a [single speed] Packard.
Thanks in advance,
Lachlan.
Luc shutter with strobe sync added.
Speed Graphic shutter, Packard or soon when I've restored it a Thornton Pickard Instantaneous shutter (roller blind).

Packard...
Songyun, I don't know if this will work for you -- vignetting may be a problem -- but I have, even use, lenses in barrel with focal lengths ranging from 4.75" to 480 mm that I use front-mounted on a Copal #1. But I shoot all of them on 2x3, not 4x5.
I use my shorter barrel lenses (44 mm, ~100 mm, and sometimes 12"/4 tele) on a 2x3 Speed Graphic. These lenses have too short back focus to be front-mounted and still make infinity (44 mm) or cover 2x3 (the others). The 44's good only for 6x6.
Most of my mount adapters (lens-to-#1) were made by SKGrimes. Not as much of an economic disaster as you'd think, there just the one shutter and most of the adapters accept more than one of my lenses.
I would use a Sinar mechanical shutter, still looking for a cheap one...
I'm not in a hurry though.

I've never compared side by side but I've had the Packard and the Sinar shutters and I think the Sinar vibrates the most of any shutter yet. I doubt it matters most of the time but for long lenses there might be one or two speeds that match some weird frequency of vibration (I don't know, I am thinking in tuning fork terms...)
If you practice I think you can make a lenscap work at 1/2 or one second and longer....
