ileax acuton 150mm f/ 4.8 problems

[jzeairs]

i just acquired this lens with my camera and have been using it for a few weeks. all shutter speeds work fine just not the bulb. so no long exposures or night photography which is what i enjoy doing. does anyone know why this could be? the only other switches on the lens is to toggle between X and M. this has no affect on the bulb setting. any help would be nice.
thanks

X or M refers to the flash synch, X is for electronic flash and should work at all shutter speeds. M is for flashbulbs.

No T? What make of shutter is it?

[Fotoguy20d]

It needs a CLA. I've seen many shutters (of all different makes) where speeds work and T and/or B do not.

yes it has T. also how much is a cla? i really like the lens so i think its worth it.

[Fotoguy20d]

Is it a Copal or an ilex shutter? Not that it matters for cost. You'll find lots of discussion here about where to go for a CLA. I use Carol Miller(Flutot's). You'll find her website without too much trouble via google and it should have the latest cost info and how to get on her waiting list. I just got two shutters back from her (copal1 and Ilex5) and immediately went back on the list for two more. You'll wait a long time before even getting them out to her and she doesn't work quickly but I've always been happy with the results.

Carol is incredibly reasonable on price, super nice and well worth the wait. flutoscamerarepair.com

I can't vouch for the other shutter repair shops. I have been using Flutot's camera repair since the early 80's. I am fortunate that it is only a short drive over the hill for me.
