I'm sorry to bother you all with problem that seems to me should be

so easy to resolve, but I have been searching for two days to find a

user's manual for my 540 EZ Speedlite. If you could direct me to a

site where I can download one, I would be very appreciative. This

is by far the most advanced flash I own, and at first glance seems

to be a really cool flash. I can't wait to try some multiple

exposures with the strobe! Thanks, Brian.

That's right. You can leave the lenses on automatic all the time for the T70 and T90, but you should never put it on Auto for the FTb. It does not matter if they are the old or new FD lenses. Have Fun, Brian.

Everything said above is true, but I can tell you for sure if you have to worry about it or not if you tell me what kind of camera you have.

Also, DO NOT try to put the ring on O and try to mount it on an FTb. Something could get damaged, and it will on go on incorrectly. An FTb is not cabable of automatically controlling the aperture, so there is no need to set the lens to O, and you can't do it anyway. DO NOT try to force it. Brian.

Thanks Everyone for your help. I will try this out next time I get a chance. Brian.

By the way, I have all of the manuals, but they only touch on all of the many things that a T-90 can do, and do not get into any depth about anything. It basiclly exspects you to set the camera and flash to program and take what you get.

Mark, thanks for trying to help me out, maybe I need to explain a little more. My negatives have good density; there is plenty of light. In fact, the flash was cycling very quickly and was not putting out nearly its full potential. The T-90 controls A-TTL exposure by controlling the duration of the flash, and that is working properly. My problem is that I do not have enough depth of field or my shutter speed is too slow, in this case both is true. I understand that normally there is a trade off between shutter speed and aperture, but in this case it need not be that way because it is actually the duration of the flash output controlling exposure. When I set the camera to AV and the aperture to f 8, it came up with a shutter speed of about 1 second, this caused motion blur. The little lighting bolt was lit up in the viewfinder, so the camera knew it was on a flash and that a 1 second shutter speed was not necessary. It does this to balance the background with the foreground in landscape shots, but I want to override this. So my question is, what setting should I use to get good depth of field and maintain a normal synch speed? It may not be possible, but it is a major shortcoming of the T-90 if it cannot be done. Thanks again, Brian.

I have a T-90 and a 300TL flash. I have been using it in a studio

type situation with the Flash on a light stand and with a small soft

box. It is connected with the proper off-camera adapters and

cables. The camera\flash always sets the lens wide open, but I want

greater depth of field, so I have set the camera to AV and choose

about f 8. My problem is now that the camera sets a long shutter

speed based on the ambient light, which has been causing some motion

blur. How can I get the camera to use a normal synch speed, like

around 90, and also have a good aperture setting like 8 or 11, while

keeping the A-TTL capabilities? I am very capable of doing this

manually, but I would like to use A-TTL if possible. Thanks so much

for any help. Brian.

I once found an AE-1 program with a flash and a 50mm 1.4 lens along with quite a bit of other stuff for, get this, $15! Some days you get lucky! I only use FD systems and I would recomend only an A-1, F-1 or a T-90.
