Were these new designs or lenses from the 80's/90's still produced?I seem to recall the Vivitar MF lines to have been around as late as 2004 or so...
You're not going to find many, if any, third party lens for the Canon FD mount though. It was a complicated mount, and Canon killed it early on.
No because VR and IS technology uses AF technology as well. They use the AF sensors to detect motion somehow. You however can have IBIS using these lenses.Did the third party lens manufacturers ever have IS or VR-like feature in mounts like the Canon FD? Tangentially related: when did they discontinue lenses for these mounts? I seem to recall the Vivitar MF lines to have been around as late as 2004 or so...
My impression too. I got no problem finding locally 3rd party FD-mount lenses, much ,much more common than Canon-made ones.I've always been under the impression it's one of the most common mounts ever made for SLR's.
dSLRs use VR and IS, and the AF sensor is NOT used to detect motion...that detection is entirely within the lens, via gyroscopes.No because VR and IS technology uses AF technology as well. They use the AF sensors to detect motion somehow. You however can have IBIS using these lenses.
yes, which is why the thought even entered my mind to begin with, considering that MF lenses for these older mounts continued production for some time after the end of vendor supportdSLRs use VR and IS, and the AF sensor is NOT used to detect motion...that detection is entirely within the lens, via gyroscopes.

Not insurmountable, but there would have to be a control button on the lens to activate the stabilitzation system, and a battery in the lens to power the stabilization system!yes, which is why the thought even entered my mind to begin with, considering that MF lenses for these older mounts continued production for some time after the end of vendor support
Exactly. That is why I considered already years ago to remount such lens for FD mount. But as so far none of such lenses showed up in the rummage boxes I frequent...Not insurmountable, but there would have to be a control button on the lens to activate the stabilitzation system, and a battery in the lens to power the stabilization system!
you say that, and i come across this (old stock as all Adaptall-2 lenses were discontinued 2006): https://www.bhphotovideo.com/c/prod..._A17200_28_200mm_f_3_8_5_6_LD_Aspherical.htmlHard to say when MF went out of production, there was a lot of old stock in the pipeline.

yup, but it’s worth noting that the in-lens image stabilization requires power in the lens. Some of the older mounts such as FD may never have had that connection designed in (I don’t know in the case of FD because I know little of Canon 35mm.). Certainly, there was never a mechanism for power transfer with M42 lenses. Was there on Minolta or Olympus? Nikon and Pentax K having carried their mount from the manual focus universe all the way to present have added power features to the mount (even though Pentax use the power for AF motors, but not in lens image stabilization AFAIK.)

This site would help with Tamron lens historyI referred to Adaptall above, but I am really surprised to learn that the range was offered that long. Have you an idea when the last model was added to the Adaptall range?
I thought the lens I referred to had been the last.
I know this site. But it is incomplete. For instance the lens I mentioned is not even listed.
