Does this work with the EF 75-300 F-Stop: 4-5.6

I don't see why it wouldn't, I have it on my 55-250 and it says it is for it in the description.

According to what I can find, it does. I do not personally have the ef 75-300 f/ 4-5.6 so I do not have personal experience with the lens.

I purchased this adapter so I could use my Tamron SP 55B 500mm mirror lens on my Canon EOS. It works fine. It also works for the Tamron 2x SP tele-converter. I would assume that it would work for any Tamron SP series lens. (Note, the SP series lenses were for 35mm film SLRs). I think the 75-300 lens is not in the SP series, so it might not work with this adapter.

If you are not familiar with Ed Mika, he engineers and makes customized adapters for old Canon lenses and is the only on-line vendor that I would trust with FD-EF converters. However, Ed Mika's website currently does not show an adapter for the FL 50 1.4.

I don't own that lense but can tel you that from my experience with another canon EF lense 70 - 200mm f/4l it works including AF.This dubler will not work with any EFS lense from Canon due to protruding internal dust ring which comes past the connector ring in all EFS Lenses. I own Sigma 18-250mm f/3.5-6.3 HSM lense which does connect to this doubler but doubler is missing profile for that lense so it can only be used in manual focus mode. Overall it is a very nice doubler especially for the price and size (canon doubler is almost twice the length of this one). Andy

I've used it on my T3i, and I don't think canon would have changed their ef mount standards, so yes it should work. I have not tried it with EF-S lenses but the telltale white dot is on there.

The min and Max f stop are listed in the description.. F3.5 to F5.6... But it also depends on your focal length or iso... It can be up to f22 at 55mm

The "EF 75-300mm f/4.0-5.6 III" isn't designed to use a lens collar at all, it has no location to fit any collar around it, and it isn't heavy enough to need one either. I have the "70-300mm F/4.0-5.6L IS USM" and that one is a heavy beast and is clearly designed for a collar, and benefits from using one. I do have the Photodiox collar for that lens and can say they do make great products for the price, assuming they claim compatibility for your lens.

yes, using it with the T5i - but should work with any EF(-S) mount from what I can tell.quality acceptable but not perfect. maybe for some extra bucks you can get smtg that wrosk all the time - these tend to loose contact sometimes, you have to screw/unscrew occasionally. I am an amateur and don't use this often, so it's ok for me.

NO NO NO! this is a M42 (thread Screw) to EF adapter. You need the FD to EF adapter. Good luck!

I believe it's compatible, but I think the F.stops vary 1 to 2 stops meaning you'll need to compensate your focus and lighting. hope that helps. it's an awesome lens. I use it with my D5100, I too need to compensate.

It will only work in Manual mode only. all other modes require the connection to the lens to change f-stop and ISO.

No, they use a physically different mounting. There are Teleconverters on the used market that fit FD lenses, do a search on Amazon and ebay for one. If you are hoping to make a FD lens work with a EF mount, there are good converters from Ed Micka, but they are hand made and expensive. The commonly available ones degrade the image. Canon made a FD-EOS converter, they are scarce and price is out of this world.

The EF 12 and EF 25 are mainly used for close up macro work. The EF 25 will get your lens closer to the object. Most people that do a lot of macro work have both. This gives you 12 25 and 37 if mounted together. It's your choice. I understand there are kits that contain two or more tubes, but I have no experience with them.

Yup, it will work on any EF or EF-S mount. Obviously, you will have to adjust the aperture and focus accordingly. Also, adapting older lenses to digital sensors often results in chromatic aberration, so make sure to look out for that (its generally fairly easy to correct in post however).

It should, it is a EOS system and they all use the EF mount. This item: Opteka 500mm f/8 High Definition Preset Telephoto Lens for Canon EOS 1D, 5D, 6D, 7D, 10D, 20D, 30D, ... $89.95 should work fine because it provides the correct EF adapter.See this article...http://en.wikipedia.org/wiki/Canon_EOS

"the sensor is designed to work with Canon's EF and EF-S lenses with a conversion factor of 1.6x"... Short answer, yes.
