Hello. I have a couple of objectives I would like to use with my Canon EOS T6.
Couldn't find anything on Google and in this forum.
I need specs for adapters, since I can not get them from abroad (I'm in Brazil).

- Vivitar 75-300 mm, 1:4.5-5.6, MC, Macro Focusing Zoom and
- Vivitar 28 mm, 1:2.8, MC, Wide Angle.

The other is some threaded (like lens over) Soligor Super Wide and I can't get a precise diameter measurement with my Vernier Caliper.
I think it is around 52-53 mm and both a step-up (49-52 or 53) and step-down (58-52 or 53) ring would suffice...
What is its real diameter ?
I would love if someone could help me with this. Even if it is not of any value to use those old-timers lenses and add-on.
Thanks a lot,

Anhanga Brasil.

Here's a link to a recent discussion of a similar question. You'd be better served shopping for EOS compatible lenses assuming the Vivitar are even FD-mounts.

You’ll need to know what mount those lenses are to select the correct adapter. If you can you post some pictures of them, including your vernier readings, someone should be able to advise. Good luck!

Thanks. Will read it.

Vivitar made lenses for many difference systems. We'd have to know what's already on the lens to say for sure what adapter is needed.

Vivitar also made interchangeable mount lenses... several different types (T-mounts are the most common).

Same with Soligor, though from your description, it might be an M42 screwmount lens (used by early Pentax and several other manufacturers).

No, a plain "step ring" won't work. For the lens to be able to focus properly, any adapter or interchangeable mount must position it very precisely... so that the lens flange to film/sensor plane is exactly correct. In the case of Canon EOS/EF camera like yours, that "lens register" is 44mm.

Take photos of the rear of the lens and any marking around it that might give a clue what mount is already on it or if it's an interchangeable type, post the photos here and we might be able to help you. Otherwise, we'd just be guessing. Above info just isn't sufficient.

There also are photos of various lens mounts online.

Here's a website that has a lot of general info about using manual focus and adapted lenses on EOS/EF cameras like yours:

(Won't help you identify the specific mount of your lenses, though.)

OK. I got some pics of the mounts and other stuff.
I was hard to take those using one hand only (I was
trying to improve the lighting with the other).
Let's see if I can attach them all...
Thanks for any help.

The Vivitars are Nikon Ais (Nikon F) mount. In the links I gave, select your EOS mount, then Nikon lens, and take your pick.
Edit: You don’t need an adapter for cine or G lenses - either the plain Vello or FotodioX Pro will do. My personal pick would be the latter. $20 more, but it’s stainless coated brass vs. zinc alloy.

Thanks a lot. As a matter of fact, those are used on a Nikon FM2. As for the Soligor Super Wide, I can't see much I could use it for... But some simple step-up/down rings would allow me to fit it over my Canon lenses (50 and 18-55). They are really cheap here and I can order a couple... nothing to lose. ;)

Great. Have fun, that’s what it’s all about!

It is an F mount Nikon. Get an F mount adapter on E Bay with the glass in it so you can focus to infinity.

Yes... those are Nikon F-mount.

But, no... you don't need an adapter with glass in it for those.

They are easily adapted without need for "correction". Nikon F lens register is something like 46.5mm.... EOS/EF's is 44mm. That leaves plenty of room for an adapter without any added optics.

You might want to consider a "chipped" adapter. Those allow your camera's Focus Confirmation to work and that can be really helpful using older manual focus lenses.

Chipped adapters are a little more expensive, but worth it IMO. They are easily identified by the electronic contacts that look like the ones on the back of your Canon lens(es).

Some of those chips are "programmable"... you can set them to identify the focal length of the lens, for example. However it's usually more trouble than it's worth to do. It really doesn't add any other functionality... just records some info in image EXIF.

Using those lenses on your camera can be done either with fully manual exposure (using the camera's built in meter). Or, you can use Av... Aperture Priority auto exposure mode where you set the ISO and select the aperture using the control ring on the lens, then the camera will set a shutter speeds for an accurate exposure.

You CANNOT use Tv (Shutter Priority) or Program auto exposure modes. You also cannot use any of the "super auto" modes like "A+" or "Sports/Running Man", "Scenery/Mountain", etc.

I don't know if your camera has Auto ISO, but it might be possible to use that with Manual. I have never tried it, but it seems like it should work okay with adapted lenses.

As mentioned, you'll need to set the aperture using the ring around the lens marked with f-stops. The "electronic" method of setting it using a dial on your camera won't work, because there are no electronics in those lenses.

As you manually stop the lens down, your viewfinder will grow dimmer because when the lens is used via an adapter, "wide open" aperture isn't maintained, the way it is with your Canon lenses on the camera (they stop down momentarily at the very instant of exposure, then open the aperture back up to make composing and focusing easier. Trying to focus an adapted, manual focus lens stopped down to f/11 or smaller can be difficult using the modern DSLRs optical viewfinder. You might want to try using Live View instead. Not sure if your camera offers it in Live View, but check the manual to see if it can do "Exposure Simulation", which can be used to brighten up the image on the screen to help make manual focusing easier. On most Canon DSLRs you also can "zoom in" Live View to a higher magnification to check focus accuracy.

One other thing... Nikon lenses mount turning the opposite direction from Canon... So when you are installing the adapter, be sure to turn it the correct direction. (Once the adapter is installed, to attach to your camera it will turn the same direction as your Canon lenses.)

Is the "Soligor Super Wide" an auxiliary lens designed to mount to the front of another lens? If so, it wouldn't have any aperture or f-stop adjustments of its own. The other lens would provide that and the auxiliary lens is simply sort of a "corrective" lens fitted to the front of it... Some of those auxiliary lenses are high quality... but a lot of them aren't. It might be fun to try it on your 18-55mm, which is already "mildly wide". It attaches just like a filter... and step rings might be used if the threads on the auxiliary lens don't match up with those on the lens you're trying to attach it to. I think all the Canon 18-55mm use 58mm filters. Your 50mm, which is more of a short telephoto on your camera, might use 49mm, 52mm, 58mm or 72mm filters, depending upon which 50mm you've got. Those would tell you what size one side of the step ring needs to be. You'll need to figure out what the other side needs to be, to match up with the auxiliary lens.

Wow ! Excellent and comprehensive input. Thanks.
I am aware of most of the tips, such as direction of rotation on lens' mounts, reduction of luminosity (sp ? Luminance ?) while setting the aperture, etcoetera et al.
The adapter with chip could be a problem, but I think I prefer to rely on my eyes alone. If it goes bad, I will do it again...
after all, that's not film... just pixels. ;) and I shoot in RAW + JPG.

The only one thing that I have yet on auto is "White Balance". I have a 18% gray card (Nikon) and it will be quite boring to use it for variable environments.

Finally, the Soligor is indeed what you described, besides being heavy. I agree that it could be interesting to try it over the 18-55.

Thanks, again, for your most valuable reply. Be Well,

Anhanga.

Oh... I forgot about ISO. I try to keep it at 100 for the most outdoor situations. And yes, the T6 has the option for Auto ISO, but I an very patient on what concerns to taking photos. Last walk I had I took 36 in almost 2 hours, counting the ones I missed at the first shot.

Sorry for a "Chapter II" on a reply... My bad... :(
