Tokina EF Lens Compatibility with EOS R6 Mark II

stcapp1426 — Wed, 25 Oct 2023 13:55:07 GMT

I am planning to buy this camera but would like to know if it's compatible with the Tokina atx-i 100mm f/2.8 FF Macro Lens for Canon EF that I already own. I know some non-Canon EF lenses won't work with the new mirrorless cameras. Does anyone know about this particular lens? Overall, I like the lens - it suits my hobbyist needs. Thank you!

It would at least require an EF to RF mount adapter (do only purchase Canon's adapters), but that's no guarantee that the lens will fully work.

It would be far better to eventually move to an RF 100mm f/2.8 L Macro.

Yes I knew I'd have to buy the converter and will need that anyway for another Canon EF lens, but was hoping not to have to buy the macro lens right now! But I also knew that might be there case. Thank you for your reply.

If you plan to use other Canon EF lenses, then just buy the Canon mount adapter and try it.

Yes that's definitely my plan. No need to replace it until I find it doesn't work! Thanks for your reply.

Sherri,

I can't specifically answer your question but I can say of all the lenses that may have problems, the Tokina line up is probably top of the list. I have tested dozens upon dozens of lenses and found Tokina to be the most problematic as a group. This does not mean it won't work but the only way to know for sure is to try it. If it is your only EF mount lens I personally would not buy the adapter just to be able to use that lens. As Ricky, above, pointed out, "It would be far better to ... move to an RF 100mm f/2.8 L Macro." The adapter is around $150 bucks. Money that could be put towards the RF Canon version of the 100mm macro. It is a far better totally compatible with your new camera lens.

There are a couple gems in the Tokina lens line up but not many. In my experience, unless Tokina has changed in the past few years CS is nonexistent if you ever need it.

I bought it initially because it was not very expensive and I didn't know whether I was going to like macro photography. After having it for a year and a half, I realize I do enjoy it. I do have a 23 - 105 EF lens so I will need to buy the adapter anyway. What I don't understand is why the RF macro is 1:1.4 instead of 1:1 like its EF counterpart. Or am I reading something wrong in the specs?

I bought it because I didn't want to spend a lot and it had good reviews. I figured it was good enough for someone who had never done macro before. I will try it, since I have to buy the adapter anyway and if it doesn't work, I'll get the Canon lens. Thanks for your reply.

The EF 100mm f2.8L Macro was the close-up lens everyone wanted. It still could be a valid choice for you. Wonderful lens with excellent results both near and far. But the RF 100mm f2.8L Macro out-performs it in a number of ways. Most obviously it delivers the greater reproduction without the use of accessories: 1.4x versus 1x on the older EF model.

Nope, that is correct. We of course, don't know why Canon did that, but it might be due to the SA or that fact that the focus distance is already 10" at 1:1.4.

Thank you! I'm still trying to understand magnification, but someone I know here who is heavily into macro told me that I want 1x. I don't know why and what the difference in the final image would be. If the Tokina doesn't work or work well, I will buy the RF - and it's cheaper!

As a hobbiest, I still have a lot to learn, and magnification is one of them!

Just optics and a little mechanics.

Since any lens has an "angle of view" - which is a function of focal length and sensor size. If you imagine a cone stretching out from the lens, it is pretty easy to calculate the magnification at any point along the axis of the cone.

The trick is, higher magnifications are closer to the lens, so you have to be able to focus close to the lens to get high magnifications. This is what macro lenses do.

Thank you. Still trying to wrap my head around it!

"... someone I know here who is heavily into macro told me that I want 1x."

That can be true but it is not an end all statement. 1 to 1 is generally consider to be macro. However the ad boys in the lens department tend to throw the word "macro" around with some abandon. A lot of lenses that are called "macro" can not do 1 to 1. So technically they are not true macro lenses. Beside the fact true macro lenses are designed differently than GP lenses.

All advice is not necessarily good advice. You must weigh it carefully when applying it to your specific requirements.

You have that backwards. The RF 100mm f/2.8L IS USM macro has 1.4x magnification, 1.4:1. And as of this posting, it's on sale at the Canon U.S.A. store, and probably other authorized Canon dealers. I have had it for quite a while and it is quite good. I also have the EF version.

From the Canon website.

Everything from a technical perspective was covered previously. 👍

Adding to Newton's post above.

Canon RF 100mm, (today) new $999

Canon Refurb (today) $899

Shop Canon Refurbished RF100mm F2.8 L MACRO IS USM | Canon U.S.A., Inc

I did the above a few months ago ($799). Above is still a great deal. Black Friday is coming, but things can sell out fast as the holidays approach. I've learned over the years that holding out for another $50-$100 that may or may not happen is not worth missing a deal. Refurb items can go in and out of stock quickly. I hope the Tokina works out, but if not this is a great time of year to treat yourself.

LOL! I paid full price two and a half years ago, and I had the EF version. Just couldn't wait, heh heh 😉

OK I thought it was the reverse but again, I'm not experienced in this area.
