Impressed by its finish, fits perfectly. My only tiny disappointment is that I found the lens alignment dot been colored dull red, was difficult to see...I have remarked with a spot of white paint...problem solved.

Stuck T ring
Wednesday, 19 August 2020  | 

I dont know if it's my lack of knowledge or not but I inserted the T ring into my EOS Canon T6 and now I cant remove it, it is way to tight


Check you have depressed the release button on your camera to enable this to be removed. Also take care when fitting - if anything feels tight with this or any adapter, don't force it!

Perfect fit

Bought for canon M50 and fits perfectly with no movement. Note that the fitting shows a red dot not the usual white for canon M fitting but it still fits Eos M cameras.

A solid T ring
Monday, 3 February 2020  | 

A very solid feeling T ring, however, the inner ring came loose inside my T adapter on first use without me noticing and had me really confused when I tried to use it again. I had to buy a set of Allen keys to get it fixed back in place but after tightening it, it's going nowhere.

Perfect for the job
Thursday, 4 April 2019  | 

Arrived quickly, as is always the case when ordering from FLO. Product is well made and looks/feels like you could drop it from a 50 story building and it would just shrug it off. Connects perfectly to my Canon 700D on the camera end and also connects directly to my Skywatcher 200p's 2"- 1.25" eyepiece converter once the 1.25" tube is unscrewed. I can also connect it to the 1.25" nose piece of my eyepiece projection unit which allows me to screw regular filters into the image train without needing to buy larger filters or even clip in filters. Buying a more expensive Canon t-ring will get you absolutely nothing extra over this fine offering, if you need a Canon t-ring, just stop looking and buy this one, you'll be more than happy.

t ring didn't fit
Saturday, 16 March 2019  | 

t ring didn't fit on my micro 4/3 camera.i checked with FLO that it was meant to twist on all the way. i returned the item (at my expence) and received a refund.i then bought one from someone else (different make) and it fitted fine.
since FLO don't use micro 4/3, as they said , they couldn't test it, but it may possibly have been a 4/3 one. As far as i am concerned they sent me the wrong item ,and seemed a bit grudging to consider this a possibility.
they made me feel i was in the wrong. maybe they don't need the business ,but having ordered previously and it all been fine, i am sad that i'll never use FLO again.I don't mind paying to send it back but what i wanted was a follow up .I must assume since they didn't offer to send another, they did find that it was the wrong one, else why not offer me a replacement?


We are sorry to hear you were dissapointed with your experience, Robin. Unfortunately because it happened around four months ago it is difficult for us to fully recall what happened. Looking at the email communications it appears there was some misunderstanding about the problem and how you wanted us to resolve it. We did not find a fault with the adapter nor did we experience faults with any other adapters from the same batch so we can only conclude it was perhaps a little tighter than you would have liked for your camera.
We regret you did not provide this feedback when the problem occured because it is rare that things go wrong and rarer still that we are unable to provide a positive solution. We hope over time you will reconsider your opinion of FLO.
