Macrolite Adapter 67

I bought this to fit the Canon Ring Light onto my 100mm Canon Macro lens. It is metal construction and is heavier than I thought it would be, not that it maters really, I'm just mentioning that it feels like a quality expensive product, not cheap in any way. Great purchase and if you are trying to decide whether the ring light is for you, I found it quite good at lighting jewelry in a Lightbox studio environment. Great item.

This adapter definetely worths the money. I thought a lot to go with a different option since $32 seems to be a lot for only an adaptor. But consider your ring flash get loose from your lens and you crack it, which you will end up loosing $100s.

I received the adapter promptly, but that’s where the positives end. Installation on my R6 was anything but smooth, the threading is rough and full of friction. Now, I’m unable to unscrew it. The adapter feels essentially stuck, and I’m seriously concerned for my 100mm lens, which is now trapped. Based on my experience, I strongly urge others: do not buy this product.

I use the Canon 100mm f/2.8L IS macro lens and an MT-24EX macro flash system and those two items by themselves, will not work together because the flash ring is too small to fit around the lens. It's pretty absurd that Canon hasn't fixed this, especially considering they've had half a decade to do it but that's another issue.So, you're left with one option: Buy this step-down ring and be able to attach your flash system to the lens. I personally haven't noticed much vignetting which is pretty surprising given how far out in front of the lens your flash is when using this adapter.As usual, this is just another item that should be included with the purchase of either the Canon 100mm f/2.8L IS or the MT-14EX and MT-24EX flash systems. Canon, are you listening?

This product does what it is supposed to do, and seems to do it well. I am not a professional, so I will not put my macro lens and ring light to extremely heavy usage. But the adapter fit is snug and there seems to be no danger of stripping the threads. I am very satisfied.

I have a couple of issues with this adapter. Why does it cost so much ? It is light alloy (and very little of that to boot!) It is NOT worth $40.00 or more! This is ridiculous!The macro-photography unit is expensive enough as is. I am a long time user of the Canon systems (since the days of the FTB ) and I find it odd that Canon could not come up with a more adaptable system for such an expensive accessory.

There is no room for graduated judgment on a device like this -- it either does what it is designed to do or it fails. There isn't anything in between. This adapter works.This adapter lets one of the two referenced Canon flash units attach to the front of Canon's 100 mm EF macro lens for bright illumination in close-up photography.If you are a macro photographer, you will know if you need a lens-mounted light source like Canon's macro Ring Lite. If you do, you need this adapter if you have Canon's excellent 100mm f/2.8 macro lens. If you plan to mount the ring flash or the adjustable twin flash on the dedicated MP-E 65mm macro lens, you do not need an adapter. That lens comes with the necessary mounting flange built into its basic design.

Although I am still astonished Canon did not include this adapter with the flash unit, it is a good build quality. And contrary to what it states, I am able to connect a filter to the adapter and the ringlight on the 100mm 2.8L macro lens.
