I am considering buying this lens and the; Meike MK-14EXT Macro TTL ring flash for Canon E-TTL; could the Raynox DCR-150 be used at the same time?

The front thread diameter for the DCR-150 is 49mm. The version of that flash ring sold on amazon seems to come with adapters for 52-77mm, so you would need a step up ring for 49mm to the size of one the supplied adapters. A 49-52mm would probably be best. Also the weight of the flash ring could be an issue because the DCR-150 is a snap on, not threaded, although mine seems sturdy.

This unit uses a single contact hot shoe trigger to turn on LED's momentarily, and is not equivalent to a strobe trip driving optical slaves. You could leave a TTL strobe on a hot shoe, or remote cable connection (or RF remote trip), and use this unit in the constant on mode, mounting its battery/control box on a separate cold shoe bracket it needed. However, hot shoe mounting of a full size TTL strobe wouldn't light the area a macro ring like this, or far more expensive strobe type, reaches directly in front of the lens. This unit doesn't do stop motion as strobes do, as it either flashes or turns on LED's (easier for focus or to use camera exposure sensors). The only reason I can see to use both at once would be to use the strobe as side fill, using a Canon TTL remote cable just as one might use with that strobe on a bracket rather than in the hot shoe.

I have a Canon Revel XS (1000D) and it worked perfectly, even in TTL. In the description of the product (NEEWER® FC-210C Wireless) You can find out if your camera is compatible with the trigger and your flash. I do not think you have problem, because the flash is fully compatible with Neewer, so it is quite possible that other works perfectly. I recommend the product 100%. A friend also bought it and it worked perfectly with his Canon camera and a flash Yongnuo.

I get excellent results with the Raynox 150, and it snaps on and off in seconds. All auto functions work perfectly. Short of an expensive tru MACRO lens, it is probably your best option.

Yes. Exactly. You can use one at the camera'a hot shoe and one other at each flash being controlled by it. Just stop looking and buy it. There's not even a closer solution available at the same price range.

I haven't tried it myself, but I don't think there would be a better combo for this purpose. I mean a 100mm macro with this specific of flash, Yongnuo or not.

The nikon version supports i-TTL/D-TTL (where metering is done through the camera system), while the canon version supports E-TTL (Evaluative through the Lens exposure) II. Copy and paste the following link for a better explanation: http://photonotes.org/articles/eos-flash/. It's probably a proprietary software difference in the exposure calculations, but from what I understand the ringlights are otherwise identical, albeit probably not interchangeable.

I seriously doubt that you will be happy with this flash. It is touted as an automatic TTL flash that works similar to name-brand flashes made for your camera. It is not. Suggest that you look seriously at the smaller Canon flash or a Metz equivalent. This flash is a manual flash and unless you are handy with setting aperture and shutter speed for different lighting situations, I would advise you to steer clear.

It should work OK as long as the the Meike flash is 100% compatible with the Nikon i-TTL/CLS system. I love the triggers in general as they fire reliably.

I don't know about that but this flash is fully manual. It will not monitor anything thru your camera and mine stopped working the 2nd time I turned it on. I would not recommend it. If you want a TTL ring flash that is fully automatic you will have to go for the Canon ring flash, about $500.

Yes, it works just fine. The folks who dinged it in reviews didn't read the product description carefully. You'll need to use manual focus, and your FD lens won't focus to infinity. On the other hand, you're not introducing another optical element of questionable quality. Use it for macro.

I use this on my 5d and 60d with the 580ex2. I have had no issue with this ring flash. The clear plastic does seem a little more flimsy than I was expecting but works without issue.

It should be compatible. It worked fine on my 50D for a short period of time. Then, I pushed too hard to get the angle correct to bounce off the ceiling for a portrait and the mount, which is made of plastic, broke. If you can be really careful, it seemed to be a decent entry-level TTL flash, but it might be worth looking for one with a metal base if you can spend a little more.

They shouldn't be interchangeable. For TTL to work properly the flashes have to be engineered for each brand. I'd send it back and get the right one. It's a bargain of a flash for the money though. You'll be happy.

As jealous as I am about your Leica....I don't think so...probably not.as it is a Nikon Product enabling you to use the Nikon TTL with off camera flash.. - I use it on a brackett for event shoots but use pocket wizards for off camera flash triggers loosing Nikon lighting smarts) I use it with a Nikon D4....My guess is your going to need to use pocket wizards and learn how to use your flash manually- there are lots of YouTube videos and tutorials on Pintrest.

I can't think of any feasible reason why that would be so. Since you're not using a dedicated TTL flash, there's only one contact being utilized on the camera hot shoe to trigger the flash.

Yes, if you know how to use it. It really does its work with the ttl flash and the tripode.
