Manfrotto 088LBP Adapter

I just bought a Ball Head for my tripod and it didn't fit my camera.  So, I bought this.  Now, everything fits perfectly.  Would recommend this one if you need an adapter.

I got this unit as part of a monopod kit that I purchased a few years ago. It is pretty well built but the functionality is pretty basic. I have not been using it for sometime because it was a pain screwing it in and taking it off the camera. I wish I had a 234RC instead because of the Quick Release plate.

Well what do you know, Manfrotto has a Quick Release Adapter (323RC2) that you can mount on top of it (See pictures I uploaded). I have been using it more recently because I can switch the camera quickly from the tripod (488RC2 mounted) to the monopod (234 + 323RC2 mounted) since both uses the same base plate.

If you are in the market for a "basic tilt head", I would suggest getting the 234RC. If you already have this item and want to upgrade it, get the 323RC2 adapter.

Very happy with this adapter,  It fits and works as needed.  The price was excellent since other sites as well as Radio Shack cost over $20.

On my Manfrotto 486RC2 won't quite lock-in on the head so I've stopped using it.  My research implied it was compatible but doesn't seem to be.

The Induro 484-001 tilthead is nicely built at a good price. What I missed though was that while it has a 1/4" male screw to attach to the camera it has a 3/8" female to attach to the monopod. I bought a cheaper non-Induro monopod and then had to buy a 3/8" to 1/4" adapter to make it work. I bought two: a Bogen - Manfrotto 1/4-20 To 3/8" Adapter w/Flange thinking the flange would make it better. I would jam tighter on the monopod than on the tilt head, which meant it stayed on the monopod and I could not put the camera monopod alone. I went with a simple adapter such as the Gitzo GS5000 3/8-Inch to 1/4-20-Inch Reducer Adapter and it stays in the tilthead as needed.

Went to go use my GoPro on a tripod and was confused as to why there wasn't any way to attach it as I assumed that all cameras were universal in having that little screw connection on the bottom of the camera. Since it didn't have it on the camera or as an attachment, I did a quick search and found this item. It's use is pretty simple and merges the standard tripod connection with the swiveling prong used for the GoPro.

I gave this product 4 stars because I think that this product is slightly over priced especially since the same adapter is often included in other bundles for free (an option I would've gone with if I hadn't already bought one). Other than that though, the piece is solid plastic with the metal screw connection for the tripod and seems like it will stay put even if it took a knock.

I purchased this L bracket for my Nikon 800, not expecting much given the price; however, it fits perfectly. I had a screw problem like the other reviewer, except that the screw that did come with mine was too long.  Easy fix and not worth a star.  I usually set the bracket about 3/4" out from the body to accommodate access to the ports on the left side of the camera, again, it works fine in this configuration.  One of my concerns was the fit precision for my tripod.  I have one L-bracket where the Arca Wedge is too narrow.  Not this one, it fits snug and works with my tripod head.  Obviously the brackets from the two big names out there are going to be heftier and more durable, but I can buy 6-8 of these at the price of the top of the line products.  as an avid shooter, I'd rather save my savings on this for better lenses!

It is well built but it won't fit the MeFOTO tripod/monopod that I have and I have not been able to find an adapter to use it.

With a standard PL 259 male connector on the end. If you are attaching anything that would put sideways loading on it I recommend using a shim or washer that just allows the adapter to bottom out. The quality of the machine work and material is high and its gold plated. But the screw threads aren't designed for high torque or sideways loading. Attach the adapter first just snug, then the cable or antenna. At UHF and above connecters and cable tend to get lossy so keep it snug and use short or thick cable like RG 213 or RG 8 and < 12 feet for RG 58 & 18 feet for thicker cable.

There are enough reviews here to let people know you need this AND some sort of adapter for your camera to make this work.

The adapter itself is pretty well made. It is a simple metal ring. It has the correct threading on the inside of the ring and the outside. This is not some cheap plastic thing that will snap between your fingers. The price tag seems a bit high for a little metal ring. But it is a very specialized piece of equipment, your almost certainly not going to be using this for anything else.

Pros:
  *Well constructed, not flimsy feeling
  *Made out of metal, not cheap plastic
  *Does what is made to do

Cons:
  *Expensive for such a small item

Received the adapter yesterday.  It is well made.  Goes on the camera body well.  OM lens attached well.  I like it.
Only problem is that many of my OM lenses are too heavy for my plastic body e-500.  I think the old lenses are metal or aluminum.
I'll stick to wide angle and 50 mm primes.  For zooms, I may need to get an old e-1 or e-300 to better deal with the weight of the OM lenses.

Awesome cold shoe mount with umbrella adapter. I just wish Manfrotto would supply the mandatory Manfrotto 119 Female Spigot for 026 1/4-Inch 20 Female and 3/8-Inch Female 31mm Long Adapter with this.

This adaptor working great for Manfrotto tripod with ball head and supporting larger lens with Samsung NX 300.
Price is right.

One of the wonders of the "GoPro" age is that the old standard of tripod mounting threaded inserts are not supplied with the action cams offered today. Most of them therefore need an adapter which this does nicely. Also nice is that it adapts the standard "GoPro" screw mount so once you have it on the tripod you can maneuver the camera into your desired position. A nice inexpensive little gadget to add to your action cam gear.

The adapter does what it's supposed to do.  It fits perfectly.  Boo on Nikon for requiring such an expensive adapter rather than putting a connector on the camera to begin with.
