Where can I purchase a macro accessory lens for the EX2F?

that shows the adapter barrel and filters. But I'm most interested in an added macro attachment for the camera. My last camera was a samsung sl420 and I often needed to take closer macro than the camera was capable of in order to post images of smd (surface mount devices and miniature circuit boards) to electronics forums. I discovered that a front element scavenged from a decent pair of binoculars (cheap at any goodwill) was a useful optic to hand-hold in front of the lens. Auto focus worked as usual and I was able to get very detailed and useful macro shots. Edge barreling (redundant?) was unacceptable for fine photography, but the section of board focused upon was perfectly clear.

I was excited to see that the EX2F, which I have ordered and should arrive in a week or so, sported a threaded barrel capable of accommodating an accessory macro front lens. But strangely I cannot find a single reference to it beyond the site I linked that does not ship to the U.S. Samsung "tech" chat was less than helpful. He informed me that the knurled ring on the lens was not removable. Where do they hire these guys from?

Well, I ordered this last night

52mm with threads at both ends.

I'll wait until it arrives to be sure of fit and then order the following

I'll wait till the camera comes to be sure of fit. Love that the ex2f has threads at the lens base to accept adapter barrel and 52mm filters and certain basic lenses. The quality may be reflected a bit in the price but this is not a 1200 dollar camera to begin with. The lenses are all glass and aluminum. I'm sure I'll be happy enough with the macro results since till now I was happy enough with hand holding a binocular lens in front of my older point-and-shoot.

Sorry for the double post here.   This fit better in another thread.

There are no EX2F owners here that have delved deeper into macro?

I've only got 12 dollars invested in these. I'll go five times that to enable more critical macro work with this camera. Does not need to be publishable quality, just useful macro for grabbing details well beyond the limits (admittedly good to begin with in the EX2F) of this camera.

My previous Samsung point-and-shoot had no accommodation for accessory lenses or filters, so I made use of a variety of loupes, miniature magnifying glasses, etc, temporarily held against the lens barrel or held with two sided foam tape. Experimenting with such, my 99 dollar 1/2.33 sensor Samsung camera was able to grab some astonishing, macro to microscopic detail.

I'l really like to purchase some accessory lens for the EX2F that would do good macro without such jerry-rigging.

I cannot get these Vivitar lenses to focus on subjects, no matter what mode, tweak, lighting condition, I try. It may be that the accessory threaded barrel for the EX2F is incapable of integrating 52mm macro lenses with the focus limits of the EX2F. I quickly run up against the camera's focus limits, in both auto and manual modes, with this pop-up message "this is the focus limit at the current zoom ratio".

In other Dpreview threads Panasonic LX7 owners have had success with a few other macro attachments. Raynox is mentioned. For that matter, I'm disappointed that there is so much more content in these forums from LX7 owners on this topic than EX2F owners. Is this one more indication that the EX2F appealed and sold to, finally, less enthusiastic photographers?

I'm trying so hard to love this camera.
