Default C-750 Lens Adapter?

I recently purchased the c-750. I realize that in order to add wide angle or other lenses to it I would need to use a conversion lens adapter. But if I simply want to add a UV filter to protect the "naked" lens, do I need an adapter or is there some way to directly mount one without the extra item?

You need an adapter tube. The camera end is 45.6mm, and you cane get 52mm or 55mm on the other end. If you have another camera(SLR) that uses one or the other of these sizes, make the decision with sharing filters in mind. If not, the 52MM may be a bit cheaper on average. I got my tube and filters from:
http://www.2filters.com./ . Good prices and fast service.

You need a filter adapter tube...this is a tube that screws into the body at the base of the lens, and goes from 45.6mm to one of the following sizes:

55mm (Olympus CLA-4)
52mm, 46mm, 37mm (from third parties, the last two sizes though have more chance of vignetting...note that you can use the exact same tubes as the C-700/720/730).

You can find the 3rd party tubes at http://www.2filter.com/prices/products/digitubes.html

The photo of the shadow caused by the CL-4 tube at wide angle makes me think that it might not be a good idea to always use the tube/UV lens for protection.

What's the general consensus, guys, do you always keep a filter on as a lens protector, or just on some occasions? I know I always had a uv lens on my 35mm as a protector, and I sure don't want to scratch the lens on an expensive digital camera, but I also don't want to ruin my shots with lens tube shadows.

Also, it's a shame that Olympus doesn't make the CLA-4 in brushed chrome so that it would look better with the camera.

Robs, the adapter tube I got from 2filters.com is brushed aluminum with a 3/8" band of polished area. Looks nice with the C-7XX series. If you think there will be a problem with shadow on wide angle, you can unscrew it easily enough.

As far as lens protection goes, I usually keep the tube installed, although the lens is recessed and probably a bit more secure than on a typical SLR.

Default C-750, lens protection

Robs,

if it is only about protection, I highly recommend the OLYCAP. I have been using it from the beginning with my C-4000Z. It kept my lens totally protected and spotless clean. It also is so affordable, you can't do wrong.

Cope,
Is there a particular model # for the tube you bought? The one on the Yahoo site does look more integrated than the black unit Olympus sells.

BOW45652T @$11.93. If I remember correctly, their shipping charge was around $3-3.50. They ship USPS, and I got mine in a couple of days. I had a senior moment and forgot to order a lens cap for the 52MM filter, so I had to place another order.

The shadow is caused when using the internal flash...even without the tube on this can happen when shooting macro or at wider angles.

Regarding keeping the tube on the camera, I keep it on the camera with a Skylight filter AT ALL TIMES, except when I want to use the external flash (like when I was at a school reunion where I didn't want to risk the flash shadow showing up).

As for the OLYCAP at http://www.olympuscap.homestead.com/ it is a great lenscap for the camera but offers none of the protection a tube and filter can provide...both the glass of the lens and the lens barrel itself are exposed to the same possible mishaps they are exposed to without the OLYCAP on the camera. Once the camera is turned on, the OLYCAP is useless at providing protection while the filter tube and filter encase the lens barrel and protect it from impact damage, and the lens from being touched.

Not to change the subject, but which is the preferred "lens protector", the UV filter or the skylight?
