CAN I GET SOFTWARE OF OLYMPUS C-2100, 2.1M.P 49MM 10XZOOM CAMERA

The step-up ring will on any lens with a 49mm filter thread, regardless of the manufacturer. The easiest way to find out whether it works with any given lens is to see whether the ring fits onto the front of the lens (you could also read the filter size written on the lens itself).
If it doesn't fit, purchase the appropriate step-up ring. That will be much cheaper than buying a whole new set of filters.
If the new lens(es) have a 55mm filter thread then you don't need the step-up ring at all. The filters will mount directly onto the lens.

The ring threads onto the front of any lens with a 49mm filter thread, just like a filter. The front of the lens then fits onto a camera body, effectively mounting the lens "backwards" or reversed. With most lenses, this allows the lens to focus very close, for close-up or "macro" photography.

if you think that i help you plesae rate me tnx...

I am in the US, But I believe the UK based Jessops camera shops should have a 49mm lens hood to fit it. I would just get a collapsible rubber one. They are fairly cheap and just screw in the filter threads. fold them back when not in use, and you can still mount your lens cap.

You might also try Ebay. Shipping from the UK to you should be minimal, but some asian dealers offer very good bargains in those kinds of goods too.

Hey savmoney,
Your current OM lenses are not directly compatible with the current four thirds mount used on Olympus DSLR's, but there is an OM four thirds adapter which should allow you to mount your older lenses to a new Olympus DSLR. You should have limited functionality while using the adapter, but according to the manufacturer aperture priority should work and full manual. I have included a link to a chart that shows which OM lenses are supported by this adapter. I hope this helps!

Go Ahead. Use Us.

Please use thin type filters to prevent vignetting on the corners. The following filters are vignetting-free. Konica Minolta 49mm AC L37 (UV filter) (Thickness is approx. 5.5mm in total, and approx. 3.4mm excluding the screw part.) Konica Minolta 49mm ND 4x filter 49mm type causes vignetting. Please use Konica Minolta filter adapter (49mm > 62mm) and 62mm Polarizing filter II (Circular) in combination.

Get a CLA-1 lens tube. It screws into the camera body. The other end accepts 43mm accessories. Put on a 43-49mm step-up ring. Into that screw a 49mm UV filter. (The step-up ring is needed to separate the filter from the extended lens.) Leave the UV filter on at all times. Throw away the lens cap.

I had good results with my Oly 2020 and a set of Tiffen close-up lenses (+7 and +10); they are 37mm, so won't work with the 2100, but you can find something similar in 49mm and larger size.
