What is meant by 2.8mm optional lense?

The company apparently ships the product sometimes with a 2.8 mm lens (extremely wide angle), but you'll get 3.6 lens if you order this. I see you can buy the IPC-HDB3200C/2.8 version, which would ship with the 2.8 mm lens.

This kit is all 1.25 inch eye pieces, I think the XT8 and up have a 2" Crayford focuser, but comes standard with an adapter to 1.25". So as long as you have the adapter you can use these. 2" lenses are far more expensive and I cannot personally attest to their worth, but I have heard they are nice if you have a focuser to accept them.

You need to match the filter size to each individual lens. You need a 52mm filter for the 1.8, and a 72mm for the 18-200.

It depends of the use of the lenses, the 2.8 is much better and for small quantities of pictures you can handle the lenses, but for a continuos use the best option for this lenses is a monopod.

Sorry, but I do not really understand your question. This lens can be attached to the lens without any adapter (as a filter).

8X optical zoom in lens is built in. There is no means to attach additional lenses

This lens is great for low light. The F/2.8 aperture is fast and there is little need for a tripod.

It's the lens, a 2.8mm will give you the widest possible view, 12 being the closest.

Since the introduction of the E-PL2, the kit 14-42mm lenses are all of the "II" variety. For the OMD, it's the 2.

It's the only lens I use for my 800. With occasional hiccups trying to focus through car window glass. It's sharp enough for my varied uses. I was sold on the lens by tests performed and published on the blog Photography Life and you'll also find info on the 24-70, but the 2.8 will give you a softer background.

Absolutely nothing. I carry a D600 with a 200mm lense with no problem. Rarely do I believe the 'hype on gadgets', but this is the real deal. One of the best purchases I have made for outdoors photography!

Hi John! If you are doing landscape photography, you don't really need a F2.8 lens. In my opinion, you would want to be between f11-f16 & even f22 for landscape. You will have to use a tripod at night regardless at such small apertures. Having a f2.8 lens won't help you take a sharp picture at night. What you need a good tripod for night photography because of the long exposure :)

No lenses do this.An f2.8 lens when racked out from infinity to 1:1 magnification is by definition working at f5.6.The number is the ratio of the distance from the sensor to the aperture divided by the diameter of the aperture.At infinity the aperture is basically 105mm from the sensor (simple lens approximation).At 1:1 the aperture is basically 210mm from the sensor.So the aperture is roughly halved.http://en.wikipedia.org/wiki/F-number#Working_f-number

2.8 will provide a wider view, reference the link for a relative example. http://learnphotographywithtomgrill.blogspot.com/2011/05/lenses-introduction-to-focal-lengths.html

The 2.8 gives you slightly better VR and one more stop over the f4. You could always take advantage of Amazon's 30 day return policy and try the f4. If it works well for you, keep it. If not, return it for the f2.8 model. Your current lens has NO VR, so either lens would be a big improvement.
