Question: Do we required any filters for this lens Nikon 18-140 , If yes, can you let me know what filters required?
Document: Have used 18-200 on my D 50 Nikon since they first came out (2005?). Taken 1000's of exposures. Great all around lens. Then upgraded to D 5000, sold D 50.1000's more fine pics. Now have D7000 paired with 18-200 for most use, but wanted lighter lens to use for travel with D5000. 18-140 is perfect. IQ similar to 18-200, but much lighter. And no lens creep! And much less expensive.

The 18-140 is so far looking like a notably superior offering. Not special in an absolute sense, but the best kit lens option available today (I also have the regular 18-55 VR kit lens, which I actually think delivers comparable results to the 18-140 within their shared range - but the extra 55-140 is nice).
DXO Mark rates the 18-140 as being sharper than the 16-85 and 18-105, at least for my D7000. When you look at the DXO scores, make sure that you select the correct camera, because the 18-105 is sharper than the 18-140 on some cameras. I think the DXO sharpness ratings are valid, based on the lenses I have.The lens appears to be sharp throughout its range.
With the 18-140 range, you are covering everything from wide-angle to a decent telephoto range that will fit most photographer's needs. Unless you need a super zoom, for photographing wildlife, this is an almost perfect range, and will replace a variety of lenses, enabling you to carry only this lens for the vast majority of your photography needs. I can't overstate how important this is. For instance, on vacation, you need only bring this one lens instead of 2 or 3.
The plastic mount on my 18-105 VR broke when a friend stuffed his luggage by my camera bag. I got if fixed, and it's a good lens, but I cannot trust keeping the lens mounted on my camera. The 18-140 has a metal mount that I can trust, so it stays on the camera in my bag, ready for impromptu shots.The lens is very sharp; noticeably sharper than my 18-105 VR, which most folks think *is* sharp.
This is a great walk around lens, covering a really impressive 18-140 range (27-210 FX equv.). For the 7x zoom range, it delivers very good sharpness and decent weather protection.I liked it so much that I have decided to sell off my Sigma 18-250. While the sigma was a good compromise, the aperture at the long end (6.3) meant only the center focal point in my D7100 as accurate (f8).
This is a great lens.Firstly, it feels very solid. It's build quality is way better than the 18-55 or the 55-200 for example (this lens basically replaces both of these, and then some)... I would say it compares to the build quality of a 10-24 which I also own.The zoom ring is perfect and very smooth.It takes 67mm filters so it's a nice big piece of glass. Shooting with it - it does it's job very well.
This is the perfect travel lens for any photographer. It takes great wide shots, and the zoom to 140 works well to capture more detail. I recommend this lens to the professional and amateur.
Chances are...you are either an amateur or an enthusiast, looking to upgrade from the kit lens, and wondering which lens to buy.When I purchased my first DSLR, I spent months pouring over reviews, reading DxOMark ratings, and trying to figure out which lens would fill my needs. Every new DSLR owner always wants to know which lens they should buy, and with the selection out there, it can get overwhelming.
Answer: Many people use a  UV filter to protect the lens, but on DPReview, it appears that the filter does little to protect the lens.  So, two things:a.) Buy a lens hood; according to the anecdotes of many users on DP Review, it protects far better than a filter, and adds contrast to the image.b.) I would still buy a UV or clear filter to keep grit and dust off of the lens--who wants to disturb the multi-coatings on the lens?  And the filter will provide some protection.  Digital cameras do not need the UV portion of the filter.  I use the BW filters, because they don't attract much dust and are easier to clean.  Again, filters at least keep grit from getting on the lens (and therefore, you won't scratch a lens trying to get the grit off).
