Tigger, you threw me a curve ball. I think you meant to say aperture when you say focal length? I fully understand the mm conversion but rarely is there a mention of aperture equivalency.
Hi Londonfire, sorry, youare correct, I did intend to say aperture. Again, you are correct, rarely do folks discuss the effect of crop factor on the "equivalent" aperature of a lens FF versus DX. I am not a fan boy of Tony Northrup but I admit in this particular context his discussion about how crop factor effects equivalent lens comparisons was IMHO a good discussion and explained the relationship very well in non technical language.

I shot the 18-200 for years. It was a great lens.

I totally agree. The 28 to 300 is the perfect one for general photography.
I concur

Keep in mind, this is for equivalent depth of field, not exposure.

Marty, 18-200 x 1.5 = the 27-300 focal length.
Yep under stand the maths. I have a 70 to 200 @ F2.8 FX, where I apply this formula of 1.5, So I still apply it on a DX lens as well? On a D 300s crop sensor. Thanks for the quick reply.

ANY lens.
Doesn't matter if it's for DX, FX, medium or large format.

Got that, the reason I'am asking is when I mount 18 to 200 DX on d800 fx it gives me a red box and shoots in cropped sensor mode. So what's math calculation formula is used with this lens? Going backwards. At the moment i'am falling out with myself! About the conversion chartš¤

Neither creep. Your decision based on what you shoot.

Disagree when walking around with my camera strapped to my neck and it's not lock off it creeps out. Or is my lens in fault then?

Seems many copies of teh 18-200 version I did creep when pointed in a vertical plane. So to fix this issue, Nikon added the locking device to the lens in the Version II. Again, some copies of the Version II do not seem to creep, but other copies do, mine does! For what it may/or not be worth, I sent my 18-200 back to Nikon asking if the "creeping issue could be adjusted or preferably fixed. Nikon returned the lens and said that they had inspected the lens and I quote ...."the lens has been inspected and found to be within specifications"....
Determination: you like me have a "creepy" lens. However, mine does work as it has when it was new (now 5 years old) and I did get a free cleaning of the lens as it had accumulated some sand/dirt or whatever particles during a safari.

I have a few zooms with a lock switch and I use it when stowing the lenses away but overall really wonder how important it is? Is there anyone out there that uses this switch between shots? In other words, you take a couple waterfall shots and then lock the lens to walk to your next opportunity and unlock it again? I would find that a real pain in the butt.

Your are bang on the money! That's what I was trying to explain it's on when you want it off and off when you need it on. It's only good whilest walking from shoots to shoots

Frustrating, I know. I do not use a camera strap around my neck or a camera hand grip. so I lock the lens when it goes into my camera bag and leave it locked until I decide to take a photograph. When walking, my camera is hanging from my chest (lens pointing down) on a Cotton Carrier, so the lens lock is on. I have become quite adept at switching the lens lock off as I swing the camera out of the Cotton Carrier holder and raise the camera to my eye. Over the past 5 years that I have had the 18-200 it has become an automatic habit to switchthe lens lock on/off as needed so I do not find it a troublesome issue any more but did at first. Did a recent check of all the photos I have taken since aquiring this lens in July of 2011 to find I use this lens more than any of my other lenses, approximately 50% of the time I take a photo it is with this lens.

I am going to discipline my self from today I also like the 18 to 200 on my D 200 in fact it's always on that body . I now use a spider belt, it is just what the doctor ordered it is a must have when you carry two camers

Will this be your only lens? Or do you already have some lenses?
Pretty hard to recommend, without knowing what else you already have in your kit.
