just did,,, its as sharp as mup... its amazing the difference... i like the fact the screen doesnt blank out while it focus's as it does with phase detection.. ..it is slow. if the light is even slightly dim it can take 2 to 3 seconds to go green. to bad it looks like contrast detection is only a live view option. live view eats battery power like crazy.

step 1: you press the shutter once , mirror goes up out of the way so the sensor can read the image directly.

step 2 is focusing, you squeeze the shutter button 1/2 way or hit the af button and the mirror drops right back down so it can focus off the mirror like it normally does . the auto focus in live view can only work in the conventional mirror down position. at that point you are no better off then a conventionally taken photo because the mirror is starting from its normal position now as it focus's ... the disadvantge at this point is the mirror coming down has started its own set of vibrations which depending on how fast you snap your photo may compound on to the next step.

so far we had the mirror raise up so we can see the image on the screen. pushing the shutter half way or using the af button drops the mirror down (disadvange) and focus's setting up vibration from the drop.

step 3 you follow thru squeezing the shutter and the mirror slams back up same as conventionally taking a photo. this is the biggest source of vibration and it may be compounded by the dop vibrations just prior.

mup is different. mirror is raised. shutter opens after a slight delay and photo is taken. when the mirror comes down unless your hi speed shooting multiple shots the drop vibrations are gone by the next shot usually.
The Live View feature varies from camera to camera. Mine allows to shoot using the electronic first curtain. When you press the shutter, the camera resets the sensor to begin the exposure, and then closes the shutter curtain at the end. The mirror does not make a difference. While I can use auto-focus, I prefer manual focus for close-ups.

me too, i only use manual focus for macro... in fact i only use manual camera mode for my macro

are you using nikon? all the above is only based on the way nikon does it when you have live view. i believe all the cameras with live view have the same handheld and tripod mode.

I use Canon, but the Live View mode of some Canon cameras is similar to the Live View of some Nikon cameras. There are four or five types of Live View systems being used by camera manufacturers. Live View has been improved quite a lot on recent months.

And you are correct on the way Live View works with your camera.

hi hoping someone can help me out or give me some insight/advice!!

i will be purchasing the d7000 and have the option of the following lenses:
AF-S DX NIKKOR 18-105mm f/3.5-5.6G ED VR
AF-S DX NIKKOR 55-300mm f/4.5-5.6G ED VR
and
AF-S DX VR Zoom-NIKKOR 55-200mm f/4-5.6G IF-ED

i dont know about the image quality of any of these lenses.

i should add that the 18-105mm will cost $300, the 55-300 will cost me $249 and the 55-200 i can get for free through some cc rewards program.

the problem is that i dont have an 18-55mm lens to compliment the other zoom lenses. the 18-105 offers a lot of versatility in that i dont need to walk around with 2 lenses but again its the most expensive option. i was thinking about getting the free lens (55-200) and selling it, and maybe getting an 18-55 or similar lens with that money.

Any suggestions? any advice or help would be greatly appreciated. thank you

IMO ... I'd get the 55-200mm for free, sell it on E-Bay/Craigslist/here for $150 and buy the 55-300mm for $100 plus the $150 you got for the other lens. And then Buy an 18-55mm kit lens on the cheap or even used from B&H, KEH, Adorama or Amazon. Just my .02 cents worth. I haven't really heard any good or bad about the 18-105mm lens to form an opinion

I had 55-200 and 70-300. Both VR. Was not too impressed with either. Was not sharp from corner to corner and gets worse at 200 or 300 end. Sold both and got 70-200 f2.8. Beautiful glass.

I have the 18-200 VR lens and actualy love it as a travel lens. Its the only one I bring with me, and while it isnt great at anything, its very good at pretty much everything. Its a nice all purpose lens

I too would recommend skipping these kit lenses and get a travel zoom. I can't speak for Nikon 18-200 VR but I find Sigma 18-250 HSM OS offering good quality on my Sony A55 (Sigma OS = Nikon VR). It is a versatile lens, somewhat heavy compared to kit lenses (but compensates for it by eliminating the need to carry more than one lens). It isn't any slower than these kit lenses either.

And then shop for some fast Nikon prime lenses depending on your budget.
