Photography Question

Which lens for sharpness


Hi
I have a Nikon D200 with the 18 - 200 lens. I have marked that it does not give me sharp pictures that I used to get from my D70s kit. Should I opt for the 17 - 55 f2.8 lens for the sharpness that I'm looking for? Will it be suitable for wedding photography?

  Sachin, I have used the combination you have for weddings, and have not had problems with sharpness. Now this may also have to do with my using a post-processing program called DxO Optics Pro which corrects for lens abherations, but I have also heard that there has been some variation in quality of the 18-200 Nikkor, so it may be that your particular lens is probelematic.

That said, the faster 2.8 lens you mention would be a great choice for weddings, since it will give you potentialy shallower depth of field (at f2.8) that will allow you to reduce distracting backgrounds.

You can tell from its build (and price) that the 17-55 is also a "pro designed" lens; it's more rugged, with beefier components - it will last longer. That is, the aperture is less likely to break down after 25000 actuations or whatever.

I hope that helps.

  Lens are like everything else... you get what you pay for. And, like everything else, the jack of all trades is the master of none.

What you get with any 18-200 lens is a very wide focal length range. But, there's no such thing as a free lunch (T
NSTAAFL). What you give up is resolution and contrast, because there's a lot of glass in that 18-200 and it's being asked to do all sorts of weird things.

What are you looking for? Portraits and candids at weddings? Then something along the lines of a 24-70/2.8 seems like a good choice. Group photos? You might want to go a LITTLE wider, but it would be better for your subjects (more flattering) if you increased your distance instead of decreasing your focal length.

I don't know about Nikon's 17-55/2.8, but I do know about Sigma's 18-50/2.8, and it is an incredibly sharp lens. That, combined with Sigma's 50-150/2.8 would make a great combo for weddings... or for anything else. If you want to be able to go to the new Nikon D3 (full-frame), then stick with the Sigma 24-70/2.8, and get the Sigma 70-200/2.8 (another very sharp lens) as well.
