Hi Guys

I have been reading about close-up lenses vs. close-up filters and it appears that the former is a much better choice to retain quality. Is this true? I have a few questions on this topic:

- Does a close-up lens (say used on a 18-105 mm or 70-300mm) reduce the minimum focal distance?
- Also both my lenses are 67 mm - most close up lenses are only up to 58 which is unsuitable - I have heard about the Nikon 6T which is 62mm, is this good and available?
- How do I fit it to the 67mm lens?
- Is there any other alternatives?

Thanks a lot guys
