Input: Consider Input: Lens seems fine. I was actually impressed when I first took it out. Color looked great. Smooth aperture and focus rings. Then I realized I can't focus any further than about 8 ft. Others have said this is an issue with the adapter, which is probably the case. However I am able to focus very closely. I wonder if that's because of the adapter as well. Either way I think I'll keep it since it's just 25 bucks and try other adapters

Output: 3

Input: Consider Input: It is not as good as the official replacement: a little soft, takes a little more time to clean the teeth. But can be used. It is cheaper if you would not mind to clean teeth a little longer.

Output: 3

Input: Consider Input: Not sure why people give such a high rating. The book lacks planning advise and sample itineraries, just wordy descriptions about all sites. How am I supposed to know how long each place takes to visit given a relatively tight schedule? Not good for first-time visitors.
