Bought the Raynox 250 macro adapter to use with my 18-135 lens this week, as an alternative to carrying around my macro lens.
First impressions: it's lots of fun, and not too hard to use. It also seems to let in more light than a macro lens, so you don't have to push the ISO as high
Seems like a weird statement. Why do you think that? Can you elaborate?
Okay, so let me start by saying that I could be wrong here - I'd need to do a side-by-side comparison to be sure. However:
This image was taken at f/16, 1/100s, ISO320. When I use my macro lens, I typically set the SS at around 1/80s (it's a 60mm lens), and raise the ISO to around 800 (which is about as high as I usually like to go). With those settings dialed in, I usually can't get much past f/8 before the image is unusably dark. So with all that in mind, the Raynox certainly seems brighter - presumably due to whatever difference there is between magnifying a non-macro image and focussing down to 1:1.
Like I said, maybe I'm mistaken, but this seems to be the case based on my usage today.
