Macro filter
Thank you AggieDad, I did consider the Raynox but a couple of reviews said the mount wasn't always that positive a connection so it would have been nice to have tried one in a shop instead of relying on the Internet. This arrangement at least gives me the option to use a ring flash; the down side i...

BTW: please try to refrain from referring to a close-up "lens" as a macro "filter" because it's not a "filter"!

BTW: please try to refrain from referring to a close-up "lens" as a macro "filter" because it's not a "filter"! Unfortunately calling it a lens gives the potential for confusion with a dedicated macro lens such as the DA100 Macro... IMO 'filter' whilst inaccurate is easily understood. I try to re...

BTW: please try to refrain from referring to a close-up "lens" as a macro "filter" because it's not a "filter"! I know it's not a filter but to keep referring to it as "the magnifying glass that fits onto a lens" is a bit of a pain and doesn't Google so well!

Close Up Lens would be the usual designation, usually available in dioptres up to +10. Some are doublets, and I think the Raynox is. That is, two elements cemented together to reduce aberrations.

Marumi call it a close-up lens filter, which they produce in four versions; +3, achromats in +3 & +5, and a +10. The achromats have 'multiple lenses', as John says to reduce aberrations. Not the cheapest and prices vary with thread size but first impressions are good. If you are interested: http://w...

There's an excellent web page on using the Raynox . It gives you a lot of information, including how to stack them and a nice calculator to give you magnification and working distance with different lenses.

I use the Raynox 250 when I don't want to carry a macro lens around. I have found it to be an excellent alternative and have had no problem with the connector. I was very impressed whith how it performed on the 50-135mm ... almost made me sell my macro lens. by , on Flickr

Thanks for the feedback, and your generous offer Jon, but I have just spent about £55 on the Marumi so am unwilling to switch now! The examples are great, and dare I say that the quality of both the Raynox and Marumi are able to give outstanding results from such a modest piece of kit. I only came a...

Step up and step down rings
I have a 67mm haida nd3.0 filter which has a 67mm thread. It came with a 67 to 62mm ring which i use on my 18-135 lens. I have a sigma 10-20mm lens which has a 77mm thread. Could i use a couple of rings (77 to 72 and 72 to 67) to make a 67mm filter fit a 77mm lens? Would the lower diameter filter a...

Or should i be looking to get a 77mm filter, and use step down rings to fit all my lower diameter lenses. I'm afraid so... !! First rule always buy filters the size of your largest lens.. Then step down..

what causes this?
i was experimenting with some long exposures using an nd3.0 filter, and every image has this light steak on the bottom third of the image. Only the long exposures, between 15 and 30 seconds, have this, all normal exposure images are fine. Ive never really tried this before, am i doing doing somethin...

what causes this?
I agree with George - for long exposures with a ND filter, you will need to cover the viewfinder. When I did this without covering the viewfinder, I didn't get the streak effect - but got the washed out look across the frame

Recommend a Lightweight Tripod
i always use a tripod at least once on holiday when using my 10 stop filter so would not travel without it. i have a "3 legged thing" punks version but i see now they appear to be only doing carbon fibre and no mag alloy ones so they have become very pricey compared to what they were. the other i h...

Winter holiday in Northern Norway
There are several excellent tutorials online for photographing the aurora. You will need a good tripod, a remote (or use the 3second delay), preferably shoot RAW, with a wide angle lens, no filters on the lens, manual lens or not set the camera to manual focus and pre-focus at infinity. Set the ...
