Hi Bro,

Irregardless of what focal length you are using, check your focusing distance with respect to your subject.

Cheers!

errr, Im not an expert Bro. I guess trial and error on that distance. Perhaps same theory when you are using a magnifying glass. My cents of opinion.

Hi, I also try using a closeup +4 on my canon 75-300mm lens. You can try to get closer to your subject. But it is super hard to get in focus from any thing more than 100mm even you use manual. So use it at the 70mm end. Or you can try the closeup +4 on a 50mm lens. It give good result. Hope this help...;)

I find that the 70-300mm tend to hunt under low light conditions. In any case, did you toggle the macro switch? Did you make sure that the distance between the lens and the subject is 1m? The minimum focusing distance must be obeyed too.

When you use closeup +4, your object to the lens should be less than 25cm when lens distance at infinity, regardless lens' focal length.

Closeup +4 = focal length = 1 / +4 (in meter) = 25cm.

Arto.

If I were you, I'll get the ext tubes instead. Hoya close up +3 and above produces very soft images.:thumbsd: Bad experience from 2 copies, so end up with tubes. No glass element = no degrade in IQ. Only slight loss of light. :)
