Got my Canon 500D

Arrived today.

No not that Canon 500d , but the close-up lens:



Now all I need is plenty of spare time to have a play with some close-up work with my Zuiko and Canon lens combo.

Re: Got my Canon 500D

Are these single lens optic's ?

The thing is that I got a set of close-up lenses (+1, +2, +4 and +10) from ebay recently for less than 20 pounds including shipping.

I did some testing and am impressed with the results: 1:1 with the 40-150mm with no color-fringing at all and great sharpness.
Both kitlenses seem to work good with this set and given the fact that I can use them over the entire range of the 40-150mm it gives me great working-distances.

I will be posting some pic's later this week if you want.

Greetings,
Peter

Re: Got my Canon 500D

Please forgive my total newbie question, but what are these, and when would you use them?

I've often seen them on ebay, but I'm ashamed to say, I havent a clue what they're used for

The strict definition of macro photography is 1x magnification and greater. 1x magnification would mean, for example, photographing a bee such that the image on the sensor was the same size as the bee itself.

Close-up photography tends to be used for images less than true macro magnifications.

There are many ways to get macro and close-up magnifications.

A dedicated macro lens gives best optical results but is the most expensive.

A close-up lens screws onto the front of a standard lens and acts as a simple magnifier. The cheap ones can have poor optical quality.

Extension tubes fit between the lens and camera and increase the extension and hence magnification.

Canon make a 500 which is a single lens and 250D and 500D which are double element lens so should give a better image.

Please do post some images. I haven't yet had time to try mine.
