Hello Erica, There are a bunch of threads already on this subject, you can always search for a topic (macro lens) and read through them. I have the Canon 100mm f/2.8 macro lens with a Pro-Master ringflash (the store didn't have the Canon MR-14EX). The lens is a 1:1 lens with focusing distance at about 1 foot away. They also just came out with an L lens with IS for shooters that use their macro lens for other type of shooting. I see no reason to upgrade to that lens as mine is sharp and I always use a tripod & manually focus - so I am not shooting fast paced like at weddings, etc.. There are a couple of courses here at BP for macro photography. There is a bit of a learning curve but once you have a few basics down, you can create some great macro images. I have thought about selling mine as I want to get the Canon 180mm L macro lens. Cheers... 3/20/2010 8:11:42 PM |

I was out playing with a Zeiss Luminar lens, basically a microscope lens mounted on my camera. I am a little closer than 1:1 with the set-up I used. There are a lot of fun things you can do with microscopes. Here is an article on the subject: www.siskinphoto.com/magazine/zpdf/Microscope.pdf. There are a lot of very creative ways to do micro work that don’t rely on proprietary lenses. Thanks... 3/21/2010 8:54:29 PM |

The Sigma 105mm is very nice as is the Sigma 180mm ... and Carlton has already mentioned the Canon 100mm lens. All these are great lenses and John has a creative idea too!

Another option is to extend the rear element with a set of extension tubes or a bellows assembly. Depending upon the lens focal length and amount of extension, extreme magnifications are possible with no glass elements to compromise the integrity of the lens.

Question Aperant dust on senser. Right from new, I have what apears to be dust on the sensor, my luck , but the diferance is that between F2.8 and f9, it is not visable, F11 to f22 , very visable, other cameras its either there or its not.I have cleaned my lenses, I have blown the senser , nothing moves it , given that its only at those f stops, is it realy dust? It is on a D300 Nikon, vibrating senser does nothing, nor huricane blower, nor vaccum, and its definatly in camera. 4/6/2010 11:31:38 AM |

Hi Steve, I don’t know, but this sounds like something on the lens, perhaps on the back. If it was on the sensor the aperture shouldn’t affect it. Good luck! John Siskin 4/6/2010 3:12:24 PM |

Hay John, Thanks for the input, sorry for being in the wrong place also, Computer iliterate I am . I have cleaned front and back of the lenses, also changing lenses does nothing , so it has to be in camera , definatly a diferant situation it is,i was hoping some one may have heard of such a delema?.I can fix the pictures , but I am getting tired of the extra steps . Thanks for the response . Steve. 4/6/2010 3:56:49 PM |
