I thank the author of this article for writing it. I recently saw, and purchased a Minolta bellows set, along with a MD-MA adapter ring, and included a Vivitar 200mm f/3.5 lens. Need to stand back four [bad word filtered] ' feet from the subject, but it does work.
![]() I'm going to be looking to replace the 200mm with a 35 or 50mm Minolta MD lens. Also, I'm looking at getting a set of tube rings, since I can't get my KM 7D to attach to the bellows. There's a spot on the camera that interferes and gets in the way. I think if I put one ring in there, I should be able to move the camera back far enough to get it on. My A58 doesn't have any problems getting on, though. But, I don't have the ADP-MAA flash adapter yet, so I can't program my 3600HS for off camera use with the A58. I think this will be fun, although I was told I've opened a Pandora's box. We'll see. ![]() Gary |

Optimal is to mount a reversed lens on an extension tube.
As example. If you want a 5X magnification you set the focus so that it would give 1/5 magnification, and mount it so the distance from lens to sensor is the same as it would be from lens to subject if normally mounted. The working distance used like this is always going to be the normal distance from back of lens to sensor. Something around 3cm? This way the lens is always operating as designed. Sort of. It is going to give maximum IQ possible for the lens. Used this way the minimum magnification becomes the 1/x where x was was the lens's maximum magnification used normally. Reversing is best for when you want greater than 1X magnification. If you don't start with some sort of macro lens then perhaps a lot greater. A 50mm macro might be a good starting point. |

THe 50mm reversed direct onto the camera should give about 1:1, a 28mm gives about 2:1 the 18-70 kit lens at 18mm gives about 4.5:1, but at only a few mm working distance

50mm is more common for studio and flower shots.
Something around 100mm is normally regarded as the most versatile macro lens. So it's probably the best starting point. If you like macro photography, you can branch out from there (i.e. get something shorter, get something longer etc). If you are not intended to use the macro primarily as a macro, then there are other nice 50mm options. Both the older Minolta 50/1.4 and the more recent Sony 50/1.4 could be worth a look. |

Thanks! The other thing is I have a minolta 50mm 1.7 which I don't like because I have a hard time shooting around the chromatic abberation and it's not a terribly sharp lens either so replacing it with the Sony macro would give me a respectable 2.8 and much sharper. But what you're telling me about the advantages of 100mm (or 135 I suppose) make a 100mm macro sound much more appealing and versatile for the macro aspect. |

50mm is considered a more 'normal' field of view, but the disadvantage is that working distance gets very small, i.e. for a given level of magnification, you'll need to be a lot closer to your subject with a 50mm lens than with 100mm. That can mean it's hard to light your subject, and if it's a live subject, you may end up scaring it off. I'd say only consider 50mm macro if you want to take studio shots of static subjects. |

Very interesting topic and which has gotten my little gears spinning and thinking about macro photography. So I went to a camera store yesterday and I saw a used Sony 50mm macro lens for 300 euros.
My question is: are there any advantages to a 50mm macro lens over a 100mm macro lens other than smaller size and lower price? (Though I'm not sure the 300 euros is such a good deal even though it was in perfect condition.) |

Here's a sample shot with a Minolta MD Rokkor 50mm/1.4 reversed on a beercan, handheld (A100, ISO 400, 1/100s at f/4, zoom FL at 75mm). The subject is the decorative pattern on the end of a stainless steel butter knife -- it's high reflectivity helped keep the shutter speed up, a darker subject would've been harder to shoot under these conditions). Converted from RAW, no sharpening or PP, just a resize.
The little flower is about 5mm in diameter. ![]() There was a little camera shake, I think (remember this was handheld), but it is only noticeable at 100%. Still, it looks like you could get a good, sharp image with the use of a tripod, or in better light. Two 100% crops follow. Notice how narrow the DOF is (see second crop especially). ![]() ![]() |

Hi Ken!
Great to see you here! Thanks, the 50mm is treated as it deserves, like a gem. It was invaluable at my youngest daughter's birthday party as I didn't have to mess things up with a flash. To be honest, I'm probably not using it as much as I could as I haven't explored all the possibilities yet, but I love it! It is not the lens I'm hand-holding reversed for macro, though, I'd hate to expose it like that. I have an MD 50mm that I picked up for a song for that. Thanks, chthoniid and albnok for your replies, it helps to know how these things work. I haven't started thinking about reversing a lens on another yet, I'd have to learn a bit more before trying that, how to couple them together for a start. Half the time I feel I'm running before I can walk anyway, so sometimes I need to put the brakes on. I think I probably need to invest in a real macro lens... |

Topazlizz, albnok is correct, I just tried a 135 MD reversed on my bellows setup which I have not yet been successful with yet and the distance with the 135 is a few feet where the others are where you are on top of the subject. A guy I have on my flickr contacts list is unreal with his stuff, he actually has a photo of his setup one or two pages in:
