Sorry for the triple post but it's in my own thread anyways, so no biggie. After researching both lenses, I think that the 90mm will be the better choice for what I want to do. Mostly macro and close ups of insects, flowers, misc small animals. I have other better faster lenses for portrait work and that looks like it would be the only advantage to the 60mm. I do not think the f2.0 is going to be a major selling point because for macro I doubt I'd ever have it set that low. I'm afraid that with the 60 I'd be too close to some of the subjects and would probably prefer the slightly longer working distance of the 90mm


edit, Still undecided

I am now reading that even though the 60mm obviously would need to be held closer at a full 1:1 magnification, I can not find any concrete specs for working distance on the 90mm. I am wondering if the actual working distance will be that different.

11.4" is your minimal working distance for the 90/2.8 tamron

11.4" is the minimum focus distance, but working distance is different. It is the difference between the end of the lens and the subject when the lens is capturing a true 1:1 image. The 60mm has a minimum focal length of 9.1" but a working distance of 100mm (4")
Minimum focus distance is a measurement from the cameras image sensor to the subject. Working distance is the measurement of the end of the lens to the subject. Working distance usually increases with focal length, meaning that when capturing a true 1:1 reproduction I should be able to hold the 90mm further from my subject then I would have to hold the 60mm.

What I have read though indicates that the actual lens of the 90mm is recessed about 4cm into the body of the lens. That will reduce the distance I can hold the camera away from my subject, but I cannot find any definite working distance specs for this lens in the first place.

I think I have made up my mind. The 90mm will give me most of what I want and still retain autofocus in my d40x. The next step up that I would consider a viable option is a new sigma 150mm and that is just a bit out of my price range. I will be ordering this lens tomorrow and hopefully posting results (photos) by the end of the week!
