McGrattan,
What was the distance like between the watch and camera in your first set of shots? I want something to photography relatively flat carved ivory reliefs around 3 inches tall and 3 inches wide in museum cases, where the lens might be 4 inches away from the object. Perhaps I need to go to a longer focal length.

I didn't know about the existence of this lens yet: http://www.sigmaphoto.com/shop/105mm-f28-ex-dg-os-hsm-sigma
Internal focusing, so the length remains constant. It looks like the working distance is ~18.5cm at 1:1.
By the way, if you select the lens in Sigma mount, you pay half price!
Anyway, this doesn't seem like a suitable option for a NEX -- it probably doesn't have an aperture ring even in Nikon mount.

Fly -- a standard full frame lens will offer considerably higher apparent magnification on the crop 1.5X and double on the 2X M43 sensors. So a 50 that is nominally a 1:2 on full frame will be 1:1 at the same subject distance on M43. The 90mm will behave more like a 135mm offering 1.5X magnification on Nex.
As you see, you are asking pretty much the impossible -- you'd need a very long lens like a 180mm macro to get the subject distance you want. Then you are going to run into DOF issues.
I think you'll have to throw aside your concern about small size lens if you want these magnifications. The lens will need to rack out pretty far to get to what is 1:1 on Nex sensor.
Offhand, I'd say a nice 50-60mm macro will best for inherent DOF and "okay" subject distance. You'll need to do focus stacking to get best DOF at the magnification you are asking. With focus stacking you might get best results with 90-150mm lenses.
Perhaps someone can comment from experience with the Sigma 150, or Canon 180L? Those will give best working distance.
I'm interested to see what you come up with.
BTW -- I really like the close up pictures you've been showing the last month or so.

Gunzorro - this is interesting.
Why will the apparent magnification be bigger when the sensor is getting smaller?
I thought 1:1 is 1:1 and that only the maximum size would be different which you can capture on different sensors (?)

Well, for a lens which projects a 1:1 image onto, say, a FF sensor, using that same lens on a camera with a crop factor will crop out the outer regions of that shot, apparently magnifying further.
Recall that 1:1 means that the image *on the sensor* is the same size as the object in real life. The size of the sensor doesn't change that. So while the image is still 1:1, a crop factor makes it seem larger than on a larger sensor.

In the first set of watch shots the lens was 2-3 inches from the subject.

I don't think any of these options posted so far are better than a tamron 90mm alpha mount version, the latest one. It is 1:1 and will be compatible with my a850 as well. I guess I was looking for something that was similar to the nex macro in size but slightly longer FL with a lot less CA.
I don't think I'm understanding tho. You're saying the Tamron SP 90 has too much CA too? My copies don't seem to.
Also later you called the Tamron small and light? It's not! Well maybe compared to the Zeiss MP 100 it is... but that's a behemoth!!! The one I photoed for example is about 1/2 or 1/3 the weight of the tamron and maybe something like 50mm smaller.
It does have a decent WD tho.
Several of the lenses mentioned best my copy of the Tamron SP in terms of IQ at macro focusing distances too - although not by too much.

Going to look into that Olympus 50mm F3.5.
I was saying the new version of the Tamron 90mm seems to be smaller lighter than most of the choices put forth in the same FL range. It also seems to have very little CA, decent bokeh, and decent stopped down performance. It's also compatible with my other camera which is a nice plus.

Here's a shot on my GH2 with the OM 50/3.5. I still use this lens occasionally, though I use the Leica 45/2.8 more often due to the AF, auto aperture and IS.
