Since moving from canon to nikon, I only have a 55mm f2.8 micro nikkor to use. Works brilliantly well, but the distance from the end of the lens to the subject is tiny. Since I have a mamiya 645 extension tube and several lenses, I've dodged having to buy another macro for now as I can use the 150mm f2.8 with the tube to get closer than the normal 1.5m limit. (~55-60cm I reckon) The larger image circle means that the quality loss in the corners is cropped out. (similar to an FX lens on a DX camera but the crop factor is larger) I also have a 2x TC for it too which doubles the effective magnification, though the drop in quality even with the huge image circle is quite noticeable.
Here are a few taken with the 150 f2.8 A.

Like the first one. Smooth bokeh.
What would be the total magnification of the 150mm with the TC?

Thanks. Bokeh is lovely on the 150 but not so great on the 80. I'm going to give the 210 a go at some point today and see how that fairs. Using an online calculator, it seems that magnification using just the no.3 tube (35.4mm) is 1:2.8. I've measured MFD at ~75-80cm and it calculated at 0.768. I'm not sure whether adding the TC makes this 1:1.4 or not as extension tubes seem to have an odd effect on magnification based on the calculator results.

Don't rely on online calculators.
The easiest method is to shoot a ruler in mm with the same rig that you're going to shoot with.
Then divide your sensor width to what you see on the ruler.
If you have a 36mm sensor and what you see on the ruler is 9mm then the magnification is X4.

Gave the 150 some more exercise this afternoon. Very pleased with how well the combination works.

Some more samples from this lovely lens. It's replaced my macro, 135 and 180mm lenses as I love the way this lens renders.
