Regarding Watboy's comment on auto focus I would make the following observations. If you are using the 60mm macro and shooting very close, say 1:3 or closer to 1:1 a lot of the AF speed has to do with your technique. I think both the EM-1 and EM-5 focus quite fast with most lenses. The big difference between the two cameras is the large improvement in C-AF with the E-M1 and the PDAF for use with the excellent line of four thirds lenses from the Olympus DSLR systems.
If you are not shooting 4/3 lenses or using continuous AF then speed differences between the two cameras is limited. You also have a faster burst rate and a larger buffer with the E-M1 about 60 RAW images at 6.5 frames per second in AF. These features are directed more towards the Pro or advanced enthusiast rather than the shooter using S-AF.
I would also agree that the image quality of the E-M5 is very good and that you would want to be looking for more than just the moderate improvement in image quality of the E-M1 if you are going to make the move up to the E-M1.
I think that if you are buying a new nauticam system new, the EM1 is worth every penny over the EM5.
While I agree with your math this is not really apples to apples. The EM-1 is at the beginning of its cycle which should for the Pro camera last about three years. The run for the EM-5 is coming to an end about two years and the new OM-D EM-10 to be announced in the next few months will be a step down from EM-5. So if you want to wait over a year for the EM-1 I am sure it will drop 20% like the EM-5 has on sale and the difference will again be about $400.00. If cost is your main issue then I think the EM-5 is hard to beat with any camera of the same image quality.
