New analysis of Nikon E series production numbers, should be a bit more accurate

Post by Ross_Alford » Tue Jun 09, 2020 10:20 am

I went through today and consolidated all the E series serial numbers that have been posted through April 2020. I posted a anew list that is presently at the end of the serial number thread http://nikonweb.com/forum/viewtopic.php ... 3747#p3747

I did it so I could update the analysis I did back in 2006 of E series production numbers. http://nikonweb.com/forum/viewtopic.php?f=3&t=710

See the link for exactly how it was done. I redid it, using the new list, which has 159 numbers instead of 123, a fair bit more data. This time I used both the Bayesian and frequentist techniques (see the Wikipedia article i referenced in the original post) for each year's run of each model, when they both worked (the Bayesian doesn't work when there is only one camera in a year), and took whichever estimate was larger, and added them up for each model. The results were very similar to last time, and with the increased data, the total is actually a bit smaller, and should be a bit more accurate.

Model Production
E2 321
E2N 671
E2Ns 125
E2S 198
E3 449
E3S 220
DS-505 206
DS-505A 225
DS-515 98
DS-515A 30
DS-560 322
DS-565 114

Total 2979

Last time the total estimate was 3058, very similar. Having more samples means this should be a better estimate. They still are really quite small numbers.

Of course, immediately after I redid the analysis and posted the new one, someone on a Facebook camera group gave me a new serial number, E2N 7300125

Adding that makes the table

Model Production
E2 321
E2N 687
E2Ns 125
E2S 198
E3 449
E3S 220
DS-505 206
DS-505A 225
DS-515 98
DS-515A 30
DS-560 322
DS-565 114

Total 2995
