Sadly, it looks like Kodak is continuing to push Super 8 to extinction.
Between their previous and now more recent price increases on Super 8 film and the drastically reduced costs of very good transfer to HD or even 2K, there seems to be little cost advantage left for using Super 8 vs 16mm.
At $24/roll (and that's wholesale prices, so I'm sure it will be more retail) plus $20 processing (I'm rounding up to counter the wholesale vs retail film cost) we are talking nearly $45/roll for film and process. Give an average HD transfer for $20 per roll and we are up to $65 per roll.
Now say $42/roll for 16mm and $20 more to process. That's $62/roll for film and process of 16mm. Then, a decent transfer of that 100ft roll is about $25. So, your 16mm cost is $87 vs $65 for Super 8.
So, between the superior image of 16mm and in most cases far superior (and prolific) scanning options for 16mm, other than the "Super 8 look".... why shoot Super 8 anymore? And of course, in my opinion, the "Super 8 look" died with E100D and Velvia50D.
