No I wasn't - else I would have quoted your comment
Fair enough. You'll forgive me for thinking so given that you commented immediately after me and I hadn't noticed anyone else had made a statement similar to what you put in quotations marks.
I wouldn't accept that the 7D is 'far superior for sports action photography' over the 5DII. It has the edge on AF and fps - but not that much - as it then loses out on iso. From experience it is in wildlife where the 7D pulls away more.
Interesting view and actually I appreciate that from someone who has used the 5D2 and 7D as extensively as you have. I've used the 5D2 a few times (borrowed) but only just recently bought one since the prices are now so low and I'm glad to know it will be more useful for sports photography than I thought it would be. I don't think the general consensus (going by what I've heard and read on this site and elsewhere) is that the 7D only has a small edge on the 5D2 for AF and fps. It also has an edge over the 5D2 on weather sealing which is certainly beneficial for outdoor sports.
I feel that reading something into Flickr stats would apply only to Flickr users. Not that many serious or pro togs using Flickr - they have their own websites.
True, stats can be misleading if applied to populations that are not well represented by the sample population. If there are few pro photographers posting to Flickr as you say then any insights can not be applied to pros. Several of the comments about the Flickr data questioned the applicability and from a statistics perspective I think that there could be a bias in the "type of user".
I just copied the Flickr usage stats for Canon into Excel and added it up for fun (fun?) to see what it looks like for all camera types. The "avg. daily users" is a one day snapshot so the numbers I have a different from what 7enderbender got and the "one day" thing is itself a limitation. Data from yesterday is a total of 47,370 members posted a photo with a Canon camera. Of those 34,218 (72%) were from a DSLR. Of those 8,617 (25%) were from a 5D, 5D2, or 7D and 25,601 (75%) were from any other Canon DSLR.
I agree it's not something we can draw big conclusions from but it's interesting.
