Yes, it goes to show how the comp requirements are not always read or appreciated.

Actually there still is one showing for the May comp that was taken in April (according to the image's exif, but its date was modified to 1 May on the upload web page!.) The instructions for that comp did point out the May 2015 requirement (and that images had to be square though not all complied with that!)

The Competition Details page doesn't point out that shots have to be taken this month, just that the usual rules apply. I suppose some may get confused between the rules for the monthly/weekly comps. Perhaps it might help if there were dedicated pages with the rules for each comp that the judges could link to, or at least cut and paste what they are. JR used to trawl through and point out ineligible entries which may have drawn attention to the rules for others.

It's clever uploading picture taken in the future. I'd like to know the secret of time travel too.

Clearly release was imminent, so announcements made, but a problem was identified in the review copies. Surely it is better to get it right than to release a potential pup. Given the FF is not due until later, the delay doesn't really matter; we've enough lenses to be getting on with!

My understanding is that the 10 update can only be applied to 7 and 8.1. An upgrade from 8 will require applying the 8 to 8.1 (free) update first.

My own view is to wait and see. Certainly will not be jumping straight in to upgrade on day one! If it isn't broken can't see the point of fixing it.

Try watching a tutorial or two such as this one from Adobe themselves:

Like most things, you don't become good at them without some practice first!

Agree 100%

Surely the Tamron one is too?? If not what is it designed for?

Have you checked the entries submitted so far for the monthly? One was shot on a Sony and the other (according to the image exif) back in April despite a 1 May claim though it doesn't seem to load at all now!

Accurate focussing will be more critical on the FF body given the shallower depth of field, but I feel some need to go back to basics and use a film SLR before autofocus existed such as a Spotmatic, K or M series or equivalent. One tends to get the impression from posts here that certain photos would be impossible to obtain without cameras that have yet to be released. Clearly that isn't the case. The split prism focussing method of the older cameras seemed to make it easier to identify the point of accurate focussing and much simpler that trying to assign a zone or point on a small screen and hoping the camera's electronics will behave as intended. While one's doing that the subject's vanished!
