Indeed. My comment was really meant for you, Terry

I think the article was a kind of 'Oh I took this brilliant photos with a rubbish old camera'.
I just had a sensor clean for/on (?) my 750d today. I had acquired a blob. I
think it's going to be my camera tomorrow in France. I 'got' (i.e. bought myself!) a 6D mkII for my 50th. (The birthday was otherwise uncelebrated pretty much, so I felt I deserved the extravagence, rightly or wrongly!) I am happy with it, but I think it sometimes best to wait until a new model has been around for a bit before buying, if you are thinking of upgrading. The 6D doesn't like my Sigma lens, and still no previews in windows if you shoot in RAW. It's also damned heavy so not a great holiday camera.
I am starting a 5 week macro course at the City Lit the week after next
