For all those wondering what had changed: https://www.lensrentals.com/blog/2018/08/lens-teardowns-and-comparisons-of-the-canon-70-200mm-f2-8-is-ii-and-iii/ [EDIT: In case you can't be bothered to read the whole article, I'll summarise it for you: the paint colour has changed and according to...

I thought I’d mention this as I haven’t seen it on another thread (apologies if I’ve missed it!), but DPReview have a review of the new Tamron 70-210 f/4 that compares it against the new Canon EF 70-200 f/4L IS II with zoomable images at various apertures...

Found on Egami via Photorumors: http://photorumors.com/2016/03/13/the-latest-patents-from-sony-and-canon/ Appears to relate to using full frame lenses with sensor based IS to allow greater stabilisation on APS-C bodies. They're probably thinking of movie shooters shooting handheld in place of...

Everyone is raving about the BSI sensor on the A7r ii; whilst it is yet another visible step forwards in Sony sensor technology, I don't think that the much vaulted BSI is really such a game changer. It's been said by others before, but the fill factor advantage isn't nearly as important on full...

I feel a little guilty, I've started to cheat. It's not like there's anything wrong with her, she's still as beautiful as ever, it's just that I've started to notice things about her that hadn't bothered me before. You see, how do you put this politely, she's a bit heavy and indiscrete...

Apologies for my lack of posts over the past few months, I've been living overseas and only have a tablet with me -the touch sceen interface is very frustrating for use on the CR Forum. This leads me onto my next request: I am looking for a laptop, on which I can edit my photos. For the past...

Roger Cicala does another short comparison ;) http://www.lensrentals.com/blog

http://www.photozone.de/canon-eos/874-canon_1018_4556is This has actually been online for two days, but doesn't seem to have its own thread yet (unless I've missed it, in which case please accept my apologies), despite having been mentioned in at least one thread already. It looks like a...

He's done some multiple sample tests against the Zeiss Otus and Canon 50mm f/1.2L, though he isn't confident enough in his sample size to give too many definitive conclusions (he only tested seven ;) )! http://www.lensrentals.com/blog

Bryan has posted his review of the Sigma 50mm f/1.4 "Art" http://www.the-digital-picture.com/Reviews/Sigma-50mm-f-1.4-DG-HSM-Art-Lens.aspx The verdict: "With excellent image quality and great design, this lens becomes the easy 50mm AF lens choice. AF consistency remains this lens' biggest...

I have a friend whose 24-70 f/2.8 L II is currently with Canon, as the front coating appears to be separating from the glass of the front element. Has anyone else experienced anything like this with any of their lenses and if so, how did Canon respond?

Pretty similar to the Canon 24-105 L, but with better centre resolution... EDIT: Sorry, forgot to post the link -how rude of me! http://www.photozone.de/canon_eos_ff/864-sigma24105f4eos

Take that Canon and Nikon, Sony are about to revolutionize our lives with this! http://www.bbc.co.uk/news/technology-25099262 And to think that people made fun of that Canon calculator mouse!

I’ve owned the 5D Mk III for about nine moths, so I'm using it as an example, but these issues apply to a greater or lesser degree to all the mid-range bodies. I am aware the others have made most of these points before, but I still wish to add my (albeit humble) voice to their cause. [list...
