If there is no cross patent agreement, it seems like either Sony or Samsung have ripped off Canon's patent and we might have a court battle in coming days.

Those memory card pouches have been available for ages now. I remember a friend of mine got one of the CF/SD combo back in Jan. Pretty decent card wallet.

Pricing is going to key, if it comes bundled with Air1 Commander and is priced reasonably then I am considering this for macro photography. I know a lot of my friend are interested in this flash.

Zoron: Pls tell them to work on new 24-70 F2.8 AF VC.

@John : he probably means an asthetic and electronic upgrade to SP series which would mean compatibility with usb dock.

juhab: The 90mm macro's minimum focusing distance of 13.9cm/5.5in seems to be measured from the tip of the lens, not from the focal plane. http://www.tamron-usa.com/F017special/index.html says that the minimum object distance is 0.3m (11.8 in).

Is this kind of spec trickery common or did I just misunderstand something? I've just recently become macro-curious.

That 13.9cm is the working distance i.e. when you are the shortest focusing distance of the lens(30cm in case of this lens) the distace of subject from the front of the length. There is no trickery of specs going on. Working distace is a crucial(for shy bugs and dangerous animals) parameter when doing macro photography. You can easily calculate working distance of the lens from specification table. Woking distace=Minimum focusing distace-(Flange distance+Length of the lens).

Realeyes: Anyone notice how close in dimensions this new Sigma is to a Leica SL? So what? Well, this camera ticks a lot of my boxes: a decent size body - not small and puny like most mirrorless cameras; APS-H sensor - whilst not as large as FF, a nice compromise; built in EVF; good range of high performance lenses that cost less than the equivalent Canon or Nikon lenses.

The issue will be how flexible the sensor is. The Foveon sensor is not famed for its high ISO ability. But this is an auspicious product launch. Let's see what the image quality is like... And the price, of course.

+1 with your thoughts. I would have liked to see some other camera mount used as there are hardly any tilt-shift lenses for SA mount and many landsacpe shooters would love this camera for their use. Also I hope sigma has designed a large sized battery for this camera.

there were a lot of complaints about text on dials peeling off for i40, lets nissin has fixed that. other than that tiny issue, i40 was brilliant flash for macro photographers. looks like i60A might just take that crown if its priced properly. waiting for price details and availability.

It seems like those 1in sensors might be saving grace for compact camera market. Some really good compacts released in last couple of years have been using sensors of this size and now competition is heating up.

Chaitanya S: So we keep seeing more and more adopter for E mount and yet no decent native lenses for E mount. Whole argument about size advantage went down the drain that sex toy inspired G master range was announced. even bigger sting in rearside for the E mount users is the price of that range for mediocre lenses. Also advocates of small sized camera don't mind carrying around "heavy" SLR glass around.

@Rocky Mnt boy: My issue is with amount of BS Sony Fanboys give Slr users over weight when they are using adopted slr glass. This beats the purpose of small camera system when they themselves are hogging around big slr lenses as 1st lenses are mediocre or lacking selection. Look at Fuji X system they offer good selection of lenses and concentrating efforts on developing good glass for users of X system.

thanks to the leaks, that sigma 50-100mm was a known entity and has dampned the shock value of press release.

Finally a compact with proper wide angle lens built in. Eagre to see the reviews on how this new compact performs.

Dragonrider: Let's see, Samsung is quietly going out of the camera business, Canon now has on-chip A/D conversion in the 1DX II and maybe the 80D and the new Samsung phone has dual pixel AF (a Canon patent). Does anybody see a pattern here?

I suspect Canon might want to bring Samsung to court over this. That Dual Pixel implementation looks aweful lot like Canon's DPAF system. If indeed its collaboration and cross licensing then its great for Canon users as finally we will get to see sensors that are on par with Sony's sensors in terms of DR and ISO performance.

Chaitanya S: So not only Sigma inspire Canon and Tamron for build of their lenses. But tamron also copied the extremly useful lens dock feature from global vision lf lenses which means users of sigma and tamron lenses will have multiple docks and softwares to worry about.

With these docks when you micro adjust focus, the lens changes its behaviour based on those settings on any body you use. so if on Camera1 it was working perfectly before and Camera2 showed backfocus, now after adjusting those settings it may work perfectly on Camera2 while it will start front focusing on Camera1. These docks work perfectly if you are using a single body. Also Nikon on their D5 has implemented automated focus micro adjust feature which uses the contrast detect data to change phase detect focus shifts. I was shocked why didnt Canon implement that feature on their camera when they were the first to patent that technology and with their extremely accurate DPAF automated focus microadjust would have been a boon for any photographer.

NAwlins Contrarian: Wow, the 90mm macro lists for $100 CHEAPER than the current street price of the lens it replaces. Hopefully its performance will continue the good performance ofa long line of Tamron 90mm macros, of about three or four different optical formulations and about ten difference varieties.

Old lens is 599$(after 150$ rebate) so technically new lens is 50$ more also weighs a little bit more than old lens.

Nukunukoo: It's unfortunate that Sigma is now releasing more lenses without OIS. I wonder if it has something to do with Nikon's lawsuit?

that lawsuit was settled back in April. I think there are certain design choices Sigma is making for their Art series of lenses not to use OS whereas Sport and Contemprory line is getting OS.

Luis Aragon: Hoping that the second lens that is supposed to be announced will be the 85mm Art. That is the bad boy I've been waiting for.

2nd lens rumoured is a 30mm f/1.4 Dn C lens. thats a mirrorless lens. Tamron will be announcing 85mm f/1.8 VC and 90mm f/2.8 VC Macro. So maybe you should look forward to Tamrons release.
