Patent: Sigma 200mm f/2 DG OS USM & 1.4 Teleconverter

[Canon Rumors Guy]

It looks like Sigma is developing a competitor to one of my favourite Canon lenses, the EF 200mm f/2L IS. This is one of those lenses that once you try one, you never want to put it down. It’s a very versatile focal length and is especially magical for portrait work.</p>

I like the way Sigma is always presenting something new and interesting.
Of course this is just a patent and we'll see if it's becoming a product,
but if so it will be quite interesting seeing this comparing to the Canon offer in price, AF and IQ.

 

[Chaitanya]

Doesnt Sigma already offer 1.4x TC under their Sport line up?

 

[Monchomac]

So...Sigma Art lenses are anywhere from 30% to 50% cheaper than the canon "L" equivalents so it could be from 2,800 to 4,000 ? Unless they really want to take canon down and, they could go for about $2,000. Even I would save for one!

Very interesting. If this becomes a reality, though, Sigma absolutely HAS to get the focus consistency gremlins dealt with. This is an incredibly demanding focal length.

 

[pierlux]

I wonder whether the "dedicated 1.4X teleconverter" will work with Canon lenses, too, and, in particular, with those lenses - I'm thinking of the 70-300 L - which do not accept teleconverters other than the Kenko.

 

[Cali Capture]

Isn't the Canon 200mm f/2 version ll, on the CR list of possible 2016 announcements? it still has the old 2mode IS and is starting to look a bit dated. A sigma would keep canon's price down. Hoping the Olympics will give us a new 200 f/2! Only rented this one, but sure is great for indoor sports, and improved IS would make it better, so long as they don't blow up the cost!

And in other news, Sigma's CEO also stated that he was deliberately withholding the 85mm f/1.4 Art from the public with no plans to release it:

"It's done, it's phenomenal, and you'll never have one! I will release other focal lengths of Sigma Art lenses just to flummox you! Moohahaha!!"

[Etienne]

At first reading I thought the teleconverter was built-in. Too bad. Still looks like a really interesting lens if it's relatively affordable.

 

[scyrene]

Very interesting. I'd love a 200L f/2 but the price is so high - even secondhand - I just can't justify it (in the meantime I hope to get a 200 1.8, even with all the drawbacks - lack of IS, so-so ergonomics, focus by wire lack of repair support). A third party equivalent would be a good compromise - assuming it was reasonably good.

It's official, Sigma has now attained the status level of "Overlord of the Lens Industry".

"New and interesting", as in the same as Canon's lens, Alrighty then.

the new and interesting part is that you won't have to spend 6 grand to get a 200mm f/2

That was my first thought. Unless Sigma corrects their auto focus and copy variation issues, I would avoid this lens even if it was incredible optically. Out of focus pictures are out of focus pictures...

I got mine for $5.5k - the best money ever spent.

 

[Jopa]

Oh no... The old 2 mode IS kills it!!! The new 3 mode IS adds so much to the optical quality, it makes the images taken with the poor old 200 look like cr@p LOL

 

[Maiaibing]

For the right price ~2.500$ I'd accept some OOF shots and take 2 each time I needed one.

 

[wsmith96]

This is very interesting news. Like everyone else, I'll be keeping my eye on this one with hopes of accurate focusing.

 

[addola]

The Sigma 120-300 f/2.8 DG OS sells for $3,399 so I expect a 200mm f/2 to sell around that price if not more!
