EF 24-70 f/2.8L II Patent Published

EF 24-70 f/2.8L II Patent Published

It’s coming, really!
We posted the filed patent of a 24-70 f/2.8L II way back in October. However it has now been published as of April 21, 2011. The big omission appears to be IS. I think it’s safe to say the lens is coming soon.

Other Lenses in the Patent
A couple of other lenses appear in the patent. A 70-300 f/4-5.6L IS, which has been released. Also appearing is a 55-250 IS lens. This could be a version II of the current lens. It could also shrink to 200mm at the long end.

Egami notes the 24-70 patent shows possible performance issues. You can check out their findings here.


The performance does not seem to be so good. The spherical aberration is delivered to less than +-0.2mm in all conditions at the outskirts. The astigmatism exceeds 1mm extremely badly in the short distance. The distortion is -4% of barrels type in the wide side. In the short distance, the distortion is +5% of lozenge type in the tele side. The chromatic aberration of magnification is corrected well.



24-70 II in April? [CR2]

24-70 II in April? [CR2]

The end in sight?
A good source says “I’d be surprised to see the next 24-70 not announced in April”. The source does caution things could go awry because of these apparent lens delays.

The source also says the lens will be “with IS”.

I look forward to the end of the speculation on this lens.



Odds and Ends

EF 24-70 f/2.8L II
CPN magazine lists an “EF 24-70 f/2.8L II”. Typo? Probably. Here’s the picture anyway.

The lens is coming, the patent exists. Makes sense that i’ll arrive with the next full frame announcement from Canon, or shortly after. Who knows with all the Canon lens delays though.

thanks dimitri

EF 8-15 f/4L Fisheye Delayed Again?
B&H Photo is showing the lens will be arriving in May now, instead of March. Check it out.

thanks doug

EF 400 f/2.8L IS II
Delayed the same as above.

5D Mark III External Recorder?
A tipster said the prototype 5D Mark III or similar body is being tested with an external recorder capable of recording RAW video. He was unsure whether or not it was a Canon accessory or a 3rd party product.

1Ds Mark IV
I’ve received a couple of tips from underwater housing stores about the 1Ds Mark IV. It’s claimed it will be the same housing as the 1Ds Mark III.

Underwater housings have never been a good barometer for upcoming products, so I don’t even link the stores anymore. Everything I’ve been told about the 1Ds Mark IV states it will be an ergonomic change from the 1Ds3.

April Announcements?
Lots of tips saying April is the month for the next announcement. Nikon is looking to be on the same schedule. I will be very wary of April Fools Day.

I’m off to Indonesia on March 24 for a couple of weeks. I may have a fill-in for a few days while I’m away.



*UPDATE* More 5D Mark III / 1D Mark V & Lenses [CR2]

*UPDATE* No IS in a new 24-70L ?
A couple of folks have come forward and said we won’t see IS in a new 24-70L.

Remember this patent? There’s no IS.

5D Mark III
Some more clarification about the upcoming 5D Mark III. It will be moving a bit more high end with an improved 7D AF system. Expect it November/December 2011.

1D Mark V
The next version will be moving into the 1Ds territory as the new high end digital SLR. Expect it to be fullframe by the sounds of it. Late 2011/early 2012. No specs finalized yet.

24-70 f/2.8L IS
It’s coming and will be announced with a camera body at the end of 2011. I haven’t heard a peep about the lens in a while.

An interesting tale about this lens. Apparently the replacement has been canned and is being redesigned.

EF 24-70 f/2.8L Replacement [CR2]

Stop teasing me!
I know, I know. We keep talking about it and nothing happens. 99% of the stuff that comes in regarding this lens I put to the side.

However, a great source has finally spoken up in regards to a replacement. I’m not putting CR3 on it because I don’t have a specific date.

What I am told is the lens is coming “sooner rather than later”. There’s 2 possible announcement dates.

It sounds like it will be launched alone like the EF 70-200 f/2.8L IS II was. It’ll either be announced before the end of the year, OR just before WPPI which starts February 17, 2011.

It’s not confirmed it’s going to be an IS lens, though if it wasn’t. I’d be completely shocked.

This is officially the best confirmation I’ve received in regards to this lens.

You will know more the second I know more.



Cameras & Lenses From Various Sources

This and That
I have some loose information about what and when we can expect new cameras and lenses. It’s a collection from various folks.

There will be no new products that will hit the shelves before the end of 2010. There could be an announcement before 2011 however.

Another good source has suggested we will see a replacement to the 5D Mark II before a 1Ds Mark IV. It’s 50/50 with sources as to whether it’ll be a camera added to the lineup or a direct replacement of the 5D Mark II. This announcement will bring about “2-3 lenses”.

I’m beating a dead horse here, but the still expected lenses are a 24-70 upgrade, a replacement to the 180mm macro and a new prime of some kind. Lenses are always difficult to nail down far in advance.

A lot of people have said 2011 will be a big year for innovation from Canon. As we’ve seen from some of their concept products, that could very well be true.

A 7D replacement won’t hit us until 2012.

I’ve been informed to say good-bye to DIGIC IV. Expect the 60D to be the last new body with the DIGIC IV processor (outside of a replacement entry level Rebel).

As for a mirrorless camera system, I have nothing to report of any value. We’re all still shuttering from the last rumor.



G12 & SX20 Replacements & More

Announcements shortly
We can expect announcements for a few more PowerShot’s in the next 7 days.

There will be a 2nd announcement for an SLR I’m told.

1Ds Mark IV
I’ve been burned with bad information about the camera before, so I’m being very cautious as to what I publish here. I am mentioning this because it’s being sent to me from various places.

The recent flurry of emails points to a 2011 announcement date. Apparently it’s due to the lack of competition in the segement. There’s the D3x and nothing else.

It’s suggested Canon will wait until Nikon shows their cards with a D3xs or D4x.

CR’s Take
I don’t think things work this way. Canon already knows what Nikon has up their sleeves for the most part and the same the other way around. If companies held products back to see what the competition was doing, nothing would ever reach market.

Photokina is a big show, so it’s tough to see just the 60D being introduced for Photokina. Although, the need for trade shows and building product hype is lessening by the year.

Nikon will be bringing 2 more lenses to market in the next couple of weeks. I expect Canon to do at least one more.

14-24 & 24-70 are the likely candidates if I go by  recent suggestions.

This is speculation on my part.



This and That

24-70 f/2.8L IS
Lots of emails with tales of “I was told not to buy the current one”. Nothing of note beyond that.

New Rebel [CR1]
I was told there will be no 2000D. The T1i will remain current. I’m inclined to believe there will be a cheaper Rebel launched.

New 500 & 600
I was told we could expect to see these lenses hit the market as early as summer 2011.

All is pretty quiet.



1Ds Mark IV & More

1Ds Mark IV
There’s not much to talk about, I’m getting the usual variables in “tips”. Some say it’s coming before Photokina, others claim it’s 6-12 months away. Nothing definitive yet.

24-70 Update
I’m emailed daily about this lens, as I previously mentioned, I haven’t heard anything about a replacement in a long time.

New Flash
I  was told by a decent source we’ll see a new one announced before Photokina.

More cameras coming?
There is at least one announcement day coming. Outside of more Powershots, I have no CR3 info yet.

I’m told the 1D Mark IV will be getting a firmware update for Photokina. No word on features. CR1 this one.

60D Manual is Up
You can download the english user manual for the 60D. You’ll notice there is no AF microadjust in the manual.
