EOS Bodies / Re: This web site is making me question why I lurk here

Great read, thanks for sharing.

I am conscience of the issues you're speaking of, and were trying to figure out a solution to change the dynamics of some of the conversations.

I always appreciate people that "report" posts, we do read those and usually agree and take the appropriate action. Anyone can do it.


Thanks

EOS Bodies / Canon Invite April 16, 2012 at NAB
« on: March 29, 2012, 08:47:50 AM »
Technical Invite
Canon has sent out another invite for April 16, 2012. This will be beyond the screening from the other invite.

Could this be the hoped for 4K DSLR Canon has already teased the world with? As some would say, is this what videographers wanted the 5D Mark III to be?

We have heard the 4K DSLR would be announced sooner than later, however it’s rumoured availability would be in the distant future.

*UPDATE* Canon’s Official Response
Canon USA has issued an official response to the 5D III IS noise issue:

“We have acknowledged that when using the camera with specific lenses, there is an abnormal noise during IS operation when the shutter button is pressed halfway (or remains pressed halfway), and we are now considering the countermeasures. We will let you know about the countermeasures as soon as they are finalized”

The two affected lenses are the Canon EF 200mm f/2.0 L IS USM Lens and the Canon EF 800mm f/5.6 L IS USM Lens.

Note that image quality is not affected by the abnormality. Also note that this noise does not occur during Live View including during video capture.

The Bugs No camera these days is going to launch issue free, and a very noticeable one has shown up with the 5D Mark III is used in combination with the EF 200 f/2L IS. The issue being an odd and rather loud noise from the what seems to be the image stabilizer. I have noticed this first hand while using the combination in AI Servo mode.

Others have noticed it, and there’s a thread on the FredMiranda forums about it.

I have tested multiple 5D Mark III bodies with the following lenses. I also tested multiple 1D Mark IVs with them as well.

  • 300 f/2.8L IS
  • 300 f/2.8L IS II
  • 400 f/2.8L IS
  • 400 f/2.8L IS II
  • 400 f/4 DO IS
  • 500 f/4L IS
  • 600 f/4L IS
  • 800 f/5.6L IS (this came out the same time as the 200 f/2L IS)

Conclusion I could only obviously reproduce the issue with the EF 200 f/2L IS on the 5D Mark III bodies, there was zero issue with the 1D Mark IV.  I have two EF 800 f/5.6L IS lenses, and initially I didn’t notice the noise, but it is slightly there once I took the lenses out of the office. It sounds a bit louder on the 5D Mark III than on the 1D Mark IV although the 200mm is definitely louder. I could be hearing things on the 800.

I have noticed images aren’t quite as sharp with the EF 200 f/2L IS on the 5D Mark III, I imagine it has something to do with the IS issues in AI Servo mode.

Lenses / Canon EF 200-400 f/4L IS 1.4x Finally Ready? [CR2]
« on: March 28, 2012, 09:43:26 PM »
Official announcement soon.
I’m told we’re going to see an official announcement for the Canon EF 200-400 f/4L IS 1.4x lens soon. I’m told once production (availability in May) of the EF 500 f/4L IS II & EF 600 f/4L IS II are going strong, the new zoom will be officially announced.  Expect stock to arrive fairly quickly after the announcement.

Expected retail price is around $11,000 USD.

EF 24-70 f/2.8L II I’m still hearing a release date of April 17, 2012 for the new version of a classic. Everything I have been told about this lens has been unbelievably positive. I’ve heard “best zoom Canon has ever made”, “fastest focusing” & “unbelievably sharp” on numerous occasions.

Preorder the Canon EF 24-70 f/2.8L II at B&H & Adorama for $2299.

EF 24 f/2.8 IS & EF 28 f/2.8 IS Both are still slated for the end of June.

Lenses / Patent: Canon EF 2.8x Teleconverter
« on: March 27, 2012, 07:55:35 AM »
Patent Time
A patent showing a new teleconverter has made an appearance. It appears to be a 2.7 or 2.8x TC. What effect woud it have on aperture? A 400 f/2.8L IS II would become 1120mm at f/8. All well and good, but the missing f/8 autofocus on the 1D X makes this one a bit strange with the current line of camera bodies.

Patent Publication No. 2012-47869

  • 2012.3.8 Release Date
  • 2010.8.25 filing date

Example 1

  • -83.98mm focal length
  • Expansion rate β = 1.996
  • Lens Construction 5 group nine

Example 3

  • -41.91mm focal length
  • Expansion rate β = 2.779
  • Lens Construction 5 group nine

Canon’s patent

  • Rear converter is to increase the focal length, F number, the residual aberration
  • When doubled, twice the lateral aberration, longitudinal aberration is 4 times greater rate of expansion, because the F-number is also double, longitudinal aberration is twice per depth of focus
  • Rear converter configuration consisting of three groups of positive and negative positive
  • Reduce the aberration of the rear converter itself

I really dig the shot, well done.

I can block sites, which I've now done with Ryther. I do NOT control what Google puts through the adsense network. The scam sites change URL's too, so it's an ongoing battle.

There's no such thing as an "entry level" full-frame camera...makes zero sense marketing/business wise.  The Cine-DSLR will obviously be full-frame.  I can see a market for a 1DsMkIII-esque studio replacement in terms of a 3D/4D high MP monster but not suggesting that is coming, however much more market for that than cannibalizing the investment Canon has made in the 60D, 7D (7D II) etc. with a $2,400 full frame camera...UNLESS it shot only stills which would make no sense really given phones are shooting 1080P video now.  The 5D3 is the "entry-level" full-frame camera if you want to use that term; and the 1Dx is the flagship full-frame camera, certainly room in between them for a studio, high MP body.  There will not be a 5DX, that was a creation of this site I think, not seen anything from Canon on a "5DX", the Cine-4K DSLR is not going to be in the 5D line, it is meant for an entirely different market, the market it was announced at, Hollywood, with the C-300.  There will not be a <$3000 full frame camera from Canon this year, period...if ever.

The 5D Mark II will remain current into the fall, and for the moment it's entry level. It also sells extremely well after all these years. Reports I have from a few retailers is sales haven't slowed since the 5D3 was announced. If anything there was a surge in sales. There is definitely a market for a $2000 full frame camera.

1704
This comes from someone that is probably the most accurate of any source with stuff months off from coming to market. Specs and the like are never decided this far in advance. I have heard there are multiple camera configurations in the wild right now.

If I had to wager, a 5D3 minus the AF, frame rate and build quality. $1999 anyone?

1705
Odds & Ends
A know source has mentioned a couple of things in regards to products coming in late 2012.

Mirrorless Announcement I’m told that Canon’s foray into the mirrorless world will begin in August with an announcement. Photokina is in September, so it makes a lot of sense to announce at the end of summer.

New Full Frame A suggestion that Canon will announce an “entry level” full frame camera in the fall of 2012. A true replacement to the 5D Mark II?

That would bring about 4 new full frame cameras in the span of about a year if we include the coming 4K DSLR. Most assume that will be a full frame camera.

EOS Bodies / Canon Cinema EOS 4K Camera [CR1]
« on: March 24, 2012, 09:39:58 AM »
Brief words
Received a brief bit of information regarding the upcoming Canon Cinema EOS 4K DSLR.

Apparently it won’t be available for purchase until Q4 2012 or early 2013. The announcement could come some time before then. Variations of the camera are in the wild, no specs are known beyond the 4K specification for the movie mode.

The form factor will apparently be in the form of a 1D style body as shown at the C300 announcement.

NAB 2012 is coming up in the middle of April, and we have heard nothing about a possible announcement before then.

EOS Bodies / Re: Disappointed in Amazon 5D Mark III Preorder
« on: March 23, 2012, 09:11:00 AM »
Amazon began shipping bodies on the 21st, and lots went out yesterday. I expect more will leave today. Unfortunately, I don't have a contact at Amazon to give a better idea.

EOS Bodies / Unofficial Canon Mirrorless Concept
« on: March 22, 2012, 08:56:17 AM »
A Canon mirrorless concept
We know a mirrorless camera from Canon is likely to appear in 2012. What form it takes is anyones guess. I am from the camp that Canon should do a higher end large sensor mirrorless along with a lower cost APS-C style camera.

David Riesenberg has done what I think is a fantastic concept design of a Canon mirrorless camera. Anyone at Canon listening?

The camera is based around the following ideas (Direct Quote)

  • Full Frame – Might as well be the pinnacle of 35mm. Especially if a new lens mount is required. Future proof.
  • 18.1MP sensor from the 1DX – This camera will not rob sales from the 1DX on form factor alone so it makes sense to use an existing sensor instead of a new one. Plus, it will make an excellent pair to someone with an 1DX.
  • CM-D Lens mount – That was the source of most headaches for me. Naturally, I wanted to design it around the EF mount for reasons that I don’t need to state but it proved to be very problematic. Both the flange depth and actual mount diameter meant that the camera needed to be much thicker and possibly taller to accommodate EF lenses. So this “CM-D” lens mount is roughly FD sized which keeps the dimensions close to the original and enables lenses that are not too huge.
  • 50mm f/1.0L “Kit Lens” – Fast primes. What can I say? I love them and they probably the best match to a system as I outlined above. So their existence is no less realistic that all the other items here. While I am far from being an optics expert, I designed this 50mm lens based on a combination of schematics of the Canon 50mm f/1L. FD f/1.2L and Leica f/0.95 so it should be a realistic representation of the dimensions of such a lens. It also features an aperture ring for direct control as well as an Auto mode for shutter priority or auto mode.
  • Viewfinder – Design wise, I knew from the start that I wanted to incorporate the prism hump of the AE cameras. It is a prominent feature that without it, the context of the design gets somewhat lost. At the same time, it is obviously not a technical requirement in mirrorless cameras so making it detachable while housing the EVF felt like the optimal combination of form and function. After all, if this is a camera for photographers, a viewfinder, even if electronic, is a must.
  • Flash Flash Flash – I regard flashes as an integral, must have feature of any system and I didn’t want to handicap its use in any form. Not when taking snapshots with the built-in one and not when the viewfinder is either attached or not.

Read more  and view tons of images of the concept

**NOTE This is an unofficial concept design. It is NOT a Canon Inc. concept

Thanks Saso K
