The Canon 1Ds Mk 4, has been one of the most hotly anticipated new cameras for some time now.

Growing talk - and some credible rumours - of a Canon 1Ds Mark IV release date suggest we could finally see a Canon announcement for a Canon EOS 1Ds Mark III replacement as soon as this spring.

The continued interest in this camera has led to a flurry of rumours as to what the EOS-1Ds Mk 4 specs will entail. So while we all wait patiently for Canon to announce an EOS 1Ds Mark III successor, we have created this one-stop shop for all Canon EOS-1Ds Mark IV release date news and rumours.

Canon 1Ds Mark 4: release date

[Originally posted 20 January 2011]

Photographers looking to purchase a Canon EOS-1Ds Mark III will have great difficulty in finding one, perhaps suggesting an EOS-1Ds Mark IV release date will soon be announced.

Following a rumour by Northlight Images, PhotoRadar undertook its own research, which revealed that the Canon EOS-1Ds Mark III is out of stock at most UK and US retailers, and is even unavailable in Canon's own US and UK stores.

Long-rumoured to be replaced, PhotoRadar found that in the UK the EOS-1Ds Mark III is out of stock at Jessops, Currys, Dixons, PC World and a number of smaller retailers, according to their websites.

Amazon UK has one left in stock, at the time of writing, and Park Cameras, perhaps significantly, is selling its stock in the EOS-1Ds Mark III for £2,000 less than the recommended retail price. Other retailers, such as Jacobs, which have the camera in stock are also selling it at a heavy discount below the RRP.

In the United States, the Canon 1Ds Mark III is even harder to find. None of the major American retailers Ritz Camera, Best Buy, Camera World, B&H or Amazon US has the Canon camera in stock.

The surprise news lends further credence to the camera rumours that a Canon EOS-1Ds Mark IV release date will be announced, possibly as early as the first quarter of 2011.

Canon 1Ds Mark 4 rumours

[Originally posted 21 January 2011]

There are a lot of strong signals pointing to a Canon EOS 1Ds Mark IV release date in the near future. Perhaps the loudest signal of all is one that is hiding in plain sight: the fact that it is nigh impossible to buy a Canon EOS 1Ds Mark III!

Recent research by PhotoRadar found that the Canon 1Ds Mark III is not only out of stock at most retailers in the USand UK, but perhaps most significantly, it is being heavily discounted by those retailers who do have it in stock.

Introduced in 2007, the EOS-1Ds Mark III was the studio photographer's dream camera. Offering a resolution of 21 million pixels from a full-frame sensor, the 1DS Mark III had a high enough resolution - and in a tough enough body - to satisfy the most demanding professionals.

Fast forward to 2011, though, and the Canon 1Ds Mark III is matched in resolution by the cheaper Canon 5D Mark II, which offers a video mode to boot. The 1Ds Mark III can't shoot video footage, and its first-generation live view mode is nothing much to shout about.

In recent months, Canon has also been making noises about newer, higher-resolution CMOS sensors. All this adds up to a Canon 1Ds Mark IV release date at some point in the coming months.

2011 Canon 1Ds Mark IV release date probability: 90%.

But we probably won't see a Canon 1Ds Mark 4 release date until spring 2011.

Canon EOS-1Ds Mark IV likely specs and features:

- 30 million pixel sensor
- Improved Live View
- Full HD video (1080p)
- DIGIC 5
- Integrated wireless flash transmitter
- As we suspect Canon may want to market its robust EOS 1Ds Mark IV release towards filmmakers, we think the 1Ds Mk IV will boast a raft of filmmaking features - everything from a microphone jack to, perhaps, editing software

Canon 1Ds Mark 4: what we want to see

1. Higher pixel count

The EOS-1Ds Mark IV needs a higher pixel count. The competition currently peaks at 24MP, so we can expect a Canon 1Ds MK IV release to at least match this, but possibly push to 30MP or more. After all, Canon announced a 120MP APS-C sized sensor last year.

2. Video technology

It may not be as important to studio photographers as it is to photographic journalists who tend to use the EOS-1D Mark IV or the EOS 5D Mark II, but we expect the EOS-1Ds Mark IV to be capable of recording 1080p movies.

3. New processor

As the EOS 1Ds Mark III features the last generation of Canon's processor (twin Digic 3 units) its replacement will contain the latest version, currently Digic 4. But who knows perhaps there will be a new processor?

4. High sensitivity settings

High sensitivity settings aren't as important to studio photographers, but a maximum expansion setting of ISO 3200 is pretty low by current standards; it likely will be higher for the EOS-1DS MK IV release.

5. Continuous shooting

Canon's EOS-1D Mark IV has a maximum continuous shooting rate of 10fps. The Canon 1Ds Mark IV release is unlikely to be able to shoot at anything near that rate and will probably top out at the same point as the camera it replaces - 5fps.

6. Higher resolution LCD

Amazingly the 1DS MK III's LCD screen only has 230,000 dots. This is sure to change with a EOS-1Ds Mark IV release. Expect to see a dot count above 1 million, and at least 1,040,000 dots.

7. Articulated screen

Studio photographers often shoot from awkward angles or want to maintain eye contact with their model, so an articulated screen could be quite a bonus. It would be a first for true pro-level camera and only the second Canon DSLR to have such a screen.

8. In-camera image rating

Arguably less important for the studio based photographer, but as Canon has the technology it seems a probable inclusion in the EOS-1DS Mark IV release.

9. iFCL metering

Canon's new metering system is bound to be a feature of the EOS-1Ds MK IV release, but we suspect that it will be possible to break the link between it and the AF system.

10. Built-in wireless flash control

Invaluable for studio photography, using radio waves please.
