On Canon EOS 6D preview (1035 comments in total)

So poor specification! For the same price as Nikon D600, who will buy Canon 6D? Canon is certainly out of competition. I believe Canon will slash the price to $1500 after a month.

I wish if SONY A57 had flash sync speed 1/200 or 1/250 sec like its competitors (Canon T4i, Nikon D5100, etc). What is the barrier here (patent, SONY technology, etc)? Why does SONY love 1/160 sec? Also, A57 has weaker built-in flash (10m A57 vs 13m T4i). I don't get it.

AP7: Good news: Nice pricey camera with "Leaf Shutter" that can sync up to 1/2000 sec.

Bad news: In bright day light, the maximum aperture that you can use without blowing out background is f/3.5 at 1/2000sec and ISO 100 (according to Sunny 16 rule). The flash guide number is 6m. So, it can only cover 1.7m or 5.6ft. If you subject is 15ft away, it will be 3-stops under exposed. Therefore, it is not so useful for daytime fill flash. Why can't they put a flash with guide number 13m (available in most DSLR camera) at least or shutter speed 1/4000 sec to get full advantage of leaf shutter?

So, even if it deviates by a stop, still GN 6m flash cannot lift the shadow, so my original post makes sense for fill flash situation.

@JackM, You said that you don't use fill flash. So, we should not be in the same line of discussions. Show me a back-lit picture (with exif information) in the beach using fill flash.

Sunny 16 rule is well established in all camera meter. I recently used my camera in Niagara Falls and Lake Huron beach around noon, and found that you exactly need f/11, 1/200sec exposure at ISO 100 (no deviation from Sunny 16 rule requires for proper exposure).

So, saying that Sunny 16 rule is wrong for proper exposure calculation is just a lie. If you take picture in the shed and don't care about background, that is different thing.

CameraLabTester: The real WINNER for this camera is the Shutter!

The leaf shutter is within the lens and can sync up to 1/2000 speed!

It will have a sound that is super hushy quiet, sushy nice.

Leaf Shutter sync 1/2000, this alone blows away any competiton.

Now Sony has to beef up it's service support confidence to woo the CanoNikoners...

.

If you calculate exposure in bright day, at aperture f/2.8, you need 1/3200 sec shutter speed and at aperture f/2.0, you need 1/6400 sec shutter speed (without blowing out background). You can only use maximum 1/2000 sec shutter speed at f/2 when the light is 1.67EV under the bright day light.

The maximum possible aperture in bright day light without blowing out background is f/3.5 at 1/2000sec. In this situation, the built-in flash (with guide number 6m at ISO 100) that Sony RX1 has can only cover (provide fill flash) 1.7m (5.6ft). If your subject is 15ft away from the camera, it will be 3-stops under exposed compared to properly exposed background.

@JackM, Be honest with yourself. I just showed some practical and very useful calculation. Did I make any errors?

Here are some more calculation for you:

Without blowing out background, if you want to use f/2.8 (at minimum ISO 100), you need 1/3200 sec shutter speed (and if you want to use f/2, you need 1/6400 sec shutter speed). So, for proper fill, flash guide number should be 13m that will cover up to 15ft.

OK, you at least got some case where Sunny 16 rule is applicable (such as beach, etc.) and maximum aperture is f/3.5. Even if you take f/2.5 in your calculation, the tiny built-in flash is 2-stops under exposed.

Well done Fujifilm ! You did it what other leading manufacturers (Canon, Nikon, Sony, Pentax, etc) could not able to do!

In reply to:

marike6: The review DOESN'T recommend a Panasonic G3 or EPL-3 as it did in the conclusion of the Nikon D3200 review. Why the double standard since the both DSLRs were criticized for their slower LiveView performance? Perhaps in this case the reviewer understands that it's a DSLR and the majority of users will be using the VF.

Regarding DR, "lags a bit behind" is a huge understatement since a camera like the D3200, D5100 or Pentax K-30 provide a full 3 EV more dynamic range than the t2i, t3i, t4i's 18 mp sensor. For a user with existing Canon lenses this is an issue they'll have to deal with. New users would be better served by a DSLR with a more modern APS-C sensor like one of the above cameras.

But the T4i should be popular with the Vimeo HDSLR crowd although it still has a somewhat soft look in video mode with moire / aliasing issues from previous Rebel models not adressed. For photography, you can get a K-5 or K-30 or a mid-range Nikon, all better choices, for this price.

@Josh152

I agree with you on DR issue, but I was replying on Live View issue that DPR put emphasize on entry camera such as D3200.

Also, Nikon has slight edge on high ISO.

But, Canon has some more features that you may only get D7000 or higher Nikon DSLRs, such as, High Speed Sync, DOF preview, live histogram, Mirror lock up, etc. Also, Canon has better video quality and manual control. Someone who want to grow may miss these features at a later time. Nikon style is to upgrade.

Not all the issues are mentioned in the review.

Simple, T4i and D3200 are not in the same category. While D3200 is entry level, T4i is mid level camera. D3200 should be compared with Canon T3 or upcoming Canon T4 (if any). Don't through question blindly.

Cons 4: "Using flash with Auto ISO enabled results in ISO 400 even in bright light conditions"

Shame to Canon for failing to implement better Auto ISO algorithm. I have seen the same tendency in my T2i. In bright day, ISO 400 is selected for no reason.

Auto ISO/(Manual ISO as well) should have at least 1/3EV finer increment like other exposure parameters, Aperture and Shutter speed. In bright light (or in any light), minimum possible values of ISO should be chosen (1/3EV increment).

Come on Canon, don't be lazy to implement it. Your processor is not that slow to handle little advanced algorithm. Its not hard to change the algorithm that dynamically choose ISO like Aperture or Shutter speed.

In reply to:

motobloat: What is really hilarious is that they are recommending various lenses over the 18-55 VR, but they haven't actually tested ANY of them except for the 18-55 VR.

DPreview, if you are going to make claims, support them with evidence. Where are your reviews of DX standard zooms?

* Niikon 17-55, 16-85, 18-105?
* Sigma 17-50 and 17-70?
* Tamron 17-50? Tokina 16-50?

Thank god for other lens testing sites. DPreview, call up your corporate overlords and get some money to hire some more reviewers.

Did not you see the samples taken by other lenses?

marike6: The Pentax K-30 just received a "Highly Recommended" from ePhotozine today.
And they don't once mention the Lumix G3 or any other ILC preferring to not compare oranges to apples as this review does liberally and somewhat puzzlingly.

Pentax K-30 is not an entry level camera. So, comparison with Panasonic G3 is irrelevant there.

I hope to get a K-30, such a fantastic camera and price point !

In reply to:

looker: Since the D3200 is for beginners, I'm even more glad to be going with the Canon Rebel T4i, because I'm no beginner.

Buy Canon T2i. It is much cheaper and gives you more features that you'll find useful as you are growing.

If you start with Nikon D3200, you need to replace camera body by D7000 to get the same features (such as, auto exposure bracketing for HDR image, Auto FP/high speed flash sync for daylight fill flash at lower f-stops, mirror lock up to mention a few) that T2i offers.

Beginner may not know about this at the beginning, but later they may regret.

Also, keep in mind telephoto zoom and affordable prime prices for both camera in case you may want other lens than kit.

On Canon significantly improves EOS 7D with firmware v2 article (296 comments in total)
In reply to:

AP7: I wish if Canon could update firmware for T2i/550D to incorporate:

1. In-camera RAW editing, creative filters, jpeg editing
2. Maximum Auto ISO setting
3. Manual audio adjustment
4. Focus peaking

Come on Canon, millions of T2i users around the globe would be highly grateful and royal.

But Canon is not going to replace my T2i with newer T3i for free (if they update firmware, T2i users can get it for free), and I cannot buy another camera every year.

BTW, Canon T2i is still a current model as you can find it in Canon USA website. Canon does not replace model like Nikon or others, rather older model sits below newer model.

Even after adding those features, T3i and T4i have enough additional features to sell them for more. In camera, HDR option would be also good to have.
