EOS Bodies - For Stills / Re: Same card shared by two cameras
« on: July 01, 2014, 08:16:08 AM »

Each camera will create a unique folder under the DCIM folder and save images in that location. Unless you change the file format, it is not "IMG" by default so the naming sequences will be unique.

Given the relatively low cost of memory cards, it would be easier to buy another one.

My observation is different. Both my 70D and M save photos into DCIM/100Canon by default, unless I set it to other.

It is not the cost of cards matter that much. I just want to rule out the possibility picking a wrong card then old file been overwritten.

Thanks for the above replies.

I have 3 cards, each camera has its main card and the third one is used as a backup for both.
I'm also considering bring all cards with one or both cameras while travelling. I don't want to format every time I change cards.

Just did my experiment, without resetting counter, I made a copy of IMG_1234.CR2 into IMG_1235.CR2 and put back the card. When another picture taken, it was named as IMG_1236.CR2.

So my worry wasn't there.
In fact, I can select another folder to store the photos on the same card. So even the file names will still be continuous. But I'm lazy to have to do that every time after a format: )

EOS Bodies - For Stills / Same card shared by two cameras

I have both EOS M and 70D. I'm thinking whether I can share cards among them.

Google search seems suggesting it will be fine.
But I'm curious, both camera by default store CR2 files into same card and both would be IMG_xxxx.CR2
What happen if the 70D trying to write a CR2 with a same name already on the card?


EOS-M / Re: EOS M for travel

There are a number of reviews around the web.
From DPR

"Canon is making grand claims for the 11-22mm's optical quality, and saying that its 12 element / 9 group design will offer significantly better image quality than the (already well-regarded) EF-S 10-22mm"

I think it's true, probably the best if you're happy with the F number.
What wasn't mentioned in many reviews was that the distortion control is also excellent.

EOS-M / EOS M for travel
« on: August 30, 2013, 12:23:25 PM »
I guess many may consider a EOS M for travel usage. It's so much lighter, especially when you start to bring more lenses. I visited Perth west australia with EOS M while leaving my DSLR at home.

Here is my 2cents report

Get a EOS M + EF M 22/F2. The combo itself is cheaper than any lens mentioned above?
If you're happy with EF-S 10-22, EF-M 11-22 IS seems be better and cheaper as well.
Taking this option you gets better resolution, better ISO.
For landscape on crop, EOS M should be more than just capable?

My wild guess.
1. The EFs 10-20 is selling well in US, bringing a higher margin.
EF M 11-22 will be better in performance, lighter, equally or better in build, and much CHEAPER...
I sold my Sigma 10-20 soon after the 11-22 news release..

2. EF M is selling much better in other part of the world compared to US.

Google translate should take the credit (or blame for poor translation), I'm too lazy to translate  :D

What surprised me was no mention of the sensor fabrication process in the English news release. Even worse they mentioned 70D high ISO is on par with 60D.
In general the official 70D Chinese release provides much more info compared to the English version.
The official Japanese release seems double confirmed the new process.

"Advanced technology to support high sensitivity, low noise and a wide dynamic range.

Aims to improve the aperture ratio of the photodiode of the CMOS sensor in the introduction the new miniaturization process in CMOS semiconductor process. Expression that take advantage of more, a wide dynamic range and high sensitivity and low noise is now possible. Moreover, adoption conjunction with photodiode structure having excellent photoelectric conversion efficiency, the pixel transistors improved to reduce the noise of the pixel portion. Improve the S / N ratio, and high ISO sensitivity. In addition, gapless micro lens with excellent light collection efficiency has also contributed significantly to the high sensitivity."

We'll have to wait and see how these marketing press really translate to

If you read the 70D Canon China news release,
the following is Google translate result

"In the semiconductor manufacturing process, while improving fine processing technology, each pixel arranged on the surface to improve the collection efficiency of the micro lens, and shortens the distance between the photodiode and improve the photoelectric conversion efficiency of the photodiode. It also improved the pixel transistors, in more than 20 million pixels at the same time achieve a high sensitivity, low noise and wide dynamic range. Approximately 20.2 million effective pixels amount of data can be achieved under the 300dpi A3 format printout, cut out the image locally you will not lose a sense of resolution, etc., with a variety of advantages. "

I can read Chinese. It sounds to me a new fabrication process. Though we have to wait and see.
Btw, the ISO 3200 sample doesn't look bad

Usable hotshoe 35mm OVF starts from 50USD for a Soviet era stuff to xxxUSD for Leica.

EOS Bodies / Re: 70D or 6D
« on: July 05, 2013, 02:38:37 AM »
If main focus on landscape,

6D + 24-105 is a good choice.

Otherwise you can also consider add a mirrorless system
EOS M + (to be released EF M 11-22, EF M 18-55 also not bad)
EF M 18-55 STM seems sharper than the EFS lenses in the same range.
In APS C, to go wide, EF M seems better than EF S for now and future. I just sold my Sigma 10-20.

EOS Bodies / Re: EOS-M or 100D
« on: June 25, 2013, 03:18:25 AM »
I'd recommend EOS M over 100D unless you really need certain performance from DSLR.

1. Do you have another DSLR? or 100D/EOS M will be your first

2. What's your main use case?

EOS-M / Supermoon test
« on: June 24, 2013, 01:10:17 PM »
Not really serious about supermoon shooting, I just wanted to try out the EOS M and see how it handles such task.

70-200 F4L IS works quite well with the EOS M. AF reasonable fast, even with stock v1 firmware.
The shot step photo is here

I like it.

EOS-M / Re: New Lens, New Firmware for EOS-M
« on: June 12, 2013, 05:21:02 AM »
Hopefully the Firmware download adds a viewfinder.

That's hilarious.  Why don't you just buy an SL1 instead and give us peace?

Hi Paul, sorry if my comment offended you, not my intention, just some Aussie Humour at work, not always appreciated i know, I'll try to restrain myself in future.

Apologies bud, maybe having a 'chippy' day here.  If you must have a viewfinder then the M is clearly not the camera.
Check here, OVF with EOS M.

EOS-M / Re: How many people actually like the EOS-M?
« on: June 11, 2013, 04:34:22 AM »
Bought and like it.

1. For current price, can hardly find another one better. Especially for Canon EOS users as backup or travel kit.
2. AF not as bad as some reviewer said. A new firmware coming.
3. Lenses, 18-55, 22 are among the best in class, 11-22 coming soon. Adaptor to EF lenses with full functionality.

The EOS M body itself is not as good as Sony Nex 7 or Olympus OM D. But it costs only a fraction of those. You can update when EOS M Mark II or III out.
