The best message is IMO: The 7D ii technical image quality isn't much behind other options in terms of crop cameras. It reproduces textures very well despite of the little bit more noise compared to other options.

I have to check only if I
  - LIKE TO WORK with that instrument (probably YES!)
  - need/want the spectrum of capabilities the 7D ii own (YES!)
  - still have lenses for EF(-S) mount (YES!)
  - want to carry the load (900g + lens) (YES! most of the time)

After observing that leafs turn rapidly from green to brown in the last decade I have to search for other plants showing reds in autumn. Except the second image of a "german" maple (?) leaf.

Lenses / Re: What telephotos do we own?

I rest my case for a new version of the 400 F5.6 ... it's coming in 2nd as the most popular lens.
New electronics. USM and IS ... latest glass coatings, perhaps a tweak here or there to the optics, a lick of new paint .. oh and the most important issue I think is a closer min focusing distance in line with the 300F4 or the 100-400 and it'll be a winner.
I'm stuck using a 70-200 2.8IS and at times a 2xIII, but wanting the "prime experience" with a clean, light, straight 400.
Not that keen even on the new 100-400, but may only get it for it's close focusing .. if it's the same as the old one at 1.8m. I don;t really need to lug around the extra stuff, as I really just want 400mm
Does sales have to slow down on a lens for Canon to think about a replacement ?
It still seems to sell well ... a friend of a friend only posted two days ago a pic of his new 400F5.6 sitting on the front seat of his car driving home from the shops after just purchasing it.
So for me it's a toss up of the closer focusing of the 300F4 or the reach of the 400F5.6 ... but the bigger issue is both lenses are so old they both are long overdue for a re-vamp ... and I want the new re-vamped models, not going to buy the older version no matter how good they still are, they are due for a new version of both.

Three years ago I was in the same situation: 100-400 or 5.6 400 or wait vor a mark ii version ... I bought the 5.6 400 because the price gone up (1500 Euro) but I had one dealer who sold it for about 1200 Euro. So far it was a reasonable decision because no mark ii version hit the market in the meantime.

Your points are very good: minimum focus distance and missing IS limit the 5.6 400 but on the other hand this sturdy, compact and well designed lens gives you at least a 1 or 2 stop advantage compared to a not so sturdy design.
The IQ is stellar - just atmospheric turbulence limits its sharpness/contrast/IQ moderately to severely depending on the weather conditions/local conditions. So the 100-400 will give you the same IQ in the field most times I think. And I like to have the ability to use f/11 @ 800mm with a 2x TC (mark i) which works very well with this "lens of the 1st hour".

You have the 2x TC so the 4.0 300 might be an option for you with a 7D ii which has AF on centerpoint with f/8.0 @ 600mm ... but: no easy decisions at all ...

Last point: Check IQ under field conditions between your 70-200 with 2x TC versus 5.6 400 if you have access to a 5.6 400 - perhaps the difference isn't that big and you do not need to lug around to much gear.

EOS Bodies / Re: Patent: Improved Cooling for DSLRs
« on: September 28, 2014, 04:06:46 AM »
I would translate "heat imaging device" into a pyrosensor equipped camera to take infrared images of heat sources ... but maybe it's a translation error and "hot imaging device" was meant.

Might be 4k but might also be the need to cool the imaging device integrated (hopefully!) electronics to decrease read noise ... or its adressing both?!

1 Image quality most times absolutely sufficient for MY purposes
2 Very good lenses in terms of the "right IQ" as a combination of all parameters
3 Ergonomics and knowledge of its ergonomics
4 Magic Lantern - compatibility: Using FD* lenses on EF-M mount via adaptor (or EF mount after conversion) with ML focus assist systems is easy!



* Just exploring the FD 1.4 50 S.S.C. - not an OTUS but very good just at f/1.4 and excellent from f/2.8 with EOS M (equivalent to 50MPix on full frame!)

Are you using anything special for the  FD - M mount? I have a large collection of FD lenses that are crying out to do something useful and I have an M. I know there are a million FD - M convertors on eBay and most are pretty cheap and there is no glass or real engineering in them, so just wondered if you had a recommendation.

I have the "quenoX FD-EOS M" adaptor - nothing special - for roughly 40 Euro. It has NO optics and a ring to switch to close/open the aperture. No issues until now. Infinity focus is no longer the hard stop - so you have to use focus aids just for infinity. But: It let's you focus to infinity without introducing optics!

One thing that might be interesting for you: It has NO tripod mount on the ring. There is a 10mm long cylindrical section on the adaptor so it might be possible to get something but the adaptor is not prepared for it.

Here a link to enjoyyourcamera.com (I bought it via amazon):

One hint about focusing:
EOS M isn't the best camera for manual focusing but ... Magic Lantern will help a LOT. It has a live view "high contrast visualisation" mode where coloured dots show the regions with highest contrast - the "sharp" regions. And it can insert a magnified region of the sensor's center. Tipping the shutter release can be used to switch between both modes which work very well.- after a t
EOS M seems to be supported very well - I installed a nightly build from the download section!

EDIT:
1) If you start using an adapter you have to tell the camera that the shutter release works without lens
2) I use Av mode + Exposure lock via
  • button if necessary. Full manual mode doesn't give me useful exposure preview on the display!

2000 Eure per month are sufficient, 3000 Euro per month give you some headroom, 10000 Euro per month give you much more headroom to do things you like - would you say "no"?

Put like that, no.  But...what if to get that 10000 € per month, you had to move to and always stay within the city limits of Paris – not the one in France...the one in Texas.  Or give up one of your kids. 

So, would you still choose that extra headroom if it came with significant strings attached?   Maybe you would prefer to get the additional headroom without any changes to your life situation...in that case, you could post on an Internet forum how much you'd like that extra 7000-8000 €, and hope your boss reads your posts and gives you that big raise.

I haven't spoken about additional restrictions ...

In that case, I agree...as I already stated.  :)   We've established that having more DR is desirable.  Now what?

Even MORE DR of course :D

Touché.  Yes, of course...bring on the near-noiseless sensors and 18-bit ADCs.

But, one step at a time.  More DR is desirable.  How exactly do we go about getting it, particularly with no additional restrictions?

Building sensors in the 3rd dimension to enhance full well capacity by a factor of 10 -> its roughly 3 times more DR at low ISOs if everything is left constant (except price due to higher production cost). I think this will happen within the next decade.

PowerShot / Re: New PowerShot Digital Compact Camera Under Development
« on: September 24, 2014, 01:34:42 PM »
Now add in my 'old' idea: give this boogar a rechargable lithium battery that is shaped like 4 AA batteries; the best of both worlds.

4 AAs produce 4.8V (rechargeable) or 6.0V (alkaline).  Lithium batteries produce 3.7V (1 cell) or 7.4V (2 cells).

How are you going to handle the different voltages and how are you going to estimate remaining capacity when you have different voltages and different discharge characteristics?

Using 7.4 V Li Ion or AAs (4.8 V or 6 V) batteries and an internal voltage of 3 V - a step down converter circuitry can handle that with efficiencies of roughly 85 % . Or use a combined step DOWN / step UP converter with less efficiency.
The camera has to be informed by the battery (or menu) about the battery type to know it's discharge characteristics.

But - IMO - to expensive / complicated (choosing battery type in menu) for users who like the concept of a easy to use wide range zoom ...

Some of the "DR of Canon sensors is enough" claimers shifting my opinion more and more to "I would like 18 stops DR and a precise 20 bit ADC".

As scientist (physics) I like to have data to be of the best quality which is possible. Sony's Exmor sensors deliver much better raw data than Canons sensors.

For me a 40D or 600D delivers very good quality most time. But nothing speaks against 4 or 6 stops more sensor DR and an adequate ADC which makes transitions even finer.

Shure, most display options (TFT, paper, alu dibond, ...) are limited so 11 stops DR are sufficient most times.

But thinking about OLED monitors I see that 15 stops are easily possible. Seen a LG OLED monitor last week and this is a totally different world with gorgous black levels ...

The more bashing of those who like the concept of more DR the more I see more DR as relevant in some situations* and helpful for overall IQ with respect to the future of display media options. Might result in waiting another round of camera development and switching perhaps to a body where I can use my well trusted canon lenses ...

The bottom line is that mirrorless will remain a niche at least in the USA.  Professionals want the best quality and best ergonomics, while consumers want the best deal and best practicality.  Mirrorless fits neither of those formulas, thus it is doomed to third tier niche status that may retain a devoted fanbase but will never make it beyond that.  The very best scenario for mirrorless advocates is a hybrid camera (as an optional EVF mode to augment a traditional OVF viewfinder), but based on the anemic mirrorless sales it appears that will not be a necessary investment for any of the big players.

Let me put the situation to you differently.

If tomorrow Canon came out with a 5DIV and a EOS-MX, where both were full frame and using the same senor but the MX was mirrorless (with corresponding weight savings, etc), I'd buy the MX in a heart beat and never even consider the 5DIV. I'd also never buy another EF lens that was for non-mirrorless cameras.

The size and weight differences are not inconsequential and if I think to the future then at some point I'm going to say "I'm sick of lugging around fat ass DSLR bodies and lenses when I can use something smaller and lighter."  If I buy another DSLR it will either be the last or next to last DSLR that I ever buy.

Now maybe that's further into your future than you care to think about but not for me. In 30 or 40 years, what do you want to have hanging around YOUR neck?

I think DSLR an mirrorless cams will coexist at least 2 decades as an offer of the large camera brands. The whole live is a large heap of compromises and sometimes there is no logical OR but an AND:

DSLR: Action, "looking throu cam to check subjects without power consumption", etc.
mirrorless: If lower weight is important, tripod work, etc.

EOS Bodies / Re: Long shot - Anyone tried using FD lenses on an EOS body?
« on: September 21, 2014, 10:33:32 AM »

[...]

The major drawback of the EOS M is the fact, that you cannot find the right focus setting via the display easily. A electronic viewfinder of a future EOS M would be very helpful for that.
But if you use more or less static objects/subjects using the FD lenses via EOS M might be a good way to experiment with these older lenses.

[...]


actually on the M if you install magic lantern and enable focus peaking it lets you use manual focus lenses incredibly accurately

Thanks for that tip - I was always confused if the EOS M is supported or not and if - how good it is supported. Focus peaking alone was worth it - after a sales offer for a 32 GB SD card I decided to check it (instead of visiting Photokina near my location).

Focusing is really fast and - more important - very reliable, as you stated. FD 1.4 50mm S.S.C. is now a very good and FAST lens ;)

Thanks again and best regards - Michael

EOS Bodies / Re: 70D or 7D MK II
« on: September 20, 2014, 06:25:17 PM »
If I use two cameras together I would always be interested in (very) similar ergonomics between both. Usually I have 600D and EOS M with me - both have very different ergonomics but just 40D and 600D are separated by a lightyear or so.

If missing wifi, tiltable screen, 3x digital zoom and weight (+ price) is a non-issue the 7D ii might be the right choice.

I am thinking myself about an upgrade
  IQ-wise AND
  AF-performance wise
and I am shure the 7D ii will win (70D is no option for me because I like the joystick controller of my 40D so much) - and I like compact solid bodies ...
Much better AF is needed for outdoor macro with AI servo to let the focus adapt permanently - it is always a little bit windy. The widespread AF fields and the cross type sensors might help a lot.

EOS Bodies / Re: Sample Images From the EOS 7D Mark II
« on: September 19, 2014, 12:15:09 PM »
I'm stunned.  The 7DII matches or nearly matches the 5DIII even at ISO 12,800!  Wow.  It's still no match for the 1D X at higher ISOs, but I can't believe they have pulled this out of an APS-C chip.  It looks like I might have to get into the pre-order line after all.

EDIT - I must have used the Comparometer(TM) incorrectly.  The performance still looks quite good, though, and a big improvement over the 7D.

I was worried about your first remark which you corrected just few seconds before. Your posts make always sense but this one was strange  ;)

Compared to the 7D I see a good advantage but the images in the comparometer made with the 600d/T3i look not too bad compared to the 7D mark ii.

If I should buy the 7D mark ii I will buy it for it's ergonomy (600d has beeing euphemistic inferior ergonomics) and AF system if it shows great performance  - not sheer IQ. And things are not easier now: perhaps a 6D for HQ imaging?
I guess I need more caffeine!  The one other thing I noticed is that the 7DII seems to hold color saturation a bit better at high ISOs.

I wouldn't hesitate to buy the 7DII at all.  In all of the years I've been shooting wildlife, I've rarely shot anything over ISO 6400 (and that's before sunrise) and within 30 minutes of sunrise, I'm usually at ISO 1600 or less, depending on the lens to get 1/500s or higher.  Even with a Rebel and the IS-less and slow 400 f/5.6, the vast majority of my shots were at ISO 400 + or - 1 to 2 stops.  For sports where you need to be at 1/1000s or higher, it will be a bit tougher, but I think the 7DII is still up to the task from what I've seen.  Besides, noise isn't the end of the world and I'd rather have a noisy shot than no shot.  The AF, frame rate, etc. will give you much better odds of getting the shot.

Good remarks far from "counting pixels":
Perhaps a combination of a 7D mark ii with a high resolution camera will do for me - I really like the idea to have a ultra reliable AF system for faster action - just "action macros" of insects ... hopefully the 7D mark ii convinces in this respect.
A high resolution camera for other purposes might be added later ...

are some canon fanboys so desperate that they dream with open eyes already?

the quality is exactly as the 70D.... the sensor is not improved at ALL.
the small difference you may imagine(!) could have all kind of reasons.

canon is playing it´s old game.
and i bet you will see this sensor until 2017 in entry level DSLR´s from canon.

meanwhile every APS-C MILC offers better image quality.

Perhaps 2017 is wrong - it might be 2019

but

A camera which OFFERS better IQ isn't always a guarantee for BETTER IMAGES

Ergonomics and reliability of its subsystems for exposure metering and AF might be of much higher importance depending on the purpose ...
And I have a set of lenses which I am very satisfied with.
