EOS Bodies - For Stills / Re: Posting about sensors and DR!
« on: September 24, 2014, 02:57:04 PM »
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 ...

PowerShot / Re: New PowerShot Digital Compact Camera Under Development

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.

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.

Lenses / Re: Lenses that you want Canon to release next
« on: September 17, 2014, 01:22:09 AM »

  • EF 2.8 200 IS  -  i tend to see 100-135 mm as "normal" with good close focus capabilties (1:4 would be great)
  • EF-M 2.0 50 IS  -  in a compact package with great IQ, flare resistance and good close focus capabilities. Shure, in my view a moderate wide angle but a good partner for a DSLR with 70-200 or 200mm prime

EOS Bodies / Re: How excited are you about the new 7D II?
« on: September 16, 2014, 12:51:46 AM »
The camera is very well specced on paper - except tilt display, touch screen and wifi which made it a "complete camera" for a few bucks more.
Very interesting: The correction of aberrations and distortion e.g. during movie mode with the EF-S 10-22 which has visible CAs.

But the real interesting "not-on-paper" specs are - for me - (1) very high IQ at low ISO, (2) fine IQ at higher ISOs and (3) a extremely reliable AF system. Reliable means that the AF does what I intend it should do.

If the per pixel image IQ is like that of my 40D I will have 40% more size (linearily) with the same quality: fine, might be my next main camera and replace one 40D and the 600D completely.

So ... just waiting for a bunch of reviews to filter out if this camera might be the right tool for me.


EDIT:
Forgotten to describe my degree of excitement: As you can see from my reasoning I am moderately excited. But this might change if I get hands on that camera and the excitement might growing while using a good tool over several years! 7D ii has the potential to do so ...

The original link (first post) says

 - RGB + IR photometry sensor of new 150000 pixels

If IR photometry means that the sensor can decide between warmer and colder subjects  - the 7D ii might be THE system for tracking living creatures by their thermal emissions ...

Cannot work like a IR (thermo) camera because the lenses do not transmit these wavelengths but perhaps it is sufficient to scan the near infrared for that purpose to get a hint where a "warmer" subject is.

Evaluating 150000 pixels for 4 colors and combining the data with a 65 field cross type AF sensor will use up the computing power of one DIGIC 6 I think ... now I understand why they have two of these processors.

This camera is more and more interesting IMO - not only by specs but by the clean and well known button layout - just for someone who owns a 40D and hates the ergonomics of the 600D (despite its good IQ).

Lenses / Re: What New Lens are You Most Excited About?
« on: September 12, 2014, 05:44:22 PM »
The OTUS 85mm lens is the most interesting for me in this line-up:
  * I like optimum quality and
  * the freedom to choose each f-stop depending on my idea about a photo and
  * the missing LOCA which I expect from a well designed apochromatic lens

Might rise my 600D to 15 MPix real resolution instead of the 9 MPix of the EF 2.0 100 ... but on the other hand: It's just 25% more linear resolution perhaps (!) resulting in 25%x25% larger prints with the same resolution.

So perhaps I will invest 4500 €/$ in 150 day trips to photographically interesting sites - a nice dinner included ...

29
No price yet?  $5K, $10K?

I think it will be priced similar to the 50mm OTUS because some effects might cancel others:
  (1) less lens elements and
  (2) smaller curvatures and
  (3) less special glass diversity BUT
  (4) larger lens elements/more glass/more housing

Just my 2 ct.

The problems I think Sony would have is that firstly I'm not sure theres massive demand for resolution above the existing 36 MP and secondly its questionable how there current(and future) FE lens lineup would perform on such a camera as there are already serious issues with the wider lenses with 24/36 MP.

Honestly I'm starting to think that Sony might be in panic mode with the threat of the camera(not sensor) division being shutdown hanging over their heads such is the rate of new releases.

In terms of real demand for photographic work/photographic expression : I totally agree.

But for boosting around "I can 50 MPixel" (for 4x6" prints for the family album) it is well suited and this might be a personal demand to own something with the hightest number availble. Same thing with hp of cars or sizes of houses ...
