I think this lens is far from a no compromise lens:
  * LARGE
  * HEAVY
  * VERY EXPENSIVE
but ... different needs = different style of compromise(s). In some situations a 1 kg perfect lens IS MUCH MORE APPROPRIATE than a 300 g standard "equivalent"!

I am looking forward to test the chrome ring FD 1.4 / 50 which is small, light and waiting to be reused since 2000 with my EOS M which I bought today. "Digital" will show its weaknesses (optically) and I see low contrast/a slight halo + longitudinal CAs. My need: low DOF photography and/or low light photography - so these weaknesses might be negligible.

An interchangeable sensor is a good idea, but
  - it requires to change the processor too because IMO sensor + processor = film replacement - but that doesn't drive the price too much.
  - replacing a sensor by a customer needs a high precision sensor fixture to bring it in the same plane as the replaced sensor

I think it is possible to do this for 200 or 300 $/EUR more on a medium class camera, let's say 1300 $ instead of 1000 $. I would really appreciate such a system - specially if a monochrome sensor is available. Thinking (better dreaming) of ~ 20MPix with 12 or 13 bit DR and superior sensitivity, 2 EV more ISO sensitivity and working red filters for landscapes ...

Technical Support / Re: White balance, how to determine?
« on: August 14, 2013, 05:08:59 AM »
I shoot raw and use always the "sunlight" white balance setting to keep things comparable.

Afterwards I correct - if necessary - the color temperature (using DPP, lightroom will have it's equivalent) to a value which suits my needs.
I too observed the color shift in afternoon light and it muddle up different greens to a "greenish-yellowish soup". Shifting color temperature from 5200K (daylight) to sth. between 4000K and 4500K gives IMO better colors. But I do not try to overcorrect the values - 3500K might be correct for such cases: I like to leave a bit of the warmer atmosphere in the image to conserve my experience (or colder ambience if the light was blueish).

A major prerequisite is a constant lighting of the surroundings of the monitor and to "calibrate" your eyes to grey or white regions of the computer screen.

Best - Michael

(BTW: you use a great lens set with larger gaps which can be filled by using your feet ... :)

Lenses / Re: Does it make sense to keep my EF 100mm f2.0?
« on: July 28, 2013, 08:58:50 AM »
I was in a similar situation, but I choose the non-IS 100mm macro lens because of similar (or slightly better) overall IQ and I will keep the 2.0 100 lens:

first time i hear that the non L version has better IQ... i highly doubt that.
every review i have read so far tells the L is slightly better.

equal maybe but the non L better? that is stuff people tell themself so they donĀ“t have to buy the more expensive L lens. ;)

A late reply but now it's there :)

APS-C comparison between both (50D) (1st is NON IS version)

FF comparison (5D mk ii)

http://www.photozone.de/canon_eos_ff/458-canon_100_28is_5d?start=1

The differences are marginal - but the NON IS shows much lower CAs and a better uniformity of sharpness which is important to me because I like compositions where sharpness is needed at borders/in corners @ f/2.8 or similar.

As Hesbehindyou remarked - sample variations play an additional role.

Lenses / Re: Canon 40mm or High-End Compact?
« on: July 28, 2013, 03:21:48 AM »
After I owned the 40mm I rarely used my S95. Iused it a lot with my 40D, IQ is great, 65mm equiv focal length suits my needs very well. The 40D with this tiny lens is a VERY compact system which is comfortable to "wear". If I ever go into FF it will be my "moderate wide angle",

EOS Bodies / Re: An Update on the 75+mp Camera in the Wild
« on: July 26, 2013, 03:51:37 AM »
75MP + high frame rate might lead to the conclusion that this camera uses a "three subsensors per final pixel" design - as others mentioned here:

Using 3 x 25 sensels for R, G and B avoids the calculation of the final image from the Bayer patterned raw data. I don't know how much processing power is needed for Bayer sensors but if you want to to it right it might be a lot.
Using clean RGB-data for photos or video means just storing numbers.
Reading out three layers of a sensor independently eases the readout process and AD conversion by simple parallelization ...

Just my 2ct

You are all wrong.... This will be the 7DII..... and all for less than $1800.00 :)
...

Why not? And with a FF sensor based on the beloved 7 D 18 MPix sensor:
1.6 x 1.6 x 18 = 46

There will be NO camera with a 75+ megapixel FF sensor.

Shure? While smart phones get 40+ megapixel tiny sensors?

I tried the Digital lens optimizer of DPP (just available for a few lenses) and I see very good quality with the 10-22 on a 18 mpix sensor.

Not that I am lusting for 75 megapixels or more - 20 GOOD megapixels are sufficient for me (and a lot other too) but I think it is a possible future of FF DSLR - and a likely one.

9 years ago I got an 8 megapixel DSLR and was amazed at how big the images were and the detail involved. 8 was a big thing! Now I have 18 megapixels.... it's about time for ALL DSLR's to take a jump up.... 40 is the new 20... but 75!, that sounds like an attack on medium format.

That's true and just today I am amazed by the 10 MPix of the 40D ... just a good beamer/monitor with at least 5 or 6 MPix is still missing/not available for mortals! What a mismatch between cameras and output devices ...
Just wait a bit. Apple have a retina 27" monitor in the pipeline - 5120x2880 resolution, or 14.7MP. If you want to avoid upscaling, and crop the top and bottom off your 3:2 photo to fill the 16:9 display, you'll need a minimum of a 17.5MP image to start with. To be fair, 75MP isn't needed for that.

Great - that sounds interesting! I will start to save money for that display ;)

Ugh, with a RAW file size of what? 120MB?

So?  Storage is cheap, and my computers are fast.  ;)

I upgraded yesterday from Pentium 4 3GHz-PC to a Core i7 CPU-Machine: What a progress ... its computing power is great but data transfer might become a bottleneck during backup etc. ...

... or 75/2 = 36 million image pixels with Dual Pixel AF  ...

But 75 million image pixels / 4 means roughly 18 Mpix full color (R-G-G-B) pixels - not too bad for certain situations.

Just some ideas about a product that still doesn't exist on the market, will perhaps never exist and if, it is to expensive for me.

Just two additional decision factors:

(1) Do you have good chances to recharge your cameras batteries?
Yes: Model doesn't matter
No: 40D or 5Dc preferred above Rebel but only if you buy a NEW Canon Li ion battery for 2nd hand cams

(2) Do you have a chance to test some 2nd hand cams before your trip?
Yes: 40D, 5Dc possible
No: Better buy a new Rebel, but do not omit some checks to replace it eventually before the trip

My choice (= influenced by my photographic ideas) might result in the following sets:
(a) 40D + EF-S 2.8 60mm + EF 2.8 24mm (all 2nd hand) (250 + 250 + 150 EUR),
(b) 600D + EF 2.8 40mm + strong closeup lens  (450 + 150 EUR + 50 EUR) or
(c) 40D + EF 2.8 40mm + strong closeup lens +new original battery (250 + 150 EUR + 50 EUR + 90 EUR) or
(d) 40D + EF-S 2.8 60mm (new) + new original battery (250 + 350 EUR + 90 EUR).

Set (a) has a strong potential (38mm + 100mm Macro in 35mm equiv) but is heavy and you rely on the chance to get these things in technically mint condition for low prices.
Set (b) lacks the use of different focal lengths and pure macro but avoids changing lenses, is light and compact and I really like the IQ, photographic flexibility and compactness of my 40mm lens. With a close up lens it should bee good for closeup photography.
EDIT: Addet set (c) because this is my HQ compact camera and set (d) which I would choose just if just ONE camera and ONE lens for a trip is "allowed" - I personally like the 40D much more for photography than the 600D but this may be caused by habit ...

The most underrated, overlooked lens I have is the EF-S 60mm macro. It does everything from macro to landscapes and usually gives a unique look.
...
+1

If I had to do photography with an APS-C body and 1 single lens my EF-S 60 would be the one! It was my first lens with the 20D and the reason to switch from my G2 to the DSLR boat.

Canon General / Re: POLL: Satisfaction Level With Canon products.
« on: July 19, 2013, 03:39:41 AM »
I "love" my trusty 40Ds and the "medium class" lenses I have - well crafted, reliable: Tools!

with focal lengths from 16 ... 4000 mm with equipment which is accessible for mortals.

Are you using the video zoom?  If so, how does it hold up?  I've never tried it tbh.

I got camera wobble with a 600mm lens (100mm equiv) how does 4000mm cope!?

As example of a video still I can offer the following:
http://www.canonrumors.com/forum/index.php?topic=15877.msg291715#msg291715
(perhaps you have to scroll down to the photo of the moon)

Equipment:
600D + 3x Video Zoom (1920x1080, 24p) + 2x TC mk i + EF 5.6/400mm
(1.6 x 3 x 2) x 400 ~ (10) x 400 = 4000 (!)

I think the quality is more than acceptable and the non-uniform sharpness due to atmospheric effects shows that in vacuum the IQ still would be better - just I still prefer an earth WITH the current atmosphere ... ;)

Another example: the 70-200 4.0 mutates to a 110-320 + 330-920      @4.0 - VERY versatile. The 3x zoom function setting which uses a 1920x1080 region was the unique decision factor for the 600D and makes the 70D (has it too) a possible candidate to raeplace the 2 x 40D + 600D by 2 x 70D.
