EOS Bodies - For Stills / Re: Upgrade from 6D from 450D
« on: December 29, 2012, 02:53:13 AM »
What about a second hand 2.8 / 24 non-IS? ... if you do not need the f/1.8

Here a comparison of both lenses at f/2.8 on the digital picture:
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=246&Camera=453&Sample=0&FLI=0&API=0&LensComp=253&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=2

This lens is sharp, very contrasty, has fast (conventional) AF, is very compact and equals the 15mm in terms of APS-C. The new version of this lens might help to put some of these underestimated lenses on the used gear market.

WARNING: I have used the lens exclusively on APS-C cameras! The full time manual of modern USM lenses has its advantages!

After my experiences with my 600D the full HD resolution gives results which are technically far above movies made with Super 35 cameras. Viewing the smaller HD movies on an XGA beamer (1024 pixel horizontally) gives crisp quality at 2.5m projection width and 5 meters viewing distance. 4k Beamers are far away and just GOOD HD beamers are in the 5k€ region. So full HD in GOOD QUALITY will be sufficient for nearly all applications where the movie will tell us a story.

4k IMO is a new idea to make things incompatible and to sell new gear and to make things more complicated - with some exceptions.

You think 4K is just to make things incompatible and sell more gear?  What about megapixels on cameras then?  Is that all a big scam too?  Did you think the same when it went from SD to 720p?  Or 720p to 1080p?  4K has alot of advantages and is the future, it's just following a natural progression of things getting better like any other product.

And while the 600D may be fine for you, there are plenty of people that want something more.  Canon DSLR's aren't even doing real 1080p, there is plenty of room for improvement.

1080p is IMO sufficient for 99% of all applications and if 1080p beamers in GOOD quality are roughly 1000 EUR/$ we will wait another 10 years.

The way from SD via 720p to 1080p made sense: Image width: 4m, viewing distance: 5m, pixel size: 2mm x 2mm - that makes sense because the eyes resolution is in that region.

You are right that 1080p misses 1080 real lines. IMO it would be a better route to get REAL 1080p before you increase the sheer number of pixels without transporting more information. Nothing against 4k but it should not be the next step before 1080p is ripe.

Resolution for photography is a different thing because a landscape photo is browsed by our eyes for a longer time, resolution is important - in movies the camera operator does that for you.

But the 18 MP of the 600D do roughly compare with the 10 MP of the 40D: Limitations of the lenses and especially sensor noise cancel the advantage of 80 % more pixels a little bit. Except in situations where you have perfect light, perfect subject and perfect aperture values.

My first thought: Why just another SLR like camera for video - Canon is making its camera family more and more complex.

But: Why not? Each artist (or gear buyer...) has its own ideas about their "product" - photographs or movies. Canon does NOT mainstream their product portfolio but offer a vast range of different tools.

If I decide to go more into video (after having time to try it, a new PC) it might be a good idea to have a video capable camera which produces GREAT HD videos (with per pixel sharpness) and has good controls for aperture, shutter speed, iso etc.

After my experiences with my 600D the full HD resolution gives results which are technically far above movies made with Super 35 cameras. Viewing the smaller HD movies on an XGA beamer (1024 pixel horizontally) gives crisp quality at 2.5m projection width and 5 meters viewing distance. 4k Beamers are far away and just GOOD HD beamers are in the 5k€ region. So full HD in GOOD QUALITY will be sufficient for nearly all applications where the movie will tell us a story.

4k IMO is a new idea to make things incompatible and to sell new gear and to make things more complicated - with some exceptions. 7 years ago I searched for a large chip (Super 35mm) video camera with exchangeable optics - I had to spend roughly 100000€. I decided to wait a little bit and bought a house instead. The 500€ T3i (600D) does everything what I needed ... what a sense of freedom in terms of "you can buy valuable tools with a standard income".

EOS Bodies / Re: Canon T4i or wait for T5i?
« on: December 27, 2012, 08:59:26 AM »
I had to choose between T3i and T4i/Eos M and decideded for a T3i (600D) because:
 - IQ of T3i seems to be little bit better than T4i (perhaps just variations between samples, but T4i hasn't the potential to be better in IQ)
 - I am trying to do some video work and therefore I need very long focal lengths in the region of 2000mm. T3i delivers a video zoom mode where it uses the centrally located 1920x1080 pixel area of the sensor - a 3x TC built in! (5.6 400 mutates to 5.6 1920 equivalent meaning to acquire the full moon in reasonable HD quality!)

For taking photographs I like my 40D bodies which deliver nearly the same overall quality despite of only 10 MPix.

Software & Accessories / Re: DPP Digital Photo Professional
« on: December 27, 2012, 04:31:00 AM »
I am shure you have checked most of these settings, but just as a hint (from a PC user who uses running systems for 3 or 5 years to avoid such hassles!)

- do you have used the same RAW files and the same DPP version on both machines? Between 40D and 600D there is a factor 4 or 5 in processing speed on my old 3GHz P-IV Desktop

- how many cores do both notebooks have? What is the max CPU clock (not the only criterion but you have two systems with similar CPU architecture, so it should scale)? As far as I know DPP is multithreaded, meaning that it can use all the cores of your system and it profits from CPU speed too.

- does the graphics card use hardware acceleration etc.?

- check the energy saving settings of the notebooks: Set it to maximum performance at least if it is connected to a power plug

- check for "parasitary" software (as John stated) like virus scanners or recovery software

pre 1982: simple cassette camera 24x24mm (Agfa?)+ Bali automatic 35mm viewfinder camera, Agfa Box
1982 AE1, stolen in 1984
1986 2x EF       (great camera, liked the concept of having two bodies with e.g. 50mm macro and 200mm tele)
1987 Rolleicord Vb
1995 New F1    (never really used due to stress during phd and the aftermath)
2001 G2           (re-entry to photography, digital world helped me to get feedback soon)
2005 20D         (with EF-S 60mm - the reason to switch to DSLR after experiments with G2 and diff. lenses)
2009 2x 40D     (still like the concept of having two cams with two lenses 10-22 + 70-200 or 40 + 100 macro ...)
2010 S95         (work horse for allday use in school (as teacher))
2012 600D       (for video, 40D always preferred for photography due to ergonomics and quality)
2014 2x 6D???    (will still like the concept of two bodies, but ... really expensive then)

Hoping to reuse some of the old FD lenses with a FF mirrorless camera (3.5 50mm macro, 2.5 135mm, 4.0 17mm, 1.4 50mm - nothing exeptional, but perhaps some interesting characteristics)

Lenses / Re: Canon EF 50 f/1.4 IS in 2013 [CR2]
« on: December 13, 2012, 08:29:33 AM »
This lens has the potential to be a killer lens:
- reasonable high max aperture
- IS to extend shooting ability in sparse light
- chance to get wider DOF by using the IS and a smaller aperture
- chance to deliver much higher contrast @f/1.4 as the current version by use of special glasses or/and aspherical lens(es)

Hopefully it gets a good minimum focus distance of about 30mm 30cm (is sufficient) - very helpful to stretch its applications as universal standard lens (on FF) or light telephoto (on APS-C).

If it costs 800€/$ and delivers perfect qualitiy (contrast, flare resistance, texture fidelity, bokeh, low distortions & vignetting) it will be a very well priced lens.

Canon General / Re: Recommended photography books
« on: December 07, 2012, 02:08:16 PM »
I like Bruce Barnbaum: The Art of Photography - he tells a lot of technique, but technique is for him a precursor for the  expression of your vision of a photograph. Nothing less, nothing more.

It helped me to get focused on the photograph itself and reconditioned me to use cameras just as a tool which is without any value by itself.

(And a good opportunity to refresh my english knowledge by reading the original version!)

EOS Bodies / Re: Why do you want a FF Mirrorless?
« on: November 22, 2012, 02:24:48 PM »
[...]
Wide angle lenses will be inferior (You can't bend light that much without many lens elements).
[...]

After my information it should be much easier to produce a high IQ wideangle if you are not restricted to place the last lens element before the maximum protrusion by the mirror of an SLR.

SLR wide angles are always retrofocus constructions which shift lens planes behind the physical lenses- to keep the mirror space clear. Why have 85mm lenses and focal lengths above such extraordinary IQ from center to corner (o.k. in most cases)? They are not retrofocus so you don't have to struggle with extreme lens materials or lens geometries.

EOS Bodies / Re: Why do you want a FF Mirrorless?
« on: November 22, 2012, 08:46:03 AM »
I am really interested in a moderately priced and compact FF mirrorless with a large capacity battery (750+ exposures per charge). OVF should be optional to keep footprint small.

Please use a shorter flange distance but EF mount with sth. like a 20mm extension tube as adapter for EF lenses - which can be used for other purposes.

Please give us an aperture ring around the mount base.

Please give us a status display showing f, t, ISO, charge, free data space, format, drive mode, exp. meter characteristics, color temp. and exp. compensation PERMANENTLY (e-ink display?).

Don't make it a luxory article but a simple but tough and reliable tool. Without mirrorbox etc. it should be easy to build such a camera for roughly 1200 $ / €.

Lenses / Re: 24-70 F/4L IS - Why I will Buy/Not Buy this lens.
« on: November 18, 2012, 05:45:37 AM »
If IQ is brilliant, it would be a candidate for buying.

The EF 18-55 is an awful lens in terms of haptics - optically it is o.k.
I tend to see 70mm as a useful standard focal length, I love the 40mm
on APS-C bodies which equals to 64 in terms of 35mm equiv.

The 24-70 4.0 is light weight and might be my first IS equipped
lens. Additionally it bears a very interesting macro mode.
On APS-C: a 38-110mm equiv range is very versatile FOR ME
and on FF (if I change to that format) it is a good general purpose
lens.
If I go full frame it might replace the EF-S 10-22, the EF 2.8 24, the
EF-S macro and the EF-S 18-55 and makes choosing a lens set
much easier.

Combined with the 2.0 100 it will be a fine two piece set of lenses
delivering high apertures where it counts: on the tele range.

Lenses / Re: Kit for travelling around the world for 2 years!
« on: November 17, 2012, 05:45:40 AM »
My 2 ct:

It is nice to have a backup body "on-board" and a secondary body minimizes
lens changes dramatically.

Existing:
   5d mkiii          +             24-105
Add:
   7D with 70-200 mkii:   2.8 110-310mm   + close up lens (+ TC 2x for "long range")
   40mm 2.8

might  be a good combination to have 24mm .... 310mm effective focal range
without the need to change lenses too often.
If you don't need a dedicated macro lens a "stronger" close up lens (achromatic
correction) will give you perhaps enough close up range and quality without
a lens change.

The 40mm 2.8 on a 7D (60D, 40D, 5D ...) is very light and unobtrusive. It can be
worn near the body to keep the camera (battery) warm and to be less visible
- a very valuable lens with very high IQ, just in contralight!

Good luck for your trip - an amazing project!

Best - Michael

Video & Movie / Re: Yamaha R1 Video Clip - shot on a 7D
« on: November 15, 2012, 02:48:40 AM »
Well photographed, your movie has something like a rythm which is well synchronized with the sound and gives it incedible dynamics!

Especially I like the effect of a B/W subject surrounded by color which is still THE main subject ...

Cool! Best - Michael

Lenses / Re: A EF to EF-M TSE Adapter
« on: November 11, 2012, 04:12:39 AM »
I was thinking there is enough room there to make an adapter from EF to EF-M mount that incorporates tilt shift functionality especially if it had AF pass through, might be another cool piece of kit edmika could build :)
being able to use say a tokina 11-16 f2.8 with tilt shift functionality would be pretty cool on an EOS-M

That's a really cool idea - the only drawback is that the image circle of FF lenses allows just a moderate shift displacement while staying in a good quality area of the lens. BUT: stopped down the 11-16 from tokina is useable for FF and a stopped down 2.8 24mm might be fine for larger shifts ...

But tilt? Great for macro, landscape, etc. ... and then the lens doesn't need a much larger image circle than APS-C for an APS-C sensor.

Or think about a deluxe lens baby like adaptor with three screws and a bellow and a fixed "normal" position ... infinite creativity which should be done for - let's say - 100$/EUR ...

@dr croubie: If you give the wires more room (helix) and if you use high quality material (5$ instead of 10ct) wires are o.k. ... or use a bluetooth connection between body mount and lens mount ;)

EOS Bodies - For Stills / Re: Convince me to shoot in RAW
« on: November 10, 2012, 01:53:37 PM »
In data acquisition I have one rule: NEVER ever throw away the original data.

RAW is original data with the full information of what the camera (sensor + lens) are capable to record.

1. More DR (at lower ISOs, depending on camera) so you are free to change contrast, black-point/white-point, color curves, color temperature without loss or with very little loss.
2. Think about the invention of a new algorithm to convert RAW files into other formats like JPEG with enhanced quality - with JPEGs only you loose.

That's why I love my 40D much over the 600D: clean 10MPix raws with reasonable size instead of 18MPix raws with 1.5 times the size but not substantially more information.
