EOS Bodies / Re: AE-1 Styled DSLR from Canon?
« on: Today at 05:03:30 PM »
IMHO Canon will not consider making a 'retro' look dslr because they haven't fouled up the design of the current EOS. It has been a gradual evolution in staying up to date, a little like the Porche 911 perhaps.

The latest Nikon's on the other hand looked like they were designed by Dr. Jekyll after a night out on the town as Mr Hyde, so I can quite understand Mr Mitsubishi saying 'let's get back to what we were good at'. Except they then seem to have let Quasimodo's great aunt design the Df.

One day soon Mr Mitsubishi is going to find out where Canon's chief EOS designer goes out for his drinks, meet him there and press a great wad of Yens into his hand and say: please come and work for me.

I'm holding out for the 85mm f/1.0 L, myself.  More light, not less.  IMO, the notion that sensor improvements negate the value of fast lenses is just silly.  Sensor improvements make fast lenses more capable.  :)

Well they do and they don't. Research it and I think you'll find there is a fair bit of jiggery pokery going on to get an f1.2 lens to record like an f1.2 lens.

However I think it's fair to say the modern AF does make a very fast lens make more versatile sense.

Not sure what impact this will have on EXMOOR availability in the future.

http://www.bbc.co.uk/news/business-29233644

Exmoor is where they have lots of deer and heather  ;)

In your link I didn't see any analysts saying " Exmor will save Sony stock !"

Or even Exmor anything.........

LOL at the trolling regarding the 7D2 AF, first of all the guy was making an informal test of the High ISO SOOC JPEGs from the cam, not its AF performance.

Yes, an informal test, so the results of it should be universally ignored or taken with a grain of salt.

at least he has his gut to post his out of focus image?

What he did wasn't gutsy but a plain grab for attention and clicks.

how about you?

"mine is bigger than yours"? How mature.

1. bigger but useless does not help  :o... LOL...
2. he is a business guy, what do you expect...

however, i have at least realized that you know very little about how to take images... otherwise, you already take my challenges...  if your images are that s*cks, then do not give out comments or try to educate other people about photography after doing some crap research around the internet.  if you are that good in technology, then apply for the r&d departments...  instead of being so, join forums and keep learning just like some others and i do...

you have not answer my previous question on topic "Do Sensors Make the Camera" and again, be-careful in giving out answer, otherwise, i am going to call you as a guy being born with tofu brain...

... or you want to downgrade to my canon 30d and 50mm f/1.4?  again, i guarantee that your images cannot be sharper than mine regardless what camera i use (from canon 30d to modern), certainly not better than any others in this forums, but definitely better than yours...

note:  my daughter at a chess tournament, while little one playing crazy chess with her friend...  taken with canon 30d and 430ex ii (in single shot mode, not high-speed burst since i hate process of rating images).  if admin think what i am talking is not right, let me know and i will delete my post immediately...

Your first two pictures are excellent and proof that we've been able to make great digital images since the early naughtiest. Having said that the 30D was never the best landscape camera and incritical observation produced pretty noisy skies, although to be fair this couldn't be seen in a practical print unless very big.

With regard to the high ISO examples shot by this guy at photokina I'm sure his emphasis was an grabbing some high ISO shots, and let's face it; they are remarkably good, and I'll be fascinated to see some critical low ISO shots too.

Regarding the focus - OK so the camera technology probably isn't yet dilbert proof, but which is ?

:'( I think something is up with my 5D III.

Seems everyone is aware of that, you have so much trouble with noise an all.

While some people are complaining as you describe, other continue saying "How could they put the same sensor? >:( ", which is kind of pathetic. However, lets forget those people and focus on the possibilities of the all-new 7D MKII sensor!!  ;D

Indeed.  But let us not forget the all new 18 MP APS-C sensor in the T4i/650D (all new because of Hybrid CMOS AF) or the all new 18 MP APS-C sensor in the SL1/100D (all new because of Hybrid CMOS AF II).

 :-X

Good point. But given that there is no new technology advertised (that I can see, that is), is it fair to assume the "newness" will come from the actual sensor? I sure hope so. :-\

Perhaps.  Canon had a patent publish recently on improved DPAF for use in AI Servo AF, and now the 7DII has DPAF in AI Servo AF.  I'm not sure if that required a hardware tweak to the sensor, but if so, that could be what's 'all new'.

According to Dave Perry of Canon UK in the YouTube video link posted in this thread, the 'all new sensor, different to the 70D ' is............micro lenses.

Here's the link again for anyone interested.

Just had a quick read through the DPR of the camera; it looks like one hell of a beast for the money. So it has come in under the RRP of the 6D as I thought it would, and this suggests to me that Canon are pretty confident in their FF premium on price.

Also interesting that DPR refer to the Dual pixel technology as effectively 40 mp........I seem to recall someone here on CR vehemently disputing this.

Canon's priority is DR at the top of the histogram (where it performs very well), and that suits me just fine.
You completely misunderstand dynamic range.

Is this what they call "field day" in English :-> ?

'Having a field day', yes, except everyone with the exception of jrista would have interpreted Keith Reeder's statement as 'photographic latitude at the top end of the dynamic range', and he is absolutely right. Look at his examples:

I still find it laughable though that in the end, it really really, really, does seem like people are all too happy for Canon to not get their DR up to where the competition is

Which assumes, of course, that - unlike an old, out-of-date, underpowered PC - this supposed lack of DR actually stops us from getting the results we want.

Which it doesn't...

Canon's priority is DR at the top of the histogram (where it performs very well), and that suits me just fine.

Let me know when a Nikony sensor can do better than this from this, and you might have a point...

If you want to maximise the latitude from the Canon sensor you must establish how far you can push the 'over exposure', and it is often quite a long way.

If you go back to dilbert's example, in much of the picture the sensor was recording virtually no information. Try and lift this and surprise surprise, you are going to get a poor result.

Canon will do what it believes is in the best interests of its shareholders in the mid to long term, coincidentally they very often know better than us what we actually need.

Having moved to Canon after many years with Nikon I think there is a great deal of truth this statement

Third Party Manufacturers / Re: Nikon announced D750
« on: September 14, 2014, 04:28:48 AM »
..Let's think for a second: who will buy the D610 if they can pay a few hundred more for a D750?
I am more envious of the 20/1.8. I wish Canon made something like that...


As for the 20/1.8... I'm salivating just thinking about it.
I use an old AIS MF 20/2.8 and an AI 20/3.5 and they're both very good, the 3.5 being very compact and light.
it there's slightly better corner sharpness with lower CA in this new lens, it will be very welcome

I'll be interested to see if this lens is anything other than a blurry mess at 1.8, and how deep an aperture it takes to sharpen up the mid frame.

I'm unclear on the real application of these very fast ultra wides. I can appreciate that at f2.8 they have much less vignetting than a f2.8 lens yet they are inevitably worse across the frame in resolution.

An ultra wide that is very good at 2.8 would be interesting because of the high dof produced by that focal length at that aperture.

I'll be interested to see if Nikon have been able to do this but I doubt it.

I hope for the sake of those potential 7DII users the rear wheel doesn't feel like the 6D. I see it now has some four way function set inside it, it looks very much like the 6D outer wheel, but hopefully it won't feel like it to use.

I did bracket it. At +1 EV the highlights are unrecoverable.

Usually you can recover ~1ev from the raw files, so imho your bracketing spacing is too small and only will create problems when assembling more shots than necessary.

The snow is *really* bright and the shadows in the tree quite dark.

To be on topic concerning the 7d2: Rejoice, in such scenes, no sensor dynamic range upgrade will be enough. Snow is very tough, a good choice is to bracket with a very large spacing (like 3ev) and then do not hdr tone mapping, but exposure fusion in postprocessing as the scene consists of very dark and very bright. To minimize wasted exposures, do exposure correction to get the correct brackets.

Where higher dynamic range of 14-15ev does help a lot though is in standard bright daylight to get shadow detail w/o blowing the sky. You can use Magic Lantern's raw histogram to show you exactly how much dr the scene has.

This is the point. You have to know when to let white be white.

Let's say that had been shot in exactly the same way on a D800. Probably about 85% of the scene is in heavy shadow opposed to the tiny amount of direct sun reflecting snow. Dilbert does exactly the same thing and lifts the majority of the scene. It's Exmor so he retains more detail and less noise. He's happy.

However, the majority of his picture will have been produced from under severely exposed data. When compared with someone using a superior technique / process, his image will be inferior even if that someone is using old tech such as  20D, or D70 or whatever.

You have under exposed for this scene. Pic 0 histogram shows this, pic 2 shows that you have too much highlight detail after bringing in down 100.

Did you bracket for such a scene of difficult EV range ? If you had a 2/3 or 1 stop over exp you would be able to work the data much better.

At least you are trying with examples. Don't be frightened to go a little to the right, learn to judge when the LCD 'blinkies' are just joking. If you are working from the rear LCD picture set your picture style to 'neutral' and contrast '0' when shooting a scene like this so you will have a better visual of what the raw will able to cope with. Don't be afraid to bracket.
