Software & Accessories / Re: Adobe Lightroom 5.7 Now Available
« on: November 20, 2014, 03:29:25 PM »
I hope they fixed all performance issues they introduced in 5.6 for spot removal and selective brush.

1/ Those issues date quite back before that.

2/ Dream on. I doubt that they would be able to fix those with LR 6 possibly  (coming out final release in March 2015).

They have big issues performance wise, because they have written it in LUA and since then (according to wikipedia) 40% are still using it. They also use SLQlite in the backbone of the catalogue. In the beginning perhaps it was the perfect combination, but with time and all those cool features added things begin to get ugly.

It's time to completely re-write in a more suitable

An F 2.8 lens is a 2.8 lens regardless of the sensor size, the amount of light it lets in doesn't change by changing the size of the sensor. This camera is equivalent to 24-200mm in 35mm terms and the only thing that is different is the depth of field.

Oh, just the DoF is different?  Well, that's ok then...I mean, it's not like DoF matters for pictures, or like photographers care about DoF or anything like that, right??  It's a smaller sensor, so is noise or anything like that different?  Or is that something else that doesn't matter?

If you say 8.8-73.3mm f/2.8, that's fine.  Saying it gives a field of view equivalent to 24-200mm on FF/35mm is fine.   Calling it 24-200mm f/2.8 is a lie, since f/number is focal length / iris diaphragm diameter.  Calling it equivalent to 24-200mm f/2.8 on FF/35mm is also a lie, the DoF for equivalent framing is different, which means they can't be equivalent.  It might be done commonly, but it's still a lie.  People exceed the posted speed limit all the time, it doesn't mean they're not breaking the law.

You couldn't hold it now, could you? :-)

Alas I saw it too late :-(

- 64-bit processing picture (much higher performance that anything Canon has today)

Could you please elaborate on this....
The raw computing power of the hardware is higher (A8 processor vs Dual Digic 6)(I am comparing iPhone 6 to 7D Mk II). Apple are doing some things with images they don´t say but some things are official:
- Tone matching flash
- HDR photo
- HDR video
- Slo-mo video (120 fps or 240 fps)
- Time-lapse video
- Cinematic video stabilization
- Continuous autofocus video
- Take still photos while recording video
Some things are more speculative:
- Picture stabilization using motion coprocessor together with gyros and accelerometers
- Near realtime composites of 4 separate photos to decrease noise and increase sharpness

I would argue that the A8 is a better platform for further improvements in picture processing and it is easier for Apple to propagate these improvements with the normal system upgrades.

Added to that is the immense number of post editing software that runs on the phone...not much of that on Canon...

I tend to agree with your idea. However please note:

1/ 64 bit has nothing to do with that.
2/ 2 CPUs on the CANON are for one sole purpose: more fps.

Otherwise most people here and elsewhere will tell you that Smartphone shooting is a lame (not even amateur-level).

I on the other hand have a different more like your idea about those tiny little miracles.

Smartphones as they may (still) be in their infancy. I see a great new expression tool.

Soon the difference between Smartphones' BSI CMOS based cameras would be as different as the Full Frame to the Medium Format - almost unnoticeable for the regular human eye.

Will see ;-)

I’m not sure I agree with them as far as the Sony A77 II being a more compelling option, especially when you consider lenses and other accessories

Well, actually they are evaluating the camera and not the complete set, you know! ;-)
This last sentence was really not very in favour of Canon.

I think that this rumor is way to unclear for a CR2 level.

EOS Bodies / Re: Modular DSLR Coming from Canon? [CR2]
« on: October 29, 2014, 12:14:41 PM »
Wow a CR2 sounds quite interesting in the sea of CR1 speculations..

What else could be modular?...
  • Lens mount
  • Sensor
  • Storage options (SSD?)
  • Camera body mount
  • Communication
  • Power options
  • Processor(s)
  • Auto focus system

These few sounds quite nice as options to me. I don't mind Canon leaving the marketing segmentation up to the customer. Especially when we are talking about Pro Level equipment. One can buy what one needs and is important in his area of shooting.

However again they seem to be trend followers. Modular cameras are existing for quite some time. In their endeavor to conquer Hollywood they are a little late. Hollywood is not what it was 25 years ago during the VHS era.

A modular DSLR on the other hand would be perfect. However in times of migrating to both Mirrorless and Medium Format unfortunately it might not bring a lot of sense as well. :-(

EOS Bodies / Re: 4K Products Coming From Canon [CR2]

I am not sure why there are so many freak outs and threats about switching to another brand.
When canon releases them they will be a solid reliable product. THey may not have the most cutting edge features(that seems to be Canon of the past) but they will be reliable, solid, functional. Thats what i want out of a product i am using to make money.
If i have constant camera errors i become and unreliable person to use no matter how good i could be.

I do my living with that too and honestly I have NO idea what-so-ever what PRO brand have you used before Canon. But I know the following for me:

I am in a need of upgrade. At the moment dollar-per-feature is not good enough with Canon for my needs. Even now as rumors I might get a new sensor offer and a video servo focus (that I don't need that much). A better ISO (probably - having in mind the stupid 4 year cycle of their sensor generations) an incremental increase is to be expected. 4k - hopefully and it is really pain in the ass to have to wait for every one competitor out there in the pro market to be before your own choosing of brand.

Now my competitors on the market can offer better service, because they use different brand. This of course leaves me without the option to stay topcat in my field.

And slowly I have to begin to miss my lead and stay behind and that is about image and name... For the moment I am the only to realize that. In beginning of next year I might jump ships because my competitors might find out as well.

My creativity suffers as well. I know that there are features I can test out... but will have to wait. And no - I won't rent - because these are tests of well known features that will soon or later be mine as well and I don't make money out of tests!

Just like this was the year of the lens? I'm no conspiracy theorist, but maybe spreading rumors is official Canon policy right now for trying to stop video guys from jumping ship.
yes of course it was: CZ and Sigma got great lenses for Canon out :))))


Read into things much? The examples were chosen *because* most people have opinions on the subjects. voted for Obama, love hip hop and celebrate popular youth fashion?  You'll forgive me for assuming that someone posting these things on a forum that skews heavily toward wealthy, middle-aged/elderly American and European white men had a specific opinion in mind.

You are right that ignorance doesn't stop people from forming opinions but it really really should.

This will be my last on the subject, ...continue if you please.

I am "the decider" re. whom/what I  will forgive  ;)

In this case I will base the forgiveness on your obvious lack of situational awareness. You really, really should note that your ignorance re. my voting/music/fashion preferences has not "stopped" you from forming an assumptive opinion about same. ( FYI, your score was 33 1/3%, my experience, this is a failing grade. )   :o
At least we now know who you voted for ROFL

I'd jump to buy a camera that had a max ISO of 100 and 1 fp 10 seconds if it offered better resolution and DR.

Get a 7D Mark II and a Gigapan.  In 10 seconds, you can shoot something like a 9 shot panorama with a 5-shot bracket at each spot.  That should get you 16+stops of DR and 115 megapixels.
I would go with the 6D instead ;-)

You guys completely misinterpret and misrepresent everything I've said about this subject. You lump me in with your run of the mill complainer who jumps from site to site bitching about anything and everything Canon. I've been very consistent in my complaint...and it's just one complaint: Canon's sensor IQ, particularly the quality of their read noise, but their overall IQ that, IMO, suffers because of poor DR which stems from extremely old (ancient, in the tech world) technology. Stop misrepresenting me and my words to the rest of the community.

Jrista, it's the avatar. ;-)

You are a run of the mill complainer, you want something that isn't available in Canon's range, and you want them to make it for you.
IMO he is making an informed complaining. That means he's quite well aware what the others are doing or intend to do in the near future. He is informed about trends, brands and and all sort of tech stuff. So is Neuro. Both create opinions and seem to be among the most acknowledged in this community.

That doesn't mean we shouldn't argue with them. But at least make a point out of it. ;-)

Not the patent, not sure where that is. Here is a paper on the topic, though:

Mostly by Aptina engineers.
Nice one, but main goal should be to get all the 32 bit of information and not some discrete auto HDR image.

I love to walk around with a brush or any other PS tool in order to get what I want.

Yeah, I'm bummed the domain expired. Those guys do seem to update the site with recent cameras...maybe it will come back when they notice the domain expired.
I will try to ask around about it :-(

Regarding the whole stacking/in-sensor HDR idea. Other companies are working on that. There are patents that support just that very thing. Some companies are even researching how to use dual-gain (basically the same thing as Magic Lantern's Dual ISO) to improve dynamic range WELL beyond 14 stops (20, 22 stops maybe more).
You sure about it? However a simple stacking of 3/5/9 frames @ different stops embedded in on image @32 bit is the best even without the multibucketing. The latter could only be useful for sport & High-FPS photography.

However if you have some time could I kindly ask for a patent or two links - it would be certainly of high interest to me and you definitely read patents better than me.  :-[

This is why I'm frustrated with Canon, and now open to alternative brands. Canon, while a highly innovative company, doesn't seem to be all that innovative when it comes to sensors. (Which is REALLY weird to me...given that they are an imaging company...pretty much everything they do revolves around digital image sensor technology.) Canon just doesn't seem to be in the sensor innovation game right now. They have had a couple, but none of it (at least so far...maybe their layered sensors will change things) has been very ground breaking. DPAF is pretty awesome for video...but even that was an evolution on an idea Fuji originally implemented (and I think Fuji got it from a much older paper.)

Yeah! Tell me about it.

At least for one thing that Neuro imposter IMO was right:

"the real problems are the managers at canon
they are lazy and have made their fortune.
hell is there even one under 60?

Or Canon was more conservative on R&D spending (which I believe is not the case since if I recall correctly they have kept investing about 2% of their profit).

Back to the HDR sensor topic. I think the most viable technology at the moment is multi-bucket CCD-backed pixels. This is an Aptina innovation...they took the basic single-CCD backing buffer or "memory" for global shutter, and expanded it to four CCDs per pixel (it's a CCD, or charge-coupled device, as that's a very simple and efficient way to move charge from one place to another). With four memories per pixel, the charge in the pixel can be moved to memory four times.
Patent link, patent link PLZZZzzzzz

As for the global shutter - don't even remind me about that. Everybody is slowly getting on that ship too. If I remember correctly Canon has no such feature in any of its CMOS sensor within any Pro level camera.

And that is a good trend to follow at least.

I say they separate again the 1D series or they might actually separate the 5D series perhaps.

* - 1 for sport (regular updated CMOS BSI tech)
* - 1 for studio (new FOVEON slower but better than Sigma sensor)

Additionally the speculation of mirrorless and DSLR also seems quite reasonable along with the astro version.

I love colour, don't I?  ;D
