EOS Bodies / Re: 70D and Dxomark....
« on: August 29, 2013, 08:46:35 AM »
I was already on FF when 7d came out but through the years i had a chance to review files from assistants, friends & gfs from either 7d 60d or d7000 (have to find one with a pentax now  ;D ).
The IQ difference isn't that tiny really. First you can get really nice files out of those sony sensors below 400. You can get FF quality easily, whereas 7d really has noise all over the spectrum.

I own a 7D and have shot tens of thousands of frames with it and made several hundred 16x20" prints. And you're wrong.
Perhaps you have lower standards or you just dont care, in my case i've always seen noise from that 18mp sensor even at base iso.

I've also in the past taken the time to put up 100% crop tests from FF and APS-C, Canon and Nikon bodies to see if FF or Nikon fanboys could reliably tell me which was which. They always fail, but it also always ends up a waste of my time since they continue to spout their nonsense no matter how many times they fail.
I bet you liked also that test between iphone & dslr.
Explain to me though, do you believe that in some cases with the right subject, under some circumstances, the output from any dslr might be indinstiguisable from another, or do you maintain that this is the case generally?
If its the 1st one then congratulations Captain Obvious you won the party hat, if its the 2nd then by all means, please do create a separate thread and post your thesis about how dslrs have the same output regardless brand or format, im sure it 'll be highly entertaining.

You can see a  quantitative difference with local adjustments of about 1-2 stops and what happens to color and noise.

Sure you can...when you turn off NR on one camera and not the other.
You got me there, silly me.

Obviously you can see a massive difference if you want to salvage shoots where flash or strobes didnt fire; basically those sony sensors are isoless, you could push an underexposed iso100 all the way to 3200 and there isnt much difference from a native 3200, plus the tonality will be actually greater.

Sure you can. You can also leave the lens cap on and get perfect images, or so a Nikon fan told me.
Yep sure you can and hyperboles wont help your case.

"ISOless"...priceless...thanks for the laugh.
Indeed isoless and no doubt, with the proper amount of ignorance, its laughable and "priceless". Take care.

I'm sure I'll get flamed for this and maybe I'm missing something here, but when I compare the D7100 to the 70D and 7D on the graphs there doesn't seem to be all that much difference.

I admit I'm not a dynamic range freak, and I'm more interested in ISO performance, but it doesn't seem like there is any real world difference between the Nikon and Canon sensors.

There's a small real world difference in terms of IQ when you have to dig really deep into the shadows. It's blown up into a huge difference by...

* Shooting a wall in the dark.
* Shoving the exposure slider to +5 EV.
* Turning off all NR on the Canon sample.

If you normally shoot this way, Nikon is your first choice.

From someone coming from compacts or cameraphones the difference is nonexistent but from someone who wants too squeeze every possible drop of quality from an apsc sensors, then you'll find canon isnt your best bet.

The supported lens box has some very disconcerting information.  I'm wondering about 3rd party lenses that should work but will be in contrast-detect just because they aren't "supported".  Also, what's the point of having this function work at f/11 if it doesn't work with teleconverters?  Who has a "supported" bare f/11 lens?

Perhaps 3rd party lenses wont have a problem after all, here is a preview of a 70d with a 18-35 sigma performing splendidly apparently:

Yes he may be right, that's why I asked him.  ::) ::) it would be nice to hear from him, if he has any support for his claim I'm sure he will reply.

But I hope it's based on something a lot more substantial than a press release from a strategy meeting.  ::)

Already 2 persons posted 2 different sources that validate his claim, a simple google search was all it took, what kind of "a lot more substantial proof" would be good enough?  ::)

........ Sonys sensor department is healthy, they earn money from the mobile sensors up to 24x36mm
that other departments such as television, consumer electronics, etc. are not going so well is another question ......

Do you have any justification for this statement? or is it just plucked from the depths of your mind?

They sell to everyone -including canon-, they're bound to be profitable.

"Sony, the third largest semiconductor firm in Japan, divides its semiconductor business into in-house use and outside sales. The fourth-quarter revenues from outside sales reached JPY90 billion, representing a sequential increase of 19%. The firm has reported revenue growth for two consecutive quarters and continues to stay in profit."

They can crank out rebel after rebel after rebel because for key components they're just drawing from their existing parts bin and forking software projects, with minor tweaks so development and QA efforts are minimal, and offer a huge return for minimal investment. For the XD line (and the XXD) it's a different matter, since those models usually get the sensors, software, and other bleeding-edge components first.  That's also why the xD and xxD models cost so much initially - the first unit to roll off the assembly line cost tens to hundreds of millions of dollars to product - the second about half as much, and so on until R&D is fully amortized, enabling Canon (and Nikon) to lower the price, as the sales morph from recovering losses to earning profits.  See: amortization.

You're either oversimplyfing or you dont know what you're talking about;
First off there aren't really any "bleeding edge components" in XD or XXD lines, at least not "edgier" than a touch screen or that 70d sensor etc, yes usually tech trickles down the line but given the yearly cycle of XXXD series its bound to introduce "edgy" stuff on its own.

second, this:

It's one thing to add a gimmicky articulated screen to a low-end camera body using screens from your parts bin and make a new plastic mold, and tweak sensor designs you borrowed from pro and semi-pro cameras and get the product out in a month or three, and quite another to develop a whole new hardware and software architecture (as well as a fab process, metal casting molds and precision machining tooling with a tolerance of a few microns for a mass-produced product) from the ground up.

I dont really know where to start with this one.., it contains some truth in that yes developing a whole new hardware and software architecture is more time consuming than incorporating an articulated screen but then again it never happens to develop a new hardware and software architecture for a product such as XD; there also tech tricles down from the FF models, and what new there is isnt enough to warrant the "whole new" title. Plus last i remember IM tooling is about the same as mag tooling plus its actually absurd claiming a tolerance of a few microns for a mass-produced product, where on earth you saw something on a dslr chassis requiring more than die casting tolerances for mag alloy?

yep sometimes it greys it out, try this, before going into apply image, get into the channels panel and pick the A channel(or any single channel) so its the only one visible.

edit: And yes, both methods are doing essentially the same thing, remove all info of the selected channel, you might want to duplicate your layer first!

from image menu > apply image > bg layer >channel A, set it to subtract (numbers in the side should be something like 2/128

Alternatively, just fill the A channel with 50% grey

Imagine having the functionality and image quality of a 5D mark III but with the size and weight of a compact point n shoot.

That might be true in the future  but I don't think mirrorless will replace our DSLR.    Can you imagine we (professional wedding.....etc photographers all carrying a tiny small camera for the photo shoot LOL.   

Being able to have a p&s with the capabilities of a mk3 is half the equation in many cases.
On a pro level, things like ergonomics matters alot, either device ergonomics like the grip and controls placement either system ergonomics (eg head-camera-hand-lens, imagine a 70-200 attached to an iphone and you trying to shoot a 5hr event)
Plus, by the time you could cram a mk3 into a p&s volume, imagine what you could have in a 5d volume  ;D

... if the 70d can perform anywhere near the 6d at high ISO's it'll be more than adequate...


Why not 2 stops better than the 6D? why limit ourselves when we delve into the realm of fantasy?  ::)

I think these are pretty exciting times for APSc folks and Sigma's lineup is just second to none in this category. If i was still shooting APS -regardless of brand- i would be really happy with pieces like the 8-16, 17-50, 50-150 & 120-300 or the prime-pack 18-35/1.8. I've seen first hand what 8-16 & 17-50 can deliver and the reviews of 50-150 & 18-35 are mostly praises.

FF is another story and apart from primes sigma has still a way to go. Tamron on the other hand seems to be doing quite well with their 24-70, 70-200 kits.

All in all I'm really happy that the 3rd party manufacturers are breaking away from the 'affordable alternative' realm and into the serious contender territory.

Must be that new 'upmarket' body finish of the t5i  ;D

I like the front page but the idea is almost the same as tumblr's dashboard. I dont get how are they going to differentiate the 2 products
