Lenses / Re: 85L or 135L?
« on: September 09, 2013, 12:15:48 PM »
The 85L has a ... 1 stop advantage for moving objects.

Sure...if the ponderous AF of the 85L can keep up with the movement.  :P

Well, it is not a sports lens. I meant - people in general.

If kids are also people - in general, it could be more demanding than sports

EOS Bodies - For Stills / Re: RAW or JPEG

100% RAW + 100% JPEG
If only one option, 100% RAW

Sharpness wise the Canon looks like a hazy blurry mess at f/1.4, the Sigma is much clearer.

The difference between f/1.2 and f/1.4 is almost non-existant. Due to the way that digital sensors are designed and different from film - a digital sensor actually exponentially ignores light that hits the sensor at higher and higher angles of incident
So here's the difference between the magical bokeh of the f/1.2 and the Sigma:





I'm an extremely picky photographer which is why I obsessively test every lens.

It is amazing how biased some people can be. They can go to the extent of falsifying data... although not a smart attempt. The image examples you show are of Canon vs Canon at f1.2 vs f1.4
Infact, your file links for images shows this correct info.
If you show correct examples like here:

http://www.the-digital-picture.com/Comparisons/Sigma-85mm-f-1.4-EX-DG-HSM-Lens-Aperture.aspx

You will see that bokeh of Canon f1.2 is way better than Sigma f/1.4

But with the intensity of your rabid defense of Sigma f/1.4 on display; it might likely prevent you from seeing any difference  :D
On the record, I like third party underdogs as it fosters innovation and forces giants to keep prices sane.
However don't try to discredit a better lens just because you bought a cheaper one. And I am not arguing whether its better worth the double price tag. It's up to buyer to decide that.
And don't try to drag me into arguments; only reason I replied was to point out that you falsified your examples...

Short answer: switch it off
For those still persistent about fixing it post by software, pls read the posts by Pi and emag again. While you don't need this feature except for certain long exposures, you cant FIX those one in post unless you have captured dark (= no light to sensor) images with identical exposure conditions (read emag). And I agree with emag that collecting dark images yourself gives you more flexibility in treating the noise.  Its like you can't do HDR post unless you have collected images with varying exposures and collecting images yourself is better than in-camera HDR. Just to add for people who are not trying to understand before shooting a reply; there are still thesis being written for finding most efficient way of background subtraction (which includes dark current/read noise) because its very critical to quantitative imaging.

I am for freedom of expression  (of course, bullying and abuse should not be tolerated). I avoid reading most rabid and useless posts so can't say if  this person did that. If this person is banned just for being persistent opinionated PITA$$, then ignoring his posts is a better solution.  You can't clap with one hand. So someone else also has to be responsible here. Also, I don't think usefulness should be criterion for being on forums.  This is not some kind of classroom where every discussion have to be useful. Regardless, most discussions on all forums have always been pointless or tend to become pointless. And I don't see anything wrong with that. Its fun to watch posts like 'I bought camera XXX and its much better than 1DX' or 'my camera sucks, why cant it have all the features of 1DX at $700 price tag'.
Once in a while I do get useful information and tips for good deals. That's pretty much what blogging is about everywhere. I have people reply to me in an insulting way here, I just don't reply back. If I see a thread is pointless and is not even fun, I don't even read it. 


A practical suggestion to moderators to avoid trolls taking over: Make a separate category for opinions out of gear talk and keep it at the bottom of page. Keep and enforce the gear talk specifically for advice/discussion on practical and useable functions of gear (like menu, buttons, uses, tips, tricks etc). Move all the abstract and hypothetical B%&%@*% aka opinions ('like zooms are better than prime' or vice-verse, 'EOS M is the best camera ever', 'why is 35/50 mm a standard FL, why not 30/40' etc.) to 'gear opinion' category and don't show opinion category posts on forum discussion list on home page. This could be the best of both......

This is just my opinion.
In the end, the people running the show/forum have (should have) right to decide what kind of platform they want to provide. If you don,t like it........

EOS-M / Re: Mount EF, EF-S or L lens on EOS-M --- Your thought???
« on: August 27, 2013, 03:24:27 PM »
Don't expect everyone on dance floor to stop, so you can get focus. About the groom and bride walking the aisle? About bride throwing bouquet? You think the M focus is fast enough for those moments?
Once upon a time, I managed to get moving atheletes in focus with a Minolta X-700.  Now, if you mean you wouldn't shoot a wedding with an EOS M because you need fast AF achieve good focus, that's sounds like a personal problem, to me.   :-X
Not relevant. I am surprised that you are trying to defend using EOS M to shoot wedding  :o. Yes it can get some great to decent photos, but you will surely miss many. As Jim O pointed out the manual focus cameras of past had nice workarounds. EOS M is probably one of the worst camera I have used to capture the moment instantly (and its not only the AF, dead time between the shots has a good part to play too).

Regardless, this discussion seems to be pointless:

Can EOS M be used to shoot weddings: Yes
Can you get some great wedding photos: Yes
(Imagine a crazy scenario with 10 assistants carrying M toting nice L lens; randomly you would get some great keeper for every moment)
Are there better options than using M (provided same/similar glass): Almost everything else (except P&S and iphone)


Lets move on to something more meaningful....

"If only the new M had wifi and GPS and EVF and flippy outy screen and a flash and better video" ... and all that other stuff you people want - you'd end up with a EOS M brick.

It's small and compact. Fix the bugs and leave it alone.

If you want all that other stuff buy a SL1 or rebel.
+1 to leave it alone and just fix bugs

Seriously, how many people here would have bought it just for the product; without $299 deal?

I don't know...but I wouldn't have (and didn't).

I wouldn't have either; for sure....

Why should people overcome adversities to support imperfect product (only blind fanboys do that)?

Fair enough.  Can you please point us in the direction of that 'perfect product' your statement implies exists?  ::)

How about something that sells spectacularly well, far beyond expectations and makes incredible profits for its manufacturer? There may not be such a thing as a "perfect" product but, according to the marketplace, the original M body was thoroughly imperfect. I also don't see why it is a sign of good character ("overcome adversities") to waste money on that bad a product.
When Canon was pounding Nikon with spectacular sales of 5DII, Nikon fanboys were coming with the similar arguments. I am sure Nikon has been trying so hard just to please fanboys; profits have nothing to do with it  ;D ;D ;D.

You caught me here  :); I would have to say none but I am outside +/- 2 sigma of normal distribution and I have a feeling so are you (which side is not important ;D ). OTOH, deficient may be better choice of word (not perfect though).

The 11-22 isn't released YET. Doesn't mean the M is being abandoned. To think like that is irrational hysteria.

IMO, too many people who have never overcome adversity are talking too loudly about the M system. Success rarely comes without significant and numerous failures. Good business people know that.
Why should people overcome adversities to support imperfect product (only blind fanboys do that)? I never heard any romantic poetry about EOS M before this crash $299 sale  :D :D :D
Success also involves clear understanding of past failures and deficiencies. The current model really sucks for anything moving. And unless that is corrected it won't make any inroads into huge family photography market.  Crash $299 sales are good for recouping some money through accessory sale but not enough to make product successful.

EOS-M / Re: EOS M Hand Held Night Mode - how does it work?
« on: August 19, 2013, 05:54:41 PM »
This is just conjecture, but I think it is taking four quick high ISO shots and combining them to reduce noise.
Spot on. Since(if) noise is random, averaging of several frames results in reduced noise. Its different from HDR

Software & Accessories / Re: Best bag for hiking with a camera?
« on: August 16, 2013, 01:51:57 PM »
There is no shoe that fits all. After making too many mistakes and spending too much money and making shoulders sore, I have reached the following conclusion:
--If photography is my focus and/or hike is not really extreme, I prefer a good strap (whichever you prefer) and lowepro technical belt with appropriate accessories.
--If hiking is my priority, and I expect to jump/climb or for mountain biking, I carry super lightweight osprey with really minimal camera gear.
Over the time I have realized camera backpacks are worst of both for either of the situation.....

Pricewatch Deals / Re: Adobe Lightroom 5 $99 Shipped
« on: August 11, 2013, 04:43:59 PM »
Just checked the map and it says the world doesn't end at the border of the US  ;)
You are barking at wrong trees.
1) your earlier response did not indicate you wanted to ship it to Antarctica!
2) Adobe decides how to market their products. With cloud future, you will not complain about shipping fees but at the cost of monthly fee in the end bleeding more $$$$
3) Last I heard, world still had borders, countries, governments, taxes, tariffs, restrictions etc
If it is random rant, CR is a good place....,
