SmilerGrogan: The more the megapixels the beefier the tripod; DPR did a cool ball head test 100 years ago, perhaps it's time to do a tripod vibration

Here you are :-)

DongaMogudu: "And asking people to invest in a small camera with the expectation that they'll use larger EF and EF-S lenses doesn't sound like the easiest sell."
I guess, DPR forgot to tell that (small body with big lens) to Sony for all these years.

@Richard Butler
Autocorrect much? :-D

0MitchAG: Where are the equivalency police?? I don't know whether to love or hate the 7.5mm without them!

Hate is always a safe bet.

On article Real world test: The Panono is a 108MP spherical camera (157 comments in total)
In reply to:

Roman Korcek: If the cameras are fixed and thus their coverage of the scene and mutual overlap is exactly known, why does a complicated stitching algorithm need to be there? One simple stitching method should be sufficient for any possible image, no? Someone enlighten me please.

Thank you Mark.

Yake: When we have those whispers of ideas, a lot of people don't pursue them because we still have to earn a living. It's a necessity, not a choice. How nice that one photographer can float through life on philanthropy and big ideas, apparently unbound by conventional things like finances and time.

@Eric,
Interesting, thank you. I was not aware that quotation marks cannot be used for paraphrasing, let alone considering there are no paraphrase marks to use. I would edit my original post to include a "paraphrased" since it really seems it is not obvious it's a paraphrase but now I can't anymore. Oh well, next time I will make it more obvious. I learned something today, thank you.

@Eric,
Well, it's clearly not a quote if one cares to check the article. I don't understand how one can mistake it. I have never seen anyone writing [this is a quote] or [this is a paraphrase] behind quoted or paraphrased text.

@Sean,
Oh, hi again! On a witch hunt now, are we? Well, good luck! :-D

Huh? Not sure what you mean, I was not quoting anyone. Perhaps you are mistaking the paraphrase for a quote?

@Sean,
Nice to see you here, too! I see you are having fun checking up on the comments of people you disagree with. That's a noble goal! Enjoy the quest!

On article Accusations fly over Fukushima photos (88 comments in total)
In reply to:

Sean65: The photos were a joke. They were not about Fukushima but all about the idiot who decided he would be the subject matter of each image. Strolling around dressed like a chav wearing a respirator, which would have done absolutely nothing to protect against exposure of radio active waste.

Is this the future of photojournalism, the me generation unable to resist the banal temptation to appear in all their own photos.

@Sean,
I am not interested in this discussion and I stand by my original statement.

Gotta love internet comments.

@Barney,
I have to agree with @Yake here, there are valid reasons (eg. securing a good financial future for one's children) why people don't always take risks and follow their dreams and what Jeremy said came across a bit belittling - "oh, they don't follow their dreams because they're scared, well, I am not!". Good for him but it's no reason not to show some respect to those who don't. I concur he probably did not mean it that way, still it could have been worded a bit better.

StevenE: People question m4/3 format for good reason when we see lenses like this at US$1300.
This is equivalent to a FF 24 f/2.8, which can be had for Canon at US$550, less than half the price and it is smaller and lighter. Even more significantly, you can get a FF 24mm f/1.4 from Sigma for US$850, that's a US$450 savings, and there is, and likely never will be, a m4/3 equivalent to that!
So, although it has it's uses, micro 4/3 is a compromised format

@Great Bustard
Well, your link says something different than you do in this thread. I agree with your link. I disagree with what you are saying here.

"Pixel count has little to do with overall noise"
Huh? You specifically say in your post in your first link, "So, are more pixels more noisy than fewer pixels? For sensors of the same generation, yes they are." I am not really sure why you are now saying the exact opposite.

"In short, it's the total amount of light making up the photo that matters."
Let's take 1 kilogram of light and shine it onto an area covered by
- 4 pixels
- 1048576 pixels
Which of the resulting two images will be noisier?

@Great Bustard
"Again, not just for DOF, but also for light gathering. For example, 12mm f/1.4 1/100 on mFT puts the same amount of light on the sensor as 24mm f/2.8 1/100 on FF"

This is only valid if you are talking about the same amount of megapixels on both, which would mean 4x smaller pixels on the mFT sensor. If you keep the pixel dimensions the same (ie. "cut" 1/4th of the FF to get a mFT) then your comparison is not valid, at least with regard to noise.

On article Road tripping through New South Wales, Australia (32 comments in total)

I'd love to read an article on how the first image ("Sydney Opera House and Harbor Bridge") has been post-processed.
