Is a 1/1.8" (7.18 x 5.32 mm) sensor sufficient for 10mp and 12mp?

Is a 1/1.8" (7.18 x 5.32 mm) sensor sufficient for 10mp and 12mp
of data?

Or would a larger sensor be preferrable, such as a 2/3" or even
4/3"?

Thanks

 

What ISO do you want to use?

80-400 probably

80 - perhaps OK
400 - noise limited

You've asked this question before, but worded a bit differently.
I thought that you understood the many answering replies, but . . .

The answer is that it depends. On the photographer. On the
photographer's expectations. On the year. On the types of pictures
you'll take. On all sorts of things, and for some photographers,
not only will a 1/1.8" sensor forever be insufficient, some only
accept FF sensors, deeming even APS-C sensors deficient due to their
"insanely small pixels". Many others think that 1/1.8" sensors are
more than sufficient for their needs, even with their large numbers
of small pixels. The answers you get can only represent
individual's preferences, and while it's unfortunate, you really
have to form your own preferences by examination and testing, either
of your own images or those taken by other photographers. If your
preferences are formed by agreeing with someone that makes a good
case for why *that individual* likes a particular type of sensor,
you'll never have the satisfaction of discovering for yourself what
works for *you*. Some find it simpler to be followers, becoming
disciples of a photographic guru. And if that guru suddenly decides
that not only are 4/3" sensors too small, now even APS-C sensors are
as well, followers will follow to the Full Frame Promised Land, even
if they've never made a single print any larger than 8" x 10" and
have no desire to ever do so.

If you can't afford to buy and try many cameras, you could easily
download images produced by those 1/1.8", 2/3" and 4/3" sensors, and
determine for yourself if they're lacking in the resolution that you
want, or are too noisy at high ISOs for your purposes. I think
that this has been suggested before. The answers that you're
seeking will come from people whose tastes differ. That doesn't
mean that some are right and that the others are wrong. What I'm
trying to say is that at some point you need to end the asking and
do your own tasting.

 

I prefer top posting for quick replies so people do not have to
scroll all the way down.

thanks for the reply.

 

I was asked to be more specific, so I chose a specific sensor
size and two specific resolutions.

 

But my reply was to your OP, the first one in this thread. It had
nothing to do with David's reply that asked about the ISO you want
to use. Or was the more specific question one that was posed in
another thread? If so, you might have have included some "in
context" quotes.

It appears that you missed the "big picture" of my last reply, one
that might have had you see that introspection would be more
beneficial than asking more specific questions. But that's what
works for me, and evidently doesn't or won't for you. As I hinted,
implied, suggested . . . I think that previous replies contained
enough information to answer to your new, specific questions,
assuming that you'd spend enough time digesting them.

 

On my screen, both your comment and my replies fitted without scrolling.
I do agree that we see far too many posts where the dross in not
sufficiently trimmed. I prefer to keep the text in top-to-bottom order of
writing, as used in most Western books, newspapers, magazines etc. for the
last several centuries.

I'm glad you found my answer useful.

David

 

I keep hearing from students and folks with laptops that since
they only have 800 vertical pixels, they get annoyed scrolling
down. Hard to please everyone, it seems.

Anyway, thanks.

 

I should expect that all other things being equal, a larger chip would
result in less noise. I think that's probably as far as one can take that.

 

Not really, if messages and answers are properly trimmed down
to the bare essence, there should be no issues. All it takes is a bit
of snipping and a sense for nettiquette and logic.

 

I really wonder at people who seem to think pressing the down-arrow
key or the page-down key is just so difficult.

Define "sufficient".
It depends on what you find acceptable.
You can go to many sites that review cameras and look at the
representative pictures, and even at specific pictures designed to
show noise (I assume you're worried about noise from these sensors at
the ISOs you mention). Decide for yourself, because we really can't
decide for you.
If the noise is acceptable to you, then the sensor is sufficient for
your needs.
It really is that simple.

There is no solid concensus. Some people get irritated that they
have to scroll, and get mad at people who don't top post.

Some people freak out about how quotes are done, like in Outlook
Express, some don't care. I use OE-QuoteFix and that seems to
satisfy most folks.

I prefer Plain Text, others like colors and bolding text and what
not. Some like to send HTML messages and get mad at others who
don't like to view all that stuff.

Life happens. It's just not worth stressin' over. There are so
many more important things, so sometimes I try not to nitpick.
It just upsets folks and unless it's something that is a core
value or belief, letting it slide is something I can live with.

 

Fair enough.

 

Maybe it's the funky locations of the arrow keys on different
laptops or also the different finger pad things. I know that I
just totally can't get used to having to hold down a blue
function toggle to be able to type in F1, F2, etc on some things.
I just try to go along with what makes sense.

I see their point - scrolling can be a total pain, so I listen
and am like "ok, I can adjust - to you the thing is valid and
that's cool"

Like how some people totally freak out if someone misspells or
mis capitalizes or uses apostrophe's wrong. I try to focus on
what is being said. If I can understand what they are trying to
communicate, that's pretty much good enough for me.

Some people get mad at windbags who spend more time trying to
articulate an answer around the question or criticizing the
question itself instead of just answering the thing, and some get
mad at people who don't get into lots of detail because they
think if they give a short answer they are just "blowin' them
off" and stuff.

Human behavior is just wacky all over the place. I just keep
eatin, sleepin and grinnin. Seems to get me through the day.

 

Ok. I was actually not looking for a terribly specific answer,
just a general one like "It seems that 1/1.8" is really not that
effective about 6mp, in my opinion" or something like that. Or
maybe "I think 1/1.8" sorta maxes out at 8mp in general before
you get to a point of diminishing returns." No biggie. Thanks
for the reply though - I do appreciate it.

 

AFAIK the OP wants an unbiased, blanket opinion?
I don't think that's possible in today's world.It's not like asking a
question of pure physics, "how many HP of motorage needs that deep well"?It
depends on what anyone likes, and many other regulars here suggest to read
reviews of cameras, and go to a shop and see for yourself how that camera
"feels" in your hand.I bought a Kodak CX 7300 because then I didn't have
more money, now with 144 euros I'd get at least 5 MP (the CX 7300 is 3.2)and
I'm making lots of A4s.

 

"Alfred Molon"

That's why I often prefer to answer at the top of the message. The years
that I spent on Fidonet (almost from the very beginning of this network
which is already old) made me do that because it's physically impossible to
review hundreds or even thousands of messages through the night scrolling
them down each time when you open a new one. So we had a simple official
rule to add the answer to the top of the message and trim the worthless
parts to avoid overgrowing of the messages. I like this rule and I actually
spent so many years following it that I even can't imagine another one as
more appropriate. Another one significant rule - don't overquote!

The downside of all that are the people who started their network activity
from public usenet newsgroups only and they have no idea about the roots and
advantages of these simple rules and what's that to read a few thousand
messages in one night and even get some information from them These
people usually argue against those who do that, in my mind, in more correct
way by adding their answers to the top and deleting the overquoting. Usually
2-3 lines from the previous message is more than enough to remind the people
what's all that about. Also I'd never write a message completely repeating
the previous post with my comment in one single word like "Agreed". It would
force a few thousands or real people to read this worthless message without
any new info that they can learn from it.

Logically all that is harder because in real life we add our comments after
quotes, it's also hard to delete the secondary part from the previous
posting, especially for lazy people, but why all others should not be lazy
to real/scroll all these quotes down? My own experience shows that it's
probably hard, but that's a network rule and it's hard only in the very
beginning, but then after some experience the things become obvious.

As for me I can follow any rules absolutely easy now because I used to see
many people, mostly newbie, barking at others because they are doing the
right things.
