On article What is equivalence and why should I care? (2406 comments in total)

kpaddler: Your summary is simplistic and incorrect when it is considered in absolute terms.

If you argue that when you downsample/upsample images to one size and compare them, then yes, the larger sensors fair better, not surprising. If that is what you argue, then do so, but there is little value in that when you are trying to explain "brightness" of different sensors, but this is opposite of educating people.

A yellow flower with light value of x at 100iso, f2.8, 1/125sec, will produce exactly, 100% same light value on sensor regardless of sensor size or focal length.

I'm objecting to your summary paragraphs, not what you know.

@Richard.

I think I understand what you mean. But not sure if the article actually clarify anything, I actually think there is more than one aspect to clarify. One of the reasons I picked at your article is that, after decades of playing with the toys of all formats, I thought replacing one of my older dslr bodies with a low end medium format, maybe. But I have not any one simple reason or rule that would tell me inherently the bigger sensor will win the highest total score.

And that's why I don't agree with a generalization of the larger sensor makes life easier to get the better quality....years ago while on a personal photo shoot in the Badlands I learned my $400 olympus c4040 took much better pictures than my 15k Linhof outfit, because the Linhof served better as sail in the wind than a steady camera in the wind. So, every format has its straighten but not everything sums up to positive value.

@Ian. Funny, how trying to simplify things leads to complications :-)

I didn't get where you are trying to go with your explanation...

You can apply my example to film too. Instead of dpi, enlarge the film by a factor of 10. Mind you exposure time for print goes up for the smaller format film, not because it is darker but because your enlarger head goes higher or farther. The resulting images will be/should be different size prints but the exact same grain structure and depth.

Lets talk about this sentence :-)

"then the area which you capture it with means that the total amount of light is different and the larger sensor has to opportunity to capture more of it."

What does "opportunity" mean? I think you are using this word because your argument is about what a picture "might look like". While I argue if you take 2 identical performing sensors(lets say the latest of CMOS family) but different size, then print boat of them at the identical dpi(let dpi define the print size). You will get very similar outcome in terms of overall picture quality as far as light, lens, etc. In the old days, leica photos would kick the pants off the hasselblad photos regularly simply because of better lens given everything else was equal..

With this article you were trying to clarify things???

1. People don't use large format because it gathers more lights. There are plenty of reason but light gathering is not one of them.
2. By now any high school kid knows the noise is primarily is effected by pixel density per real state. That is to say, a 100mp medium format could have roughly the same noise as a 25mp of a FX format.
3. Show me a single light meter that has the recording medium "factor" in light metering process???
4.A 1lx source of light is 1lx regardless of the size of the medium recording it, assuming it is being captured in the frame

Where do you get off with these non sense

kpaddler: "The Sony a99 ll will be available on time – but in very short supply"

Oh man :-( I'm running to the store to put my order in NOW. I don't need to see what it is, I just buy and be ahead of the crowd....

yup! just to be sure I get one ahead of everyone else, I sent my son to place an order too, because it was one per customer.

We know there won't be enough supply of these to go around, Sony said so....these cameras won't be sitting on the store shelves collecting dust...

See what a phone can offer, why would anyone pay for an over price compact camera these day?

Good for you, keep asking questions, that's how you learn.

VENTURE-STAR: Yet another ridiculously expensive and rather silly product from Leica. What are the people at this company thinking when they put products like this on the market? Only a handful of well heeled collectors are going to be customers.

Leica company is making all the right decisions for the brand. This company came back from the death. The couch pundits have a lot to learn about this brand and people. It is really irrelevant whether you and I ever buy anything leica or not. They have "balls", they identify a market and go after it. I can name a handful of japanese companies that threw in the towel and disappeared.

yzhenkai: How to choose between GX8 and GX80? Confusing...

Yes, but these changes can be consolidated in fewer models to bring the cost down, rather than cannibalizing their base customers...

In reply to:

PanchoVilla: Is it even possible to make f/1.2 lenses for the Nikon F mount? The lens bayonet might be too small.

Nikon has 50mm 1.2, and once upon a time had 58mm 1.2, and 300mm f2. So, yes, the bayonet is large enough for earthly lenses

In reply to:

Nikonandmore: I have the feeling, just about all lenses now are "Leica" and MF price range. Sony, Zeiss, Canon, Nikon.. amazing! I don't understand how these manufactures survive to sell enough of these or how people manage to have money to feed this price frenzy. It will only take cell phone sensors, lenses and technology to get a bit better FOR ONE to buy DSLRs anymore. This market is dead and at these prices, sinking faster and faster. Costs 10 grand (or more) these days to buy a pro/enthusiast grade body and 2 or 3 lenses. Sorry, but this and it's pricing momentum is all becoming absurd. And mind you, these new lenses are all mass produced in 3rd world countries and with more and more dubious quality control. Long gone are the "Made in Japan" days with solid products made with extremely qualified manual labor, excellent quality control AND real long-term post sales support! Indeed Leicas start looking really affordable..

"...these new lenses are all mass produced in 3rd world countries and with more and more dubious quality control. Long gone are the "Made in Japan" days..."

That may or may not be true(more like it is irrelevant), but what you say applies to all systems and manufacturers(leica excepted) regardless of sensors size(because that is really core of your argument).

PhotoKhan: In my calibrated monitor there seems to be a yellow/greenish veil cast in all the samples.

Definition is, indeed, very good but nothing to write home about for a MF sensor.

I was hopping to be more impressed. Maybe with the next batch of samples?

@biggercountry

You made the harshest comments about others than anyone else on this subject. So, go ahead and vent if you need to feel "bigger"

Haven't tried gx80, it is smaller and somewhat simpler. Frankly I don't know the point of it, all manufacturers have saturated the market and desperate to create a new need.

Ask why mercedes benz have so many different "classes" now with little difference, they used to have 3 sedans, plus a couple of coupes. Same with audi, bmw, etc.....

Calibrate your calibrating device...

This is a genuine paradigm shift and I wish Hassy all the best with this one ...

Well in the good old days it was courtesy of Kodak, Agfa, etc. Oh wait, everyone relied on Kodak etal.

Lets not forget Zeiss.

Rude at the concert???? You sure you are not kissing apple's behind for this future? Let those concert performers tell the fans they should not be taking pictures when they payfor the tickets.
