On article SLR Magic announces anamorphic lenses for filmmakers (32 comments in total)

Given the new lenses would exist, will special projector lenses follow or will these lenses in reverse be able to serve as projector lenses as well?

KLO82: Why don't you make an option to "like" the features/ articles? Just like the way we "like" the comments.

Because it wouldn't matter? DPR write their features/articles because they reflect what they think.

Digitalis32: These lenses will never outlive the true immortals: pentax takumars.

The bombs will fall and the earth will be scorched: Keith Richards, three takumars a K1000, and five cockroaches will be all that is left.

Sorry for Keith

Quoting from the article itself: "The downside to the design is barrel distortion".
Hey, what about the other remaining optical aberrations? There is no such thing as a silver bullet.

bernardf12: Olympus dials are so nice to use, you turn them even when the camera is off - sad but true.

Glad to hear I'm not the only one disliking the fully articulated screens. It's a deal breaker for me.

Weather sealing is expected on all cameras nowadays, as is dual AF (PDAF/CDAF).

We are making progress, new cameras have only about 2-3 serious omissions nowadays, unless it's a Sony :-)

"Weather sealing is expected on all cameras nowadays..."
Actually, it is safe to say that all cameras nowadays, resp. their sensors, are well protected against stray light; well, more or less.

Der Steppenwolf: There are a lot featured photographers here that have ONE thing in common.
Could you guess what it is ?
A tip, it's got NOTHING to do with photography at all.
DPR has changed. A lot. To the worse.

At Den Steppenwolf:
Don't consider yourself a philosopher and just utter a few vague words expecting then everybody as wise as you to understand them at first glance.

PowerG9atBlackForest: Hey boys, I am an amateur having joined dpreview in 2008 and now shooting with Olympus MFT cameras. I could not resist having a curious side-look at your new Nikon D5 as it popped up here. You are not serious, are you? This is what they build our brick houses from at home ;-)

At LJ - Eljot: I simply didn't notice it before. May be because I have been used to MFT sizes since a couple of years not having payed attention to the same degree to professional C&N cameras since then. Surprises always come unexpectedly.

Rishi, no, not really. It just came as a shock to me simply because from my past ten years or so I wasn't prepared to be confronted with cameras of that size. However, I do appreciate that Pros will need that. ;-) I didn't want to offend anyone.

No mention of CRI values - press releases never do and dpr doesn't care. By the way: CRI >93, Manfrotto says.

PowerG9atBlackForest: "...Sensor size plays a large part in determining the image quality a camera is ultimately capable of and, in general, the larger a camera's sensor, the better the image quality..."

What is written like a rock solid statement and probably is meant as such, under the light of reality, has to be considered as a very private opinion of the three authors - I can't believe Richard is amongst them. At least, he should know better.

@ObelixCMM: Well actually I did and I am doing it all the time. There are two issues mixed here:

1. Noise, admittedly is more a problem in small sensors. It is also more a problem with ISO values. The threshold for it varies with size of sensors (see above) and with the way signals are processed. Noise is only one point when discussing image quality.

2. ISO, put two cameras with different sizes of sensors side-by-side to capture the same object; given an identical ISO value, you will find that they both will use the same value of exposure (EV) for this shot.

Sorry ObelixCMM ;), I still think you are wrong when you wrote "Exposure stays the same because ISO 100 on M4/3 is same as ISO 200 on APS-C and ISO 400 on FF..."

Dr_Jon just stated "With the same f-stop any size lens gets the same light per unit area...if you select ISO 100 the exposure will work out regardless of camera...".

This must be correct because the amount of light/photons per unit area remains the same regardless of the sensor size.

"...About half the photons gives about sqrt(2) or 40% more noise relative to signal. Which will massively dominate the sensor noise almost everywhere..."

So far I have been under the impression that the effect of photons not converted to electrons producing noise was locally restricted, i.e. to the very loci where they actually hit the sensor.

If you are right in that this is a global effect acting across the sensor I have to admit that a larger sensor will benefit from lower noise compared to a smaller sensor.

Exposure stays the same because ISO 100 on M4/3 is the same as ISO 100 on APS-C and ISO 100 on FF, exposure wise.

So Dr_Jon, seems pretty clear that ...
you're considering noise only and nothing else when it comes to judge image quality?

You also think an object will need different exposures depending on sensor size because "bigger sensors capture more light"?
