DELETED88781: Small sensor is not good regardless of any feature.
Entry level FF DSLR has 4 times bigger sensor and only 200g more weight.
Cost? Almost the same.

It's still a matter of weight/size vs. IQ. My m43 gear is clearly lower in DR/color fidelity than my D800, but it's also way lighter, especially when the equivalent FOV lenses are taken into account.
Unless under extreme DR situations or when I need to really lift shadows, or I need really low DOF, my m43 gear is way good enough for most things.

ugh! Do they really make any money doing this?

bcalkins: Finally - EVFs come to P&S cameras ! Be nice to see a capable EVF in some of the larger sensor compacts...

EVFs have been in the P&S coolpix line in the past, but were dropped. My old CP8400 had an EVF, fully articulated LCD, built-in flash, hot shoe, magnesium body, etc. and then the CoolPix line became dumbed down over time. Nice to see these things back in the CP line.

However, I'd give up the 28-200 equivalent lens for a 24-100/2.8-4 lens and a the 1" sensor from the Nikon 1 system . . . that would be a killer CoolPix.

SeeRoy: Why doesn't one of the manufacturers release something with overall improvements in IQ (bigger sensor, faster lens etc) keeping the size down by eliminating the LCD screen?

Apart from setup (and the chumps who chimp all the time) I think many people would trade it for overall performance gains if the essential functions were externally accessible and setup could be done via an EVF. After all, there are plenty of overpriced cameras out there lacking a viewfinder - which many of us find indispensable.

Still, adding an EVF to cameras in this sector: about bl00dy time too.

Tough to show my kids or wife the image I just took of them w/o the rear LCD

Looks like it's a very much evolved descendant of my still-working CP8400:
- Fast zoom lens
- EVF
- Articulated screen
- Hot shoe
- Built-in flash

If only it started at 24mm FX equivalent . . .

Hmm . . . don't know about the price, but many times I'm out with just my cell running, hiking, etc. and I don't want to bring along a camera. This MIGHT be an attractive thing to have.

But really, I look forward to the creative things that people will do with such a system. Can you connect more than one camera module to your mobile device so that you can take multiple simultaneous images from different locations?

On Sigma 18-35mm F1.8 DC HSM Review preview (333 comments in total)
In reply to:

Frank_BR: In my opinion, the conclusion that "… the lens is effectively diffraction limited… (because) there's no measurable increase on stopping down" cannot be drawn from the measurements.

A perfect (diffraction limited) f/1.8 lens produces an Airy disk with a diameter of 2.4 µm, and a ultimate resolution of little more than 6000 LW/PH for an APS-C sensor (22.2 x 14.8mm). The corresponding MTF-50 would be about 3000 LW/PH, which is considerably higher than 2000 LH/PH measured by DXO. It is clear, now, that the measured "low" value of 2000 LP/PH is not directly related to diffraction limits, at least for the 1.8 aperture.

In conclusion, it is impossible to say from the data that the measured value of 2000 LW/PH was given by sensor limitations (3648 pixels height), lens limitations (aberrations and/or diffraction), or a combination of these factors. Probably the (excellent) behavior of the Sigma lens at 1.8 is due to a combined effect of aberration and diffraction.

Exactly my thought when I read that. I have several lenses that don't get any sharper when stopping down when used on my D800 and they certainly are not diffraction limited.

In reply to:

zodiacfml: Greatly needed by the 12MP FF of years ago but not so much today. What baffles me are MF cameras that didn't have such filters especially with their bigger pixels and larger lenses. Anyway, still a good patent that might be useful.

Exactly - one of my biggest gripes of the 12MP sensor in my D700 was the heavy AA filter. Many times I would have loved to been able to turn it off completely. I really think this may be more focused on video applications with high MP sensors, but we'll see.

Nikon also has a patent on using a special lens element to act as an AA filter - I wonder what will happen to that technology.

That's just plain crazy. The actual street price needs to be waaaay lower than that to get people to buy this (and it better be a stellar camera too).

vodanh1982: Wow. the 75mm f/1.8 is the sharpest m43 lens and Sigma made it.

We don't know who made it though - just that it looks like it's a Sigma optical design.

In reply to:

jhinkey: It's one thing to design the optics, another completely to design the mechanical and electrical components and figure out how to get it manufactured to the price point and quality level that is desired.

Sigma has likely had the capability to design excellent optics for years, but the mechanical/electrical design & manufacturing may be on Oly's side of things.

I think a lot of companies are capable of stellar optical designs, but getting them to be made small enough, cheap enough, reliable enough can be a skill that perhaps only a few have.

Yes, I know what Sigma has been doing all these years.
They know how to make decent optical designs with just OK mechanics/reliability (until recently).

My point is that it takes skill to make something of high quality AND keep the price down/reliability high and perhaps Sigma is behind on this aspect until just recently.

jhinkey: Shot across the bow of Nikon and Canon.
As a Nikon guy I've been expecting this and I believe will push Nikon over the edge to bring out a new APS-C interchangeable lens camera line with a new mount and no mirror - the natural progression of their DX cameras.
It's my theory as to why Nikon has not put out a lot of high end DX lenses - they knew DX would be going mirrorless and require a new lens mount to make their bodies smaller, thus why put out a lot of expensive DX glass that would then only be useful via some sort of an adapter.

Interesting times ahead.

Exactly - CX has not done well, APS-C going mirrorless via Sony, Fuji, etc. will put a lot of pressure on Nikon to do the same with their DX lineup. You can bet that Nikon has been working on a mirrorless DX camera (and FX for that matter).

G3User: These images don't impress me. Camera manufactures strive to produce great images from their products and then this guys throughs a yellow instagram filter on them, very unprofessional. I would expect this from my teenage daughter but not a pro. The expressions of the 2 people at the top are not very nice, they are saying to the Frank " I have no respect for you, put that camera down".

Dude, it seems you've never seen the show. The staging, lighting, and post processing all seem to work to convey the mood and storyline of the show.

Those guys are in character - these are not candid shots.

It's not the 1" sensor that put me off, it's the bodies and lenses - lack of controls/features on the bodies and lack of a selection of lenses.

The last good Nikon small-sensored camera in my opinion was the CP8400
- Metal body
- EVF
- Swivel flip out screen
- Built-in flash
- Excellent IQ decently fast lens
- Good ergonomics
- Optional grip
- etc.

The Nikon 1 V2 was a step in the right direction, but it was too late for me as I already bought into the m43 system to give me an option to lugging my FX Nikon gear.

Nikon is late to the small mirrorless game and didn't help itself with mediocre offerings.

The people I know that would be in the market for a Nikon 1 system have already been sold a DSLR by Nikon - they've saturated the market with DXXXX series DX DSLRs and lenses - and there is no real compulsion for them to sell their DX gear and get a Nikon 1.

Nikon has failed in its marketing trying to get entry level DX users to buy into the system due to the price and DSLR market saturation. AND they've failed to convince folks like me (I have a full FX Nikon system) to buy the Nikon 1 because of the lack of sophisticated bodies and upscale lenses at launch (and present) that I'd want.

I bought a m43 GH2 because the sensor was good enough, the body features/ergonomics were very good (EVF as good as a DX camera, swivel LCD, external controls, built-in flash, etc.), there were plenty of great lenses available, and very good support for legacy glass.

Ashton didn't help either. Nikon has no one to blame except themselves for an anemic product and associated advertising campaign.
