I am looking forward to see how all these different pixel shifting technologies work. In the case of Pentax, what is attractive is the rugged build. How long before a pixel's worth of movement becomes altered ??? I'm sure they have built in measuring backups, but this must be a very complex solution to creating a "better" foveon.

In reply to:

Dennis Linden: As tempting as these lenses are, the more impressive technology is the sensor shift introduced by Oly. It would be really impressive if the second generation of X cameras began to include in body IS, and by implication future sensor shift technology. Many people, myself included, question the limit at 16 Mpx on the APSc sensor. Just imagine for a moment Fuji X trans tech, no AA filters, OIS for everyday and Sensor Shift MegaPixel Resolution for landscape and special events, all in the very nicely sized Fuji bodies. ( The EM5 is a bit too physically small for my personally, I had one). Now, there's innovation.

So, not to belabor an unpopular topic, but I read today where Ricoh is quite far along with its sensor shift technology proposal. Then it struck me, the complexity of pixel shifting for the X-Trans array won't work. The basic premise of it is to avoid pattern. In order for SS to work, you need to have the Bayer pattern or something highly reproducible and predictable. Unless you change the RGBL of the pixel, X-Trans would not be able to do this, or it's CPU would catch fire trying to compute the sensor shift / pixel change combinations. Just an interesting thought.

Brilliant. Entertaining with ultimately honest conclusions. :-)

dharma108: Much as I really like Sony's recent entries into the FF and ASP-C market, I would be a little concerned if I was heavily invested in Sony camera equipment. They are now also not producing computers anymore--What's next?

Will the cameras self destruct now???

Ag80 and art99, but that's my point, I do print, and FUJI want's printing too, that's still a larger business for them and all the X series sales to date. When Fuji starts selling 4 K Tv's, I guess I'll give up printing and pick up a S3

On Street photography tips with Zack Arias article (152 comments in total)

I thinks it's a very nice look at how to do things, especially for those of use who are not so familiar with street work. the wifi remote control is something I have been dreaming of for quite some time, so I am looking forward to using that feature one day.

Dear DP Review. Can we request the ability to block certain people's posts. It would make it so much more pleasant to read the Comments section.

In reply to:

Valentinian: Questions (waiting for Jan 28 for answers):
is AF better than E M-5 ?
is EVF better than E M-5 ?
is shutter up to 1/8000 ?
is as reliable as the E M-5 ?

If the answers are "yes", if more lenses will come up, and Olympus does not upgrade the E M-5 within 12 months (forget the E M1 -that's for 4/3 lenses), then I will switch to Fuji

The AF question could be confused, but having owned an EM5, I think you are asking about Continuous Tracking Autofocus, which in my experience trying to shoot sports with the EM5, is a problem, as it is with all CDAF systems regardless of how fast they claim to be. We shall see. Importantly we need to see how it tracks with the longer focal lengths, not sub 35mm

In reply to:

edur: FINALLY!!!

This is the way a camera should be controlled.

Shutterspeed, aperture ... and ISO.

The three primary parameters of exposure.

Why did it take this long for camera makers to ditch PASM, and place ISO alongside shutter speed and aperture? This is much simpler and straight forward.

Thank you Fujifilm!
This will be my next camera.

I agree with you, but it's not the way everyone thinks. Where's the "sunset" mode ? some will complain. I wonder if they can give us who want it the manual control we need, but somehow also have a menu driven mode interface. It's all programming, it's all possible.

abortabort: Funny that there were 4 lenses in the first year, 6 in the second and 7 in the third, 17 lenses in total over 3 years. Sony announce 15 lenses over two years (5 on launch and 5 per year after) and they get panned for being 'too slow' in releasing lenses for their new system?

Not not saying kudos to Fuji, they seem to be the benchmark, just making note of the perceptions across brands vs reality - i.e. Fuji are considered the best and Sony the worst.

Harold, I was tyring to compare fuji x vs sony e on only apsc size sensor. eg Sony 1.8/35 vs Fuji 1.4/35

Perception is never reality. As a former m43 user, they had lots of lenses, but that's only part of the equation. As I now look at Fuji vs SONY, if you look at the Sony lineup, at each focal length, the Sony lenses appear just a bit slower, heavier, and cheaper too. It all depends on what it is you perceive as your need.

On Sony A3000 preview (678 comments in total)

I would like to offer that I in fact prefer a button to switch between evf and LCD. I became quite frustrated when my em5 thought my hand was my head and blanked the LCD just as I was going to use it.

For me. This grip makes it the first sensible nex body.

groucher: Impressive result but why suffer for your art? The stitching could have been done in about 2 minutes in PTGUI (or similar) and the local adjustments would have been far easier in NX2. Photo$hop has its good points (e.g. lettering, free transformation and canvas sizing) but the type of work required for this example isn't exactly its forte.

yes you can

On Buyers' Guide: Best DSLRs and ILCs for under $1000 article (91 comments in total)
In reply to:

Heie2: I am a Pentaxian fanboy through and through, but I say this in the most objective way possible:

The best value for money DSLR's/MILC's under $1000 are the Pentax K-500 ($595 w/ 18-55 kit lens), Pentax K-50 ($696 body or $776 w/ Weather Resistant kit lens), Pentax K-5 ($500 used body - discontinued), with the number one spot for "best bang for your buck" across the photographic world given to the Pentax K-30 ($479 body) and the Pentax K-01 ($299 w/ 40mm pancake lens) despite what is undeniably a controversial body design for DSLR/Mirrorless, respectively.

Even the lowest entry level isn't skipped over for $1000+ features such as 100% penta PRISM viewfinders and DUAL command dials.

Anyone that tells you otherwise is delusional.

Also to consider that K mount will take those M42's with adapters, but F mount can't due to register depth. I use the old lenses on the EM5- but had I gotten a Pentax, I would have had a larger and better sensor ... I can't adapt (without gimics) the M42's to the D90 I have.

Summer2379: Hi everyone,

Regarding Cosima lens I am having a burning question which I cannot find the answer despite many many google search...

May I ask which adapter I need to use an old Cosima 28-210 f3.5-5.6 for NeX 7. I have no idea at all, kindly help!!

Thank you very much!

( sorry if I post the wrong place )

it was PROBABLY a MD mount - but it may have been manufactured in other mounts, so unless you know what mount it is, there is no answer possible.
