On Sigma announces all-new 50mm F1.4 DG HSM 'Art' lens article (245 comments in total)
In reply to:

Absolutic: Would not it be cool if this lens embarasses the $4000 Zeiss...... plus the AF?

Totally unreasonable to expect it to match the Zeiss, which is a no expense spared tour de force. If it's even better than the current Sigma 50 f/1.4 which is excellent, it'll be superb and more than good enough for 99.99% of us.

Now when are those slackers at Canon going to finally offer a 50 f/1.8 IS, 50 f/1.4 and 50 f/1.2L II?

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.

Actually f/2.8 on m4/3 is exactly like f/5.6 on FF. The smaller sensor gathers much less light and having a two stops faster lens allows it to gather the same amount of light as an f/5.6 lens on FF. The ISO performance of the smaller sensor is ~ 2 stops worse (all things being equal). Thus shooting a 42.5 f/1.2 @ f/1.2, ISO 100 on m4/3 gives same results as shooting 85 f/2.4 @ ISO 400 on FF, in terms of noise, DOF, background blur.

On Nikon AF-S Nikkor 58mm f/1.4G review preview (412 comments in total)

Sorry for this sort of money for the lens to be poor wide open is just not acceptable, especially in the easiest lens of all to design, a 50-60mm prime. When one can buy a Sigma 50 f/1.4 that is sharp wide open, has beautiful bokeh, low vignetting and only costs $500 and I'll bet the Art series version is going to be even better, then why waste money on the Nikon? The world is awash with excellent 50-55mm primes and ev en if in every other regard the Nikon is excellent, it still doesn't grab me as a sensible buy.

On Samsung NX300 real-world and test scene samples article (92 comments in total)

Samsung still making cameras. They have a nonexistent profile IMO. I was reading an article from 2008 about Samsung's bold plans to be #3 by 2010. I guess that document wasn't read by any body else at Samsung. Also they had bold plans to have FF DSLR, that disappeared quickly. I've never seen anyone using an NX camera, just their Samsung smartphones. Like a lot of things Samsung does, they can't quite reach the pinnacle.

IQ looked ok, but 99% of the shots were at ISO 100. Why not a mix of ISOs. Any of the advanced P&S cameras these days can turn in excellent IQ at base ISO, no need for a big sensor for that. The one ISO 6400 shot was quite poor.

thx1138: Well well, DxO mark claims Df has best low light IQ of any camera ever, yet the dpreview test scene shows that at high ISO (RAW) the Df and D4 are not even better at the pixel level than 6D, which can further be resampled to 16MP for even better results.

HowabaoutRAW, you still pushing your own myth about resampling I see. Not sure what universe you live in.

On Have Your Say: Best Lens of 2013 article (89 comments in total)

Clearly the canon 200-400 f/4 is most innovative and best quality zoom ever, despite it's insane price. Price should not be a consideration in the best lens category, so it's low score is ridiculous, even though I wouldn't buy one unless I won powerball. The built-in TC is a master stroke and provided serios technical challenges. After this the Otus for sheer IQ alone should be high on the list. How the Nikon 58 f/1.4 makes the list when we already have a vastly superior lens to choose.

In reply to:

Jogger: I dont understand the focal range selected.. esp. at those apertures.

For wildlife work, maybe 300-600 would have made more sense.. .there are plenty of lenses that cover up to 300mm.. esp. if speed isnt a concern.

300-600 far too restrictive a range. I'm delighted it's 150-600. I use a 100-400 and while I'm predominantly using the 400mm range, there are plenty of times I wished it could go to say 70mm.

A perfect travel kit would be 16-35, 24-70, 70-200, 150-600.

epozar: Nice, but what's revolutionary?

The price for a start. Even at $2K it would be a bargain let alone the insanely low $1069. Also amazingly compact for a 600mm zoom, and quite light, same as the Sigma 150-500 and only a little larger, yet has the same aperture.

In reply to:

BobORama: So its a $140K camera system that makes even the most exciting jobs look boring? OK, the slo-mo flames are nice, beautiful, and the water emerging from the nozzles was interesting.

I guess the REAL advantage is that you can shoot a scene at 1000FPS and then in post production get whatever frame rate you desire to achieve. Smooth adjustments in the time scale give you very cool effects. And if you were shooting Inception 2 - it might be useful.

The scene does underscore how much water is entirely wasted. 80% of it forms huge globules that never actually participate in putting the fire out. One of the profs I had years ago was involved in alternative systems and things like a pressure washer, or even steam put out a fire more effectively, and with so little water its truly amazing.

If you can put out a fire with 80% less water, you downsize every aspect of operation, from the tankers, trucks, ... the need for hydrants. Also less water means less water damage.

-- Bob

Given how god damn awful American beer tastes (not the microbrewery stuff), filming it at 1000fps @4K might be the only thing that leaves a nice taste in your mouth.

Laszlo13: Weird, the camera JPEG looks much better on the 100% close up - both sharper and without artifacts.

What you are seeing is that the ACR reds/oranges are too saturated and the flower has lost some detail. If you decreases saturation in that channel you will see that detail again. Adobe doesn't handle reds very well.

On Fujifilm XF 23mm F1.4 R real-world samples gallery article (125 comments in total)
In reply to:

tipple: One thing is apparent from these images, if Fujifilm enters the full frame market, with the results achievable with the XTrans sensor or even their conventional Bayer sensor, Canon and Nikon will have to keep on their toes! Fujifilm has demonstrated very good support in updating lens and cameras for their customers. It is apparent they are in this for the long haul and that bodes well for all photographers.

"Fujifilm has demonstrated very good support in updating lens and cameras for their customers."

Doesn't this just mean they didn't get it right the first time and have to keep addressing issues? Sort like releasing a buggy game and then having to release a frequent patches.

On Swimming with the Nikon 1 AW1 article (199 comments in total)
In reply to:

jennajenna: Biggest problem with the nikon frankly is the lack of wide angle lenses. The best it can do is 27mm. The olympus tg2 is 25mm BUT with an adapter it can get as wide as ~ 21mm. That is massive as a field of view advantage (over 20%) compared to the nikon's 27mm max - and the real world of underwater video or photos... you want a wide vista of your experience. Also the tg2 aperture of 2.0 lets in twice the light of nikon so it can take lower iso shots.

The IQ of the Olympus tough series is simply atrocious, so wide angle or not who cares? It's time they took the segment seriously. The whole market should move to 2/3" sensors at a minimum and off RAW.

Now a Sony RX200UW with 20-100 f/1.8-2.8 lens and 1" sensor would be sweet.

pocoloco: I am not so convinced a compact camera could not have captured that unique moment : http://www.dpreview.com/galleries/3225500706/photos/160652/turtle?inalbum=beneath-da-surface

The IQ from even the best UW compact today is frankly a joke. Still living with those woe 1/2.33" sensors, poor IQ ant any ISO and even out of water, but hopeless above ISO 400. All the bells and whistles but not the important stuff.

Hopefully Nikon has set a fire and will ignite this segment. Canon should have turned the EOS-M into the EOS-M(arine) as that's the only thing that might save it.

On Canon announces EOS M2 in Japan article (620 comments in total)
In reply to:

thx1138: Hugely disappointing and frankly embarrassing from Canon. The EOS M was at the bottom of the mirrorless pile along with the Nikon V, J series, but at least they have excellent AF speed.

So no DPAF, no EVF, no new lenses, same old sensor tech and battery life is an appalling 230 shots.

This is the camera equivalent of Windows 8.1, it might be better, but few people will care.

What's really telling is that they've abandoned the US market with this update. The EOS M sales were eterrible in USA and it looks like they're not pouring anymore money into that market. The mirrorless sell very well in Japan and Asia as a whole where the M2 will be available.

There are rumours of a much more advanced EOS M coming and new lenses, but I find it a strange approach to garner interest in your product by abandoning the market and then hoping the new camera will magically have a strong following.

On Nikon Df preview (2817 comments in total)
In reply to:

thx1138: Completely outclassed by the other sensors for resolution and only leads on per pixel noise, but of course with a lot less pixels that's nothing special. Upsample it to 24MP or downsample the others to 16MP and it loses out again.

Can't see why this didn't get the D610 sensor and then it make more sense and make it more future proof.

Sorry you have the misconception and are about the only person I've seen claim downsampling doesn't work. Ok maybe the D610 falls apart completely at very high ISO, but even as you say yourself it's fine to ISO6400, which would cover 90% of peoples use IMO. In this case downsampling gets you very close on noise and still leaves you with a bit more detail.

On High-end pocketable compacts 2013 roundup article (128 comments in total)
In reply to:

samfan: Let me put it this way. As advanced as Sony or Canon are, or as sympathetic as Fujifilm is, or as much as I like lots of other cameras...

The viewfinder, such as it is, on the LF1, gives it a million mile headstart against anything else in its class.

I will never, ever understand how can so many people shoot with their arms stretched, using cameras that are completely unfit for such a goal. I can make due with a positionable LCD (such as on my EX1), but fixed LCD? Never. Even though I have such a compact. It's just a terrible way to take pics (except macro/closeups).

I never liked Panasonic cameras, but recently it seems they're the only one that 'get it' in compacts.

Heck, if I want to carry a small pocket camera, I carry a FILM COMPACT just so I can have a viewfinder in a small camera. Maybe I'll consider such a Panasonic some day.

chadley_chad, I guess that's why Sony now offer an EVF option with the RX100II, since composing via the LCD is such a great idea.
