Sdaniella: Fujinon XF 1.5x.sensor.factor 18-135mm F/3.5-F/5.6 R LM OIS WR

Fujinon XF ff.equiv.fov 27mm-202mm F/5.3-F/8.4 ff.equiv.dof R LM OIS WR

ad=5.1mm wide to 24.1mm tele (aperture diameters)

Relative aperture a.k.a. f-stop is the only relevant measurement. Claiming otherwise shows total ignorance about optics.

On Nikon AF-S Nikkor 58mm f/1.4G review preview (414 comments in total)

I have shot portraits with this and Sigma ART 50mm, and while NIkkor is unique in its own way, I still choose the Sigma for out-of-this-world sharpness even full open.

It is also 60% cheaper...

Which shows that it is possible without Zeiss Otus price, with AF.

On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (544 comments in total)

Just shot my first assignment with Sigma 50mm f1.4 Art on Nikon D4: totally amazingly sharp full open. Accurate and fast AF also. It is a keeper! Next I have to play with D800e...

On SherpaFund raises money after Everest avalanche article (21 comments in total)
In reply to:

MikeFairbanks: They endure a lot to prepare for their climbers, so I hope a lot of money is raised for the families.

On a separate note, I don't like what happened to Everest. The climbing routes are covered in discarded oxygen tanks, tattered abandoned tents, human waste that doesn't decompose, and worst of all, over two hundred dead bodies, preserved forever (or until they are removed by avalanche or people).

It's a tragedy that they couldn't go home and it's a tragedy that they are still there. It's also a tragedy for one of the most beautiful pieces of nature in the world. Imagine if Crater Lake had 200 dead floating, preserved, on its surface each day. Not cool.

Most visible trash, oxygen tanks and ripped tents, is at South Col, a windswept pass at 8000m, site of camp IV. Only climbers go there and it is really not a photographic place, trash or no trash. There is no trash problem to make the place less photogenic. What comes to dead bodies they are listed under biodegradable waste in the climbing rules and there is no need to bring them down. Doing it would actually cause more damage than just leaving them there.

There is some old trash in the glacier, it will be ground there for about 500 years before it is spit out at the terminus. Not likely to be much left.

I have visited EBC 4 times since -85, last time in -09.

On SherpaFund raises money after Everest avalanche article (21 comments in total)

While losing the main breadwinner in any family is a disaster to all concerned, Sherpas are the wealthiest ethnic group in Nepal. A high altitude sherpa earns annually 10 to 20 times the national average. True poverty lies in the western Nepal, where no tourists and no relief funds go. Namche, the tourist hub of Khumbu, is per capita the wealthiest city in the whole country.

Something to think about also.

In reply to:

Thorgrem: Very nice to see big professional tele lenses which arent ugly white. Or does this one also comes in white?

Many nature photographers wrap camo tape on these. Why not white gaffer's tape if you are worried about to noonday sun.

In reply to:

LSE: two fluorite elements vs canon's just one. should be interested to see which comes out on top CA tests.

Just read somewhere that this new 400mm Nikkor has the best MTF chart at full open of any lens, ever.

We'll find out soon. Prices are going up considerably, Canon 200-400 was the first example, but almost all new pro lenses form Canikon have been more expensive than the ones they replace. Maybe that is because those companies are really pulling all the stops, and with super sharp sensors available (and coming soon?) they have to. That reflects in price.

On onOne Software's Perfect Effects 8 available for free article (117 comments in total)
In reply to:

robbo d: Was easy to download and looks like a cheapened version of Lightroom meets photoshop.
Some interesting features, but after a quick look through, I don't really like what I see, very noisy and tacky applications. Some are OK.
Not bad for a free offer, but I'm deleting it and sticking with LR5 & PSE.
Good for those looking for a free enhancer.

About overdoing: even if a particular filter is over-the-top, you can adjust it to your liking. Then, in PS, you can further diminish and blend the effect as it appears as a layer on the top of the original photo. So no worries there.

In reply to:

Bimbello: How does it compare to the NIK Collection which I am using?

Is it just some more useless effects or rather useful?

Certainly worth having, for free! Certainly there are many similar filters, but also slightly different ones. Besides OnOne has the ability to have several layers added at the same time.

I also have NIK, by the way.

I just used it on a dozen of D800e photographs for a glossy magazine. I did not see any noise, if results are tacky depends on how much I use or overuse the effects.

It is not a replacement for PS or LR, it is a plug-in package just like NIK. But free.

On Fujifilm XF 56mm F1.2 R real-world samples gallery article (272 comments in total)
In reply to:

Daniel from Bavaria: To all the moaners and naysayers:

I do photography for many, many years now. I still own a complete Canon FF system with quality glas.
I also own a Fuji X-System with some glas, as also the 1.2 56mm lens.

You see, plenty of experience and enough equipment to compare.
And in my humble opinion the 1.2 56mm lens is one of the finest lenses I've ever used. It's just a joy to use und the results are lovely. Period.

Cheers,
Daniel

P.S. Some pics taken with that lens are in my gallery

I have compared both 35mm f/1.4 and 56mm f/1.2 Fujinons to comparable respectable 50 and 85 mm lenses from Canon and Nikon (both f/1.4 and f/1.8 versions), and the Fujinons are sharper by far especially at full open. Sometimes unbelievably so, have to double check the EXIF to make sure they were actually used at full open.

On Leica T (Typ 701) First Impressions Review preview (2222 comments in total)
In reply to:

samfan: Sounds like a camera for the same people that believe Apple was the first to have a web browser and camera in the phone.

Now they can buy a Leica, believing it's the most advanced ILC.

Just from the control description, this contains features that p*ss me off royally on any camera: such as not being able to have both grid and live histogram at once and having exposure info on the display essentially cropping the preview image.

And that touchscreen also appears to be used as well as on the current smartphones, i.e. poorly. The whole screen just does things that would be achievable by 2 buttons and a 4-way controller. You can do much more with a touchscreen if you don't design only for the lowest common denominator with fat fingers. Which this camera apparently is.

It's no longer a "nice toy for the rich" like Leicas tend to be, this is a toy for the stupid who want to feel smart.

@ Tom C: "best camera in that class that money can buy". Which class it that? APS-C class maybe? There is no indication whatsoever that this the best camera in that class. I would rather think that it will be nowhere near "best" either in IQ or especially ergonomics in real shooting situations. I personally would much rather take two Fuji T-X1 instead...

It is a basic $400 mirror less modern camera in a $200 aluminum shell with smartphone touchscreen, and $2000 logo. Nothing more, nothing less.

On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (544 comments in total)
In reply to:

Mikael Risedal: Kudos to Sigma , almost there, best regards Otus

Bokeh = unsharp areas of the picture: often lenses which are not the sharpest have best bokeh. Like the new Nikkor 58mm f/1.4 which is the Bokeh King, but not nearly as sharp at full open as the new Sigma and Zeiss.

On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (544 comments in total)
In reply to:

Reactive: I just used this site's own lens comparison and came to an astonishing conclusion: stop down to f4 or smaller and you might as well buy Canon's 50mm f1.8. Try the comparison yourself. Above f4, the figures are near *identical* across the board, with just a slight barrel distortion on the Canon (easily correctable in software). So do I spend £850 on the 815g 100mm long Sigma, or spend £85 (yes 1/10 price) on the 130g 40mm long Canon? What could I do with the spare £765? New camera body? A new high-spec laptop to add a touch of sharpening to my Canon's images?

Your conclusion is not all that astonishing. All reasonable quality lenses are almost equal at mid-apertures and smaller, as the designing of a near-perfect lens at f/4 and smaller apertures is relatively easy, and at f/8 and smaller all lenses for 135 format are diffraction limited anyway. So it is true that all the commotion about the amazing image quality of these new Sigmas and Zeiss Otus refer only to large apertures of f/1.4 to 2.8 or so. If somebody wants to pay hundreds (Sigma) or even thousands of dollars (Otus) for near perfection at full open, let them. I am getting the Sigma because I do shoot quite a lot at full open or at large apertures and it has AF. Zeiss Otus is not for me, too expensive and manual focus only.

On Fujifilm X-T1 Review preview (564 comments in total)
In reply to:

bawbaw: comparing the raws of all the fuji marque bodies... there is nothing in here to justify going from the x-pro to this

How about not going from X-Pro1 to X-T1 but getting both? T-X1 is faster, much better with longer lenses which require EVF to work at all, etc, but X-Pro1 still has that certain feel I like with normal and wide-angle lenses. With 56 and 55-200mm lenses X-T1 is clearly better. That is why I have both (and X100s).

On Fujifilm X-T1 Review preview (564 comments in total)
In reply to:

ethwit: I have been using X100 for the last few years. I wish it focused better/quicker, I wished it had interchangeable lenses, etc. This camera ( X-T1) improves on all of the features of my X100, except.... the optical viewfinder. I find the electronic viewfinder does not come close to true optics. Not in the bright sun light. It's a a compromise. Thus, I will keep using my X100 until Fuji comes up with an X-T1 OVF. I have a feeling i will not have to wait very long.

Those without the money or real need always wait for the next model.

On Hands on with the Pentax 645Z article (648 comments in total)
In reply to:

Raist3d: If I was a Pro Landscape Photographer, as in selling big prints, etc. of landscapes and having a nice cash flow I would totally go for this.

I tried the first camera before this one and it is quite amazing. Pentax has a long history of medium format 645 film series, and this one supports all those lenses too.

"More pixels, better prints/files" does not hold true anymore. Many, if not most landscape photographs can be stitched from several frames, and carrying a smaller camera and doing stitching might produce just as good photographs, and maybe more of them as the system would be easier to carry around and take to places where bigger/heavier cameras can not go.

This new Pentax is undoubtedly a great camera, but considering cost, size, weight etc of the system it might not be ideal for all modern style landscape photography. FF cameras also have new state-of-the-art lenses like Zeiss Otus and Sigma Art series, which are better than anything available for MF, which levels the playing field also.
