Hugo808: When I looked ta the picture my first thought was that the lens hood looked way too long. How clever and practical is that solution!

Olympus was using it long before this came out. My 35-70 OM 3.6 works the same way.

AngularJS: Amazing samples! Never messed with TS lens before, but would like to try now. Any suggestions to a beginner? As a Canon shooter I can get either 17 or 24, not sure which to choose :)

I have both, and am a sony shooter as well. The 24 is a simply fantastic lens - distortion free as far as I can tell, and sharp. the focal length is useful for many situations - it is wide, but still give a realistic interpretation of the space. You can always use the shift function to create a wider pano.

The 17 is great fro dramatic emphasis, and tight spaces - as dbo pointed out, it has a bulb glass front, and it's a beautiful piece of glass, but it will see damage. I see this lense as a luxury - I use it in specific situations, but the 24 is my interior go to.

I rented from lens rentals - and then bought. You can test the lens, they deduct the rental from the final cost (which is a fair price used), and they're great people to do business with.

In reply to:

obsolescence: It would be interesting to see a comparison of T-S lens-shifted vs. software-corrected images -- this lens vs. Nikon 14-24mm.

To some degree - especially with a hi rez sensor, software correction works well. Even for this T/S you're probably going to have to do some distortion correction and minor perspective correction. But if you're really shifting, the ability to accurately see the final composition is great.

Other uses - shifting to avoid reflections, using shift to create a panorama - these are specific to the t/s lens.

And of course, with tilt , you can modify the field of focus to get sharp results that would simple be impossible with a standard lens.

It's all CGI. Everyone knows that in real life, a giant alien robot, forged in the fires of hades, would unfurl out of the steam and fire to destroy civilization.

In reply to:

DavidsfotosDotCom: Seeky, thanks but page 5 only uses the word "Dynamic Range" (DR) but fails to state what the DR is! Is the DR 14 bit or 16 bit or what.
Does Nikon's FF still have the best FF DR?

Isn't DR measured in EV?

Mike Davis: With 8256x6192 pixels on a 43.8x32.9mm sensor, I've calculated a pixel density of 188.4 pixels/mm, which falls below my long-held opinion that, ideally, sensors should never exceed a maximum of 200 pixels/mm, lest the cameras suffer an inadequate range of f-Numbers at which diffraction will support true subject detail resolution of 5 lp/mm (in a non-resampled, uncropped, 360 dpi final print from a CMOS sensor, where the RGBG Bayer algorithm and AA filter will reduce a pixel count-implied resolution by 30%), to support a viewing distance as close as 25cm (9.84 inches).

Maybe overthining. To the last point - they're all using Sony sensors.

On article F is for '4th': Hands-on with Fujifilm X100F (422 comments in total)
In reply to:

samhain: Talk about milking a camera line.
Fuji managed to take one of the most loved digital cameras ever made and turn it into something sad.
For Fuji to still be using the same long in the tooth- soft wide open lens, no stabilization, no weatherproofing, same clunky manual focus, the same Xtrans sensors that gives owners a workflow headache & has them jumping at every new raw processor to hit the market in hopes of finally finding one that can figure out the xtrans files, etc etc... It just makes me shake my head.
There's a reason the new medium format doesn't have An Xtrans sensor.

If forced to choose, I'd still pick the first x100 over all the other models (yes, I've owned and used them). Even if they were the same price.
I hate to be so harsh towards Fuji, but... These incremental updates are getting old.

Look at the specs on the rumored coming Sony RX5.
THAT is what the specs for the Fuji x100f should be, especially in 2017.

@Mike f4 black My guess- sony sensor.

In reply to:

Mark Turney: Well, we live in an analog universe so it's no wonder to me why digital tends to "feel" wrong. But I'm also not sure that going back to a old technology is the answer, especially considering that Kodak digitizes the film from what I understand, looping us right back to that which we seek to avoid.

Anyway .... just some food for thought 💭

Wow - so people don't understand the difference between analog and digital - fascinating.

Sensors are analog devices - no matter how fancy the terminology used to say otherwise. Or are we really going to get into the wave/particle duality.

Polytropia: To all the haters:

My grandfather shot Kodachrome Super 8 & also black and white movies of his kids. Those movies look as good today as they did when they were shot.

How good will all your digital videos look in 65 years from now? Will they even exist?

I can shoot some film and put it in an archival box with a projector, and know it will be viewable in 100 years as long as there is a source of electricity. I'm not sure you can say the same thing about any digital information formats.

And honestly how much more often do you really want to watch such videos? lol.

Also, protip: clouds evaporate.

The only archival color film was kodachrome - it used non photosensitive dyes in its processing. Ektachrome will indeed fade to a magenta hue.

probert500: ... or you could up your iso to 200 or 400, get a cheaper lens and spend the savings on hookers and coke.

@Curtis Morgan In the film days, changing ISO was tricky, however in this modern wonderful world, you will find a dial assigned to iso (RTFM). Turn it, it's fun!!

probert500: Dunno - an inexpensive fluid head will do this, and if you want smooth starts and stops, put a rubber-band on the handle and pull from there. Please send 10% of the money I just saved you to my rubber-band smooth motion kickstarter.

It's not rocket science - set the friction on your fluid head and use a flexible band to avoid abrupt starts and stops.

aris14: The Foveon sensor produced images offer to user an easy, practically lossless and quite reliable interpolation of 250% far better than any other sensor. Great sensor for items with delicate texture and generally for studio work.

@netmage Rent one, try it, and get back to us.

Be careful when tying your shoe-laces - it's a dangerous world out there.

Mateus1: Natural rendering of images and the colour reminds me image rendering of film era... I heve never seen this in digital CMOS era. H1D would be my first digital cam for landscape... if my wife would be a Santa ;-)
You know where I would take it with these 3 Hassy lenses first?
To China, to shot its beautiful national parks. Oh boy, one year trip with X1D!

Gotta say, it's probably the same sensor, just a bit larger. Larger makes a difference but probably not much. PP, and how you do it, is probably key at this level of technical sophistication.

Take a look at the a7r and a7r2 - super sweet. The original 5d also had a beautiful look, although 12mpx seems long ago.
