On photo Seattle I5 in the Your City - Highways challenge (24 comments in total)

A composition to enjoy, with wonderful perspective, linear guiding, moment, colors, whatever! Look at how the row of the clouds in the sky correspond to the row of the cars on the highway!

On article Nine new lens adapters announced for the Fujifilm GFX (90 comments in total)
In reply to:

tkbslc: Given that 24x36mm film has a 43.3mm imaging circle, you could get considerable extra real estate with different aspect ratios and still staying inside the native imaging circle.

2:1 crop would be 19.3x38.7mm sensor area (vs 18x36mm crop)
16:9 crop = 21.2x37.7mm sensor area (vs 20.2 x 36mm FF crop)
4:5 crop = 27x33.8mm (vs 24x30mm FF crop)
3:4 crop = 26x34.5mm (vs 24x31.9mm crop)
1:1 crop = 30.6x30.6 (vs 24x24 FF crop)
(numbers rounded)

And given that you'd likely be able to oversize crop at least a little on most lenses, you'll probably go a bit farther. If you planned to shoot everything at 2:3, then you'd be gaining little if anything on the larger sensor. but anything else, you'll have a lot more data to work with.

If you like to shoot 1:1, then a ff lens at 30.5x30.5 is only a 1.08x crop factor from the native GFX cropped to 1:1. And I'm betting the vast majority of lenses could tolerate 8% overcrop farily well, leaving that at full GFX sensor height.

What about adapting ff shift lenses (such as Nikkor PC35 / PC28)? Their image circle is certainly big enough to cover the whole GFX sensor, but maybe because of the lens' build construction only 24x36mm crops are viewable.

Maybe each lens needs its own dedicated curved sensor. So, what about making a dedicated curved sensor part of each interchangeable lens? After a few years you could screw the sensor out of your lens and screw an improved one in. Maybe the sensor has to be combined with the processor.

I don't know if that idea is worth to be realised and if it is technically feasible.

Yeah, they were standing in a snipers line of fire and didn't move to get out of it? Is that credible?

On article Comparison Review: Sony FE 50mm F1.4 ZA vs 55mm F1.8 ZA (261 comments in total)

Put the widget upon a roof in the foreground: Here the Planar 50mm is better than the 55mm lens; both lenses are on a par not before f4! In the background, though, it's the 55mm that's always ahead.

This makes me wonder if and to what extent the sharpness results here might be affected by distance settings which weren't the same at both lenses.

BTW, these lenses vary a lot as to their weight which IMO indicates what they are made for: The Planar 50mm is rather a specialist for portraiture, fashion, studio works, and the 55mm is rather an all-rounder.

Marty4650: The camera seems OK, but the most impressive thing is Carey Rose's skill as a photographer. He has a great sense of composition.

This is why we gearheads prefer cold blooded test shots of color charts, wine bottles, and coins and currency for pixel peeping!

Can't agree more!
I'm astonished to see what a capable photographer can do with this small Sony device.

On photo From Maroon to Yellow in the Fall colour challenge (14 comments in total)

I can't judge whether the criticisms posted here are justified, because I'm not competent when it comes to post processing. In my eye most of the entries are overprocessed. It seems to be a common phenomenon to oversaturate colors and exaggerate dynamic range. Everybody wants to stand out of the crowd, and software makes it easy to pimp photos.

IMO, the winner's photo isn't perfect but it's a well done composition with the clouds corresponding to the mountains. However, many contestants could have made #1 as well. Nevertheless congratulations to the photographer!

There's something wrong with the details in the gallery: The photographer used aperture f/2,8 with the Vario 12-60 mm F 3,5-5,6 (23/52, 28/52, 44/52 . . . )!

Mikael Risedal: The Sony lens does not look as been properly centered; look at left and right
take another example of the lens for test

Yes, the Sony lens seems to be decentered; resolution near the right-hand edge drops a lot.

Furthermore, the review doesn't consider how both lenses perform with bright light sources in the frame.

In reply to:

ThatCamFan: I went to a meeting Sony had in Iceland a few months ago, they introduced lenses & some sony bodies.
They claimed "our new lenses are so perfect that they dont have any onion rings unlike ""all"" other lenses" Basicly they're claim and they talked for 2 HOURS about how they had superior lenses and how there were no onion rings, they made sure to beat every point into people including the onion rings not existing.

It was 4 hours of talking that could be a 10 minute thing because they hammered the same claims OVER and OVER about the cameras and lenses, half the room had left before they were done talking before we got to test the gear because everyone had gotten annoyed that they wasted everyones time.

I managed to get onion rings right away with they're lenses & cant say I am impressed. I demanded to test it with uncompressed & full res which makes a huge file but yea.

I think they had it on different settings which would mask the onion ring effect. My faith in Sony is gone sadly.

Panasonic were the first. They said to be eliminating (or reducing?) those onion-rings in bokeh by preparing the relevant aspherical lens elements; since it's handwork it's costly and reserved for pricey lenses. Not much later Sony declared they had found a way to let a machine do that. Therefore you might expect the 55mm and other high quality lenses will get improved in the said sense.

Taking price and weight into account I can't see why anyone should prefer buying this 50 mm lens.

I guess it's a lens for studio works, maybe optimized for short distance shooting.

IMO Sony should take more care of quality control in lens production (rather than designing any new lenses there's no need for). There's much complaining about Sony lenses to be decentered. If Sony want their brand name stand for high optical performance, they must deliver!

On article Faster flagship: Hands-on with the Fujifilm X-T2 (121 comments in total)

There's a lot of high-quality lenses in the Fujifilm system and the new 24mp sensor lets them shine. The more I hope for a camera that suits me. I'm a left-eye shooter and I'd like to have a camera that allows to attach an optional tilting EVF (with high resolution).

On article CP+ 2016: Nikon shows off new D5, D500 and DL compacts (114 comments in total)

The lens of the 24-85 DL should have a screw-in thread for filters, lens hood etc.!

I appreciate especially the option for a tilting EVF; it's such a helpful accessory (and essential for the wide-angle model)! Moreover it indicates that Nikon aim at enthusiasts and 'serious' photographers with their new DL compacts. And this gives hope that the lenses deliver decent IQ without too much deterioration from image center to the corners (as a result from keeping the lens small enough for a compact).

Yes, it's likely bringing a gift; that's what I think the cat is doing there. Cats do this (mostly with mice), when they want to please a loved one.

'Thanks Barney for sharing your experience with the RX1R II!

I agree with him in many respects as to this camera's aesthetics, the EVF, tilting rear screen, manual controls, a 35mm lens being versatile etc.. And yes, a stabilizer is to be desired (as is dust and weather sealing, for this compact isn't designed for studio works).

Now my questions: Some of the pictures Barney has made show a lot of noise - not only at ISO 6400 but also at ISO 400 (steel bridge after dark). At ISO 400!? I really don't know what to think of it! And as to the dog photo: Am I right that the CA in the trees is easy to fix?

As to focusing Barney speaks about the AF performance. But what about MF with the RX1R II? Is MF a convenient way to go? (In the wide angle range I'd always prefer MF)

Finally: Couldn't an A7 II with a 35mm lens attached be a good alternative to the compact (with the option for changing the lens)?

I know, of course, the RX1R II is a tempting thing indeed!

mediasorcerer: this is a subjective opinion based on personal observation and use, however, im finding the 5 axis i.s. in my sony tends to make some photos have a doppelganger outline around the edges of foreground subject matter and i now dont use it much at all even handheld in the evening because of this aftereffect i have noticed in arw files onscreen.
i think images are sharper without out it, just have to develop the skill of holding the camera very still-technique.
It tends to show up even more when using editing effects like contrast etc.
its not as handy as you would think, maybe it works better when there is slightly more movement rather than less, ie if you are holding the cam very still the ibis creates the effect, thats all i can think of, but its there for sure.

Do Sony (and other camera makers) know of the issue with IBIS you're describing here? Are you sure it's the 5-axis i.s. that's causing the 'doppelganger outline' in your images? Or does the stabilization system automatically stop '...if you are holding the cam very still ...'? In any case your experience with Sony's 5-axis i.s. needs to be researched.

Cal22: 'Sadly ...there is no in-body stabiization!' That's right! I don't understand Sony: A camera with an image resolution that high should have built-in stabilization; it's a must!

Not any leaf shutter is guarantee for a smooth shutter release. But this is not my point: A handheld camera, small and lightweight, providing high image resolution of 42MP requires image stabilization to help the photographer avoid blurred images at shutter speeds of 1/30sec, 1/60sec (and maybe even at 1/125sec). Whoever purchases this promising camera doesn't want to photograph with high ISOs most of the time or use it on a tripod.

It's a fine camera, indeed, but I'm afraid there's a dealbreaker in it. Hopefully the Dpreview-team will be telling us more about my concern in their upcoming review.
