On a photo in the Sigma 18-35mm F1.8 DC HSM (Canon) Preview Samples sample gallery (1 comment in total)

Interesting shot. The extreme corner sharpness of the lens wide open outperforms the sensor introduced reduced resolution of 1000 ISO. So not good to test lens performance, but indeed excellent to show real world application. And the fact that this lens does outperform the sensor at 1000 ISO even in extreme corners is still impressing me. Also good bokeh in the transition area also considering it is a difficult subject. I am a low light freak shooting many of my pics at f/2 and I can see nothing where this lens is worse than my beloved prime. Again, truly impressive.

Once again, amazing sharpness wide open in corner to almost extreme corner. Lovely bokeh with even with critical highlight subjects. Pretty darn amazing performance.

A wonderful Photo!

Pattern in the table shows that corner sharpness of the lens is great, even wide open. Bokeh is lovely even with difficult bright highlights, subjects focus is on the left eye and every hair on that eye is rendered perfectly. The critical transition area to the right eye has a beautiful bokeh. Wonderful lens.

And it is great photo which is fun to look at. Nice atmosphere and composition.

Thanks so much for!

Excellent sample pic to show regular low light use! And astounding performance of the lens! Very impressive indeed.

@ Richard: Excellent sample image! Add some post processing and you have fine art and a great lens evaluation :-)

And i am really, really impressed with this lens. Object close to corner at f/1.8 and still very sharp considering open aperture. The charismatic aberrations can be cleaned up in post processing which will increase the perceived sharpness even more.

There are some very bright highlights and they show no any purple fringing. It is possible this thing is better than my 35 mm AL f/2. Really impressive!

waitformee: i noticed that dpreview say that this is a preproduction copy and quality is not that good. In this case, why give a preview or bad quality images?

This image suggest that the quality of images this lens can produce is already impressive!

deleted_081301: "Swedish camera manufacturer Hasselblad is finally shipping the 'Lunar'."

Hasselblad LONG AGO ceased to Manufacture Cameras... and long ago ceased to be SWEDISH .....Most of thier Cameras are made in Japan by Fuji as are the lenses for them

Now they are rebadging SONY's with a wood Veneer

@ MichaelKJ
I do not see how you need a camera engineer to add ornaments to a finished camera product?

Dapple 101: I think Hasselblad are to be commended. This is the first time that I can recall the DPR comments section showing anything like a consensus.

@ Dapple 101: You made me smile. Thanks!

In reply to:

scunning14: Shawn can answer this if he wants, but I just wanted to add this to the conversation. The d7100 is obviously one of the k5II's main competitors. How is it possible that the d7100 scores a 13/14 for value while the k5II scores a 10/14? The k5II is currently $800 while the d7100 is $1200. That is 2/3 the price! Also the d7100 scores a 9/14 for performance while the k5II scores a 7/14, yet the K5II performs better in low light, has a faster burst, and a much larger shot buffer. I am not saying that the k5II is the better camera, but it seems like these two categories should be a little closer.

Here is a more detailed price comparison.

The sweet spot indeed is K5II for 800 USD versus D7100 for 1200 USD. In my experience the in body shake reduction more than offsets in image quality the jump from 16 MP to 24 MP. Especially when considering that most lenses in the Nikon product line do not resolve even close to 24 MP ( I am suspecting same goes in Pentax lens line, but good they do not have the 24 MP sensor :-) )

All prices in USD for Body without lens:
BH Photo Video:
* 7100: 1200 USD
* K5IIs: 1100 USD
* K5II: 1000 USD

Amazon:
* 7100: 1200 USD
* K5IIs: 1000 USD
* K5II: 800 USD

@ scunning 14. Thank you for bringing this to our attention. Especially considering that dpreview stresses scoring is done in comparison to nowadays available competition and nowadays pricing!

taktak91: Unless Nikon shows up with a D300(s) replacement soon, I might purchase this one.

@ rtogog: Indeed. Thanks for bringing it up

@taktak91:
Both brands have very strong lenses. Pentax primes are smaller, but mostly use slotted drive AF, which creates a moderate degree of noise. Nikon primes are significantly bigger and mostly use completely silent "Silent Wave" AF. The best place to compare lenses across system is: http://www.photozone.de/

SeeRoy: Good to know that by adding perspective correction we'll now be seeing far more top-heavy buildings in holiday snaps.

How is this cynical comment helping ? Do you want to motivate Adobe to take this useful feature out ? Do you want to discourage new photographer to use this nice tool to clean up their pics? What is going through your mind to make a good thing sour for others ?

Rick Knepper: Let me guess (before I read the article): he used an iphone.

He used Canon 5D MKIII, 16-35 f/2.8L II lens ( L-glass), Lee Neutral Density Filter and a Tripod. Quite very professional setup. Your comment to me appears quite unprofessional indeed. Make a negative comment about the Article based on a false assumption. Reading the Article would have set you straight already!

@ turmus
A breathtakingly beautiful shot. If you did do post-processing, then you are a gifted artist, as I can see none of it. But I do feel this amazing atmosphere you created! If I look at this image long enough, I am there. Congratulations to your well deserved win!

Gasman66: It's so obviously manipulated in post processing that what could've been an ethereal, haunting image has been spoiled for me I'm afraid.

@ Gasmann66
Your comment made me interested in your work which appeared to be better than even this great image. So I looked at your profile but sadly found no challenge entry of yours nor a single image in Galleries. I strongly feel that people who make derogative comments should at least be able to back them up by excellent work.

I now need to look longer at this image ( with to me excellent post processing ) to recover from you comment, which kind of spoiled it for me, for a moment at least.
