On article 2017 Roundup: Semi-Pro Interchangeable Lens Cameras (713 comments in total)
In reply to:

Magnar W: After working with photography for a long period, and now teaching photograpy, I don't care much about categories like "high end", "semi pro" etc. I have met photographers at all levels using different brands. From my point of view, photography is more about camera technique than camera model and system.

When buying into a system, I would not say: Buy the "best specs" or "best i test" or what your heroes use. I would rather ask to took closely into what their photography is about, and then go for a system that covers their needs. Many will find the emotional part the most important: Do I like the system, and will the system suit my needs for the future?

Cameras are tools that need to be operated with skills and knowledge exceeding shutter speed, aperture, ISO and autofocus settings to get results results that satisfies the photographer and the public, no matter if the goal is sharing pictures on Facebook, attending a camera club, making exhibitions, earning for a living, etc.

Indeed... this article makes no sense at all. It includes Leica M10 and Leica SL as "semi-pros", while by all accounts they are pro cameras, the best that Leica can do in the format. The Leica M system is completely pro, is it not?

Also, cameras like the Nikon D500 and Canon 7DMKII are often used by pros as complementary to their kit, what better definition than semi-pro is there? The 7D is often referred to as a "baby" 1DX, so...

It's called lens flare.

Dear Noah - you seem to be the irrelevant one.

biza43: Yes, I used it at the time and it worked fine for me. No need for it today.

"Sometimes there's more than one subject to select. Your eye is much quicker than your finger or any AF system to date."

Yes, we can all think about ways to trick the technology... with several subjects to select, your eye would also be all over the frame, with the eye_AF trying to keep up...

Of course the online world is not the best to see high quality photographic work. But there is no doubt that if one starts from the best capture medium (be it film or silica wafer), one has better chances of expressing one's vision. Ansel Adams also developed a signature method of image processing, that is for sure.

Because with mirrorless technology, we already have reliable face and eye continuous AF tracking. The technology has catch up and surpassed the eye-focus from the past.

G1Houston: How does it compare to the bokeh generated by iPhone 7-plus?

Someday digital camera should be able to *automatically* take a series of photos at different focal points, relative to the subject, and reassemble the images to allow post-adjustments to achieve the desirable bokeh. When that becomes a reality, these specially built (and pricy) lenses with lots of compromises will no longer be needed. Of course the key is to collect and process the images "automatically" that the camera can determine the two focal points between which the images should be acquired relative to the subject of interest, and then process the images quickly post-capture. In addition, there should be powerful software tools in and out of camera to allow users adjusting the bokeh and to pick the one we like. In the mean time, I look forward to Apple's next iPhone with an improved camera system to see what they can do with a smartphone.

"Compromises? Loss of light in low light, inaccurate and slow AF in low light, size, and price ($1500). These are not enough?"

So you have found out that this is specialty lens? Amazing insight...
now I can also say that the 85GM lens is compromised: worse bokeh, longer minimum focusing distance, heavy and expensive too. Are these not enough?

demaio: Take a look at image 32. I wouldn't say that rendering of such a 'busy' background is too smooth, and we're talking of a shot taken wide open. I would take my $500 50mm f/1.2 AI-S which gets me way better bokeh and is also good in low light any day instead of this 'one trick pony'.

Good for you. When you manage to have AF and OSS with your Nikon let me know.

Bombastic: Interesting addition to Sony's lens layout.
How does this compare to Nikon and Canon''s soft focus offerings? This one is much more expensive?

Nikon discontinued their two Defocus Control lenses, at 105 and 135mm.

Canon has long discontinued their 1987 135mm f2.8 smooth focus lens.

What lots of compromises? This lens is about as optically perfect as can be made today, at this price.

Want smoothed background: use T-5.6.

Want a bit more defined background: use T 6.3 - T 8.

With this lens you can opt to have smooth (T5.6 image) or more defined (T6.3) OOF highlights. Gives you both options.

The Batis, GM, etc, the normal lenses, only give you one option.

Thanks for the article, liked the photos very much. I just wonder how you will feel in a few months about the lens, once the novelty wears off:)

In reply to:

TN Args: "...continuous e-shutter shooting (anything above 5 fps) does drop the camera into 12-bit mode, so expect decreased dynamic range in Raws when shooting (electronic) bursts." -page 3, paragraph 2.

The internet forums are wailing with "bitter disappointment" and "deal-breaker" commentaries on this one point.

What do you mean, "expect"? Aren't you all making a mountain out of a molehill? After all, every current Olympus OM-D camera with its little 4/3 sensor and 12-bit raw files has a higher Landscape Score* on DxOMark than the Full Frame 14-bit Nikon D5.

So what is the practical effect, realistically stated, of what you call "expect a decrease"?

* from DxOMark, "Landscape Score is defined as the maximum dynamic range performance".

Yup, 12 bit is more than enough for photogs that shoot sports and action and have to quickly send their JPEG files for news agencies.

For mr izo: reviewers were invited to the launch event, and they had NDA on the photos they took. This was one week ago. Give the folks enough time to properly review the camera...

luben solev: Comparing Apples and Oranges perhaps?

After all, both the price and the intended usage of both cameras differs substantially.

Which is the point of the article, right? If it avoids the flood of "should I buy the A7 or A9" posts, I am all for it:)
