Color saturation is the one area where my A50/2.8 does not shine, but with digital processing that matters little.

I am very impressed with my A50/2.8. It's likely the sharpest lens for Pentax I have. The lens is well-built. I use it with a gutted 2x tele-convertor when I want more magnification. It's the 50mm I use unless I want shallow DoF.

For me, it's a compelling scene that gets my photographic passions going. Many photogs are able to make great images of whatever is around, but I've not gotten there yet. You can check out my landscapes here: TOM CIVILETTI?s albums | Flickr

Set 2: #1 is technically the best. The blur of #2 may be an artistic improvement, though.

Set 3: all have problems. #1 is best in the foreground, but the sky is more overexposed and too green. #2 is too yellow. #3 is too blue.

#1 - more detail in shadows and good color balance.

I was quite disappointed with my landscape work for a few years. The process takes time with mere humans. It's helpful to shoot when the sun is low, as that increases modeling and atmospherics.

Good landscape photography requires competent technique and the ability to see photographically. Great landscape photography requires seeing photographically in your own way.

A long lens will also cause less spatial distortion, as the edges of the artwork will be approximately the same distance from the lens optical center as the center of the artwork.

I carried a 55mm, 90mm, and 165mm with the 6X7. A 45mm later replaced the 55mm. 165mm is not very long on that format.

Use manual focus. Set the lens for the distance you want to your subject and expose when the fireflies at close to that distance.

Of course B&H would not claim it is moving to screw workers. As with most disputes, both sides try to make themselves look good.

Support B&H workers

B&H Photo workers in Brooklyn faced horrific safety conditions for years. They fought back, organized for over a year, and overwhelmingly voted to form a union with United Steelworkers in November 2015 -- with crucial support from B&H Photo costumers -- thousands from the photo, video, art, music, and labor communities.

Now the company threatens to relocate almost 330 jobs 75 miles away, making it impossible for the workers to commute to work.

Moving hundreds of jobs away from New York City is a betrayal to working families, New Yorkers, and the workers who courageously fought to be treated with respect and dignity. And that ain't right!

Resolution testing of the FA50/2.8 showed the highest scores at f8. It surprises me that the current version would peak two stops earlier.

Pentax A 24mm 2.8 vs Sigma 24mm 2.8

There was a shootout online the compared 24mm lens converted to use on Canon. The Sigma made it farther than the Pentax. I have one of the manual focus Sigma's 24/2.8. It is a decent lens. The color is different than Pentax, but that can be tweaked in PP.

The Samyang 14mm and sharpness....

Ultra-wide angle lenses usually have considerable curvature of the focal plane, so you need to focus on one spot of the chart, the same spot in the same part of the frame for each lens tested. Different focal lengths complicate that, but you should be able to get worthwhile information from the process.

---------- Post added 01-22-17 at 06:58 PM ----------



I often zone focus my sigma 8-16. There is not much to see unless I use live view, which is not always desirable.

So we are talking about bokeh, not the characteristics of in-focus areas of an image?

---------- Post added 01-22-17 at 01:37 PM ----------




Perhaps my eyes are not up to snuff. I do not see what makes that image dreamy. Would the same scene in the same lighting taken through a different lens be undreamy? It seems to me that any characteristic that a lens lends an image should be able to be described using measurable optical terms like resolution, contrast, micro-contrast, diffusion, circle of confusion, etc.

Yes. What is the meaning of smoothness in the images produced by a lens beyond smearing?

Not everything, just this, which makes no sense to me at this point.

What do you get from a smooth or creamy lens that you could not get with PP noise reduction? when I turn up noise reduction, my images get very smooth, not that I find that an improvement.

The Samyang 14/2.8 is not small or light, but it is inexpensive and fast, and has great image quality.

Older wide angle lenses often work poorly on digital because of the low angle with which light hits the sensor edges.
