A big fat YES to the 40-150/4. The 2.8 version, while being a great lens, is large and expensive (relatively speaking). The 40-150R is a cheap kit lens, though not bad optically. The f/4 version, would make a nice constant aperture version that would be reasonably compact and, as with Olympus pro lenses, deliver nice image quality throughout the zoom range and have weather resistance.

Simon97: Nice rendering lens. Sharp and fringe free. No decentering. Canon is probably the only company not foisting garbage misaligned optics on their customers these days. Note: I don't shoot canon. I call it as I see it.

All lenses have a manufacturing tolerance. Decentering can be detected on optical benches that Roger has. It may not be bad enough to be an issue in real world use. I just found Canon's lenses to have the least problems from the lenses I've used. I often see lenses with bad enough alignment that I'm surprised that they are released for sale.

Also, like I said, I don't shoot Canon. I use micro 4/3rds and they do have an issue with decentered lenses in my experience and Roger of Lensrentals mentioned that. So why don't I switch to Canon? I'm not interested in spending $$ and I'm quite happy with what I have now. I weeded out the bad lenses and have a good set now.

Good lens but this sample is decentered. Several photos show softness on the right side. Kind of an astigmatic effect where horizontal lines are blurred more. A good copy of this lens should be great as color fringing seems well controlled.

On article Fujifilm GFX 50S II review (523 comments in total)

Looking at the RAW image comparisons, I can see only a marginal advantage to the GFX 50 compared to most FF cameras. I also notice that FF lens selection is larger and with faster glass which can more nullify the differences. The 100 MP MF camera makes more sense given the resolution advantage. As for this 50MP MF camera, it doesn't seem worth it to me.

Have we met the end of the blurry UFO photo?

Does Pentax not do chromatic aberration removal to jpegs?

Anyway, if you shoot raw and convert with Rawtherapee, Its auto chromatic aberration removal tool is amazing for the fringing near the edges. Be sure to turn off the aberration correction based on lens data so they don't clash.

This lens looks very sharp and without much of the annoying fringing (except in a couple cases). I wish it would have gone to 60mm, but there must be compromises when making a constant f/1.7 zoom.

I'm not so crazy about the jpeg engine in this camera. Soft-ish look and details are smoothed over. Tweaking the sharpening and NR setting should help. Raw processing shows you can do far better.

The low angle of the Petrel shot makes it look terrifying. Like a giant creature from the past. Not something I'd hang on the wall, but good documentation of the natural world.

It seems to be able to turn unrecognizable blobs of the smaller text into something readable but it can't make detail where there was none to begin with, such as the hatch patterns in the etching. A higher res modern camera could see those patterns in the first place. Also removes color moire as well. Impressive for what it can do, but it can't work miracles.

I worked in IT for a small company with around 100 PCs. One thing I noticed is after around the year 2000, the number of HDD failures declined dramatically. In the early 90's, drive failures were the most common failure. From 1995 to 2000 it was reduced but still one of the most common failures.

After that it was memory and power supplies.
I'm not counting keyboards, mice, CD drives and floppy drives (FDDs left in the 90's) but they were common to replace.

I don't know how many computers I went through after my 18 year stent, but Processor and motherboards rarely failed. I remember only one occurrence.

After 2006, I left the my IT career and have been self employed, so no experience from that point.

Reminds me of a colorful transparent version of the planet killer from Star Trek.

I'd like to see MFT get back to what it is good at, small cameras and lenses. Sure there can be the fast lenses and larger bodies for the up market, but I'd like a GM1 sized camera with a better grip and also expand on the already good lot of tiny primes they have.

This comment is why I wish there was a thumbs down button.

Mateus1: Z7II high iso looks best, second place is for R5, next S1R and last A1.

Not sure why, but it seems Sony can't take the best from its own sensor.

In the past it was a reduction of noise in the latest sensor that photographers seemed most interested in. I recall the fanfare from Sony's 16mp APSC sensor years ago with its significantly reduced noise from the previous generation sensors. Perhaps all the latest tech desired in the current sensors makes getting the lowest noise not possible. I know a lot of PDAF sites all over the sensor certainly doesn't help the matter.

Simon97: When I view at 100% and use the mouse to drag the image around, it is not smooth motion anymore. Something with my computer or DPR changed. Does this happen with you?

Nice lens, BTW.

After rebooting, same problem. 2gb of 8 in use. Firefox is the only app running and only process using CPU time. Interesting finding though: CPU usage at 0 sitting at the home page of DPR, still 0 after opening the gallery but after going to 100% view and moving around, CPU goes to 10% and hovers there even when not moving the image. DPR appears to be running code the uses the CPU at 100% view. Closing the gallery drops the CPU back to 0. This started two or three weeks ago.

The image reminds me of the background to the "Mona Lisa" with the twisting river and jagged peaks.
