Sugarsnapphotos: Hopefully this news will bring down prices for used Leica lenses on ebay.

In about 50 years . . . then you won't necessarily care.

It's not the drones that can be dangerous and harmful, but rather the drone operators that can be dangerous and harmful when they do stupid things.

Nice creativity though combining new and shiny tech with old analogue tech.

Lan: Executive summary: Centre sharp, but corners soft.

High levels of astigamatism/coma appear to be the reason for the relatively poor showing at the corners; so this is not the lens of choice for astrophotography.

That said the A7R2 is a harsh test for any lens. Based on my experiences on a 5D2, I suspect the Samyang 14mm f2.8 might be a better option, but I haven't tried it on an A7R2...

Or, it's a perfect 16mm/4.5 after you crop those sometimes soft, but extreme corners out of the image.

cdembrey: The new Voigtlander 15/4.5 III Aspherical Super Wide Heliar is a telephoto compared to the Voigtlander 10/5.6 Heliar-Hyper Wide. NO Interest in Sony FE camera or lenses, I'm waiting for the Leica M-Mount version.

Yes, but I don't think anyone knows how this lens will perform - especially in the corners that the 15/4.5 -III seems to have problems with on many copies. You might have to crop it back down to 15mm equivalent FOV . . . hopefully not.

The other thing that this lens excels at is flare/ghosting control. It's capable of making great sun stars when stopped down just a bit.

That and it's so darned small/light compared to some of the faster UWA alternatives.

jhinkey: The question is how good of a copy does the author have?
Over on FM there is a great thread that shows there is a huge variation in these lenses regarding the corner softness - some of the new E-mount versions have very very poor corners while a few have very very good corners.

I have the -III VM version with very very good corners and a few people have a new E mount version with very very good corners.

So this lens, if you can find a good copy, does very well in the corners. Not pin sharp, but sharp enough for sure. I can't quite tell if the author has one of the good copies or one of the bad copies.

Yep. And the killer is those corners don't change at all upon stopping down - if you get a "good" copy the corners are good no matter what while if you get a "bad" copy the corners are really bad and they stay that way even at f/11.
As I said I seemed to have lucked out with my M-mount -III copy to get pretty decent corners and am putting off trying to get an E-mount version (for my A7RII) until this high copy-to-copy variation has been resolved.

Having been a climber for quite a few years now I immediately distrust any outdoor gear that claims to be "waterproof" unless it's rubber coated on the outside and/or inside. Sounds good, looks good, but highly doubt it.

MikeDPR: Nice shots overall.
But were the lady's feet okay after the hike? Her shoes look a bit too lightweight for the job. Ouch.

Nah, it's a fallacy that one must use heavy-weight and bulky footwear for such things - I long ago lost the hiking boots and went the light weight route - not quite as light weight as what she's wearing, but not far from it. You hike a lot your feet, ankles, etc. get in shape and you can get away with such footwear, especially on dry trails.

I can see the attraction, but having spent a lot of time using the RX10-II for technical work (high speed video on the cheap) I would not want to get caught in a rainstorm, sweat a lot on it while hiking, get it dusty/dirty as the build quality is just not there for the rigors that hiking in the PNW put on a camera.

Need to give that hike a try!

On article Making a splash: Nikon D500 real-world sample gallery (228 comments in total)

Nice! You managed to catch the ubiquitous old motor home that is constantly parked on Harbor Avenue along that stretch - one of many mobile homeless homes in Seattle that have become part of the urban landscape.

Although these pictures are great and all, really did anyone expect anything but great image quality from such a well refined camera that is the latest in an evolution from previous models from Nikon. Never quite sure how these images would sway anyone to buy the D500 over something else, especially since it's their advanced flagship DX body that a pro would know all about anyways.

Nice images though.

jhinkey: Great. I can sleep better at night now.
But seriously there are at least a 1/2 dozen other things that could be improved/fixed via firmware on the A7RII alone - where are those?

How so? You don't agree with my list?
I don't see the A7RII on your gear list . . .

By Thematic (17 min ago)

and considering his current gear list shows he doesn't even own the camera - jhinkey the keyboard jockey strikes again with a negative comment.

Strikes again? Really. Nothing wrong with a non-positive (negative) comment.

My point is that there are plenty of things that could and should be fixed via a firmware update with this excellent photographic tool, but we get this one instead. Sure there are folks who care about this firmware update from Sony, but I bet there are far more users like me that have their own long list of things that need improvement that would really make this great tool shine even brighter and be even more useful.

Ah, my gear list is not up to date.
I've owned the A7RII since right after it hit the shelves. Owned the A7R before that. Been using it along side my D800 for quite a while.
You want a firmware upgrade list smart a**es:
- Adjustable EVF/LCD switching sensitivity
- Put the focal length used in IBIS when using a non-CPU lens into the EXIF
- Use the IBIS focal length to adjust the min shutter speed when in A-priority mode - when using a non-CPU lens
- Leave the histogram active in the display when adjusting ISO, shutter speed, etc. Why can't we see the histogram change as you change a setting instead of guessing at how much the histogram will shift as you adjust things?
- 14 bit mode with electronic shutter
- 14 bit mode when using LENR
- Faster start-up - the A7RII is waaay better than the A7R, but still slow compared to my m43 mirrorless cameras
- Why do I have to turn the camera off after using the dust removal function?

There, 8 things w/o working hard at it!

Nice article. Hopefully the full image set will be available for public viewing sometime soon.

In reply to:

jhinkey: Still a kludge of an approach since distance matters a lot with many lenses. Also, what about manual focus lenses that have CPUs where you want to use the green dot in the viewfinder to confirm accurate focus - that indicator needs major upgrades to really be useful.

Also, could this not be added to older models via a firmware upgrade? Doubt that will happen.

Yep to the above. On-sensor PDAF is the future such that many of the inaccuracies in lens focusing can be gotten rid of. On-sensor PDAF has its own issues, but these are becoming less and less as the technology improves.
