On article Sony 'striping': here's the fix (653 comments in total)

How large do you have to print to see that?
I have a feeling printer inks will blur that out. I usually have printing head or streak problems and ink diffusion issues that would let me never see this "problem".

Finally a full frame camera is released. I print 8x10 so this is the first full frame camera to become available.
I also strongly disagree with Rishi's initial comment. If you want higher resolution, you do not go up in sensor size.
You spend more for larger sensors to get better dynamic range, more subject separation and higher colour fidelity.
Higher resolution is not on my list. If you want higher resolution, buy a Sigma camera. The SD1m will still give you incredible resolution today.

This feature is exactly what I expected. Badically photoacute in camera. I may be wrong but I think photoacute was first, way before cell phone apps that I didn't even know existed and will have to look up.
Too bad photoacute is no longer developed. It acually worked really well.
I think Panasonic would be best to implement a similar tech in 4k/6k photo mode. Call it highres shot. Capture a second of frames, use digital image stabilization to align, then clean up noise and merge to 4x output. Would be really easy for them with GH5, GH5s and G9, with high end processor.

Horshack: "With a mean time between failures (MTBF) of 2.5 million hours, or over 285 years"

That's an impressive stat but relates to the failure of the entire drive. A more important stat would be the mean time between uncorrectable data errors, ie bit error rate.

@ chicken balls,
Yes I have been using as my main computer a Toshiba satellite 2450, with 2.4GHz, 1Gb ram, 120GB hard drive as main computer with windows xp since purchased March 3, 2003. Sadly it died, or rather the hard drive became unstable just this January. I am now looking at new software and shifting to a cjeap Dell 3646 ($100 computer) with Windows 10 until I figure out what I need.
I do have an older 60GB hard drive which I may test out in the old Toshiba to see if I can get it back. It had a FireWire port which is rare, but allowed me to connect my SLR/n and Panasonic 200 3ccd video camera.

On article Alien Skin Exposure X3 review (219 comments in total)

Thank you for the review. I think you saved me time trying this software. On the surface I don't see any added benefit over the free Phitoscape X, and at this price point might as well go with Capture one.
The competition is really strong now and the free options are really good.

41mm: As an SIGMA/FOVEON user i am not INPATIENT, but where is the RAW/DNG support of the X3F files fron X3 !?!

Come on guys, try harder - do not be ...

THINK DIFFERENTLY !

In my recent tests with x3f files I found they can be opened with the free software chasy draw ies. But the conversion is dull, soft and noisey. So not really worth it.
Affinity photo surprised me in ability to open the files, from Sd14, Sd1m and sdq. The edits are very fast and the output is good. There are some noise artifacts, but only at the pixel level. I mention my Sd14 as its the last fully supported Sigma camera.
Sigma pro is still the best output, but on my computer takes minutes vs seconds for Affinity.
If uou haven't tried Affinity, I would recommend it.

dbateman: This is interesting information for those upgrading within the Sony system.
However, looking outside an important element to acceptable high ISO is also your lenses. I have a Panasonic GM5 and a Nikon DF. I was surprised that the high ISO performance was equal when shooting and not 2 stops better for the DF as I would have expected. In a recent controlled test, it seems to come down to the lenses. Using my what seems to be softish 24-85mm VR on the Df, once there is noise the acceptable high ISO image sharpness drops. My PZ 14-42mm seems to be much sharper allowing for similar settings. Similarly for my Rokinon 85mm f1.4, is much softer than my Panasonic 42.5mm f1.2.
This worked out as an easy test, both cameras are 16Mpixels so got the exact same frame and used the exact same exposure. They matched, which was kind of a bummer. I will have to test my Nikon AIS lenses next. I still like the handling of the Df, but oddly my m43rds is my go to for interior higher ISO.

@chriswy,
I haven't done that test at high iso with my cameras. But I find the color, sharpness and noise to be fully usable on my copy of the GM5 up to 6400. I will push that to 12800, for sleeping kids. For my copy of the Df, I can accept 12800, but its not significantly better than my copy of the GM5. My VR 24-85 which I bought new at a ridiculous $600, vs my used PZ 14-42mm (ois) which I got used for $100, I think makes the difference. I do need IS, and I did the controlled test on tripod to see what was going on.
Now I am in software hunt to see if I can get more out of the Raws.

@slideshowbob,
I know!, that is part of why I made the purchase. But with my set up its the same. Thats why I made this comment about the lenses. I Don't have the soft Olympus 45mm that was used in that test or that sharp Nikon.
With my soft Nikons the Df is soft and noise makes it worst.

If they want to be #1, they have to get into the car market. Every car now has a back up camera and some have a front and right side camera too. The newer electric cars have even more sensors around the car. Then add in the millions of cars sold, and then you will be #1.

jonby: After, what, 35 years of AF development, we finally get this feature (AF bracketing). Can't understand why this hasn't been a standard feature for years. Well done to Fuji for being one of the first to get there. Kind of ironic that the first implementation is on a camera that perhaps barely needs it (sensor-based AF). Where this will be of most use is on phase-detect DSLRs. Always had a lukewarm/negative reception when I've argued for this in various forums because either 'it can't be done', or 'why is it needed?' Er, well if you care about getting your subject sharp it is.

I agree focus bracketing was a great feature on the Olympus E500. Too bad they dropped it for years, but back since EM1.

Yves P.: Only 4 years too late

I don't think there is a too late. But you definitely don't want to be first. Minolta/pentax were first with IBIS, and that way of doing it is dead. The Olympus/Sony way is effective and has taken over. Sony now uses the Olympus IBIS tech instead of the Minolta tech that they own because its better.
Also have to see if the 3 color Sigma like sensor designs that Canon and Sony have patented will come to market. On paper this new sensor tech looked better than Sigmas. But will not know until its out. Again late, but better.

msolea: Interesting camera, but I am more intrigued by the a7rIII.... Also, I guess Sony misled the public with an earlier announcement, I think it was with the a9, that stated every new camera release would be paired with a new lens announcement. But, I guess it is not the first time a tech. company deceived the public. Anyways, I still plan on investing in a Sony camera system soon.

Sony owns a large part of tamron and tamron is going to make some lens anoucements. So I still think they are on course.
But also looks like Sigma will anouce new E mount lenses. So I do think they are covered.

In reply to:

Edgar_in_Indy: I just about die of sticker shock every time a new "consumer" m43 telephoto lens is announced. It's like you either have to choose between dog food or filet mignon when shopping for m43 telephotos.

Tamron sells a very nice 70-200mm f2.8 DSLR lens for $769 new. It features internal zoom, and has close-focus abilities. When DPR reviewed it in 2008, they found that it delivered "Excellent optical quality" and was capable of "matching or even outperforming the much more expensive Canon 70-200mm F2.8 L IS USM".

Would anybody else be interested if Tamron made something similar in m43 mount? I know I'd be first in line. I think I could live with a touch less sharpness than Panasonic/Olympus's latest wonder-lens if it meant saving $1000 while getting a longer and/or faster lens.

Something like this from a 3rd party undercutting the high OEM prices may serve as a much-needed wake up call. Give me a good lens I can afford rather than a perfect lens that I will never be able to justify!

@Edgar,
Now I understand your comment. I thought you were comparing outside format. Sorry for my mistake.
Given your shutter speed I am assuming fastish motion. A mmf3 adapted Olympus 43rds version may work for you. I find the auto focusing slow on my Gm5, but used prices are cheap. If you have an Olympus body it may be better. I still have my E3 and its about twice as slow on the GM5.
An other option may actually be the 100-300mm this is a cheap lens and with the custom tripod foot you can buy from Germany it works well on a monopod.
Other than that you can try the metabones adapted sigma and canon mount lenses. One day I may get the sigma 50-100mm f1.8 in EF mount. Its very sharp, reported to focus ok adapted and with a speed booster its an f1.3 lens. Why I mention is I think sigma has it on sale now for $1000.

@dmanthree,
Ya I just went looked at all the options. Even consider Canon as could also us on m43rds with metabones adapters. But cost and size is just too huge.
I do find this lens out of cost reach for me as well. But I don't think its over priced like people are commenting. When I bought the Olympus 50-200 f2.8/3.5 it was $1399. I was lucky to get it for $700 as a photo shop went bankrupt and I caught the 50% off period.
This lens is tempting, but I may just go with the 45-200mm, at the tele-end only loose a stop.

Your comment seems odd to me.
The Panasonic 35-100mm f2.8 is close in cost to the equivalent tamron lens you are talking about.
Also the 45-200mm f4/5.6, if you want telephoto is 1/3 the cost of this more pro lens. The mk2 also is weather sealed.
I find no other manufacturer to have the full range of lenses as m43rds, and at equivalent field of view the m43rds are the cheapest.
I also shoot Nikon and sadly there is no 200-600mm zoom to match my panasonic 100-300mm f5.6 lens. The tamron and sigma 150-600mm come close but still at more than twice what I paid for a good Panasonic copy.

On article Buying Guide: Best cameras under $500 (154 comments in total)

Maybe this needs another update. Maybe due to the GX9 release, but the Panasonic Gx85 is running cheaper than the Gx850. Listed as $540 with the excellent 12-32mm lens.
It may almost take the cake for best under "$500", if you buy the GX85 with dual kit lenses for just $600!

On article Sigma announces full-frame 14-24mm F2.8 DG HSM Art lens (233 comments in total)

Interesting that they offer it without the petal hood.
I cut the hood off the 8-16mm and it offers alot of advantages without it.
1. You can use it for tilt shift on M43rds camera.
2. It works from 11-16mm on my DF in 135 format without vignetting.
Great to see the option here. The 8-16mm has a slide in cap that still works with the petal hood cut off.

I think these comments are too harsh. The images are good. The music is ok. Just the timing is really quick, reminding me of baraka, for modern day attention spans.
If you care about the images or want to know what your looking at then films like Babies and Baraka may mot be good. But for the general masses, they seem to like them.
