On article Shooting live music with the Panasonic Lumix GX9 (91 comments in total)

From how the photographer describes the GX9’s auto focus, my old Nikon V1 camera outperforms this GX9 with its superior PDAF even when using a smaller aperture lens.
I find it amazing how tolerant DPR reviewers are of the mediocre AF in the m43 cameras that still rely on CDAF like the old P&S cameras of yesteryear while others are incorporating on sensor PDAF in their mirrorless cameras with far better results. I can’t help but wonder if a DSLR only had CDAF would DPR rate it at even 50%? It’s way past time for DPR to start downgrading their rating of m43 cameras until they get PDAF in them. Come on DPR, this is 2018, not 1998!

On article Nikon teases mirrorless with video and microsite (1290 comments in total)
In reply to:

The Fat Fish: I wish Canon would give us a similar hint as to their future mirrorless camera. Will it be a competitor to the A7III/A7RIII specs and price or will they release another outdated, underspec'd and overpriced camera?

Canon has more class than to look desperate for attention.

Dear Nikon,
Please don’t do any more of these pathetic teasers that are reminiscent of your, (now dead) “Key Mission” teasers. Just bring your mirrorless camera (late) to the game, or go home already.

On article Sony Cyber-shot DSC RX100 VI review (492 comments in total)

I love the concept of these 1” sensor compacts. It’s almost like having a mini DSLR in your pocket, but that is the rub. Such a small camera will likely find itself in a lint filled and perhaps even dirty pocket instead of a clean dedicated camera bag resulting in a dirty sensor. And then what? You can’t clean the sensor yourself and how much expense and downtime would be involved in sending the camera in for repair. These fixed lens compacts should all have extensive environmental sealing and be clearly stated as such, especially so at these high prices. Until they get the sealing I will have to pass on these otherwise excellent pocketable cameras. Are you listening Sony?

Excellent composition, but I don’t care for the yellow cast in the foliage. I much prefer shades of beautiful green!

On article Sony announces Cyber-shot RX100 VI with 24-200mm zoom (758 comments in total)

I really like what Sony has done for the 1” sensor format with their camera designs and the sensors themselves. This 6th and latest iteration in the RX100 series is a marvel of compactness and performance and will no doubt rival the image quality of the current m43 cameras at base ISO while leaving them in the dust in terms of autofocus tracking of moving subjects. Good job Sony!

Verto: Wow... ummm. Hmmmm... 2.8-4.5 on a 1 inch sensor? This is definitely a Step backwards. I had the current version and I got rid of it because the lens just wasn’t good enough. I was hoping the new model would have a redesign of the current lens. At 200mm and 4.5 diffraction is already going to affect image quality, not to mention the compact lens design. I’m skipping this version. 1 inch sensors need fast glass for good performance.

I have many examples in my DPR gallery of sharp images shot at 100mm (270mm equivalence) and f/5.6 on a 1” sensor Nikon V2. I even have a few handheld shots at 300mm (810mm equivalence) and f/6.3 with decent sharpness. So it is very possible this new Sony camera could provide excellent sharpness. Unlike some, I will wait for the written review to find out.

Mariano Pacifico: Whopping 24-200 !!! That is 8x zoom range. Bet the resolution and sharpness is going to be soft. The ideal zoom range is between 2x to 3x to retain sharpness but with computational photography maybe Sony can eke out resolving power, sharpness, contrast and flaws of physics.

I am old-school. I am not buying into this. I have deep respect of laws of physics.

The IQ will come down to the quality of lens and not physics. I shoot a 1” sensor Nikon V2 with a 10-100mm (27-270mm equivalence), and get nice sharp images even at 100mm. (Check my gallery if you don’t believe me). It remains to be seen how sharp this Sony lens is, but if the lens is as good as my Nikkor 10-100mm I would be very tempted to acquire this camera and sell off my Nikon 1 gear.

Shades of Pentax! Let’s hope this does not mean Olympus is running out of ways to be competitive as well.

On article Does sensor size still make a difference? (1061 comments in total)
In reply to:

Elonlukatski: Large sensors will produce better image quality. But when is good enough, good enough. I can not tell a difference between a FF camera and a 1" sensor camera when the images are posted online. What counts most is the quality of the shot in regards to lighting and exposure and composure etc. I think computational technologies are pretty new and in time will improve and do some amazing things. Maybe good enough kinds of things.

That may be the case at base ISO, but at higher ISOs the larger the sensor the better. I have to say though that the latest 1” sensor tech with BSI and on-sensor PDAF is highly competitive with m43 at this point in time and in some ways superior.

On article Does sensor size still make a difference? (1061 comments in total)

Having used virtually every camera sensor from FF in size down to IPhone, my conclusion is that the APS-C sensor is the sweet spot for the amateur still photographers wanting an ILC with excellent image quality in a smaller lighter package than a FF kit. The APS-C mirrorless camera body can be as small as a 1” ILC and primes or small aperture zooms (such as the Fujifilm 16-50mm F/3.5-5.6 XC OIS II), can be small and lightweight yet very capable. Fujifilm has shown the way with a high quality small, lightweight dedicated APS-C mirrorless system that is becoming increasingly popular amongst more advanced amateur still photographers.
M43 once seemed to hold much promise as the format of choice for amateur photograhers, but unfortunately lagging m43 sensor tech with no on-sensor PDAF or BSI that even cell phones now have has hurt m43 in this ever increasing tight market. Even Thom Hogan who was once a big m43 fan in the beginning has soured on the m43 format and no longer recommends it.

Nikon already tried a new lens mount for their stand alone mirrorless camera system and even provided an adapter (FT-1), that allowed mechanical aperture control with their AF-S lenses. It was named Nikon One and was a marketing failure despite having on sensor PDAF which can still outperform any m43 camera and most mirrorless cameras even today.
As someone who is invested in Nikon DX DSLRs and Nikon One mirrorless I have a good perspective as to the challenges Nikon will face in designing and marketing a new mirrorless camera system while trying to maintain compatibility with the current F mount lenses. Focusing with AF-S lenses on Nikon mirrorless will be unacceptably slow for many ,if not most users and may be restricted to the the center focus point only, and based on my knowledge of Nikon One, compatibility with third party lenses may be spotty or nonexistent. In short mirrorless does not look promising for Nikon’s future survival, unfortunately.

On article Olympus PEN E-PL9 headed to the US and Canada (184 comments in total)

I love the looks of this Olympus PEN E-PL9, however it is a poor value compared to the Fujifilm X-A5. For the same price of the Olympus PEN E-PL9 body only, one could purchase a Fujifilm X-A5 with a kit lens included. Plus the X-A5 has a much larger sensor and PDAF, which the Olympus PEN E-PL9 lacks. M43 cameras look a bit stale with their dated sensors and lack of PDAF which even the higher end cell phones cameras now feature.

The question is whether or not the consumer will trust Samsung products not to catch fire again. As the saying goes, "Once burned, twice shy!"

On article Upwardly mobile: Sony a6300 Review (2161 comments in total)

Only a small percentage of buyers of the 6300 will ever use prime lenses with it, so why are only prime lenses used in the reviews of the Sony APS-C cameras?
Answer: The Sony APS-C zoom lenses are junk glass that get terrible reviews.
If Sony ever produces a good quality native APS-C zoom lens for this camera, I would seriously consider buying one, (despite it's poorly designed grip and ergonomics). I keep waiting and hoping Sony wakes up some day and gets the news that optical quality is important to serious amateur photographers and the vast majority of sub FF sensor ILC owners (me included), rarely use or even own prime lenses. Poor lens selection for APS-C is one of the major reasons I left the Sony A mount, and six years later nothing has changed, unfortunately.

No doubt Sony cherry picked this copy among several lenses available to them, but the big question is how good will the quality control and copy to copy variations be in the production lenses that people buy, and how reliable will they be over many years of professional use. Maybe these new and very expensive line of lenses will improve Sony's reputation in this regard, or a least Sony is hoping they will.

On article What a view: Aukey Super Wide Angle lens quick review (61 comments in total)

This reviewer is much too kind to this lens, to the point that he has no credibility as even a casual photographer. All one has to do is look at the lousy images to realize this lens is a worthless piece of junk that will end up in at the bottom of a drawer or more likely in the trash bin. Save your money folks!

R.I.P. Samsung camera division. At least you gave it a good effort in an ever shrinking camera market. Samsung deserves kudos for that, at least. Despite the demise of the NX system, if I could get an NX1 with a 16-50mm f/2-2.8 "S" OIS lens, for under $500, I would still buy one. Still looking for that fire sale!

In reply to:

havoc315: So a big heavy ultra wide angle lens... That really isn't too ultrawide. Equivalent of 21mm.... I don't see much of a point to this lens.

I agree. I can't imagine changing lenses just to get to an extra 2mm of focal length (I own the Tokina 16-50mm f2.8.) No doubt one would have to stop down to f4.5 or more for decent edge sharpness anyways. The focal length range is too long at the wide to be a true UWA, which makes for a really useless lens design, IMO.
