Note series cannot be compared to regular phone. Note is based on stylus. And there is no other phone that has same level of stylus usability.

Hope my Note4 will last long :)

It probably will be SONY A7 modded to retro styling. They already have E lenses

Anyway K mount camera and K mount lenses like they used to do might be more interesting for me .)

Put a K mount on it.. that will enable both K lenses and M42 lenses with cheap adaptor..

In reply to:

Class A: "Modern zooms still aren’t quite as good as a prime lens..."
Not true.

Modern zooms, at their optimal focal length, often surpass prime lenses due to their more elaborate construction. Zooms require more correction for their extreme ends and all the lens elements used to this end, create an excellent performance for non-extreme cases. The advantage of primes is mainly smaller size and less weight.

I'm not making this up, this is information by Dr. Hubert Nasse from Zeiss.

Also, the use of helicoids does not imply that all lens elements move in tandem. Zooms with independently moving groups are very common; this is not a special trait of the discussed Minolta lens.

DPReview really should apply some minimum quality control before publishing such articles.

Image output is not only about sharpness and correction. There also are contrast, colour transfer, rendrition, bokeh and others. Fixed focal lenses with low element count have less problems with light wavelength separation than multiple-element lenses.

Zooms are zooms, fixed lenses hold their own. And it definitely is not only about size or price.

Pop-up flash is useful when you are in pitch darkness only with your camera and some light walkaround lens. Some people are not willing to keep 400-600g flash still in bag.
Another thing is wireless flash command function.

What have we learned? There are many paranoic commenters on the side (regardless of the brand they use and/or like)

All those Canon, Nikon, Sony, Fuji reviews.. That means they turned their back to Pentax!

Forget FF with unimpressive overpriced rebadged tamron lenses, build proper APS-C cameras like you used to do 6-7 years back, overhaul ageing old DA/DA* lenses and enjoy growing market share. Otherwise please sell the camera division to Sigma.. you failed.

When 1.6x crop Canon raw output at high ISO not only is way worse than Pentax K70, but even worse than Olympux 2x crop...

Congrats Canon..

In reply to:

Akpinxit: What about simply placing the film negative on smartphone screen illuminating white (such as any LCD flashlight app) and taking photo with DSLR (with tripod for optimal quality) ?

You'll take picture of the display matrix.

White balance is no problem, because only kids use JPG and any proper DSLR user shoots RAW.

In reply to:

Bambi24: Only thing I don't like about rebels is the small viewfinder.

I shoot rebels all the time, I'm not a beginner, I just don't spend a ton of money on cameras and prefer a camera I can use instead of cherish.

I can deal with having no exp. comp in manual+Auto ISO, or not being able to set min. shutter speed for Auto ISO, not having micro AF adjustment, I don't care about RAW performance at all (jpeg ftw).

Just that viewfinder...I would like it to be bigger and better that's all. (I know about the 80D, it's just a lot bigger and more expensive)

Maybe it's not possible to have a larger pentaprism without making the camera 80D size, but I believe it should be. I have shot full frame film camras too, and some of those models are smaller than 80D and have a beautiful large bright viewfinder, so it has to be possible imo.

Mirrorless have larger viewfinders, and this is becoming the achilles heel of rebels, because the first thing people do in a store.....is look through the viewfinder.

Get pentax.. you'll get proper pentaprism even in low cost K50

Compare hi ISO image quality with Pentax K70.

Canon missed the train.

Even some m4/3 cameras do better.

On article Sony a9: Why being better might not be enough (767 comments in total)
In reply to:

surlezi: No black out.
Totally silent.
Best in class AF (according to Northrup who compares it to D500).
Joystick + Touchscreen.
EVF.
Battery life OK.
Dual SD card, among which one UHSII.
Menu Ok with "my menu" and other improvements.
Need bigger grip: there an extension grip and a battery grip.
Glass partly here, more coming.
4K.
Presumably better Dynamic Range than Canon and Nikon counterparts.

There might be some downsides, but most issues are adressed, and lots of best in the class features.

This camera and its glass is perfect for wedding shooters.
The camera is great for sports shooters and glass is coming.
The Camera Store guys are convinced it will sell like hot cakes for wedding shooters. They also believe it's a milestone camera for mirrorless, as well as DSLR: the EVF is now better than OVF.
Slapping mirrors will forever have blackouts and vibrations issues limiting their fps.

Thank you for everything DSLR, and Rest In Peace.
Now let's enjoy a superior technology.

It depends, you can use canon lenses on that Sony to some extent..

I like my Sig 100-300/4

100-400/5-6.3 is not worth existence. 60-300/4-5.6 FF lens would be more interesting both for APS-C and FF users.
