Slouch Hooligan: The circular nature of the discussion here could be summarized:
10 larger sensors produce better images
20 phone cameras are pretty good
30 99% of the customer base doesn't care
40 GOTO 10

"99% of the customer base doesn't care"

even if this statement is correct. 1% of all people in the world (6 billion?) is a big big number
How than can phone kill entry level ILC ?

Doesn't make sense

image stacking in phone is the truly threatening feature
Google pixel already show by stacking multiple pics small sensor already overcome lack of dynamic range

but can image stacking overcome bad low light IQ ?
I don't believe so. How can the phone stack multiple image in low light if even a single exposure is difficult to handheld

But I may be wrong. Maybe it can take a bunch of underexposed pics, than stack it and get the correct exposure with much reduced noise like big sensor camera?
If phone can truly do this, than big sensor camera would really be in trouble

for now the far superior low light IQ of big sensor wouldl ensure it won't be replaced by phone

Badbatz: Yeah, the future belongs to tiny sensors and bad wide-angle lenses. And it is filtered by Instagram. Right...

Sorry, Allison, but cellular phones capabilities are less than that of the dinky 200 dollar digicam in terms of photography, unless you count "made with iPhone" fakery where an iPhone is just a tiny part of a fifteen thousand dollar rig...

"I disagree! I cannot see a difference between my Galaxy S6 and X-E2 in daylight conditions. ILCs are overpriced."

What about in low light? u don't take any pictures in low light?
You answer you own question

Peter62: I think that ILCs and DSLRs offer too little for what we are paying. The benefit of having an ILC is too small compared to a smartphone. How can it be, that a thumbnail-small smartphone lens produces the same image quality (in daylight) like an ILC with a "monster" lens?

Truth is: ILCs and DSLRs are heavily overpriced.

you said it already , only in daylight
in low light u told me a APS-C sensor with kit lens produce the same image as a smartphone?
One always take pics in good lighting?
Truth is most people just don't care IQ . entry level ILC are still far superior camera compare to phone but if one don't care IQ than it doesn't matter

for those in the know. $500-600 to spend on a real camera and get good IQ is not entry level ILC with slow kit lens (those are only worth it if if one plan to change lens)

What will truly offer a giant leap in IQ compare with smartphone is 1 inch sensor compact camera with very fast lens like LX9 with F1.4.

That would especially in low light create pictures that even a blind eye can tell is different from smartphone

Jefftan: Even now smartphone has not killed compact camera. Tough and mega zoom compact camera still survive

So why would it killed $500-600 entry level ILC. Another sky falling alarm. Sales may reduce but totally kill them as to not exist any more?
Highly unlikely

Even if only a small percentage of people in the world want a big sensor real camera, entry level ILC can survive, at worst is reduced sales and marginal players exit the market

I may add even if someone just want to pretend to be a real photographer for whatever reason (like to impress the girls )

They need a big real camera like a D3400 or A6000. I see lots of those guys in HK (must be the same everywhere)

They actually know nothing and only use "auto" mode but they buy big camera and not use phone (which is what others all use)

rrccad: Also .. as far as page 3. Sony sensor crop factors have been slowly inching their way to 1.55 anyways.

I think right now they are at 1.54 crop.

so to suggest a difference in crop without really looking at the actual sensor size, is a little disingenuous.

(canon is 1.61 and nikon is 1.54 in this case). essentially a 9% difference in actual area.

(canon is 1.61 and nikon is 1.54 in this case)

if true than 18mm kit lens is 29mm in canon vs 27.7mm in nikon
a difference of 1.3mm not as significant but still make a difference in landscape because 27.7mm is already borderline for landscape

for ultrawide in 10mm is
15,4mm vs 16.1mm a difference of 0.7mm maybe less significant

are u sure? same for Sony A6000 series camera
all info I read said 1.5x crop for both sony and nikon
u are saying no and is really 1.54x?
hard to believe, how do u arrive at thar 1.54x number?

eddie_cam: Are front focus and back focus issues still a thing with DSLRs? AFAIK mirrorless cams don't have that.

dual pixel solve the problem?

Link | Posted on Aug 9, 2017 at 16:10 UTC

lens choice most important consideration, for me I like ultrawide and so will choose Canon because EF-S 10-18mm seem to be better optically than DX 10-20mm

In reply to:

Jefftan: for landscape shooting, in my experience
27mm vs 29mm make a huge difference
every mm count

for most who will only use kit lens, a serious concern if camera is for landscape

why 28mm not 27mm, don't understand, isn't Nikon like Sony 1.5x crop?

Please tell me if anyone know
Which is better in real world use
Canon dual pixel vs Sony A6500 on sensor pdaf
thanks

Anyone know if there is lens profile in any RAW program to remove heavy vinetting at F2?

In reply to:

Jefftan: My experience using it on GM5
1 heavy vinetting at F2
2 even bigger problem
in A mode using multi metering, image is ofter seriously underexposed (more than 1 stop) but some are metering OK (camera don't know aperture used and no way to tell camera)
Should I switch to center weighted metering? Anyone know? Thanks

GM5 using A mode multi metering in cloudy sky, many shot underexpose by huge amount (more than 1 stop)

In reply to:

HaroldC3: Honestly, I feel a little sick that I bought an overpriced M6 with the SL2 now coming out at a very attractive price. Especially if the SL2 has a silent shutter option as evident with the drive modes silent single and silent continuous.

I guess Canon was right to think they are competing with themselves because this camera definitely competes with the M5/M6.

so no real physical shutter used in live view? only electronic shutter? if so have drawback like reduce dynamic range/more noise

no mirror slap in live view shooting? correct?
