On article Does sensor size still make a difference? (1053 comments in total)
In reply to:

mr_landscape: Ads of Samsung, Canon and Sony. Sequentially.

They are trying to force people to forget about ol'gold stuff, like Panasonic CM-1 and Nokia 808.

Computational photography is still at offspring stage, so it is unlikely can be used for commercial purposes. N808 bends over Huawei P20 Pro in terms of resolution in daylight, like a glove. Huawei 4k video recording have 20 mbit bitrate. Oh my, the same quantity that 808 had for 1080p.This is pretty funny [6 yo ol tech rule the situation].
Huawei should put more tiny sensors in next model, maybe this helps out a bit.

My dream camera:
Body: Olympus PEN-F body with fully articulated screen.
Sensor: Sigma FF Foveon tech
Video abilities: Panasonic GH5

But it's a pity, that such camera will never-ever be released, because of marketing cr#p, no matter what technologies will be available at the moment. They need you to buy multiple devices *always*, don't you understand? That's utterly transparent. And i what to have one all-rounder.

I concur about Foveon Tech!

Literally same dream idea as you.

Julian Kirkness: I've been reading these comments with great interest - but as I read I started to wonder whether we are, in fact, at the beginning of an even bigger paradigm shift in photography - of computational / ai based imaging.

Much of the talk has been about the size of fast full frame lenses - but what if we no longer need to control depth of field with lens aperture or the exposure for that matter?

Before everyone ridicules this thought, there is actually nothing 'natural' about the shallow DOF effect caused by fast lenses - our eyes don't see that way. It won't be long before AI based imaging will be able to reproduce similar effects that we would be very hard pressed to distinguish from optically produced (and similarly artificial) effects.

Along the same lines, with increasing speed sensor readouts surely it's not long until a camera can control the exposure just with the 'shutter speed' - which would be entirely electronic.

...

There are some cameras coming out soon that will be capable of 'deep learning / machine learning'. So your idea is definitely a possibility.

Mark Chan: No; mirrorless long primes or zooms DO NOT weigh and are NOT similarly sized vis a vis full frame counterparts. They are definitely lighter and shorter.

Hmm, I'll have to disagree with that. The title: Why Nikon and Canon should build mirrorless as a second system – but probably won't

I do not see a problem nor do I think I misinterpreted.

Yes a FF mirrorless was Richard's proposal. The idea of a mirrorless isn't FF only though and so my point of contention in response to Richard's article was exactly that.

You will notice his claim that mirrorless lenses are not necessarily smaller came before his ' Opinion'.

And with camera; size comparison.

JackM,, JonB1975,

You are quoting Full Frame Mirrorless vs Full Frame lenses; The OP - I quote:

"It's not necessarily true that mirrorless promised to be smaller but, not least because it started with Four Thirds and APS-C sensors, that was one of the differentiators when MILCs first appeared."

Mirrorless camera go beyond SONY. And so have fun comparing the sizes. I care about how heavy a camera set I need to take with me.

OLY 12-40mm (effective range is 24 - 80mm) F2.8 382g;
Sony FE 24-70mm 2.8 GM - 886 g;
Canon EF 24-70mm 2.8L II USM - 805 g;
Canon EF 24-70mm f/4L IS USM Lens 600g;

Olympus 40-150mm (80 - 300mm effective) F2.8 - 880g
Sony FE 70-200mm F2.8 GM - 1480 g
Canon EF 70-200mm f/2.8L IS II - 1490 g
Canon EF 70-200mm f/4.0L IS 760g

Olympus 300m F4 - 1,270g
Sony AF 500/4,0 - 3.460 g
Canon EF 500mm f/4L IS II- 3190 g

In retrospect, I have to agree with the OP; Going FF mirrorless is less about the weight loss than about the upgrade in key tech such as the EVF

Yannis1976: There is a Greek rhyme which I will try to translate in English: "From all the blinds the man with the one eye distinguishes himself". In other words underwater IQ in all of them is not that good due to their small sensors. Olympus is simply the best due to its faster lens but only marginally, since it shares the same tiny sensor. In good light they are all fine.

Was gonna reply with the above. Someone told me about this especially when discussing doing business in Africa - way back.

In reply to:

ProfHankD: You know, Olympus has led this market for a while, but I still think the TG-5 misses a bit. People don't seem to understand that in tough shooting situations, availability of a very wide view angle and flexibility about how you view the display are more important than normal. Instead, we see companies building two lines: hardened point-and-shoots and ultrawide/fisheye action cameras.

In 2015, the Olympus Stylus Tough TG-860 came out with a 21-105mm equivalent lens and a tilting LCD that allows angling the screen so you can see the live view without having your face directly behind the camera (it even allows selfies) -- both of those features are qualitatively more useful than what these other cameras offer. I just wish Olympus had continued TG-860-like models, especially improving image quality....

The TG-Tracker is definitely not a replacement to the TG-870.

I would think they'd put one of those out just to continue playing with the other companies.

The TG-5 wins hands down here with their F2 aperture. I feel they are hitting the sweet spot for combo users that take both photo and video.

Alas no 1 incher in sight.

rmexpress22: I kind of wanted this when I first read about it but not anymore seeing the comments regarding zink. I didn't even know what that was until now. But if the quality is bad or it fades, I'd rather get a tiny printer and power it with my vagabond mini that I barely use.

I think it'd just be fun to do. I don't even really care about printing but I think a lot of the people I shoot would get a kick out of it.

I bought some Zink photo papers to work with the polaroid camera / printer. Probably one of the worst purchases ever.

I've actually had experience with all the portable types; dye-sublimation from Pringo (search them up); Instax from Fuji (camera type and the newest SP-3). Both of these just blow Zink tech out of the water. Dye-sublimation is still the best, but the Instax gives you that unique touch.

phazelag: I plan to buy one so I can print all the photos I transferred instantly from my Millennial loving canon M50. This should upset a large group of canon haters, youth haters, and smartphone haters, but I will have a lot fun with my kids and friends.

Check the Fuji SP-3. Zinc tech (not canon tech) is crappy; it’s the Photo medium at fault here and honestly instax much better.

cosinaphile: zink prints are 2x3 or 6 sqin and cost a buck canon selphy 4x6 prints are equal in size to 4 zink prints [24 sqin] cost about 28 cents [us] each

zink are enormously more costly than selphy considering price to size

Get the Fuji SP-3; equally costly, just as portable, zippy in use, and just as portable (give or take an inch or so).

Or Pringo 2 by 3 inch printers for the dye sublimation option.

Larger by a bit but every bit a dye sublimation Print!

In reply to:

Kharan: I give Canon's Imaging division loads of crap for the things we all know about. But their Printing Solutions products are actually pretty good. I own three Canon printers (a PRO-100, a Selphy CP-1000, and a cheap document printer), and I must say that the things are sturdy and reliable, as well as very easy to use.
Canon is also the only company that truly supports home photo printing in my country, and I'm glad for that (the market is tiny, and it must take some effort to keep the products available).
I don't doubt that this new device will do well, and probably even beat the competition in terms of reliability and ease of use.

Rubbish Zink Tech quickly nullifies it’s brand I would suspect. It’s not the printing process that’s the issue it’s the print medium.

In reply to:

Techo: I haven't seen a decent Zink print. Kudos if they bettered the IQ. Otherwise, I hate to say this but, I'd prefer Fuji Instax.

Since the tech isn’t canons in the first place I doubt if any improvement can occur. It’s more like a ‘me too’ product.

Link | Posted on Apr 22, 2018 at 04:17 UTC

It’s doesn’t seem to me this will break the photo quality of Zink prints. Unless the production process of the paper gets a significant upgrade, it’ll be inferior even to Instax.

For a good portable device with dye sublimation you should look for Pringo products From Taiwan. Portable, app base. That’s the cheapest on the go 2 by 3 inch option out there - including silver or gold glazed or even sticker based options.

However for me the new SP3 gives the most unique prints - instaxstyle prints from any digital photo.

I’ve had all 3 types; the Zink prints fade very quickly and poor storage will tint the paper.

entoman: Amazingly compact for a 100-400mm equivalent sports lens. Great move by Panasonic. Is this fully compatible with all functions of Olympus EM1 Mkii?

Entoman - I appreciate what you say there - sometimes that money shot just doesn't give you time.

If you checked, you'll probably understand that OLY's ethos is to have as little postprocessing as required - at least that's what I see.

Entoman, think about it; you get a much lighter overall package and albeit more expensive probably longer range. You can haul more gear at lower overall weight and do less cropping. ISO 1600 should be achievable. IF you are able to get the closer shot, more comfortably, wouldn't it be nice.

I would recommend you do the weights math; the $$ maths would be an issue though.

Having said that I must be a weak 40 year old; I have chronic tennis elbow issues just by using my OLY E-M1 mk11. duh.

This is another perspective by other people that apparently know the person more than most of us commenting here.

I feel its important to be empathetic then judgemental with regards to unfortunate incidents such as this one.

Fujica: This 'accident' could have been avoided by using a SO2 detector. An essential tool when you go and visit to such dangerous places like a vulcano.

As described in the article, it was a result of sudden changing environmental conditions leading to toxic STEAM; so its the rain that led to the unfortunate circumstances. Taking an SO2 detector won't have helped much as it would have high readings throughout anyway
