On article Canon EF-M 28mm F3.5 Macro real-world samples (18 comments in total)

(repost from an M forum thread): I was a bit confused trying to compare these numbers on my favorite lens review site, photozone but then I realized that

DPReview is giving LP/PH while photozone is giving you LW/PH.

There's a (simple) formula on the imatest web site to convert between the two

LP/PH=(LW/PH)/2

So if the excellent EOS-M 22mm was measured by photozone as LW/PH 1700 that would be the same as a 850 LP/PH putting in the same league as the 28mm for MTF50.

But according to the lensrental.com, MTF50 may not be best measurement for determining the quality of a lens for macro work:

"Landscape and macro photographers trying to get the most detail in their large prints might consider MTF10 to be more important, or at least nearly as important, as the MTF50."

Ref:
http://www.imatest.com/docs/sharpness/

This is a nice explanation of why MTF50 is not always a good number to measure real sharpness:

On article Apple planning to open imaging research lab in France (43 comments in total)

I wonder what the ratio $$ spent on research for mobile phone photographer to dedicated cameras is.

I've also wondered why Apple does not come out with an IOS based large sensor camera or DSLR.

There would not be much overlap with the existing iphone market but there would be a lot of overlap in the expertise required to bring out a consumer friendly "real camera".

In reply to:

keeponkeepingon: "It's an entry point to the wide and wonderful world of Canon glass"

dpreview should give a price and score for a standard kit.

For example, Looking at the specs of the A6000 it looks like a bargain but once you try to put together a system with several lenses the price skyrockets.

Canon's strength is not in this one body but in that this cheap body buys you into very affordably priced APS-C system with great IQ.

You can cover 10-250 with zooms for under $450 and throw in a few primes for $150 or less each. And each of these lens tests and reviews spectacularly for the price:

10-18 ($230-$300)
24mm pancake ($150)
50mm ($125) (or 40mm pancake ($150))
55-250 ($140)

Total: $715

A similar system for my sony A6000
10-18 ($750)
20mm pancake ($350)
50mm ($250)
55-210 ($350)

$1700

Over twice as much. For the price you should get better quality but while a couple add OSS, not a single one of the sony lens tests or reviews better than their canon counterparts.

For a grade/rating I'd give the Canon kit an A and the Sony kit a B. While the UWA, and 50mm are decent the quality of the sony kit is dragged down by the awful 16-50 kit lens and meh 20mm.

I also don't like my sony 55-210 as much as I like my canon 55-250. (just personal experience no "testing" and their may be some sample variation involved).

FRANCISQUAN: DPR by their own admission find the two and a half year old Nikon D3300 pretty well wins in all situations here.
But then the EOS 1300D has Wi-Fi which according to this DPR review makes it the best ????

Wow?

Had to chuckle at the Eye-Fi recommendations as the article above this claims Eye-Fi is dumping 14 products and cards purchased as a year ago will no longer be functional.....

FocusBogus: Cheap camera=junkyard and drunk photos. Mid-price camera= better, artistic photos ja landscapes. Expensive camera= beautiful nature shots, sunsets, art galleries, lots of bokeh and dof.

Thank you Dpreview, now I am wiser.

Nothing's 7 years old. Canon has refined their 18mp sensor over 7 generations. It's now at it's peak, get it before it's gone.

In reply to:

Interestingness: I have a tween daughter that has a birthday next month and she wants a camera. Dad shoots with a Canon, and her friends parents have Canon's. She's young, it will probably be dropped and broken before it ever wears out and if it doesn't get stolen or left behind somewhere, there is a good chance it will suffer water damage from the pool.

You guys that are OBVIOUSLY pro's based on your well thought out comments (and those amazing galleries and personal webpages you hold) are totally correct - instead of buying her something like this I should drop $10k+ on the latest and greatest full framer and a bagful of lenses, right?

Dumbasses. Every time I read the comments here my IQ goes just that much lower.

iphone/ipod is a better camera for $500 or less for a tween.

If it has to be interchangeable lens and you want the ancient 18mp sensor get her the $450 EOS-M10 with the 15-45. Or go with the body-only ($250ish) and and a $100ish open box 22mm F2. The former will be a more "selfie friendly" FOV (plus the flip screen = selfie heaven) and the later will give her much better IQ than the T6 with the kit lens, you'll save $50 or $150

keeponkeepingon: My eyes! The goggles do nothing!

Gosh that's bad. If y'all would like to make your page look less 1999 how about adapting your width or designing your page for wide monitors. So much wasted space and nothing says "old" or "dated" like wasting 50% of my screen space.

"(I'll bet your browser has zoom functionality".

Really? Big letters is still wasted space.

"works great "

Zoomed so the page takes up the width of my monitor I can fit one post from this thread on the screen. Unusable.

Simon why not just have amazon or sony pay for the redesign?

In reply to:

keeponkeepingon: IR claims the A6300 locks up for 22 seconds after a burst. Yet no mention of this by dpreview?

Or did I miss it in the review?

"buffer clearing is slow and the camera doesn't allow you to do anything while the camera is clearing the buffer. Clearing an 11.1fps burst of 21 RAW+JPEG files takes 22 seconds, which is quite slow. "

http://www.imaging-resource.com/PRODS/sony-a6300/sony-a6300A.HTM#overview_start

Sony Alpha SHooter. I own an A6000 and can verify that after a burst I can not preview images or make adjustments to the camera settings for 20ish seconds
after a burst.

That may not affect "spray and praying" 4000 images in an hour but I find it very irritating and it gives the camera an overall "point and shoot" feel.

dpreview gives 1/2 a sentence to this issue in the A6000 review but fails to mention it in the A6300 review.

Dan
According to imaging resource the A6300 has the same issue locking you out of image preview and many functions after a burst.

Dpreview swept this issue under the rug on the A6000 review by not mentioning it in the conclusion, and failed to mention it at all the A6300 review.

http://www.imaging-resource.com/PRODS/sony-a6300/sony-a6300A6.HTM

"Buffer clearing after max-length bursts took some time even with a fast UHS-I SDHC card, though, ranging between 15 seconds after a max-length burst of RAW files, to a rather lengthy 36 seconds after a max-length burst of Large / Extra Fine JPEGs, and the camera won't let you adjust settings or view just-shot photos while the buffer is clearing"

Retro1976: Wow, is this Sony Central ? Man I would easily pick the Olympus EM10 over the Sony A6000. Olympus has a better EVF, incredible in body IS, touch screen, fast auto focus (with touch AF), wayyyyy better JPEGs, and an incredible lens selection. Dpreview, do explain yourself, your bias is really showing :)

" there is a reason the A6000 has been way up the mirrorless charts on Amazon"

Yeah it's not like amazon purchased the leading camera review web site to pimp their favorite products. Oh wait.....

In reply to:

PatsyK: is there a program for windows which with one scan of say three pictures, manages to save them to three separate files? Or crop them into three different files in the scan program?

The free software that comes with my canon scanner can do this. You an even give it a photo album page with a bunch of pictures all askew and it will identify and straighten the picts.

carlg10013: It would be a shame if someone considering the FZ1000 is dissuaded by this review. I'm a veteran photojournalist who uses it extensively for stills and video for about 70% of shooting that formerly would have required a DSLR. And the fully articulated LCD, not available on the RX10 III, is a huge plus with video. The camera is a gem!

forpetessake "So, do you have a separate monitor or a TV in a portrait orientation "

I'm not sure who you are responding too but this is my preferred monitor configuration. I call it my "T" setup because the monitors make the shape of a sideways T.

Portrait orientation is great for web pages (less scrolling) while landscape is better for some apps such as LR. Best fo all worlds......

" Or are you one of those who like to look at small pictures on a large screen monitor mostly filled with black or white color?"

This gave me a chuckle because it's exactly how this dpreview comment section looks on the landscape monitor. Small column of text on a field mostly filled with black.

Gosh the distortion is irritating in the movies. Is it barrel distortion like you'll get on a wide lens (and in theory correctable) or distance perspective distortion (harder to correct).

Regarding changing the FOV. Is this done optically or by cropping the image (lower quality?). Thanks!

On article Lens shootout: Sony RX10 III destroys the competition (488 comments in total)
In reply to:

keeponkeepingon: According to the EXIF data for the space needle pictures, the Sony and Panasonic pictures were not taken on the same day, they were taken a week apart. (2016:05:11 15:12:36 versus 2016:05:18 16:10:41.041)

Given the level of pixel peeping going on here is it possible we are looking at differences in atmospherics/air pollution versus differences in cameras?

Pixel peeping is fine if you are comparing apples and apples. In this case the pictures were taken at different times of day (different levels of light) on entirely different weeks (7 days apart, possible different atmospheric conditions).

This should be disclosed before presenting the picts for peeping and before declaring "destroys the competion" based on said peeping.

Sigh. WD should just buy out Seagate and be done with it.

In reply to:

nir-vana: It might be interesting to see how it compares to the FE 70-300 on A7Rii.
Equivalent FL comparison and also 300-cropped-to-600 vs the RX10iii.
With such good IQ as it seems in the parrot photo it might be better to buy the RX10iii as a 2nd camera for telephoto, instead of the 70-300.

It'd be even better to see it on an A6000. Almost exactly the same price for the combo, and with the crop factor your at 450mm FF equivalent. You can crop down to 600 but it would be really really interesting to see what both do at the 450mm FF equivalent.......

The review is trash. Look at the comments. Some of the test pictures were taken on different weeks at different times of days (later in the afternoon so less light for the FZ1000). Very disappointed in dpreview on this one......

Wow. I really like this. You take your time with it, play with it, give a fair analysis and then throw in an interview at the end. Well done Damien! Is there any chance you could start doing Camera reviews too?
