What's the purpose/market of the 400mm f4 IS DO II?

MJ said:
Dear CR members, I don't quite understand the reason of the existence for this lens.

Sure it's nicely designed, weather sealed and doesn't change size, a bit shorter and lighter than a conventional designed lens, but for a walk around super tele lens it's still pretty bulky and heavy and *only* f4.

Point two is the currently still exorbitant price it's still (even with CPW specials going on).

There are other alternatives - like the 100-400 II which may not be as sharp and snappy but a hell of a lot more versatile, smaller and lighter at only one stop less for a THIRD of the price. If I were to drop more than 6K on a lens I'd go all the way and get 600/800mm lenses or a 200-400mm or at least a 400 2.8 II.


Am I totally missing something here?
I'm curious to hear what you think!

"What's the purpose/market of the 400mm f4 IS DO II?" Very simple! ME!!!!!

I have used a few Canon 400 F5.6 L lenses and they are very good, I have the Canon 100-400 Mk2 and it is very nice. The versatility of the 100-400 Mk2 for me is the close focus, as to the 100-399mm zoom - I could care less. Don't get me wrong it is a lovely lens and I am very pleased with my copy.

The 400 F2.8 is just superb but very heavy and simply too much for many users.

So we have the 400 DO. Have you tried one? If not do so - you might well be converted! The Mk1 version appears to have been very variable - I tried out 3 of them. One was pretty mediocre, however the other two out resolved my (then) Canon 600 F4 L IS at the same range - yes read that again. There was a little loss of contrast and colour vibrancy - but it was minor and easily corrected. The Mk2 400 DO virtually eliminates this and seems to have cured the copy variation as well.

If I could sell my 300 F2.8 L IS and 100-400 Mk2 and get close to the cost of a 400 DO mk2 I would do it in a heartbeat!

Good iPhone cameras lead to better 'proper' cameras

Don Haines said:
good for a laugh.....

Photography is the capture of light.... a 77mm lens captures 165 times as much light as a 6mm lens does.... no "magic technology" is going to make up for that!

Just you wait till Apple engineers perfect the groundbreaking technology of using Apple's famous reality distortion field to guide zillions of extra photons through that tiny lens... Who has the last laugh then?

Canon EVF-DC2 Likely Coming Soon

hmmm ... EOS M10 has no contacts to plug in an external EVF, correct?
And M5 comes with built-in EVF.
EVF-DC2 does hint to one more new EOS body [see Neuro's remark re. M10 -> M20 ?].
I don't think Canon would bring a new EVF for [now old] EOS M3 or G1X II.
Or maybe it is just for yet another needless Powershot G ...
How about a G1x3 with a 24MP APSC sensor, surely that wouldn't be needless!

to me it would be. I am not buying cameras without interchangeable lenses. When lens built in is sufficient, I us my smartphone. :)

I don't think Canon will put APS-C sensors in G powershots. 1" sensor seem to be perfect for that series. Otherwise lens gets way too big ...
With the exception of waterproof P/S cameras, I tend to agree with your statement.....

Canon 7D Mark II firmware 1.1.0 Available

greger said:
While browsing the website of the camera store where I have bought all my cameras in the last ten years, I found the Wi-Fi Adapter W-E1 available in mid September for $59.99. So why are other camera stores charging $450.00 more to include this with the body? Buyer Beware!

You go into the camera store, ask about a Canon WiFi adaptor for the 7D2, they look it up on their computer, and it tells them that you are looking for the WFT-E7A.... They do not know yet about the W-E1.... Never attribute to malice that which can be explained by stupidity :)

Advantage of non-Vibration vs Sony with Vibration reduction..??

I am not or have been interested in mirrorless cameras and most likely will stick to Canon for a while, and yet I strongly suggest you find someone who has the Sony camera that you had in mind and if he can allow you to test it, that would be even better.
My point is that using a stabilizer is not a matter of just stabilization, there are many factors that you have to take into consideration; and the most important of them - my opinion - is weight. Smaller cameras may have advantage in many respect depending on what you do, especially if you are a one-band man shooting a wedding video for few hours. Many stabilizers nowadays accept only (or work better with) smaller cameras and you may end up with limited options.
Speed and time to balance the gear is another one, especially if you have to mount and un-mount it few times during the wedding.

DXO *finally* tests lenses on the A7R II

bmwzimmer said:
You know why Sony has a higher sharpness score? Because the Canon stops down to f/32 while the Sony stops to f/22.

I'm not saying you're wrong, but how do you know that the sony wouldn't have a higher score even if the Canon went to f/22?

Their sharpness charts, to me, have such poor presentation that it's impossible to tell what the data are. Which shade of green of the thin line against a white background is darker?

Even if you click them, the charts are practically unintelligible. Which lens is sharper wide open rather than averaged over the aperture range? I have absolutely no idea. They should include a mouseover readout.

Their acceptance charts at least show some differentiation.

Real World Dual Pixel RAW in 5D MkIV? Not so useful...

sebasan said:
Do you trust this guy?

You can trust Tony to say a lot of things and show you some pictures.
Practical value not guaranteed.
Really every reviewer should be approached with the same skepticism.
(Especially in this case since none of the reviewers so far have demonstrated an understanding of DPRAW.)

Upgrade: 1Dx to mark II

Mario said:
Pleasant surprises: AF during Live View, it's fast, very fast. I can have my 200-400 on it, with a 2x extender, and flip in the internal 1.4x extender and in Live View, AF is still fast. Which brings me to the next pleasant surprise: the 1DXII seems to take extenders better than anything before. I never use the 2x extender a lot before as I could see it clearly having an adverse effect on IQ. With the 1DXII, that adverse effect seems way less, I now use the 2x extender a lot more. With the 200-400 and the 2x extender and the internal 1.4x in place, the IQ is still more than acceptable. This is now my preferred set-up in my garden hide. With this combination I am good for squirrels but also for the tiniest garden birds.

Hi Mario,


Something to try out. My 2.0 extender is only taking dust the last year. On 600mm I can use iT, but on the 200-400 I defenitely skipped iT. When back from Costa rica, I will give iT a try against on the 200-400.

Canon EOS M5 Coming in Two Kits, Including New Lens

unfocused said:
I know what you are saying Neuro, but another way to look at it is that Canon is very serious about the MILC market. They have seriously studied the market and very carefully balanced their investment with anticipated returns.

Certainly. I meant 'not serious' in the sense of not very invested from a product standpoint.

AA filter in the 5D mark IV

The 5D4 image RAWs also appeared soft in DPP 4.5 once I updated and was able to bring them in, not a whole lot better than what was on DPR to begin with. Not sure what is going on other than what I've speculated earlier. However, I'm positive the cause is not DPRAW as these are normal Raw files.

People should be getting this camera in their hands soon, so I expect a lot more follow-up re. this topic.

5D Mk4 Dynamic Range Analyzed From RAWs.

privatebydesign said:
chauncey said:
My bad...I often make the assumption that all descent photographers are adept at PS CC.

You are conflating a third aspect now. :)

DR is at capture, if your camera doesn't have it you can't get it back. In most shooting situations the cameras native DR is capable of capturing the scene DR.

The need for DR in the age of PS is unconnected. PS can't recover DR never captured, however good you are in PS.

The ability to get your intended output from the file you got at capture is unconnected to that file or the capabilities of PS.

To get your imagined output you need the input, DR, and the ability in PS. Unless you are happy with what you get OOC, and many people are.

Precisely.

PS comes into play as a replacement for wide DR if you plan is to composite multiple captures in order to construct a picture including levels outside the range of the camera I/O. One could just as easily ask "what relevance DOF plays in the age of photoshop".

And that third conflation is really bizarre.

5D Mark IV Diffraction Correction

hji1945 said:
szinski said:
I found this in the owner's manual (pg. 212):

With "Diffraction Correction", degraded resolution due to the low-pass filter, etc., is corrected in addition to diffraction.

So a menu option to disable the effects of the AA filter?

Will this work with a RAW file or only with JPEG?

Try DPP for converting CR2 files. With lesser cameras, Digital Lens Optimiser is there to claw back what's lost due to diffraction etc. It does a good job, but like any sharpening, it does it at the expense of noise.

What's Sony Up To?

The problem is that of all of the photography rumour sites SAR is the least judicious in screening out dodgy rumours, and instead shamelessly publishes any abject drivel they are fed as click-bait for the gullible masses.
SAR is 99.999% clickbait for the affiliate links, the dude that runs it is a total jerk.
...

To me it feels like nikonrumors is run by the same guy.

But sometimes this website feels similar in that the stories are about "What's on sale today".

Am I allowed to sing my little Coleridge somg here? :D pretty please?

5D4 Dual-Pixel RAW Image Microadjust comparison to AFMA posted at DPR

arthurbikemad said:
Only reason I play it down is people seem to think it will fix focus issues from head to toe, when the findings are not the case Canon will get bad press, but then they get bad press anyway haha, a mate of mine has been saying how he thinks it will resolve from nose to eye in portraits, I've said I think you will find its more like mid eyelash to tip.

DPRAW can give you focus correction from head to toe or nose to eye or any amount that you want, because you are in total control of the amount of correction available.
Right now all these ridiculous testers are just complaining about their own ignorance, setting up the camera to have a fraction of an inch of adjustment range and then whining about it.
You basically can't use the feature at 85mm f1.4, but maybe a lot of people would be better off if they did stop down a bit.

Ironically it's going to be people with zoom lenses and cheaper lenses who will benefit most.
Hopefully that fact will push the technology down to entry level bodies sooner rather than later.
