Canon EF Zoom Lenses / Re: Canon EF 16-35mm f/4L IS USM
« on: September 02, 2014, 11:58:33 PM »

Hmm, must be something with my site - I'll have to take another look at it tonight.  The shot that's still showing is the 16-35 f/4 IS.

Ok, thanks - is that about as sharp as most sunstars are?  What f-stop was this shot taken at?  Thx again.
It should be fixed now, and that shot was taken at f/16, specifically to check out the sunstar.  Here's another example @f/16 & 24mm.  Ugly photo, but again, it was just to test out the sunstar/flare resistance:

One thing I like about this lens is it requires minimal post processing to deliver an image without distracting artifacts.  You can't say that about most Canon UWA lenses.

One thing I don't like as much is the sunstars, at least from what I've seen thus far.  The rays look thick and not as commanding as the sunstars of the EF 16-35mm f/2.8L II.  Of course that lens requires some significant post work to remove CA, add sharpening and is not as sharp in the corners at wider apertures.  The best one I've seen of the 16-35 f/4 IS thus far is here (16-35 f/4 IS on left, 16-35 f/2.8L II on right):

I have to say, there have been times that the 16-35 f/2.8L II has given me sunstars that were unexpectedly long and in ways intruded into the rest of the picture - but some of those shots actually turned out more interesting as a result of the impressive yet not purposeful sunstar.

So, Canon Rumors members... Who can impress me with some bombastic sunstars from this lens?
Ruined, the first post in this thread shows a sunstar comparison between this lens and the TS-E 17 f/4...but the links were broken until just now. 

Also, I agree with the post processing - if you look at the last shot I posted, it would have been a CA nightmare with the 16-35 f/2.8 or 17-40, but with this lens, there was hardly any CA to remove.  The big deal with that is that I exposed to the right to get the highlights, so the shadows had to be punched up quite a bit.  With other lenses, I would get some nasty artifacts around the highlight edges from the removed CA.

The vignetting and distortion are a bit higher than I'd like at 16mm, but DxO & ACR handle things quite well.

Overall, I'm very pleased with the lens, though I have yet to make much use of the IS.

Hey mack,
Links still appear broken to me except one sunstar shot (#8520).  Not sure if that is the 16-35 or not - thx.

I also still shoot film :)

Film...???

Was that something they used before Exmor?  ;D
No, but you can replace your sensor each time you replace your memory card (err, roll) and full frame is pretty much standard.  The capacity is a bit limited and without an LCD on the back, it's a bit harder to use.  Also, the photos have to taken to a special person for post processing and they give you strange things printed on paper or in little white holders in exchange.  PhotoCDs are available from some places.  The cool part is that you don't have to worry about post or printing stuff yourself - unless you like smelly chemicals and dark rooms with red lighting...

As for the topic itself, the biggest complaint I hear from my Nikon pals is about the lenses.  They don't feel like Nikon's lens selection is as varied or up-to-date as Canon and they don't like the pricing, especially for the 800mm.

I use the SD card slot for two reasons - 1, in case I forget to replace the CF card after putting it in the card reader, and 2, to copy a day's worth of shooting to the SD card when traveling as a back up.  Writing to both cards just gets too slow for my tastes.

Try this - go into the Live View menu settings and then into the Silent Live View shooting mode settings. Change the setting to “Disable” and it should work.  The first two silent Live View settings also disable the use of flash and screw up the older TS-E lens and extension tube exposures and I think it screw up the the cable release function as well.
Great, will try that tonight. Another thing I noticed was the "Exp. SIM", what is that? I don't know if the subject I was shooting makes a difference but it was the Brooklyn Bridge, late at night. So low light conditions with the bridge lights and Manhattan skyline behind it.  Thanks
That's exposure simulation - see the details below:
Ok, should I disable it then?
It depends on what you're wanting to do - there's really no right answer.  I generally leave it "Enabled" so I have a general idea of how the shot will look (particularly in M mode).  When I shot at night, though, I'll set it to "During" so the screen is brighter which helps me manually focus and set tilt/shift on those lenses.  I can quickly push the DOF button to get the simulated exposure view.  I always rely on the histogram (pre- or post-shot) to get accurate exposure (or expose to the right exposure), though.

My favorite one I've taken - a really pissed off looking mime who creeped me out and the amateur paparazzi behind him on Royal Street in New Orleans.  Also, no comment on why I was on the wrong side of the police barrier ;D:

When I shoot in live view I disable auto focus... so it is more responsive to the shutter button.  When I heard your problem that was the first thing that came to mind, but I'm not sure that is actually what is wrong.  Good luck.
When you say disable auto focus do you mean switching the lens to MF or do you mean turn the camera to Manual from any other mode?

Disable at the lens.
Setting your camera to back button focus achieves the same effect as it doesn't [slowly contrast-]AF when you press the shutter...

Dear Friend Mr. Mackguyver.
From Your great Imaginative words " So, let's fast forward 10+ years to where we have achieved the perfect sensor.  It ( I ) can do the following:"
Yes, Next 10 Years , I will be 75 Years Old man with Old  Heart
1) I must have 2 Transplant of New Young Eyes to see the Perfected Photos which created by the Perfected Sensor.
2) I must have a new Heart Transplant for long  photographic trip  with the new camera with New Perfected Sensor---With out died because of heart attack---For Long Walk and -----
3) I might require a Young, Strong and Beautiful Wife to  help me carry the heavy weight  Lenses---No , New DSLR Canon EOS-M MK VI are so small like the Match Box---I do not worry about Weigh of Camera Any more.
4) my  NEW WHEELCHAIR ( When I am 75) can go any where  and fly like hovercraft.
BTW, I forget the last requirement
5) one of my body part must need a new transplant too---Because of new Young, Strong and beautiful wife---Ha, Ha, Ha---My Two legs, Which I need to walk fast , to catch up  with her walking speed.----NO, I not Dirty old man, But Still sexy Old Man.
 Just want to have FUN, and Talk with you, Sir.
Have a great work week.
Surapon
Surapon, thank you for your funny post and for making me smile - as always!  I'm feeling very old today (at 37) with many serious joint problems that will likely require surgical replacement, so thank you for the laugh :)

OMG, the levels of philosophical BS predicting the detriment of creativity brought on by better tools is amazing.

art is the product of the artist and their tools, expanding either one increases the possibilities.

(not a thread worthy of more than these words)
Okay, I'll admit it - I was trying to exaggerate all of the theoretical BS posted around here to the greatest extreme possible.  Given that I'm never sarcastic, I'm sure no one expected that :P

At least we've got lots of rumors to talk about these days, but I was curious to see how people would respond to this post...

I have used flip locks in the past and do not consider them suitable/trustworthy for tripods and mono pods. Both the Gitzo and Sirui twist locks are far superior and much easier to use, as well as being MUCH more secure.
As a complete inverse to your experience I have used twist locks in the past and find them slower and less trustworthy. I have used flip locks now for 15 years and wouldn't consider going back to twisties. Too slow when the pressure is on. What exactly is it that you find makes twist-locks MUCH more secure?

I've had twisties "sink" but never had a flip-lock sink under weight. Another advantage of a flip-lock is you have a visual confirm of the full-lock position. With a twistie, there is no visual cue. I've had legs on my twist-lock Gitzo tripod sag unexpectedly, but never my big flip-lock Manfrotto 075B. I'm a flippin' fan!

-pw

The Manfrotto 075B is indeed a pretty sturdy piece of kit though do remember to check the tension of the flip locks periodically! A couple of years ago during a Gear evening a colleagues 400 F2.8 + 1D3 required catching when two of the locks on his Manfrotto 075 started to slip - the twit hadn't tightened them for a while - so his fault.
As to Gitzo locks - I have an old Gitzo G1329 Mk2 (requires much more twisting force than my 3 newer ALR models), my Grand Nephew can and has tightened these leg locks sufficiently to support my 100 + Kilo weight, it's his 3rd birthday very soon! Was the Gitzo you tried faulty?
Yep, those flip locks on the Manfrotto are great until you forget to tighten them.  I was shooting some sports last year when I thought my monopod was sinking in the mud - nope just loose locks.  Luckily I had the wrench in my car.

I returned to an old favorite place this morning called South Swamp, almost 3 years to the day of my last visit and I'm happy with the results:

That's a great shot, looks  menacing.
Thanks, it's a really interesting and yes, menacing place.  Nothing too scary today other than some deer & biting flies, though :)
