When (and if) does a "gold" colored flash diffuser make sense?

I've seen there are "gold" flash diffusers like the ones from sto-fen that are supposed to give, surprise, warmer "sunset-like" light. Since I couldn't find any decent reviews...

... does anyone use this kind of diffuser, when does it make sense (broad range of situations or only as a very special effect)? Any sense buying this over flash gels except that gels are a hassle to mount to the flash in addition to a diffuser?

6D pattern noise compared to 5D2, the info you won't get from DxO

Got to play with one a bit at the shop today, shot some dark frames and pushed them as i usually do to better visualize the pesky noise patterns.

The 6D is considerably improved over the 5d2 and even 5d3. Although the total amount of dark level noise is not so greatly reduced, the subjective annoyance of its patterning is noticeably less.

5d2 could produce some fairly harsh noise lines (hor. & vert) in shadows at 100 ISO, they soften a bit from random noise at 400 ISO and up.

6d, at the same ISO settings, produces far less obviously structured noise lines. THIS IS A GOOD THING! :)
Canon has actually made some significant improvement in this area over the older cameras!

6d's overall noise is more random and uniform, tho still exhibits some fine vertical stripe structures at 400 ISO, similar to 7d's low iso noise but not as severe. Overall there is still some coarse but smooth transition variations in horizontal and vertical axis, almost like large blotchiness. This would not show up on large prints anywhere near as bad as 5d2 or 7d noise stripes.

6d's subjective total noise at 400 iso is similar to 5d2 at 100 iso. And the 6d's noise would clean up better with NR software.

6d's high iso performance is impressive!
I could print a decent 6x9" from a reasonably exposed 25600 iso shot! (larger if not too fussy)

So, altho 6D's dynamic range will not be significantly better than 5D bodies at low ISO, its raw files should provide more post-processing leeway because of the reduced severity of patterned noise. Its extra performance at high ISO is a definite bonus.
Fussy shooters who do a lot of post-processing should definitely consider the 6D over either 5D body if low ISO performance is critical to their work.

SoNikon sensored cameras still do blow the 6D into the weeds with far cleaner low ISO data.
Hopefully Canon's (soon to be released?) next generation sensors will further improve on this dark/read noise issue.

As it is now, I am very tempted to sell my 5D2 to fund the 6D, it's that much more usable to me.

How to produce circular flash reflection in eyes?

I've got some flashes and conventional diffusers, i.e. the sto-fen type. But I'm annoyed by the ugly flash reflection in the eyes, so currently I'm looking for a softbox (larger square "studio-like" reflection) and/or some means to produce a circular reflection.

The best I could come up with is this type, does anyone else the conventional rectangle reflection is ugly and has another solution (or something home-made)? http://www.amazon.de/D%C3%B6rr-PRO-4-Diffusor-Canon-580EX/dp/B001BN4T9S/ref=sr_1_2?ie=UTF8&qid=1357378741&sr=8-2

lens for a lightpainter

Hmm,
its Gotta be extremely sharp at apertures beyond f/5.6

Weather sealed coz I'm gonna be using it in snow,dust,sand and what not

Tilt and shift functions are welcome( I would love it but I doubt it'd be possible)

More realistically an ultrawide lens with a good zoom range

Ability to change aperture mid exposure

Easily available ,no hunting on eBay etc

I will be using it on a 7d so it won't be ultra wide after all

Accepts filters

Well that's pretty much what my impossible list is no lens can be everything at once so sharpness, weather sealing and ability to change aperture gets preference pretty much in that order I hope you guys can bear with me

Thanks in advance

Sensor dust on a new 5D Mark III

I have heard that sensor dust is present sometimes on new cameras, and in the case of a new 5D Mark III I received today, that statement holds true. Using a blower made no difference, so the sensor will have a wet cleaning soon. This is the third consecutive body (first two were Rebel T3i models) with non-blowable sensor dust right out of the box. My question is whether many of you forum members have had similar experiences. I must say that not being able to use a new camera right away does something to take the skip out of one’s step.

The grass is greener?

Wow, I really respect this guy as a working professional and he is saying DO NOT buy a D800, D800E or D4 because they all have serious AF issues.
Lot's of owners chiming in with similar stories.

He basically says the only way he can get reliable results in MF in LiveView with a tripod in the studio.
This is exactly what I was worried about when I switched to Canon last year.
Seems my fears were real.

http://blog.mingthein.com/2012/10/27/nikon-d800e-midterm-report/

Now I just need to find some new glass that makes the 5D MK3 sing and I'll be happy...

600 ex -rt sticky wheel syndrome

I have 3 of the 600 ex rt speedlites. last night as I was gearing up one of the units the adjustment wheel became really stuck almost impossible to move I had to jam my fingernails into the grooves to rotate it.
the other 2 units units seemed stiffer than usual. I took them to Canon service in Irvine 53 miles away,
the intake receptionist took the bad one back to repair and came back said it was normal. Well that made my day, I told the girl to try the other unit. duh...
A speedlite you can't adjust is useless. I think the lube used is gumming up the wheel as it was really cold here and maybe the heat from the flashing degraded the lube. either way its a problem especially for a $550 speedlite. My other two units are exhibiting bad behavior as well.. I really think the cold weather is affecting them..

IS sound probleme 100 2.8 L IS USM Macro with my EOS 5D MK III ? [SOLVED]

Hello,

I have observed the following effect when I use the 100 2.8 L IS USM Macro with my EOS 5D MK III.
If I have start the IS, the IS motor sound is VERY present, but after one minute (continuous operation),
sometimes longer, this sound disappears. (see this MP3: http://www.space-observer.de/CR/5DMK3.mp3)
If I use the same lens with my EOS 50D the IS sound is always very quiet.
(see this MP3: http://www.space-observer.de/CR/50D.mp3) .

Has anyone ever notice this effect with the 100 2.8 L IS USM Macro in combination with the EOS 5D MK III ?

ciao

<strong>Via Lens Rentals


</strong>Roger Cicala from <a href="http://www.lensrentals.com" target="_blank">LensRentals.com</a> has posted his first resolution tests of the Canon EF 24-70 f/4L IS.</p>
<p>He has compared it with the EF 24-70 f/2.8L version 1 and 2, the EF 24-105 f/4L IS as well as the Tamron 24-70 f/2.8VC. All of which will probably get your consideration in a very crowded focal range.</p>
<p>At 24mm, the EF 24-70 f/4L IS is the second best performing lens behind the EF 24-70 f/2.8L II. Mind you, the results are all pretty close. It does look like Canon’s MTF chart of the lens holds up against the others.</p>
<div id="attachment_12557" class="wp-caption aligncenter" style="width: 585px"><a href="http://www.canonrumors.com/wp-content/uploads/2013/01/ef2470f4is24chart1.jpg"><img class="size-full wp-image-12557" alt="EF 24-70 f/4L IS at 24mm Resolution Comparison Chart" src="http://www.canonrumors.com/wp-content/uploads/2013/01/ef2470f4is24chart1.jpg" width="575" height="119" /></a><p class="wp-caption-text">EF 24-70 f/4L IS at 24mm Resolution Comparison Chart</p></div>
<p>At 70mm, none of the lenses are as sharp as they are at 24mm. However, the EF 24-70 f/4L IS is again the 2nd best performing lens by a small amount.</p>
<div id="attachment_12558" class="wp-caption aligncenter" style="width: 585px"><a href="http://www.canonrumors.com/wp-content/uploads/2013/01/ef2470f4is70chart1.jpg"><img class="size-full wp-image-12558" alt="EF 24-70 f/4L IS at 70mm Resolution Comparison Chart" src="http://www.canonrumors.com/wp-content/uploads/2013/01/ef2470f4is70chart1.jpg" width="575" height="120" /></a><p class="wp-caption-text">EF 24-70 f/4L IS at 70mm Resolution Comparison Chart</p></div>
<p><strong>Part of Roger’s Conclusion


</strong><em><b>“</b>Obviously this hasn’t told us a thing about autofocus accuracy, bokeh, or a dozen other things that have to be considered when choosing a lens. Just like you, I’ll be waiting for more complete reviews to tell us about that.</em></p>
<p><em>On the basis of this information, though, I’m . . . well, I don’t know what I am. This is a good lens, but I at the price point I’d probably prefer the f/2.8 of the Tamron VC to the new Canon’s f/4. The macro feature is nice and will certainly pull some people towards the Canon.”</em></p>
<p>Roger also notes that there was quite a bit of variation at 70mm between the 22 copies they tested.</p>

Nikon sells a lineup of crop primes, why not Canon?

So in assisting a friend search for new lenses on her D90 I advised her to check out some decent economical fast Nikon primes. These are crop only lenses akin to EF-s for Canon. I am curious as to why Canon hasn't tapped this market. I really like the Nikkor 35mm 1.8 DX for a 'normal lens on her D90. Kind of Nikon's equivalent to a Nifty Fifty.

But to tell the truth, as a lifetime Canon user,other than owning a Nikon film camera in the 80's it was my first foray into shopping for Nikon products and I truly found the overall line lacking in variety and multiple pricepoints. It's either super expensive or dirt cheap.

5D mark iii & off-camera flash

Hello Everyone
I have been searching the forums for answers to these questions, and have found variations but not really what I was looking for, so I am hoping some one can help me out.
I recently got a 5d Mkiii. Previously was using my 60D to fire my 580 ex II remotely off camera (I don't really like having flash on camera if I can help it). Obviously with the Mkiii I can't do this, so I was weighing a few options... esp since I would like to start doing multiple flash set-ups... so this are the options I have been weighing...

A) grab an ST-E2, or decent equivalent (help), us that, and then add either another 580 or 430 down the line
B) sell my 580 and get two Yongnuo 565s for the same price, and prob even the 622s to control
C) some sort of mixture of the above... but I am not sure how that would work.

If I am not mistaken, each Yongnuo requires its own 622 to be controlled, correct? But with the canon line I get one ST-E2 and it will fire flashes off camera without receivers? And if I have a 580, should my second flash also be 580, or will a 430 suffice for fill if the 580 is the main flash?

Mostly family portraits, etc... should have mentioned that!

thanks very much!

<p><strong>Not hearing much…

</strong>CES starts next week and with it a lot of camera companies will be launching consumer level products. Last year Canon launched the PowerShot G1 X for CES and that was about it.</p>
<p>No media events have been planned by Canon for next week. 99% of the time if Canon is launching a significant camera, there is some kind of media invite to showcase the new cameras.</p>
<p>However, when lenses are announced, that is not always the case. There was no media invites when the EF 24-70 f/4L IS and EF 35 f/2 IS were announced.</p>
<p>We’ve heard that two, <a href="http://www.canonrumors.com/2012/12/announcement-on-january-8-2013-new-lenses-cr1/" target="_blank">possibly 3 lenses could be announced on January 8, 2013</a>, but we have not received any confirmations from known sources yet.</p>

Canon 5DIII and Media Cards...

I know that this is an old discussion topic...but I just am trying to clarify things for my (old) brain.
Regarding how the 5DIII records to to the two different card types, my readings and my own findings with my
camera tell me that:
1. If I write to the CF Card ONLY the write speed will be native to that card (with or without an SD card in the camera). i.e. a 600X card will record at or about 45MB/sec.
2. If I write to the SD Card ONLY the camera can only write up to 20MB/sec regardless as to the write-speed of the SD card that I put in the card slot. i.e. If I put a 600x SD card in the slot with 45MB/sec rated speed, the Camera will only be able to write to that card at 20MB/sec.
3. If I have a CF card and an SD card in each slot, both rated at 45MB/sec and set the camera to write to both cards simultaneously, in the same image type to each card (i.e. RAW, Jpeg, etc.), when I record an image, both cards will be written to at the slower, 20MB sec rate.
4. If I set the camera to write to both cards with different imaged types (i.e. write RAW to the CF and Jpeg to the SD, or visca-versa the writing will take a longer time than if the camera was set to write the same type of image to each card as in #3 above.
Question:
What is the fastest CF card that the camera can write to at the cards native write speed? i.e. how fast can the camera write to a CF card?
Any input to confirm 1-4 above or to increase my understanding of my camera would be welcome...I think I have it correct..but I could be wrong.
Thanks.

Oops, did it again !

So there I was, nice looking deal on a second hand Canon 17-40mm lens, down to the shop, the lens offered just the right focal range for me on my 6D, but the lens looked well used and had loose rings... Asked how of tern they had them in, quite often came the reply, what about the 16-35 I asked, oh we don't get many of those second hand... Can I try one please ? Out comes a 16-35mm II, onto the camera, snap, out comes the credit card for a new lens. Naughty me. ;-)

I'm guessing many of us do this with camera equipment, what's your tale and did you get into trouble with your significant other half ?

Anyone still using a 20D?

I have a 20D, and am waiting to buy a 5DMkIII this year if I can save up a bit. Should I simply assume the 20D is obsolete? I still really like it, and 8mp seems nice enough for some things that won't be blown up over 5x7 or so. Is anyone still shooting with this older camera, or is the tendency to simply let it go? It's such a dear friend....

Canon SX 50 v. Panny FZ200; is it just me, or does Canon smoke it for IQ?

Is it just me, or does the Canon not smoke the Panasonic on image quality in this review? The reviewer is touting the constant f/2.8 aperture throughout it's 24x (600mm) range, and granted that does give nicer background blur/subject separation, and of course that can give higher shutter speed and all...BUT. He never talks about the IQ differences in his own comparison shots.

http://www.cameralabs.com/reviews/Panasonic_Lumix_DMC_FZ200/

It just seems like from his shots anyway that the Canon gives much sharper images.
