I just discovered a hot pixel in a few photographs. I did a pixel remap and it's gone :)

So far I didn't do a remap on the mkIII. I only bother to remap hot pixels if they show up in photo's. However I've so far remapped the 40D I had, my 5DMkII and now my MkIII. Pixel remapping is a great feature.

is that they are not able to make a reliable, consistent, AF, on their lenses for Canon.

And yet I've been using my Siggy 120-300mm f/2.8 OS hard for nigh on three years, shooting birds, aircraft, fast bikes, moto-x. touring cars - all the stuff that stresses an AF system - and the AF has not missed a beat.

So that's some first-hand experience for you, right there: apparently they can "make a reliable, consistent, AF, on their lenses for Canon".

Same story - over a shorter period (but still over a year of hard use) - for my 70-200mm f/2.8 OS.

Siggy users aren't idiots, nor or they inherently easily pleased: we use the lenses because they're bloody good at everything they need to be good at.

It seems that people generalize on Sigma lenses. Sure, there are people that bought Sigma lenses with AF problems. That does not mean that everybody has problems. I use a 50Art and it is spot on. It is obvious that on Internet you read more complaints rather than praises. Not saying I ignore the problems that others have - not at all - , but statements should be more balanced.

I covet my Sigma 20mm f/1.8 - a unique lens. This shot couldn't have been taken otherwise (it's on the limit of everything).

The Opteka branded version of the Samyang come with a 2x teleconvertor, for those occasions when 1300mm is just, well, too short...  :o
£247.51 inc. P+p

That makes it f/32 at the long end  ??? ::)

I now realize what a bargain I turned down recently. I was offered an Olympus OM Zuiko 1000mm f/11 at the camera repair shop when I had my OM-10 serviced. Only £1000 including original case and key.

I already have the adapter...

The Samyang 650-1300 is a lot cheaper and much more versatile :D

€ 329,00 in the Netherlands

What I'm saying is that I don't think the lens is fooling the camera at all.  It's just telling the truth—that it is an f/4 lens, albeit not at that particular zoom setting.  :)

Are you in politics by any chance?  ;D

I notice that the 14-24 f/4 is not rumored to be an "Art" lens. 

I'm waiting to see the quality level of the lens when and if it's announced.

'C' for contemporary?

P.S. This is just my opinion and I have no problems with people finding a valid use for the popup flash. If you think it is absolutely critical to your work then I'll respect your point of view on the matter.

Fortunately it is the same opinion as many others - including Canon  ;)

I'm putting money on the 7DII not having one.

Given that it is likely to be an aps-c camera, the smallish prism leaves room for a flash to fill up the room given by the professional bulge on top of the camera. So I think it will have the popup again.

On this topic (an a little off it as well), please recommend a little external flash that I can use for fill-flash on a 5D series body when traveling. I currently have a Metz Mecablitz 48 AF-1 that's great but way too big for that purpose.

The 270EX II is relatively small, sits low on top of the camera, and has some bounce capability as well. Uses 2AA batteries. Obviously, it suffers from the same issues as a pop-up flash - not very powerful and close enough to the lens that redeye can be a problem. But if you don't want to pack a 600EX-RT, it's small enough to carry easily when you might just need a little light.

Cool, I was looking at the Metz 24 AF-1, but it doesn't have high speed sync which is a deal breaker for me. How about the 270EX II, does it have HSS?

If you have a camera that has external flash control (e.g., 1Dx, 5D Mark III, 5D Mark II), you can set HSS on the 270EXII through the camera menu. Of course, depending on how high you set the shutter speed, you will cut down on the range significantly.

Thanks for your help. As you can see in my signature, my Canon bodies do have that ability so the 270EXII has now made it to my shopping list  ;)

Stofen also makes a flash diffuser for the 270EXII in case you want to use it with the bounce feature. http://www.adorama.com/SFOMEV.html

Thank you, yes I will probably want that (I have Stofen diffuser for my Metz, too).

24mm f/1.4 A $1100?

Please anyone, what was the introduction price of the 35mm?

If memory serves...

$899 for the Sigma 35mm f/1.4 Art
$949 for the Sigma 50mm f/1.4 Art

- A

Thank you, let's hope it's a bit more in line with the previous releases and that the price goes down a little too in the first few months.

I thought ring lights were for macro stuff where the subject is virtually pressed against the lens and just getting any light on it can be a challenge?

Have you ever looked at studio strobes? You get ringlights from all brands, and they aren't excactly useable for macro work.

I think you're talking about something that falls under the category of "off camera flash" much better than "on camera flash" which is the subject of this thread.

On-camera.

Fantastic, have fun with that on your next vacation.

What cracks me up is "It is extremely compact, lightweight ...."  ;D ;D ;D :o

Out of curiosity, what does the EXIF tagging show for the f-stop?  From what I've seen when working with MF lenses, I'm fairly certain the lens can't lie to the camera about its wide-open aperture, or else every shot would be underexposed by a stop.  But perhaps it could get around that by lying about every setting equally.  If that were the case, wide-open shots would claim to be f/5.6 at the long end, even though they really can't be.

First of all, the EXIF data is always correct.  But somehow third party lenses have had a workaround that bypassed the f/5.6 maximum aperture limitation for many years.  I understand that the trickery is not so much about metering as it by bypassing that limitation.  Magic Lantern software also can bypass that same limitation for all lenses, so it obviously more of a software limitation than it is a physical limitation.

After studying the lens protocol, I think I get it.  The camera asks the lens to report its maximum aperture, but that's the maximum aperture for the whole lens, not for the current zoom setting.  When the camera sends a command to fully open the lens, the lens reports the actual aperture.  I'd imagine that the check to decide whether to autofocus or not is based on the maximum aperture reported by the lens, rather than the aperture that the lens reports when the camera tells it to open all the way at the beginning of focusing.

So as long as the lens says that it can open up to f/5.6 or wider, even if it really fails 100% of the time in practice, the camera will make the attempt.

With that said, I only spent about three minutes looking over the lens protocol, so I could be wrong.

Of course the lens 'fools' the camera to think it's f/5.6. This is similar to the 'tape trick' on 'reporting' teleconverters or using a 'non-reporting' teleconverter to AF on non- 'pro' bodies even at f/8.
