Canon General / Re: Does Canon really deserve this?
« on: November 23, 2014, 11:54:28 AM »
I browse this website quite often since 2012. I have never seen so many negative comments about Canon these days in comparison with before.
Does Canon really not satisfying its customers lately or is it that there are new members in the forum who like to put down Canon in comparison with other companies?

Yes, yes and don't forget trolls who do not even own Canon equipment.

I may be the only guy posting here under his real name, but for all I know, this could be two dudes in their underwear and their 55 sock puppets each deployed to do battle against each other and one of them started the war with this post.

EOS Bodies / Re: EOS 7D Mark II: More High ISO Samples
« on: September 27, 2014, 08:43:30 PM »
I'm impressed too by the results, at 3200 iso images look really clean ! and at 6400 it doesn't look bad too, i can't wait to have it...

ISO 3200 was very good - almost felt like I was viewing an ISO 200 photo, but 1/3 stop later, there's lots of noise IMO.

Just release the 24 mm f1.4A. You know you want too.

Yes please.

When was the last time you saw a popular Zeiss lens come from Germany?

Yet today in America (and perhaps Asia too?) it is the Zeiss name that is more widely known than Schneider-Kreuznach.


Amusing since Canon/Nikon customers believe that their brand's cameras and lenses made in Japan are a sign of better quality.

The Zeiss name is better known for several reasons:

1.) because of that company's marketing efforts. Not all marketing is deception and smoke & mirrors. It wouldn't hurt Schneider-Kreuznach to mount a print and internet campaign to promote these lenses. They might ought to suck up to sites like DPR.
2.) The Zeiss name accidentally got a boost among Canon shooters when it was discovered the discontinued Contax Zeiss 21mm could be adapted to EOS and provide much better uniform sharpness across the frame than their Canon WA & UWA lenses of that time period.
3.) As far as I know, Schneider-Kreuznach has been a niche player in the USA DSLR lens market with a few T/S ad Shift lenses with no evidence that they are any better than Canon/Nikon's own T/Ss (refer back to #1) and more of a force in MF and large format where most Canon/Nikon users could a give 2 cents about.
4.) Schneider-Kreuznach ought not to do the same thing they have done with 4/3 i.e. announce, then disappear (although I do not know the exact nature of that announcement). If they are going to come into the market with a price lower than Zeiss' Otuses (the presumption here being that Otus is the competition), they should announce the prices now and freeze Zeiss sales. Unless there is a translation issue in the English version announcement, the suggestion is the lenses have been developed already - the 85mm for sure since they had one displayed at Photokina.

To the guy complaining about manual focus, why would you want AF to get in the way of achieving critical focus after spending all of this money?

there isn't a 35mm Otus.

There will be. It seems like Zeiss likes to roll out their lines one model at a time. Let's hope Schneiders are priced in-between the ARTs and the Otuses.

I am waiting on one these manf vying for the high end to release 21-24mm version.

Will I have to wait until Photokina 2016 for the Otus 21mm?

Do I but the Sigma 14-24mm OS which takes 82mm filters, although all my other lenses take 77mm filters, and also lose 13° of angle of view compared to the Canon 16-35mm f/4? I think not.

I'm sure these lenses will be good for others, but I will skip them for now.

Well, yes, but it's easy to get excellent lenses in the 24mm-35mm range. 

35mm yes, 24mm not so much.

Lenses / Re: Canon EF 50 f/1.2L Goes Missing at Canon Germany
« on: July 31, 2014, 01:56:10 PM »

Introduced in 2007, the EF 50 f/1.2L has seen its share of controversy due to a design that can lead to focus shifting in certain situations for a lot of photographers. </p>


I think the controversy began when folks attempted to use the lens in ways not consistent with its design.

EOS Bodies / Re: High Megapixel EOS on the Way as Mentioned by Canon
« on: July 23, 2014, 03:20:20 PM »
Unlike many Google translations, this one is a bit more readable...

I note the comment that the 16-35 mk2 was good for APS-H ;-)

The multiple aspheric lens surfaces allow them to ease some of the compromise between reducing distortion and field flatness. The two front lens elements make quite a significant contribution to this and will likely be seen again in new ultra wide zoom designs.

I still want a TS-E14 though ;-)

Actually, I was going to ask someone to translate the translation. :)

I have often made the assertion on DPR that the 16-35 II was designed for APS-H because 1.) it was introduced alongside the 1D III and 2.) the edge/corner performance obviously was not up to FF standards MP counts of the time period notwithstanding. Of course, I was criticized for this viewpoint (which I still hold). It looked to me like the interviewer made the reference to APS-H but the interviewees did not touch on the reference.

EOS Bodies / Do what?
« on: May 28, 2014, 07:00:56 AM »
Bare in mind that the 5DIII resolves nearly as much detail as the D800. It's only the top end optical resolution of a few of the worlds sharpest lenses which can allow the D800 to out resolve the 5DIII and even then, there isn't much between them.

1.) I have both cameras, and the D800E clearly produces more of the fine detail that renders an image more realistic (if all of the resolution-saving techniques are used and the image isn't bludgeoned to death in PPing).
2.) This resolution differential can clearly be seen when using any lens in my bag and most Canon, Zeiss, Sigma et al lenses in current production.
3.) This resolution differential can clearly be seen in downsized images (as small 1800x1200 px for instance).
4.) Many folks "clearly" do not care about or even see the fine details in the natural world.

Now, whether or not "clearly" equals "nearly" is a probably matter of observational skills.

Zeiss announced the first ZFs, 50/1.4 ZF & 85/1.4 ZF, Jan 1 2006, and then announced 4 more in Oct 2006 for Photokina, the 35/2 ZF, 25/f2.8 ZF, 50/2 makro ZF & 100/2 makro ZF according to news stories over at DPR. If Zeiss follows the same pattern and announces an Otus 25/2.x at Photokina, I'll soon be buying my first $4k+ lens. Sure, no guarantee that the same pattern will emerge but a fellow can dream. Zeiss may be more cautious rolling $4k lenses than they were releasing $500 to $1k lenses  back in the day.

I think the news is out on the Sigma 50 ART, no cigar for competing with Zeiss wide open.

Third Party Manufacturers / Re: Sigma 50mm f/1.4 Art Gets Reviewed
« on: April 06, 2014, 12:43:06 PM »
Sigma's famous statement: it wasn't looking to surpass Nikon and Canon, but rather the Zeiss Otus 55mm f/1.4 has a way to go judging by the graph in the review. I would have expected the FF graph to look like the 7D graph based on this bragging. The Otus' whole thing is sharp corners at f1.4. That's expensive to achieve.

You don't seem to know how to read the graph or what a typical graph is. This lens actually has LESS falloff in resolution between the center and corners than the Zeiss Otus, and 3 times less falloff in corner resolution than a typical competitor.

SLRGear hasn't reviewed the Otus, your statements are baseless.

SLRGear brought up the Zeiss in their own comments.

We don't have a true side by side test yet.  Based on these results, I still expect the Otus to be sharper, corner to corner at f/1.4.  To get anything close to a side by side test, the Sigma 50 A is similar at f/1.4 to the Sigma 35 A in the SLRgear test.  I actually think the 50 A is a bit better. 

But here is a link to the Otus vs the Sigma 35 A both at f/1.4:

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=917&Camera=453&Sample=0&FLI=0&API=0&LensComp=829&CameraComp=453&SampleComp=0&FLIComp=0&APIComp=0

The Otus is clearly sharper corner to corner when compared to the Sigma.

So, yes, the Sigma is blasting Canon and Nikon.  Excellent, IMO, but it likely is going to slide in slightly behind the Otus, which is nothing to sneeze at.  Considering AF, price point, etc....the Sigma will likely end up in more bags than the Otus.

EDIT---just checked Lenstip.com.  They have the Sigma 35 A and Otus 55 very similar at f/1.4. 

If the Otus is better than the Sigma 50 A, I doubt it is by much.  This review is a very good start for the Sigma 50 A.

Could you post a link to the lenstip.com comparison where you are getting your information? Sight unseen, I would bet the house the Sigma 35 is nowhere close to the Otus 55 in the corners @ f1.4 which is what my original point was and still is and is regarding the Otus @f1.4. SLRgear will confirm my assertion once they review the lens. However, comparing a 35mm to a 55mm lens dumps a disadvantage on the wider lens. Even a comparison of the 50mm ART and 55mm Otus will give a slight advantage to the 55mm lens (all other things being equal).

Stopped down a bit, the other competitors will catch up, then one has to decide if the other Zeiss characteristics are worth $4k.
