Lenses / Re: Anyone receive 11-24 yet (or shipping notice)
« on: February 28, 2015, 09:01:38 AM »
I love my 8-15, but I hate the lens cap.  It just doesn't stay on.  I hope the 11-24's is better.

I put tooth sticks behind the buttons which have to be pressed to separate the two parts of the hood/cap  of my 8-15, this way they can not separate unwanted and of course never did. I always shoot without Hood and remove them together. If i want to sell the lens, it can easyly be removed

maybe this would help you as well

A look at the dimensions and the complexity of this lens shows, that it's at the limit of what can be done at all. 11mm at 2.8 might sacrify lots of IQ, beside price and weight.

2nd point is vignetting. If there is lots of vignetting, then the lens is maybe T3.0 in the center and >T5.0 in the Corners. Vignetting correction just pushes the darker areas. Bad example here is the 24 1.4, which may be a 4.0 lens in the corners, just with more coma and softness. So it may be more important to see how much vignetting this lens has than to complain about the max aperture (=transmission in the Center).

There were no substantial or tough questions at all. No word about how long the outdated 500nm prozess will remain, why they have so much more readout noise than Exmor etc and nothing about any week points. The journalist fears to no be invited anymore, and gave a Marketing platform for the executive or was just to week personality to ask more tough, just allowed the executive to hide behind politeness.

And to be unpolite, the 5ds and 5dsr are in no way revolutionary, not even evolutionary, just more megapixel. That is what we see since the beginning of digital. They just catch up with the processing power of the 1dx, which is towards the end of life. This proofes that Digic 6 is no real improvement or that there is another bottleneck in the dataflow.

We can be sure, there is no improvement in DR, they would have mentioned it, even if there would be a developpment on the way. We can be sure, we will get no better sensor in the 5d4, and of course not in the 1dx successor, which is more about high iso and fastness.

Lets invest in some more expensive glass, and lets hope for the 5dsii

If you are attracted to the 300 2.8ii and plan to use it with converters most of the time, the 400 2.8 is to heavy and to expensive for you, then maybe you should try the 500 4.0. This one is not so much more expensive and will have better AF and better IQ at 500 than the 300 at 420 and 600. It will be a better 700mm with extender than the 300mm with 2x and a compromised 1000mm with no or poor AF

maybe for indoor sports, if 200mm is not enough, instead of buying a new 100-400 and a 135 you can stretch your Budget to get a 300 2.8 IS, for maybe 3000-3500 this should be available used.

Thats a fantastic lens, with great AF and better you crop a Little than have 2 stops more ISO and worse AF on a 5.6 zoom. The newer 300 2.8 ii would bave even better IQ and AF, and most important better IS, but for sports when you can use a tripod this is maybe not woth 2x the price

For me this really unique lens seems to be quite real now. If somebody would have faked the cpn page, he would have inserted the pic as well.

I am just curious on when and maybe together with which body it will be released?

Of course this is a specialist lens, with unique range and still quite fast. It should not be expected that it would be the fastest, smallest and cheapest lens, with IS and 58mm filter thread at the same time.

Lenstip has reviewed the Sigma 150-600 S.

Be aware that they received the lens they tested from Sigma.  To me, receiving a test lens from the lens manufacturer means that:
1.  The lens has probably already been tested by the manufacturer, and selected as being one that is the best possible. 
2.  You will never be able to get one as good as the one tested thru a store.

This is an urban myth and I'm sure that I've read a response to this somewhere that goes along the lines of "We (manufacturer) don't have the time to test 100 different lenses and pick the best one to send to a reviewer."

I would say it is pure marketing that the lenses are not carefully selected. if you consider what developpement and marketing of such a device costs, the cost to select the best one out of 100 costs nothing, and a good review is  miles more worth than any Marketing campain....... because the reader believes the test is independant.

Despite of this lenstip does the best and most scientific tests available for free (and i donated them a nice sum for reading the tests). Lens Rentals is a good addition, as they can test the sample variation

could it be that "the year of the lens" was just off by a year…that is they thought they would have all these lenses this year but just didn't get around to it…so instead 2015 will be the year of the lens?

every year so far was "the year of the lenses", and next year will be as well. Maybe we will see a new 18-55 EF-s, with updated design, and maybe cheaper to produce. The current one gives poor profit and is 2 years old now :)

To get a FOW this wide, the use of 8-15 fisheye at about 11mm on FF (with black corners) and correct with the hemi correction tool gives quite nice resultes. Compromise is, ist not exactlly rectangular projection and sharpness suffers at 180° FOW.

- it's 180° and not 120°
- it's 1000$ not 3000$
- the look is more natural than strongle recangular in my opinion.

For 3000$ one gets both (8-15 and 17TS) lenses, which gives all Fisheye Options, give UWA TS, 11mm rectangular with stitching for static subjects, and 180° FOW with correction in compromised quality.

All this together is more for me, than a 11-24 zoom for the same money.

To get compositions acceptable with lenses this wide, needs (at least for me) lot of time and patience, then using the tripod and maybe a lens change to take home all options is no problem and may get better results than a single shot with the zoom

The 17 TS has soft Corners fully shifted and lots of vignetting, thats true, but stitching gives a 40MP 11mm pic, which downscaled is really fine, and any other 11-12mm option has to prove her benefit first.

That would be nuts.

Imho this isn't the point, people buying all kinds of premium products can be called nuts.

But with the 5d3 release and the multiple delays for lenses and cameras, many Canon users have proven to be rather resistant against "jumping ship". Probably simply because they like their long-term brand, Canon service, Canon usability, Canon whatever and are as conservative as Canon themselves. If you have €25k lenses, another $1000 more or less for a camera that actually makes use of their potential resolution is a minor expense w/o running into compatibility issues with adapters.

That is not really the point. Existing users may be committed to a particular brand, but new users are not. By not competing effectively in the market Canon might think that their current user base will keep on buying their stuff, and that may be correct, but new users are going to buy the best tech available now, which is not Canon. And those users are going to show life long loyalty to whatever choices they make now as well. So, the damage done to Canon's market share might not show up tomorrow, but in a decade or so from now the effects of their short-sightedness is going to manifest itself.

My expierience is the oposite: i know 2 new Canon users, who bought a xxx Line with kit lens who told me, that Nikon would no be on a good Level to date, and a Canon cam would be better. New users often are uninformed and buy what their friend have or wat they see most frequent.

Therfore the market leader is in a Position which is quite comfortable and Canon uses this and is for sure the less innovative photo brand at the Moment, but the most profitable (wich means nothing else than that we pay to much)

To Friends who asked me for advice (for Safari/wildlife) with around 1000E Budget bought 24MP Nikon 5100 with 18-55 & 55-300 tele instead of of Canon xxx with 18MP and 18-55 & 55-250 tele, which gives much better Resolution on distant subjects

For them ist not a question if there is a 17mm TS, or a 8-15 fisheye zoom and which 600mm 4.0 is the better one

Means, this politics (of non inovation) is dangerous and the user opinion can Switch, like about Nokia, Long time they were told to have the most user friendly mobiles) even if there Situation is different in detail

ist really sure we will see 50MP FF cams, as we will see 50Mp APSC cams and as we will see 50MP phone cams

question is when and what is the benefit we get

Timing may be 6 month after Company leaders have decided, main benefit may be for the Producers of disk space

One limit is the resolution of our eyes. If you look at a 42'' Screen from 4 meter, between 720p and 1080p there is no visible difference.

To fully enjoy a 4k Screen i have to be 1.5m in front of a 55'' screen. That's not the normal living room configuration.

4k Needs a 80'' Screen at 3m viewing distance, and it is a aestetical question if y want to have a TV in your living room, which is so domitating optically, otherwise its not giving much benefit.

What i would realy love is a 8k Computer Display for stills, as i am sure soon even we Canon shooters will have at least 32MB resolution, but from the limitaion of our eyes, that must be a huge screen where we are standing and mooving in front of to see the details, wo won't overview such a screen (or print) in full resulution.

Maybe this lens is at the limit of what is possible with reasonable IQ and for acceptable price.

Maybe the question is, "have this lens without IS" or "not have it at all", just because there is no room for the IS unit or because of other restrictions.

The same may be true about 2.8 opening, it may be impossible, or unconvienient in weight, size or price...

So lets hope it is real, and has good optical performance

Lenses / Re: When will we see a replacement for the 100-400?
« on: September 10, 2014, 05:03:06 AM »
a new 100-400 will not canibalize the 200-400, thats a completely different Price league and the handling is completly different. Nobody will carry a 200-400 exept for a exactlty planned shooting, or for a special photo tour.

Nikkon seems to have a really good 80-400 lens, and the tamron 150-600 seems to be not bad as well, then there will be a new Sigma.

Maybe 100-400 Looks Little boring compared to the other offers. maybe Canon can strech the range to 450 5.6 with 82mm filter thread, or maybe they have to go for 6.3 opening, without extender compatibility then

Lens cap and shade are 2 pieces, where the cap is cliped on the shade. As generalle known this Connection tends to release unwanted, in the bag for example.

I blocked this release by thooth sticks, which works perfecty. I keep the lens closed, exept when effectivly in use, and remove the shade with the cap on.

If one does not want to see the lens anytime later, i would bond the two parts together
