Something is wrong with the curves, a lens always loses sharpness above f/8.

However, lenses with decentered elements do exhibit strange curves. That's one quick way to spot a lens that needs adjustment.

This are some typical curves. They doesn't go above f/11, but resolution continues to drop off slowly as aperture increases due to diffraction.

Hello all,

I am looking for an upgrade to fullframe and will probably buy an 5d mkIII in the next couple of month.

Also I am considering in a new tele lens which will mostly be used for portrait, sone zoo animals and "kids action" photography. In total I am doing this only as hobby for myself and my family and not as a job.

Now my big point is which lens should I choose?
canon 70-200 2.8 IS II USM
or the new tamron 70-200 2.8

Tamron was brought in to my mind by a good friend of myself - but up to now I couldn´t make any decision.

Any suggestion any support on this - at least for me difficult decision? I would like to get a comparison of the iq of both lenses but couldn´t find any reliable review about the tamron. I know the canon is a superb lens with an high price tag also

Thanks for any help.

Hi guys! I like taking tight portraits with a very nice bokeh, and therefore I'm planning to buy a Zeiss 100 f2 Makro lens due to its remarkable optical quality on full frame DSLRs. We've heard that Zeiss is going to update lots of its lenses for high-megapixel cameras, and we've already seen a new Zeiss 55 f1.4. I'm wondering if any of you guys heard about any rumors of the updated version of a Zeiss 100 f2 Makro lens? How much improvements in optical quality (and price tag too, I guess) do you expect a new line of Zeiss lenses? Any suggestions will be much appreciated! Thank you

April 1 is a bad time to ask

Well, I guess you're right. But I'd really appreciate only serious responses.

I heard that Apple and Canon are collaborating on a DSLR which has iPad functionality on the touchscreen interface. I'ts supposed to be called the "iCanPad".

actually.... why not?

And Nikon and Microsoft are working on a Window 8 pad which takes the original series of Nikon lens - you know the ones with the aperature rink. Only problem is that tablet needs to be rebooted (takes 2 minutes) and the lens must be removed at the just the correct time - otherwise the reboot does not work.

Thank for you who helped, got it replaced, new one works as I would expect a lens of this caliber to work.

Hey Mt Spokane,

Thank you for your rapid response, I've always enjoyed reading what you have to say on the forums. I went ahead and downloaded the images through EOS Utility, simply because I need to get todays shoot out mucho pronto. I think I'll invest in a card reader. My computer has one built in, but the CF slot is the only one that has NEVER worked (go figure). Ultimately, I'm just going to go through with a card reader.

Thank you again,
-Tabor

By the way, are you in Washington?

Yes, I live on the flanks of Mount Spokane, 20 miles North of Spokane, Washington.

Can anyone please advise me if it is possible to change the Quick Control Screen colors. My default is black screen with dark and some lighter blue, and I thought that I have seen some with lighter colors. Not a big deal but just wanted to know. Thanks in advance.

The detail ( to me ) is incredible , The poor 7D is on it's way to collecting dust.

Excellent shot! Another confirmation that it is all about light (and the photographer). BTW, you can see the noise but without the EXIF, it is hard to make judgments.

You can purchase the full set of eight ink tanks (Canon #8) from Amazon for about $85 US as a boxed set.

I have both the 24 and the 17 that i use for landscape. The 24 is definitely slightly sharper if you are a pixel peeper. The biggest drawback to the 17 for me is that I have to carry a set of larger filters that don't really fit well in my bag or vest. I'm still handholding them for the 17 now and am debating on getting the filter holder from fotodiox. Truth be told, I've actually found myself leaving the 17 at home more often in favor of the 24 because of the filter issue. I've been using a RRS pano rig and shift/rise/fall to make multiple exposures for stitching. The 17mm really works best for me when I'm on the coast and there is too much movement within the frame for stitching in post.

My sources tell me that on Monday we will see lots of incredible announcements - Canon buying Hassy or will it be Leice. Perhaps a MF Canon to fit Leica glass. Nikon licensing their 14-24 to Canon.

What are you expecting on Monday, the first of April?

Yeah right! :

noisejammer · Mar 31, 2013

I made a mount to suit my TS-E 17, all my Lee Filters (4" x 6") work with it EXCEPT the polariser which vignettes heavily. This is not really a limitation - a polariser will cause the sky to take on strange colourings in such a wide lens.

These filters are all usable on a 24/1.4 II provided you have the correct mounting ring.

I took the plunge, and the advantage of the Australian dollar and went with the Zeiss 95mm filter. Not cheap, but then, neither is the Zeiss lens. B&W did get something out of me however. In advance of buying a Canon 24 f1.4 lens, I added the B&W 77mm UV filter to the order

noisejammer · Mar 31, 2013

I own the ZE 21/2.8, 25/2 and 28/2.

Make no error, (in spite of a comment to the contrary) the image quality of the 25/2 is obviously better than either of the others. It is a great lens with one caveat - I have not been able to extract the 3D look that pops from the 35/2. It may be that I need to play with this lens lot more.

You might give serious consideration to purchasing the ZF.2 model - it offers freedom to choose the body you prefer and glass like this is certainly good enough for high resolution sensors.

You used to be able to get the tubes new off eBay for very little money. They are a bit of a fiddle to change but very doeable with a set of small screwdrivers. If you don't want to do it then any camera repair shop could do it for you too. Much better option than giving up on the flash.

Yup paid full price when it came out so may be worth saving. Not too good at do-it-yourself so I will have to take it to the local store and start there.

CharlieB · Mar 30, 2013

The real thing to consider is - do you go with FD or EOS film.

In the FD world, there are lots of good cameras for just a little money - but - you'll need the glass too.

In the EOS world... you're limited a bit. I've had two EOS5's (A2e's), and still have one, just to have it. They're ok, but compared to todays digital, are a very clunky and odd design.

The EOS3 is also very good... amazingly so. If you can find one in good shape, its not a bad "film camera" to have.

These days, all my film work is with Leica. I just love it. Wish the M9 was more affordable, and had a bit better sensor (but I can live with the sensor).

Cheers

Last year I took a virtually new 24-70L to Canon in Irvine, California, to be electronically recalibrated because it was back-focusing. I was assured by Canon that the lens would not be dismantled. However, when I returned to pickup the lens, I was told that three collars were replaced (on a brand news lens, go figure). I was upset because I had specifically instructed the service center to not open the lens because it was new and I was going to return it if it could not be electronically recalibrated. Also, after the "service" the barrel was slightly loose and the focusing inconsistent, so I called and complained to Canon corporate in NY. A really nice lady at Canon confirmed that my request was not honored and authorized a free replacement lens, which I received and was very pleased with because the AF is accurate on the new lens.

Most review sites buy their equipment or borrow it through normal market chanels. This is one of the reason why reviews tend to be so uneven and contradictory, copies of certain Canon lenses can have as much as 30% variation in performance. That's thirty percent.

That might be as well 30% variation of the accuracy of the tests, not the lenses.

here is my thought:

70-300l for more reach: imo, i would not choose this one... for more reach, i would wait to get 7d mark ii or 70d so that i would add another body to my list and it will be obviously more reach than what you have planned when pairing with 70-200mm. someone here might claim that 5d mark iii is better at high ISO... sure, but keep in mind that lens is f/4-5.6.... at most two stops and think about it, you can shoot at f/2.8 with focal length of 320mm instead of f/5.6 at 300mm

This applies only if you're making big prints (larger than 16x24"), submitting for publication, or have some other need for high MP, the cropped 5DIII image will have equivalent IQ to the APS-C image (and better IQ at higher ISO). The 'reach' of APS-C is often an illusion.

Plus, the OP's talking about lightening his load - does carrying two bodies make sense?

The part about the primes that kills me is to keep two people in focus I end up having to stop it down so wondering what other benefits the primes will have besides subject isolation options and compositional thinking vs zoom.

Click to expand...

With the MkII zooms that you have, when stopped down to f/2.8 or narrower, the primes' advantages are negated, except sometimes size/weight (e.g., 135L vs. 70-200 II).

You can't bounce this so I'd avoid it; direct flash is horrible.

Might want to check your facts before making an assertion like that...

I was thinking the same thing about the 270 while weak it is a good travel flash.

The rest of the story:

After a drink or two, Nikon and Canon head to their homes in the suburbs. They have a good laugh on the train ride home as they think about the guys sitting in the corner, still living in their mom's basements without much hope of ever getting a date, much less finding a wife.

Then their thoughts turn to Leica. Some people are jealous of him, but really, to them he's just an object of pity any more. He was once married to the most beautiful and desirable woman on the planet, a real Looker, she was more exciting than Life itself, no one could Match her and she never uttered a Stern word. But, alas, she died decades ago and poor Leica has never been the same. Now he has to content himself with the company of those with more money than brains, movie stars and others. Sometimes they don't even know enough to take his lens cap off.

Nikon and Canon smile. They know they've put on a few pounds and when they look in the mirror in the morning they are surprised at how much hair they have lost and how many wrinkles they have gained. They once dreamed of a life as jet-setters and even had a taste of it, but they were born too late. Still, as they walk through the doors of their safe, suburban homes, they think of their loving wives and happy children and realize that even if this isn't the life they once imagined, it's a pretty good one just the same.

But...that Fuji kid, he is a hard one to figure out. His family made their fortune in an industry that is now dead, yet they managed to survive and prosper while others hit the skids. Nikon and Canon aren't quite sure if he comes calling on their daughters, should they welcome him in or should they stand at the door with a shotgun?

It would be interesting if Canon (or Nikon) would welcome Fuji into their household. Fresh blood is always good for the gene pool.
