Follow-up question: Who the hell is renting a Rebel?!

It does not matter. There are plenty of people buying rebels. I seriously doubt that Canon is only shipping flawed sensors to camera rental businesses.

The old 90 got to 1/2 life size.

Click to expand...

The 90mm TS-E goes 1/3 not 1/2, so it cannot be really considered as a true macro lens. It goes x0.43 with the EF12 tube and x0.6 with the EF25 tube. However I end up using it more than the my 100L for close-up.

Problem with tilt on TS-E lenses, it's a front tilt only. Front tilt brings you quickly out of the image circle, rear tilt changes the perspective a bit, but allows tilting with a smaller image circle.

Someone mentioned the Contax tilt/shift bellows, Nikon did that too with the PB-4 bellows back in the 70s/80s.

Personally I would have preferred a replacement of the 45mm TS-E first, but I am nevertheless curious to see what Canon will bring.

The site doesn't appear to go back to late 1967 when I got my first Canon SLR, an FT QL with the 50mm 1.8.
I was 13 (or just about).

Sony's trend is up, Canon's trend is down.

True. Canon's downward trend means they posted only a ¥48B income. Sony's upward trend means they posted only a ¥128B loss. Wow, that's sure good news for Sony and bad news for Canon. I highly recommend you invest all your liquid assets in Sony stock, based on that incredible upward trend you mention.

Sounds a lot like the sapphire (synthetic aluminum oxide crystal) lens on my iPhone. There's a filter company ( in Korea?) that is launching UV and CPL filters made from it, too.

Click to expand...

This is true, but sapphire is significantly harder (Mohs rating of 9 vs 7.5 to 8 for Spinel), so it's unlikely they will ever grind it down into an aspherical lens shape (flat screens covers and filters are much easier to make). Also, Spinel is slightly more transmissive optically (splitting hairs, but whatever).

On the flip side, sapphire has significantly higher fracture toughness than Spinel (up to 4 MPa m^(1/2) vs about 1.5 MPa m^(1/2) http://www.ceramics.nist.gov/srd/summary/ftgsaph.htm, and http://www.ceramics.nist.gov/srd/summary/ftgmgal.htm), but both are much harder than glass that is about 0.8 MPa m^(1/2).

In any case, I'd welcome either material if Canon found a way to manufacture lenses out of them, but I'm more hopeful for Spinel because there are already optical products made out of it: http://www.surmet.com/technology/spinel/

Also, expecting FF quality (OP is comparing to a 5DIII), may still be high expectations in 2015. After all, 7DII costs half of 5DIII release price--and includes new features.

Very keen to se new firmware.

Dont ever believe this. At all.

Man, i wish you guys can see what i get out of my old t2i and 70-200. Even my new wonderful 5d3 is only marginally better at iso100. And it took me aout 6 months of fiddling and repair send to get my 6d to act proper.

From my tests, 70d has impressive iq- IF the damn focus works. Mine was so busted that i almost gave the canon rep the yell of thier life. 4 days, no images in focus. but i kept cool and sent it back. That same body wa the one that was listed on CR as a refurb deal. I feel bad for whomever bought it.

Anyways, look what nikon is doing with even thier low end bodies. 3300 and 7200 iq and Dr runs circles around canon (non 5d/6d/1dx) offerings. I wont go out and trade my canon gear, but my head is also not in the sand.

So in a nutshell, making excuses for manufacturers is a fools game.

Detail and sharpness is always a combination of lens + sensor. Since I would purchase this body as a dedicated macro body for high magnifications (2 - 50x) only, I test with the optics that will be used with this sensor.

At higher magnifications, diffraction becomes more an issue and often the limited factor in sharpness. Therefore, a studio setup with some fancy stuff (e.g. pencils and colored fabrics) with a 50 mm at f/8 does not say anything about what will happen when you compare with a 10x microscope objective instead.

I just realized that my daughter is avoiding me coming to her graduation day after. She was telling her mother "He will bring his big camera and everyone will look at me." Ouch.

Plan A: Tell her that this is one of the most important moments in your life and you want to capture with your best gear. Plan B: Bring a less conspicuous camera and behave like a street photographer and Plan C: hire a pro-photographer and enjoy the ceremony.

Plan C+ (D?): Bring your best gear, shoot the whole ceremony, then sell the photos and give her the proceeds.

Brilliant. I wish you would have told earlier.....

jrista said:

Absolutely. With a lens like that, you will want to get a midrange mount with the right capacity, and you will want to mount the lens properly on the right kind of dovetail with the right kind of mounting equipment. I am actually working on some articles for my site that will cover exactly how, so keep an eye at the following for more information:

give them too friday if not saturday
if no new firmware then it was BOGUS story or canon said that too an annoying costumer who send there 7d2 in but still had problem bka (a shut them up comment)

Sold!
I hope the new owner realizes that it looks like a rocket launcher, and that he ought to introduce it to local officials before going on a shoot.

Thanks

@Eldar: Does your RX100 III start to make a noise like a electric razor until you take the battery out and let it calm down a bit? Mine did that every once in a while. I do not know what was the problem. Like the focusing motor trying to complete an impossible task.

Click to expand...

No, can't say I have noticed that.

I've owned that lens once and sold it. If it was an f/2 i would keep it (ok to be slightly larger)
It doesn't meet requirement 1-4

Anyways, i checked out DXOmark and the Sony 35 f/1.8 resolves 11 perceivable pixels out of 24 on the a6000.
However, the Samsung 30mm f/2 resolves 14mp out of the older nx20's 20mp sensor which is very high. I'm guessing it should resolve around 18-20mp once tested on the NX1's/NX500's 28mp sensor (no AA filter).

Another crazy gem of a lens is the Samsung 10mm Fisheye. I's 1/3 the volume and less than 1/3 the weight (71g) of a Rokinon 8mm fisheye!!

I think i'm leaning towards the Samsung. It's crazy how a whole system decision can be made because of 1 lens (the 30mm)

And you've checked AFMA?

Thanks for sharing this information. It'll help some here to take decisions

Ah! A 200-400 . I'm sure this would help my photo projects too.
I know a lucky man who has one. He uses it to shoot Jet Fighters going down valleys in Switzerland (this seems to be a popular thing there - looks brilliant - it must be difficult to do - panning at that speed).
He gets great results.
He thinks it's a super lens. Drooool !

I always suspected that they had to purchase a minimum number of D4 sensors, and with sales slowing, they were looking for a way to use them without hurting D4 sales. I don't think it worked.

We are going to see more of this throwing products out to see what sticks. Canon is starting to do it as well.

It would be a simple, and not very costly retool, to fix the ergo problems on the DF which would make it a fairly fine body to use after that. AFAI could infer from the rep's' responses the present DF's a serious flop.
OTOH, the 1v3 is getting a fair bit of attention and so will the new 1J5 because of their very high fps abilities. But it's a very pricely little ML system, even if it goes like a cheetah.

Issue solved. Returned it and got a new one. No problems now whatsoever.

More of this kind of post, please! Hilarious!

It would be a damn crying shame if they did go under.
IME, there is no better flash to be had.
My No.1 go to "mecablitz Metz 30BCT4" is 39years old, never missed a beat. Still puts perfect, even, 52K, out to 60metres (200feet).

I tried stacking my 1.4XII and 2XII on my 600mmL and 1D MK III for a 21XX equivalent focal length. The result was poor, and it still wasn't long enough.

This one is from yesterday with 1200mm equiv using my SX50. Its viewable, but not pretty.

That nest is in the top of a very high power transmission line tower. I think thenest must be 5 ft deep or more. It took them 3 years to build.

* you didn't test phase af tracking, just video af - I take it you know the difference. You're just shooting stationary birds and say the focus system is "very good" (sic!). And you didn't have a look how much you can customize phase af tracking in the firmware. This is one potential big difference to the 70d.

Click to expand...

760d should have the same af as 7d which has been praised. so the potential differences could, indeed, be in software.

EVen if you get a good copy of the 14mm f/2.8 Rokinon/Samyang, it still has a generous amount of distortion that you have to correct if you have something with a straight horizontal line in your picture. I found a lens profile for the LR which is doing an OK job though it is for the 5DII.
