EOS Bodies / Re: Canon 18-45 f/3.5-5.6 Kit Lens for APS-C Mirrorless Patent
« on: February 20, 2012, 02:38:18 PM »

I'm not so sure what the outcome will be but I think Canon seems to have pulled all the stops in miniaturizing the lens design. Typical back focus for EF lenses are in the range of 40-70mm range. But this one apparently has a "0.5mm" back focus. Which means an extremely rear plane ! Typically, a lens with a very close rear plane can be made smaller to cover the same image circle.   

I wonder how this compares to other mirrorless systems or maybe even the Leica M system ?   Anyone has any clues what are the back focus of other mirrorless systems like the NEX  ?

18mm for the NEX. Here's a list of ALL lens mounts  http://en.wikipedia.org/wiki/Lens_mount

Gimme an EF compatible body and a pancake prime for taking on vacation and I'll be a happy happy man.

You'd buy a bulky/over-sized camera like a Pentax K-01 ?  http://pentaximaging.com/hybrid/K-01  A Canon CSC with an EF mount would have to be the size of a T3i without the Penta-mirror :(  :(

One odd thought occurred to me though – could the EF-S list be referring to full-frame equivalents? For example an EF-S lens that is the equivalent of a full frame 20-65mm would make some sense.


No-one in the real world talks about equivalents. When was the last time you heard a Hasselblad owner say that his 80mm lens was equivalent to a Full Frame 50mm ???   ;)  ;)

... but lots of people have fond memories of the eye controlled AF of the EOS-3.

And at the time enough people hated it that Canon killed "eye control."

EOS Bodies / Re: C300 Dealers & Price Announced in the USA

The big thing that the C300 has going for it is SIZE! It is a much smaller camera than either the Sony FS100 or F3. And SIZE MATTERS, if you are shooting on location, SMALLER IS BETTER.

A lot of Pixel Peepers have seen the Specs and proclaimed the C300 a POS. Many Union DPs have tested and seen the results on a big screen, and they don't have a problem with the C300. So who you gonna trust, Professtional Pixel Peepers :( or Professional DPs :)

I like Film Tools, good people who know what they are talking about. I buy camera, expendables, and grip equipment from them.

This solves the last problem  to migrating to the NEX 7 from Canon. Now I'll be able to use the EF 90mm f2.8 TS-E for product shots  :)  :)  A side benefit is I'll be able to use the EF 86mm f1.8 USM while waiting for a E-mount Zeiss 85mm.

Guess it also means that I'll keep my Canon Elan 7n film camera  :)

Come on Canon, it's past time for you to build a Pro Quality Third Generation camera. What are you waiting for  :(

You're comparing the weight of a mirrorless camera plus small image circle lens with a FF image circle lens?  Well, then...the S100 weighs less than 7 oz./200g including the battery and memory card, and has a 24mm-equivalent f/2 lens.  That comparison is only slightly less relevant, but if you want to save weight, there you go...

I prefer APS-C and DX cameras to FF. I don't sell 40x60 prints, I just shoot ads. If I need a really big print, than I'll use my 4x5 Toyo. My Only FF cameras are Full Frame Film cameras. I like small light weight cameras and I'm getting a Sony NEX 7 with a Zeiss 24mm f1.8 to test. If the NEX 7 works out, most of my Canon gear goes into storage.

BTW if Canon builds a Pro Quality Mirrorless with the requisite small/light lenses, I'll get one to test.

I'm not at all convinced this is true: I like primes—or, rather, I should say that I like the prime I have—but can't justify spending more than $500 on a prime. And I can't be the only person in this position; I'd like an equivalent of Nikon's $200 35mm / f 1.8. Which is what I hope Canon is going to offer.

Nikon's most expensive ($499.95 MSRP) f1.8 prime is the new AF-S NIKKOR 85mm f/1.8G. The AF-S NIKKOR
50mm f/1.8G is $219.95 MSRP. Nikon is upgrading their D lenses to AF-S G lenses and still keeping the prices reasonable, Canon could/should do the same.

BTW for thous not familiar with Nikon, AF-S = USM and G lenses don't have aperture rings (just like Canon lenses).

The 35L and 50L are much lighter (not much heavier than the 85/1.8), and 135L is only a little heavier than the Nikon. 85/1.4. All three of those L lenses focus very fast, too. The 85L is an outlier on both counts.  For an 85mm lens, an aperture of f/1.2 is 36% larger than an aperture of f/1.4.  I put up with the weight and slow AF of the 85L because it delivers great images.

Why would I want to carry the extra weight of the 85mm f1.2L, when I mainly shoot between f5.6 and f11 ??? My advertising clients are more concerned with their customers getting a good look at the product, than they are with creamy bouquet.

The combined weight of a Sony NEX 7 with a Zeiss 24mm f1.8 is less than a 22.9 oz./650g EF 24 f1.4L lens. For comparison the Nikon AF-S NIKKOR 24mm f/1.4G ED weighs 21.9 oz. (620g).

I like primes. Small, light and quick focusing primes. So this disqualifies the big, heavy L primes. A Canon 85mm f1.2 L weighs 1,025g and a Canon 85mm f1.8 weighs 425g. For comparison a Nikon AF-S NIKKOR 85mm f/1.4G weighs 660g.
 
IMHO, Canon should make a series of "85mm f1.8 quality" lens, not "consumer quality" lenses.

Primes work well for me because I usually work with only one lens. I can go for six month without talking the EF 85mm f1.8 off the camera.

RE Nikon vs. Canon AF.  Both manufacturers need a way to differentiate their lines, pro from consumer. Historically, with Canon that is AF - to get their best, you need the 1-series.  Nikon offers their pro-level AF in lower lines. OTOH, if you want a high MP sensor from Nikon, you pay for their most expensive pro body, whereas Canon offers a prosumer camera with the highest resolution they offer.

I prefer an APS-C sensor over a FF, but the 7D doesn't have the focus system and the metering I want/need. So I'm waiting to see what the D400 will be like. While I'm waiting I've bought a Sony NEX 5n, a great video camera but not much of a stills camera due to a lack fo a hot shoe. As soon a the Sony NEX 7 is available I'm buying one to test. I'm not a fanboy for any make of camera, I just buy what best fits my needs. And lately I'm not impressed with what Canon is offering. But a 7DmkII with Pro Focusing and Metering would impress me.

I keep hearing this and am wondering if Nikon really is better at focusing?

The Five Point auto focus on a Nikon F100 Film camera (1999-2006) is on par with my 40D. The 51 point auto focus on a D300, D700 and D3 is much better than the XXD and 5D/7D. The Nikon Matrix Metering is also better. The problem is that Canon has Consumer cameras (good focus), Prosumer cameras (better focus) and Pro cameras (best focus). Nikon only has Consumer (good focus) and Pro cameras (best focus), so the focus on a D300s is much better than a 7D. As mentioned by others, I use the center point only on my 40D.

Still waiting for a 22mm f1.8 EF-S lens.

Canon needs to make some more lenses of the quality and light weight of the EF 85mm f1.8.

BTW a Sony NEX 7 with the Zeiss 24mm f1,8 lens weighs less than a Canon 60D body. To some of us, high quality and light weight, is worth  extra money. So my question to Canon is, why are you driving shooters like me to Sony (weight) and Nikon (focusing) ???

I bought a Wimberley II gimbal head in 2006. Should last me the rest of my life. I use it with both still and video cameras. A high quality piece of equipment is worth a few bucks more.

BTW Calumet http://www.calumetphoto.com/eng/product/calumet_large_lens_gimbal_head/ck7075 and Induro also make Wimberley copies.
