Lenses / Re: 70-400/ f4.0-5.6 Zoom ... Canon, where are you?
« on: March 05, 2013, 07:30:56 AM »
The 200-400 is not available. And it is not affordable for 99% of non-Pro photogs. It is therefore NO alternative to a newly designed, excellent 100-400 II ... at a price not higher than the new Nikon 70-400.

If the Canon releases a better version, be ready to fork out at least as much... 2700.

Lenses / Re: Photozone spanks the 24-70 F4 USM L IS

By their own numbers, resolution is excellent at every aperture.  Just be sure to stop down for macro shots ... Standard operating procedure for any macro work.

Agree.  If the focus shift only happens in macro mode, then it's not too big of a concern to pick the f-stop first.  It would behave like a MP-E 65 where focus and magnification are linked.  It is a quirky lens though.

It'd make more sense closer to 1k as opposed to 1.5k.  I'm guessing the price will fall faster for this lens than other recent Canon releases since its initial pricing is so out of whack.

Lenses / Re: UV filters (any difference?)
« on: March 04, 2013, 08:11:17 AM »
Or you could do what I (and many other photographers) do and not put any filter on your lens.  I used to do it years ago until I was doing some night shots and the lights were reflecting off the inside of the filter causing a double image.  Maybe it was because I had a cheap filter, but I have since lived without them and my photographic life has been much happier.  Of course I am reasonably careful with my equipment, so if you are clumsy then by all means get one for protection.  But it is just my two cents worth that they are unnecessary.  Seems to me based on casual observation that snapshooters use them and serious photographers (especially pros) do not.  I suspect this is because the snapshooters are told by the salesperson at the camera shop that they have to have one.

And pros tend to insure their gear and/or use company/rented equipment.

EOS Bodies / Re: New DSLR at the End of March [CR2]

The Canon 40D had a 30 - 1/8000 sec shutter and a Flash X-Sync of 1/250 sec. Why would the NEW 70D have specs worse than a camera released in 2007 ???
Because the flash sync on the 6D is 1/180 and 5D3 is 1/200, so, no way the 70D would go beyond the 5dIII. I'm not sure I agree with the 1/4000th, but, it seems to be the way both Canon and Nikon are differentiating lines (D600/D800 and 5D3/6D). Wouldn't surprise me if the 70D had 1/4000th, leaving the 1/8000th for the 7dII

It might stay at 1/250.  APS-Cs have smaller sensors, so it is less demanding requirement for the shutter assembly.  The 60D and 7D have faster sync speeds than the 5D III already...

I'm hoping the 70D will be closer to the 7D II than the 4Ti.  The Ti line gets refreshed more often than the xxD and xD lines, so in 3 or 4 years, the Rebels can approach the 70D in specs in time for the 70D to be refreshed.

Lenses / Re: Canon EF 12-24 f/2.8L [CR1]
« on: March 01, 2013, 07:45:34 AM »
Given how the pros and Canon picked the 24-70 II over a competing 24-70 IS, I'm guessing that the same would happen with the 16-35, that it would be a lot sharper but not have IS.  Perhaps the IS version would be a 16-35 f/4.  That would mirror that all f/4 zooms would have IS, and that wide to normal f/2.8 zooms would not.

I'd prefer a sharper 16-35 II to a 16-35 IS that is comparable in IQ to what exists today.

Lenses / Re: 17-40mm advice please!
« on: March 01, 2013, 07:23:22 AM »
Consider getting a used 17-55, 15-85 or the Tamron 17-50.  Getting a good crop lens will give you more flexibility for when you choose to switch to full frame.  Upon deciding to move to full frame, sell the crop lens and get the FF camera with the kit lens.  The money you lose on the used transaction should be less than the difference of buying the 24-105 in a kit versus now separately.  If 17mm on a crop is wide enough for you, then 24mm on full frame will work too once you move full frame.

Lenses / Re: 24mm (not is) 2.8 prime or 17-40 l zoom?
« on: February 28, 2013, 04:09:52 PM »
According to TDP, the 24 prime wins in IQ.

http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=246&Camera=453&Sample=0&FLI=0&API=2&LensComp=100&CameraComp=453&SampleComp=0&FLIComp=2&APIComp=0

Most 17-40 users use it stopped down significantly for landscapes.  I would think that the 24 prime would be a more versatile lens if you want to use it for other uses too (i.e. environmental portraits).  You can always crop, but you can't go wider, so it really depends on how much you shoot near 17mm.

Lenses / Re: Keep or sell??
« on: February 28, 2013, 03:52:42 PM »
True, true... valid points. It's not like I need that little bit of money. Okay, I will keep it. Just out of my bag, and if I need it, it's up on the shelf.  :)

If you use something like LightRoom, take a look and see how many shots are taken at 50mm with your zoom and how many are taken with your 85 at f/1.8 or nearly wide open.  If you don't use the zoom much at 50mm or if you don't use the 85 much at large apertures, then sell your nifty fifty.  However, if you do use 50mm a lot and/or like the 85 wide open, then it might be that you just don't like the nifty fifty.  At that point, it might be worth considering upgrading at that focal length.

Just for the record, my bitching is more about wanting more functionality and redesign than cheaper price.  Just swapping optical for radio communication isn't a big game changer in my book and doesn't deserve my money.  I would like to see Canon do something truly great and shake things up using the big advantage they own... integrated camera functionality together with several models of great performance flashes with reliability and simplicity of use.  After all this time knowing what is out there in the aftermarket and designing the current new camera bodies and new flashes, this is all they came up with?  How unimaginative and incremental.  Yawn.

I don't think it can be done as easily as you think.  Different countries have different RF regulations and it may not be practical/possible to design for all of them in one unit.  Imagine having to a different 5D III model depending on where you live.

Perhaps, the next generation will bring the comm to wi-fi, which is pretty standardized.  Nikon just came out with the WR-1 system -- not a flash, but it still needs to be wired to the camera.  It looks like Canon will have a more elegant system for a bit longer.

EOS-M / Re: The Next EOS M? [CR1]
« on: February 28, 2013, 09:38:18 AM »
What I don't understand is when everyone here claims the full frame can't be done, why not use the same basic body of the 6D without the mirror/viewfinder?  No it would not be pocket-able - my sony nex 5n is not pocket-able, but it would reduce weight and size while still functioning just like mk111.

I wouldn't go to a job without two bodies in my camera bag I just would prefer if that second or third backup camera while having the exact same sensor characteristics of the main body could also be designed in it's own unique way. In this case as small as possible for those times when I want to go hiking, street scenes, video work, mounting in unusual places and don't want a full size dslr. (funny I use to strictly use a 4x5)

After using the sony nex I've come to one conclusion there are two size cameras one is point n shoot pocket-able and the second needs to go in a bag.

Here's my analogy (I'm not a golfer or a gopher) it seems Canon keeps making all these different cameras to be all to every use instead of making each camera body unique to help with specific problems.  A golfer doesn't carry around a bag full of 9 irons or (do I dare:-) a bag full of woods. Nor is their putter manufactured significantly inferior to his driving wood because it's a lesser tool.

Yes mirrorless cameras are here to stay however I disagree they need to be a whole new system, but I'm only a photographer(tool user) not an engineer.

If Canon were to make a mirrorless camera using the same EF lenses, then it wouldn't be much smaller because the mount size/design remains the same and it affects lens size.

If Canon were to make a mirrorless camera using a new mount, then wide to normal focal length lenses might get a bit smaller, but the large aperture telephoto lenses will be nearly the same size.  Anyone thinking that a 400 f/2.8 will be a lot smaller for a FF mirrorless camera than it currently is does not have reasonable expectations.  One of Canon's advantages is its large selection of lenses available.  Redesigning all the lenses for a new mount will take YEARS although an adapter can help lessen the transition pain.

I think Canon will eventually get to FF mirrorless bodies, but it will be a slow transition as technologies develop and production costs fall for the newer technologies (EVF at the same quality as the pentaprisms, etc.).  The other issue is that APS-Cs outsell FFs, so it's natural that Canon would address that larger segment with the EOS-M first.  I'd be tempted to get a 2nd generation EOS-M if it had improved AF for the wife and as a backup camera.  For lowlight and shallow DOF, I'd want to use fast primes anyway and those are not pocketable anyway...

1.  Wireless flash RF wouldn't affect battery life that much.  It doesn't seem to affect the 600 series flash's battery life much does it?  The flash only uses four AA batteries, no special high capacity batteries there.  Although now that I think about it, perhaps an integrated high capacity battery system on a full size flash might be a good thing with even faster recycle time and longer life.  Let me think... use the same LP-E6 battery in the flash too... hmm.  That might be something cool...  Eh, Nahhh.
2.  Cost is rarely a reason to not do things in photography.  Canon charges somewhere around 10 million percent profit margin already and everyone seems to pay it for whatever they choose to release lately.  Just look at the 1D-X, 1D-C or 1D 4K or even the 5D3 as examples.  Not to mention the newest lens prices lately running into the stratosphere.  Somehow I don't think integrating flash control into the camera will make much of a diff.

Or Canon would rather sell the same body worldwide and deal with the flash separately.  Different countries have different RF regulations.

And that's exactly what I want.  And what the overwhelming majority of the market wants.

I will definitely NOT waste time and money moving from my current Canon APS-C DSLR plus lens assortment (EF-S, EF) to a Canon APS-C mirrorless plus new lens assortment (EF-M) to finally a Canon FF mirrorless ILC Camera ("EF-really right") with still another lens assortment. No way!

1. I want to skip purchase of another DSLR
2. I want to skip purhcasing any further APS-C cameras
3. I want to move right on to a compact, hi-performance FF mirrorless ILC with
* excellent sensor
* fast contrast+in-sensor-plane Phase-AF
* hi-end EVF
* full ergonomic controls [i.e. 2 wheels! ] 
* at max. 1/3 of the cost of a Leica M system - so basically at the price of Sony RX-1 

The first company to offer this, will be my next camera system vendor. :-)

That's fine, but just be prepared to wait YEARS before that happens and even longer for a new set of lenses to take advantage of the new mount.  Until then, enjoy your current APS-C.

EOS Bodies / Re: Too early to sell 60D?
« on: February 21, 2013, 02:16:38 PM »
Sorry, but I really didn't mean for this to turn into a tech specs opinion post. Maybe I wasn't clear enough at the beginning, and if that is the case I do apologize.
The question I have is this; I have recently watched the new/second-hand price of my camera go down a few hundred dollars and I was wondering if anyone believes that with the release of the next in line, will my 60D drop in resale value again or would I be relatively safe to wait and sell when the new one comes out?

It'll probably drop in price.  Used 5D II prices took a tumble when the 6D came out.  At that point, you might as well consider using it as a spare body or convert to IR...

Any idea why ts lenses does not have integrated collars, so this could be done by simply attaching the lense to a stand, then shift the camera around?

If you're going to do much stitching, it's a much better idea to get a pano rig than a lens collar.  The rig will allow you to use all your lenses for panoramas.

16-35 f2.8L II

last vacation 90% i shot with this lens

i did take a 70-200 which i didnt use very much but carried everywhere

the other lens I took which i used alot was the 50mm f1.4

+1.  When I went to Disney, I mostly used the 17-55 f/2.8.  I lugged a friend's 70-200 II, which was primarily used for stage shows and parades.  If I were to go back, I'd consider leaving the 70-200 II home.  I would suggest getting a fast 35 prime.  It's nice for night time activities.  Large aperture matters more than IS in this context because most of those pictures will have people in them and someone is almost always moving.

EDIT:  Actually the 70-200 came in handy for animal kingdom too.  If you have a secure place to lock up gear (and insured), then it's feasible to only bring a lens or two at any outing in the parks.
