people were definately using flash in that video, hence why i say shoot burst and have a high recycle flash so you will at lease catch a break in the other flashes if your flashes coincide it will blow out the shot. I dont think AI servo will keep lock if you try zoom but using back button focus its easy to reaquire lock after zooming just remember ai servo needs about a second to fix its lock on. with back button focus you just hold that puppy down and shoot so you dont have to worry about balancing the shutter button half way thats why its there as an option

i find its useable on the 24-105 unless the ambient is very dark but 95% of the time its fine
strangely the 600f4.5 doesnt seem too dark at all

Sorry but no, EF-S lenses are designed for APS-C sensors and can not be used for larger sensors.  EF-S lenses extend further into the body therefore the larger mirror on an APS-H or FF would hit the back of the lens.  EF-S lenses also produce a smaller image circle designed to cover an APS-C sensor only.

Perhaps its not clear in what I wrote. Let me elaborate.

In-camera crop on an APS-H sensor to use an APS-C lens isn't too far of a stretch isn't it ? The mirror of the 1.3crop isn't that big compared really and with some tweaks, it may fit an EF-S lens.

There was a story / article of a guy  who did something of the sort with his 1D and mounted an EF-S lens, albeit with some minor modifications to his lens only. The height difference between an APS-C and APS-H is less than 5mm.

So, it might be possible to tweak the mirror in an APS-H camera to have sufficient clearance for an EF-S lens' rear protrusion.

Thus an APS-H camera with an APS-C crop mode by allowing it to accept EF-S lenses. Especially if the AF module was designed for APS-C in the first place.  Possible ??  ;D
I think its physically possible to do and then why not consider making it mirrorless! no problems with mirrors hitting lenses anymore.

also not sure how many here have used nikons but say you put a DX18-200 on a full frame FX film body you only get very severe corner vignetting not unlike what the tamron 18-270 delivers that people seem to put up with. on the FX digitals the electonics crop it to 1.5 for you so you dont get that.
Even using the APS-C EF-S lenses on the APS-H sensor would only result in some corner darkening anyway then let the user crop as desired

I think an APS-H with APS-C in camera crop that can use EF and EF-S lenses would be cool especially if you get boosted frame rate with the APS-C mode too. If that was canons entry to the mirrorless segment it would set the bar pretty high for the sonys and panasonics to chase and the nikon v1 and j1 would be outdated instantly

If you compare the 5D and the 7D, it is obvious how much detail is lost between the sensors, especially in higher ISO. That is my biggest complaint with the 7D, I run into that when I shoot no flash ceremonies and receptions that are low light. I use bounce flash almost every reception, but I would love to limit flash use overall.
I say wait, at least until the offical announcement then decide.

and don't limit your flash master it instead :)

i put this in the other thread too

Here you go

see if you can stretch another $500

and go 60D with 17-55 f2.8 IS and the 70-200 f2.8 non IS

http://www.ebay.com.au/itm/U1821-Canon-60D-17-55mm-f2-8-77mm-CPL-16GB-Bat-Gft-Wty-/380410110627?pt=UK_CamerasPhoto_DigitalCameras_DigitalCameras_JN&hash=item589235a2a3

you will get more benefit from the f2.8 non IS for action sport than the f4 IS since you wil be chasing high shutter speeds even with the IS version it is recomended to turn IS off for this type of shooting anyway.
I've bought from these guys off ebay before they are good, others i have used are digital rev, hk buy n sell, dzone2, ozdigital online. most of the hong kong sellers are pretty good to be honest. i've sent lenses back even had digitla rev intercept an order that had been shipped and have it returned to them because i had ordered the wrong lens nikon 50mm D version instead of the G then got them to send me the correct one. No charge even though it was my stuff up

I'm in the market for a DSLR and two lenses, willing to spend about $2500.  I'm thinking EOS 60D and canon ef-s 15-85 and 70-200 f/4L IS USM.  Any thoughts?  I'm mainly shooting family photos/outdoor activities/youth sports and travel shots.

if your filter gets stuck just sit under aircon for a bit to let t contract then you can get it off, its usually only a potential issue if you are in hot weather that it can bind up

Am I to expect the same 61pt AF system that's in the 1D X?
the rumour says same but simplified which might be a good thing

« on: February 14, 2012, 08:26:18 PM »
One of the reasons I think you don't see the 24-70 with IS is the short range of the lens, as well since it is capable at F/2.8 and looks like it does not have to be stopped down to be affective

I don't understand why people seem to think that f2.8 is *always* better than f4 and above - in many situations, the dof of f2.8 larger apertures is just too thin, and the bokeh of f4 is ok too if there's no irritating object directly behind the dof pane. This is definitely true for my macro lens: 2.8 is just ridiculous if your object is not a flat piece of paper.

Of course I want a medium tele lens with IS - then I can shoot static objects with large dof at iso 100 and no noise! The only reason the 24-70 has no IS seem to be weight considerations - which I can understand given the weight of a 70-200/2.8is2.

Does IS make a noticeable difference shooting hand held at above 1/60th at a distance of under 20 feet with a focal length of under 70?

IS gives more good shots, nothing more - or said the other way round: If you have enough time you can just take a picture burst, one of them usually will be sharp. With a lens w/o IS you can get crystal sharp images, because your hands move from one point and back - at the peak of this sine curve your hand is steady like a tripod.  If the shot is steady, only the lens sharpness matters (if you've got a good copy, that is).
f2.8 and faster lenses focus faster and better due to the AF sensor sensetivity even when stopped down

EOS Bodies / Re: Anyone else want a cropped sensor?
« on: February 14, 2012, 08:02:03 PM »
Yes, i want a cropped sensor... a 7D mk2 that use a APS-H sensor ( cropped :) ) and the ability to use EF-s lenses.
well, I'm afraid that's not possible. EF-S lenses are only compatible with APS-C. You need FF lenses for APS-H... ::)

Indeed. Even if they did work, there would be serious vignetting. The short back focus might get in the mirror's way, anyway.

Nikon have the capability to have DX lens on FX bodies. Anything is possible.
I was wondering if this was actually physically possible.. waiting for neuro to chime in i'm sure he will know if an ef-s lens has enough coverage to use an APS-H sensor with a different mirror setup. of course they might do away with the mirror issue altogether ;)

Obviously, the 5D was purposefully limited in some areas just to keep from cutting too many 1Ds sales.  AF was one of them.  I mean -2 to +2 on the exposure compensation instead or 3?  That's software for $@#$%#$ sake.

On the other hand, it is/was one hell of a camera for the money.

.... it has the ability to changes the settings via the screen whereas the the 1Ds3 doesn't

The 1Ds3 also has Series 1 features such as 7 shots bracketed, twin cards etc etc

The 5DII focusses better at very low light (on the centre AF point) than the 1Ds3
how do you think it is compared to the 1D4?

« on: February 14, 2012, 07:23:51 PM »
those lenses will be pretty good for animals during the day, lots of birds on safari too, if you wanted a fast prime I would look at the sigma 85mm f1.4
if you get the FF the 24-105 will still give you excellent landscape shots if you stay crop only you might want something wider than the 24mm

nice low ceiling to bounce flash, the models look good. should be able to get some decent shots for a portfolio
just make a trip of it with your wife
with all the competition you are going to need the 1D mk2 fast burst rate
get yourself a yongnuo external battery pack to help boost your flash cycle time so it can keep up
do you have 2 flashes you may overheat one and need to swap it over to let it cool down.
go for it

Several things here

1. Canon are not stupid they have been around for a long time and are the market leader - they want it to stay that way

2. they are clearly addressing all the concerns of the FF crowd me included :) maybe not as quickly as everyone would like but I think this next round of products are going to pretty awesome.

3. They most definately have noticed the EVIL / mirrorless competitors savaging the bottom end of the DSLR market. I fully expect they will respond with something here that knocks the competition out of the park. Everyone in the mirrorless arena talk up APS-C sensors as being huge, cannon are already all over the APS-H tech, might we see the rebirth of APS-H in this format? The thought of an APS-H mirrorless at a decent price, with and EF adaptor?

4. I seriously doubt canon are going to just drop the APS-C crowd or let it die I think they will come out with a stunning high end APS-C. The build of the current 7D is great if they use the same body and beef up everything else and call it a 70D does it really matter? they do need to rationalise the APS-C line especially with the mirrorless compacts eating into that arena i mean 7D, 60D, 600D and 1100D with a price gap of what $700 seperating all of them? somethings gotta give here.

anyway thats just my thoughts on the subject
Canon bring it on!

Tamron made a 28-105/2.8 some time ago.
http://www.fredmiranda.com/reviews/showproduct.php?product=242

The lens had a reputation for being very soft wide open.

But - it goes to show that an f/2.8 zoom with this range is not impossible.  Perhaps with modern lens design and the latest in high-refractive-index glass, one could design something that's useable.

yeah by all accounts it was softer than a marshmallow on a bonfire :(
