coated less reflections and flare.... the strength is how many stops of light it will remove....

Haha, I know. Well, I'm trying to have my cake and eat it too.
I tell ya I did my best to forewarn her how expensive camera gear is and being with a photographer can take it's toll... I dont think she fully understood until well after the nuptials ahaha. Oh well it's worth it in the end, or at least when i'm not trying to buy more gear haha.
AnthonyWithNoH said:Seems to me a large percent of the rumors (even the official ones) are often off. These new 5D ones that are arising seem very plausible though... thoughts? Have you all been disappointed often with rumors here?
moreorless said:Added to that are large appature AF zooms ever going to be compact enough to balance a mirrorless system? without them your dealing with a very different market, one that only currently exists in the very small/prenium M9.
Not saying such a market doesnt potentially exist but its clearly much more risky than mirrorless ASPC
Tijn said:I've seen that option. Was looking for the opposite, something to stop the AF while in AI servo mode to change the framing without losing focus. I did find that...neuroanatomist said:That's why many people (me included) use back-button AF, where a shutter half-press activates metering only, and you press teh AF-ON button to AF.
I guess that if you use back-button AF instead, you can just stop it servo-focussing by releasing the button? Personally I've not tried it yet, but I did find that back button a bit fiddly to find (for AF stop) for something as important as focussing.
And you're correct, it might have been the 85L. But it was either that or the 135L, it was an 'odd number'. But it was an f/2 prime for sure. The person who had it didn't know much about it either (she had just got her new body for a week and borrowed the lens from a friend or something).
Thanks for yet another explanation.
Only if the field of view is identical. If taken from the same spot with the same setup (and therefore a different field of view), then the full frame actually has greater DoF.Nostrada said:moreorless said:LetTheRightLensIn said:dilbert said:I'm hoping for 20-somethinig MP ... the Nikon camp is currently in a dither because Nikon is saying that need to use it with a tripod nearly all the time! lolz
And what of the 7D? 60d? 50d? Nobody ever uses them hand-held? Hah, they all have higher photosite density than the D800!
Shutter speeds are going to be lower on a D800 at similar ISO's and similar DOF's to crop bodies though arent they?
One other thing: the DOF on a crop body, even at the same f-stop, will be greater than on a FF body, so I would assume this helps minimise the effects of high photosite density and make the image appear sharper, simply because more of it is in focus.
macfly said:Well since I'll be getting one in the first batch I'll do some direct side by side comparisons with my 1Ds Mklll and can post them here if you're interested, but of course the glass will be a variable too, not just the sensor. Anyhow I need to do it to for myself to know what I'm dealing with, so happy to share.
Chuck Alaimo said:I am genuinely happy with my 7d, but have gotten to the point where I am just sick of having to have the 10-22 to cover the wide end, when my 24-70 would be wide enough for most of the work that I'm doing. In fact, I like like my 7d enough that if i can swing it financially, I plan to keep the 7d for the rare occurance i need the reach a 1.6 crop can provide, and for lower paying gigs at places i wouldn't feel comfortable bringing my FF into.
Chuck Alaimo said:The only one that i can see the worth in desiring on an FF body is the 17-55. Even the 10-22, which i own, and is a fun lens, I wouldn't want that on a FF body. The IQ just isn't good enough.
Chuck Alaimo said:So, to a large extent, I feel that the ef/ef-s argument is really one of those is the cup half full or half empty arguments. Yeah, you could see it as a big ol road block. Or, you could see it the other way, as an opportunity to invest in better glass...

Elves know when they're onto a good thing. And it also seems to be the current camera of choice for smart professionals. Best combination of features, image quality and price.
its definately got bang for buck covered not sure i would be brave enough to shoot a wedding with it though...
NotABunny said:The reason why the entire image from 5D2 looks cleaner is because it has a sensor that is 1.6 * 1.6 (= the crop factor) times larger than that of 7D. This is 2.56 times, meaning that it's log2( 2.56 ) = 1.35 stops cleaner. This is the expected difference.
This happens because images have a physical size, and this size is the size of the sensor. The larger sensor captures more light for the same photo. This can't be seen practically because the images are always scaled to display / paper size (= the same physical size), but with different scales. The images made by a sensor as large as a display don't need to be scaled at all (compared to a small FF sensor) and would therefore show stupefyingly low noise levels (for the entire photo). Unfortunately, the lens needs to be proportional in diameter.
unfocused said:Interesting post on that "other brand" rumors site. They have a price list that shows the new Nikon D800 cost to dealers at $2,699.96 U.S. and the MSRP at $2,999.95.
I would expect the 5DIII to sell for essentially the same price as the D800. If Canon offers similar pricing margins for their dealers, I wouldn't expect to see much of a discount.
JTPAIN said:Sorry to post a question within another post - i hope the OP doesn't mind?
Wouldn't a fairer comparison be
17-40L vs. 17-55 IS
Between these two - which would 'win'?
