I'd like to know any extras I'll be needing or any I should just have for the hell of it. In particular the best lenses to get.
edesignuk said:I'm kinda in the same situation....I have the 350D + kit lens and nothing else. I've just found the Canon EF 50mm F1.8 II for £69, so that's not going to break the bank. But how about this "70-200 L"? Ideally something that wont break the bank either 😀 😱

efoto said:I'm pretty sure not....I've seen that series elsewhere on demo sites and sample galleries.
If you go to a camera shop and check out the 70-200 lineup (f4, f2.8, f2.8 IS) you can quickly see and feel the differences in size/weight, and someone can inform you of the performance aspects
The f2.8 model produces a nicer bokeh
BakedBeans said:any chance of telling me where? I highly doubt that you've seen it on a demo site or sample gallery (unless i posted it there of course 😉 ), if you have they are infringing my copyright.
yeah, you should check them out, the 2.8 and 2.8 Is are alot heavier and alot bulkier than the f2.8. the IS is a great lens but its thousands more expensive. The f4 is actually a little sharper than the other two - again, i doubt you could tell the difference.
no it doesnt. the shape and smoothness is exactly the same afaik. the background will be very slight more OOF though.
efoto said:Must be my mistake. I recall seeing images exactly like that (a series of them) for an eagle observatory out west here in the States....but I guess two different eagles can look similar.
I really have only seen sharper images from the f4 at f5.6 or higher, whereas the 2.8 (IS) can give sharp images at f4, so you do gain in aperture/sharpness by a nudge, if that matters to you.
"Another way to get a more diffusely blurred background is to use a lens with a long focal length such as the Canon EF 70-200mm f/2.8 L IS Lens used for the above Monster Buck picture. It will be much more difficult to blur a background with the Canon EF 16-35mm f/2.8 L Lens. All focal lengths yield the same depth of field when used at the same aperture setting and subject framing. But, the image compression a telephoto focal length provides magnifies the already blurred background. The result is a background that appears more diffusely blurred." taken from here halfway down, under the buck picture.
Perhaps you don't think a more diffused blur is useful, but many others do, and consider that to be more admirable bokeh.
They share focal lengths so for that argument they are tied, but I don't see how you can say that f4 produces the same bokeh as f2.8. I said they do share the same octagonal bladed aperture, so the quality is the same, but based on the DOF the 2.8 can produce a superior bokeh, perhaps more than you want, but I would prefer that option if the choice was given to me.

BakedBeans said:i was talking about bokeh, which is different from OOF back ground. you will get marginally more OOF from the 2.8 but not noticeable really.
i think you are getting a little mixed up, bokeh isnt the amount of DOF you can get or the more out of focus something is.
the bokeh is the same on both. you seem to be basing your argument on DOF and OOF areas
efoto said:Bokeh is the quality of the OOF areas, so yes I'm basing my argument on that. Perhaps I mis-worded in the beginning a few posts back, but I was attempting to state that quality of the bokeh is similar (based on an 8-bladed aperture instead of a 5 in many lenses) which allows a high quality (read: nicer looking and more consistent) bokeh.
I've read at a few places that DOF factors into bokeh, but if you're certain it doesn't then fine.
Regardless, I'm bowing out of this 'discussion' as I hate arguing over this s***, takes all the fun out of anything camera for me.
efoto said:The 2.8 isn't that much heavier than the 4 in my opinion, but the 2.8 IS adds in on without hold for sure.
For comparison, The OD on the 2.8 is larger than the 4 though, if that matters.
...but I would prefer that option if the choice was given to me.
-hh said:I just went and looked up the respective weights...
f/4 = 1.56lbs
f/2.8 = 2.8lbs (+1.2lbs)
f/2.8 IS = 3.2lbs without tripod collar (+0.4lbs)
The f/4 takes a 67mm filter, whereas the f/2.8 takes a 77mm filter.
Setting aside respective costs for polarizer filters and the like, I don't think that the difference between 67mm vs 77mm will make too much of a difference when it comes to camera stowage - - most of the "standard" lens bags I've seen/used over the years are set up for a 58mm diameter lens, so the f/4's 67mm will probably be too big, and you'll then have to move up to the "pro" lens bags whose diameters support a 77mm lens.
However, when shooting, it functionally is that extra +10mm of diameter in the glass that affords the faster glass. YMMV if you need it, but in my personal view (note: I just picked up the f/2.8 IS), it is when you get into lowlight conditions ... sunrise/sunset golden hour ... that you get frustrated at a system that's no faster than f/5.6 after you've put on a 1.4x teleextender and/or polarizer.
Everything is always going to be a trade-off, but I've found that having limited options is generally what drives one back to B&H to go buy something better...but its not really that its "better", but is a different trade-off. For example, the f/2.8 IS is a really fast system for low light conditions (especially after a high ISO is dialed in with a dSLR), but the trade-off is that it is an expensive and heavy lens. Sometimes, you'll want to stick with the 75-300mm f/4.5-5.6 IS because its much lighter (and less expensive too).

Awesome comparison, thanks for posting that [i]edesignuk[/i]. What aperture settings was your stock lens at when at 50mm?
er....good question, and I don't know. It was all on fully auto 😱efoto said:Awesome comparison, thanks for posting that edesignuk. What aperture settings was your stock lens at when at 50mm?

benpatient said:yes, they will use non-standard aperture jumps. It's fun to watch what my 50 f1.4 lens will do when I've got the shutter speed locked and the aperture set to "auto."
I get some apertures my old B&W photography professor would be fuming over....
1.6, 2.2, 3.2, 7.1, 20, etc.
