Software & Accessories / Re: corrupt file name provided by my 7D
« on: July 01, 2011, 09:45:22 AM »
when mine, it just created a bad file... camera couldn't read it, computer couldn't open it... With my situation it was the card screwing up.  Incorrect or odd file prefixes i would concur with neuro

I had that happen a few times on my 7d.... i was able to trace it to a specific memory card i got from best buy.  I dont use that card no more and knock on wood I haven't encountered that since.

That way he's not being forced into buying additional lenses JUST BECAUSE he is upgrading bodies, unless he wants to.

That assumes s/he will sell the 7D upon going FF.  I didn't...and I still have (and use) my EF-S 17-55mm f/2.8 IS.

True enough...

"First of all, i love lanscape wide angle pictures," and a 24mm lens on a 7D is not wide angle.

Well 24mm is wide angle if you walk back enough to make it wide angle,  haha.  Joking aside I think unless he needs the 2.8, some options he could go is the 24-105 IS is a great all around lens, he could get that, and then as neuro mentioned in a prior post, pick up a 10-22mm EF-S lens... or you can get a 10-20 sigma, or equivelent tokina or whatever... those are good for crop bodies such as the EF-S and if and when you even move on from the crop body (7D, 60D, Rebels, etc)... and move to full frame like the 5D and 1Ds, then you only have to sell 1 lens, still have a good all around lens, and can use the money from the sell of the ef-s lens to buy whatever gear you deem appropriate at that time.  That way he's not being forced into buying additional lenses JUST BECAUSE he is upgrading bodies, unless he wants to.

In that mindset, having the 24-105 and 24-70 makes no sense.  Personally I would go with the 24-105 instead of the 24-70, unless perhaps the 24-70 IS comes out, however unless that happened, I wouldn't bother. 

I can see some sense to it - the 24-70mm provides an extra stop of light, which in some situations is critical.  Personally, I've recently done some shooting in the evening, when I wanted the flexibility of a zoom, had moving subjects which negated the benefit of IS, and ISO 3200 with the f/4 of the 24-105mm wasn't doing the trick - one more stop would have been enough to stop the subject motion and bump the keeper rate to something acceptable.  I've considered the 24-70mm, but would really like an IS version of that lens.  If I had both current lenses, the 24-105mm would get more use, I'd bet.

Well shoot assuming money is no issue, then yeah, get as many lenses as you can, however as he is starting out his gear, I wouldn't recommend jumping out and getting both lenses within his first few lens purchases until he comes into the situation (and have enough training to know the difference) where he would want and need a faster lens.  Even at that, 2.8 is only 1 stop faster and at that point, he may even want to consider a fast prime or two to combat that situation (my original recommendation for his 4th purchase).  Its fun spending other peoples money, haha.  =)

Ii would skip the 24-105 and go for the 24-70 and if you like, go later for an 70-200 or 70-300.
I think it makes no sense, to have two lens in the same range. But depends on you needs.

I believe I may have mis-spoken/mistyped because I reread the thread and he mentioned he was getting the 24-105 and then going to later buy the 24-70 and you said having 2 lenses in the same range made no sense and I replyed nonsense... I guess i misread and thought I read his third purchase was a 70-200... (saw 70 and went in that direction in my mind)... In that mindset, having the 24-105 and 24-70 makes no sense.  Personally I would go with the 24-105 instead of the 24-70, unless perhaps the 24-70 IS comes out, however unless that happened, I wouldn't bother.  I would recommend he got the 70-200 F(whatever his budget can afford(2.8-4)  on his third purchase instead of the 24-70.  That way he has a mid, wide and tele.  Then maybe adding a 50mm 1.4 or 85 1.8 or some large aperture lens down the road for the misc shooting conditions when f2.8/4 aren't wide enough.  With those 4 lenses he should be good in my guestimation.  Also avoiding EF-S lenses may work well if he's hoping to upgrade to FF in the future.

... it's a good think i'm patient and my money gets to compound interest until it's announced/released.

Where do you get interest on your money these days? :P

Inflation and rising prices seem to overwhelm the paltry interest rates.

I've got my options... =)  hopefully this camera will arrive when i'm young enough to do stuff with it, haha.

Nonsense... The only reason to go for the 24-70 is if you want the extra speed, no stabilization, and a bad back carrying the beast.  It's a good lens but the 24-105 is a very good all around lens with ok wide end (36-170mm roughly) and decent long end... Then he can throw on the 16-35 and 70-200 for situational photography.  That's the route I am in motion for going with Full Frame, i just need the friggen 5D mark III to come out... it's a good think i'm patient and my money gets to compound interest until it's announced/released.

Lenses / Re: Sigma 24-70 2.8 hsm vs Canon L
« on: June 28, 2011, 01:23:20 PM »
I'm going to guess that Flake means using a 77mm filter on the 82mm-threaded lens (whether you call that a step up or a step down is semantic, in that different manufacturers would name it differently). 

Looking at the front of the lens, it does seem that there's a bit of room to spare.  That's true in many cases, for example, mounting a macro flash on the EF 100mm f/2.8L Macro IS or the EF 180mm f/3.5L Macro lenses requires a Macrolite adapter, which is essentially a 67→58mm or 72→58mm step-down ring, respectively. 

The Sigma lens already suffers from a fair bit of optical vignetting, but a loss of 5mm might not add any mechanical vignetting to that.

Sums it up I guess!  although the 5mm is a diameter loss so it means a loss of 2.5mm on each side

It varies from lens to lens I suppose... for instance there are some lenses which i've heard can give vignetting just putting on a regular filter, hence why they sell low profile filters... I dont have much experience with this lens in question... while adding a step down ring may not add much to mechanical vignetting, adding a filter, or two or three (depending on what you are adding) may become a problem... Regarding the macro rings... since there is a sense of telephoto in those zooms, I think they may either add a fraction more glass so it's more consistent edge to edge but you can also easily utilize such attachments.  I think (going off assumption) it may be more of a marketing and engineering factor with "macro lenses" or else they would have to utilize another style of adapter.  Perhaps someone who has this sigma lens can try it out for the benefit of this forum and we will be eternally grateful.   :)

Just buy a step down ring 82 - 77mm isn't a massive difference and £2 finding out if 24mm vignettes (which it does anyway - lots!)

Don't you first have to buy the 82mm filters to use a step down ring, unless you mean a step up ring?

I believe that's what he meant... I would be nervous on vignetting on the wide end but if it work, then great..

For the best comparison of these two lenses, go to the the-digital-picture.com  You can in the 12233 chart put the two lenses side by side and look at sharpness and such... the 24-70L outpreforms it, especially in the corners, on all focal lengths... center sharpness tends to be a wash/maybe even a slight edge at times with the sigma, but the corners fall apart.  Lastly, on their summary of the lenses, they said if sigma was the same price as canon, NOBODY would buy the sigma, however since it's half the price, it's something to consider.  It also mentioned if you get flare, even a little flare, you lose a ton of contrast in your entire image.

Sigma also has some sample to sample issues such as some lenses have been shown to be sharper on one side than the other, and CA (purple fringing) leaves some to be desired at the edges.  With that said, prices especially for canon lenses have risen to the MSRP since the earthquake in japan and in some stores, there are also backorders.  As flake said, if you can wait, at least until maybe the fall when the fall/winter rebates start rolling out and production gets fully up to speed for canon, that may be the best situation all around.

Indeed, the lens selection is one of the more important facets of photography, as well as practice practice practice so you learn how to make the most of your tools.  You have a nice selection of lenses... on the wide end you can pick up the 16-35 which is a very good lens, however if you are also considering, the 17-55, both F2.8, they are a bit redundant.  The difference is primarily the 17-55 gives you a tad more reach on the 55 end than 35 on the first lens.  Also the 16-35 has a metal body and weathersealed whereas the 17-55 is a strong plastic and not weathersealed.  If you're kinda rough with your gear, then the 16-35 may be the smarter option, however the 17-55 would be a good all around lens, just dont bang it around too much.  Also, the 17-55, i'm not positive if it comes with a lens hood, (the 16-35 does, all L lenses does), and on the 17 end of the lens, you will want a lens hood to prevent sun flare.  I would also consider the 2 fast lenses... I'm not well versed on the 28 1.8, however the 50mm 1.4 is an old design and there have been rumors for years about it getting a facelift, however it hasn't come to be yet.  It also has an old AF system which requires patience.  Anyone who has the 28 1.8 that can vouch for it?  I'm not sure if it has a micro motor AF like the 50 1.4 or if it's ring usm.  If the AF is better, then I'd recommend the 28mm.  If you wanted a 3rd lens, you can add a 24-105 L to add a bit of reach on the long end.  The 70-300's tend to be a tad soft unless you get the latest IS version... I've heard of happy owners of that lens however people tend to love or hate this lens.  For the same price of that lens, you can get a 70-200mm F4 L lens.  You lose some reach but get a better construction and very good optics.  Dont forget to practice practice practice to learn to make the most of your gear and prevent buyers remorse.

EOS Bodies / Re: What do you want from the 5D mk III
« on: June 27, 2011, 02:17:55 PM »
Most of you have focused on the technical abilities of the camera.  I'd like to focus a little on its usability:
1)  Reset the selected focus point to ‘All’ by, for example, pressing the focus point selection button twice of something like that.  I believe that some Nikon’s have this feature
2)  I’m amazed that we can’t natively embedded the GPS coordinates in the pictures we make.  BTW, I don’t want to sacrifice my hot shoe for this since I take many pictures at night.
3)  I would like to be able to secure my camera (and lens by the way) using a computer cable lock.  I often shoot time-lapse photography at night.
4)  Greater than 3 selections when bracketing a shot
5)  Dual card format (SD and CF).  SD cards are significantly cheaper than CF ones which can be more performant. 
6)  I’d love it if the camera would move pictures from the CF to the SD card automatically when the CF card is getting full.
7)  A setting to automatically set the camera settings so that it can get as close as possible to the maximum number of frames per second.  When I’m looking to take a very fast burst of pictures it takes me a few minutes to tweak all the settings just right so that the camera can get as close as possible to its theoretical maximum FPS.  I know I can select high-speed shooting, but depending on my settings (RAW, Av, etc.), I don’t even get close to what I should be able to get.
8)  Provide feedback on sensor temperature during long photo sessions at night – I would like to know when I’m degrading the quality of my picture because the sensor temperature is heating up.

Michel

ditto what neuro said on 1 and 7... However I do hope that the 5D inherent the 7D multifunction button and customization where you can assign each button to a function it wasn't originally assigned so if you want your 1 shot FPS thing, you could assign it that speed mode.  I wouldn't mind dual CF slots and I could change my mind later, but I'm just not sure about different card types in terms of buffering, when you exhaust 1 card how it impacts the 2nd and will there be a lag inherent on the SD cards verse the UMDA CF you may have in the CF slot... I wouldn't find GPS at all useful, I've never fully grasped what the need of having GPS unless you are scouting locations or such... Laptop kinda lock, eh... ok... I've seen many youtube videos of them ripping out of laptops and being easy to pick off... however if it provides peace of mind, then great... 

With that said I'm not bothered about what MP it is as long as it's at least 21mp and shoots faster and has better AF such as the 7D if not better.  I dont want as strong of an AA filter that has caused the 5d MII to have the reputation of having soft/smeared images to reduce noise.  I want a native 50 ISO so the images would look even better on that setting rather than a native 100 ISO with an underexposed iso 50 which isn't much better quality wise than the 100.  High ISO i'm not too bothered about as long as it's usable from ISO 2000 and below.

I've still got the 450D, but hardly use the 70-300mm, so my advice would be to get a decent walkaround lens with a body, don't buy a body with a kit lens, it's gonna end up in your camera bag forever once you get a decent walkabout.  Then after several months, check your images, are you going long or wide, landscape, sports, portrait, etc - once you figure out what you take photos of, use the remaining money you have to service your lens and filter needs.

I agree with most everything you said... a couple things to think about is lenses, on average, especially really good ones, will stay in your bag for many many years (and camera bodies for that matter)... You can get a kit lens and "learn" but they tend not to keep their value once your ready to upgrade and it (especailly once you move on and can compare better), aren't as good of lenses. 

Personally I like the xxD series over the rebels because of the LCD's, ergonomics, size, etc etc however it is a personal matter and perhaps thats where you should go to a camera store and hold the different bodies, do your research and find out the differences and weight the price differences to see if for an extra $100-200 a top LCD, stronger body, ergonomics, etc...is worth it for you or not.  To some it will, to some it will be seen as a simple "splurge"... Only you can answer that.  Lastly bodies get replaced every 12-18 months (for consumer grade bodies) and lenses on average can go much much longer before upgrades, sometimes decades, see the 17-40mm L.  If you had the option in your budget, spend more money on lenses than bodies.
