Lenses / Re: Low Light options
« on: August 23, 2012, 10:02:13 AM »
The flash would still be a better option for wedding situations, where the rooms are dim and you're often taking group shots.  Ideally, you would like to get both a flash and the Sigma 30 to cover your bases.
For the pro hired to take the pictures, yes. For a guest just taking snapshots; flash is a good way to piss off people. I agree that there are situations where a flash will be nice (birthday parties, events, etc); but there's also plenty of times where its not socially acceptable; or worse, where your flash will actually ruin other's photos.

My question is, if I had the 17-50 Tamron f2.8 nonVC for indoor use how much would it of improved my ISO or pictures?

Here are some examples:
1.  Some of the really dark pictures from the rides I was at f3.5 at 3200 ISO and they were still not great.  What the f2.8 of been able to capture the shot?
2.  If I had indoor pictures at 3200 ISO from f4 to f5 then with the f2.8 what ISO would I get and would I be able to avoid using a flash?
Well, the difference between f/2,8 and f/4 is one stop. So, if you're shooting 3200 ISO and f/3.5 and f/4, then you'd be shooting at ISO1600 with the Tamron. Maybe ISO800 on shots you took at f/5.6.

Some things to consider; if you are taking more posed shots (not kids running around, etc) then IS would allow you to lower your shutter speed by 3 stops or so. But, if its for moving subjects, thats not help. Likewise, an f/1.4 lens would represent a 3 stop improvement over your current lens, and f/1.8 is a little more than 2. Those are big enough differences that you'll either get faster shutter speeds (less blurry shots) or be able to shoot lower ISO.

If you like your 15-85's range, then a prime or two in that range is probably your answer. The 50mm f/1.8 is cheap, the f/1.4 version would be even better. As someone mentioned, the 28mm f/1,8 would be good for shots that are a little wider, and the 85mm f/1,8 would be good for closer in shots. I'd see what focal length you use the most and grab that first.

As for using them on a body that doesn't AFMA, then you want to either be able to test it out before hand or buy it from somewhere that allows easy returns. Or, send it in to Canon to calibrate.

You have used surprisingly low shutter speeds. I was shooting around 1/1000 of a second so as to avoid motion blur.
Yeah, generally speaking, when I am shooting wildlife, I am putting the lens on the fastest aperture possible, because I am both trying to isolate the subject and avoid motion blur. That same shot at f/4 would still have the tree and squirrel in focus, but the background would be much more diffuse. The green area would be completely blurred, and even the limb behind him would be much more blurred. That would isolate the squirrel more where he now blends with the limb a little. And your shutter speeds would be more like 1/100th of a second, which would save you from getting blurred shots if he moved.

The big thing is background choice. I know this is damn near impossible with something that moves so much like squirrels, but if you were 3-4 steps right and crouched a little, there would be more green which would isolate the squirrel more and make him stand out

TRON: my needs are: portrait, food and indoor locations (as in restaurants) and concert.
          my equipment is: 40D, Canon 50mm 1.4, 85mm 1.8, 60mm macro, 17-55mm 2.8 and 55-250mm; Sigma 30mm 1.4 and 10-20mm 4-5.6... so I have a bit of investment in crop.

5Diii would be a dream, but not sure if it's realistic looking at my budget and if it would be overkill for me. I'm an amateur after all…
Sounds like you have a decent plan, but, aside from the concert stuff, the 5dIII would definitely be overkill for you in terms of AF. The 5dII AF would be the same as your 40D, and you'd be gaining probably 2 stops of light just by that sensor switch. But, based on your investment with EF-S lenses, and what you are shooting, I'd say spend all the time between now and October learning flash. You need it for portrait and product photography anyway, and it might take away the need for full-frame, allowing you to keep those lenses.

The good news is that you have enough lenses that moving to full-frame wouldn't hurt you. Replace the 60mm macro with the non-L 100 and your prime lineup would be set. And a 17-40 would probably take care of the gap left with the 10-20, if you use that often. Either that or something like one of the non-L 20, 24 or 28mm primes, if you need low light wide angle shots for the concert. But chances are flash will help clear up your need for quite a few things; I shot a friends wedding with all f/2.8 glass (and the 50mm f/1.8), and with flash, I didn't need anything faster

Not to hijack your thread, but where do you plan on selling the EF-S lenses? I have a new 17-55 2.8 IS that I want to unload and didn't have much success on Craig's List and some UK scammer tried to buy it on EBay ...
FredMiranda, PotN, basically any photography forum with a buy/sell forum. Scammers are a lot less frequent there, though they do still exist.

JMHO - Since there was no mention of any video features, maybe to keep costs down, this will be a Photo Only Camera??? Good for Landscape and Portrait type work, than it really won't see much video work.

Thoughts?
Video costs Canon very little to implement. Seeing as Magic Lantern made the 50D a camera capable of recording video, I can tell you that the implementation is fairly cheap software. It may not be amazing video, but its video. If you would be fine with the camera not having Live View, then sure, they could possibly leave video out and save some money. Otherwise, once the tech is there, the choice to not record video is just silly and saves them nothing. But it does cost them buyers (a bunch might but the video-enabled D800 instead), and that means a higher price on the camera. Chances are Canon would have to charge 20-30% more for a video-less camera, which is why you will probably not ever see one

Does anyone know what the RAW file size would be? 
Well, for the D800, a 14 bit uncompressed RAW file is 75mb according to Nikon. And that is off a 36MP sensor. A 45+ MP sensor, you're probably looking at 100+mb for a RAW file, which is about quadruple what the current file size is. That adds up very quickly when you are shooting 100's of images at a time.

Is this just a defensive rumor started by Canon to stop people from defecting to Nikon and buying the D800?
I doubt that. Anyone who wanted to defect would have already, since they've had several months to consider it. The D800 is real, a Canon variant isn't, for someone who needs the MP, they've moved already. Especially since there was no indication Canon was gonna match the D800 in price.

Price I think will be $5000 - $5500 and for the designated user, I think is very reasonable.  I think it's going to dust the Nikon D800, but should NOT be direct competition due to the price difference.

For the full-time pro, I think this camera is a huge home-run.  I'd consider picking up this camera in a couple of years unless Canon comes out with a medium format camera....
Yep, these I can see being about right. And I think Nikon actually made a mistake pricing the D800 so low. There are quite a few people that switched because it was affordable to do so, only to realize they didn't need or want 36MP, and now they are changing back. I've seen it a bunch for wedding/pj types, where the hassle of the extra storage and extra processing isn't worth it

Lenses / Re: Canon EF 40mm f/2.8 STM Firmware Available
« on: August 21, 2012, 02:37:20 PM »
Why can't other bodies handle the FW update?
I'm guessing its a function they just recently added to their software, and its not in any camera they released before 2012?

Makes sense really, as it would save them a lot of repair time for something like this if all their bodies could just download the firmware

I'm in the reusing the 1d name camp....   we have 1DC, 1DX, 1DM - for "Max" to allude at "medium" format quality at FF sized sensor.
The "M" name is already taken, that's their mirrorless cameras (EOS-M). It'd be a nightmare for them to put out a 1DM that isn't mirror less, definitely confuse a lot of people. It would be just as bad as naming it 3D. Since they already have the legacy of the 1Ds, I'd go with that.

"Industry leading ISO Performance" limited to 6400 native  :P
Amazingly, in quoting that, you managed to remove the word "low" from it, which makes all the difference

1Dx is nice but I'm not quite there yet with income.  I think 5D3 is the direction I'm leaning.  I found this seller on eBay.  It looks like he breaks up the 5D3/24-105 kits and sells separately.  <$3100?  Usually, if it looks too good to be true, it isn't. It looks like he's sold quite a few.

http://www.ebay.com/itm/Canon-EOS-5D-Mark-III-Digital-SLR-Camera-Body-NEW-/150811558362?pt=Digital_Cameras&hash=item231d11c1da

Thanks

Canon has a specific list of retailers that are "authorized", meaning that you get the warranty for a full year. I know GetItDigital is not one of those, and many of the Ebay sellers are not either. For a $3000 item, not getting a warranty would be unacceptable to me. The list is at the bottom of this page: http://www.usa.canon.com/cusa/professional/standard_display/where-to-buy-pro

There are a few that are tricky (ASavings on Ebay is actually Focus Camera, which is authorized, for example), but for the most part if you don't see them on the list, the "warranty" they offer is dependent on them actually backing the product, not Canon.

It also appears that Ebay has authorized resellers pointed out, as they do in this listing in the top right corner: http://www.ebay.com/itm/Canon-EOS-5D-Mark-III-BODY-Digital-SLR-Camera-Canon-5260B002-NEW-/170846708911?pt=Digital_Cameras&hash=item27c741e4af

Have you tryed one of those little rocket blowers? might end up on the sensor by the time you are done tho, thats always a risk of blowing in the body
I actually tried messing with it a few different ways and was never able to get it to move. Mine is in the upper left corner of the frame though, so, it basically never messes with my composition

EOS Bodies / Re: Canon EOS 7D Mark II Specs? [CR1]
« on: August 20, 2012, 01:37:56 PM »
The current 7D is still usable at 3200 ISO, if you use raw and some NR in f.i. LR afterwards imho...
[/quote]Oh, I agree, but, the 1DX gets about the same results at 25600; it basically is a full 4 stops better than the 7D sensor. Which is understandable when you consider one is a 3yr old APS-C sensor and the other is the top of the line full-frame sensor.

My point was that I don't expect Canon to have any worries about whether a 7DII has 1DX features, because its low light ability will never be able to match it.
If Canon were listening to what photographers want, how near is this specification to what 7D users have been asking for in a MkII ?
Well, if it does video at 1080/60fps, it'd be more than most users were expecting. The fps and AF are about what most expect, and the sensor sort of goes either way. I think most wanted an improved 18mp, while others wanted more or APS-H.

If that spec list is true, it'd be a well embraced camera.

I hope the 7D MKII will inherit the 61-AF
- 61-point AF with up to 41 cross-type AF points
- ISO up to 25600 and Less high ISO noise at 6400 (would be great if that would be even 12800)
- dual slots
I do think they will have to reconfigure the whole 61pt AF system, since its a smaller image circle they are dealing with. It may well end up as a 41pt AF system (removing all the outside points), but with all cross-point or mainly cross-point. A stop improvement on the sensor would be nice as well.

Give it the same build quality, a better sensor, faster, better AF, and it sounds like a win. And maybe a nice option when fall 2013 comes around

If you're seeing actual small specs, it's unlikely to be on the mirror, since the mirror is not a focal plane (much like a speck on the front element, it won't resolve as a discrete point).  Rather, the dust is most likely on the focusing screen (the accessible bottom or the inaccessible top).
I have the same issue, a few specs of something in the top left corner of my view-finder. Since it has no effect on my images, I've decided to leave it as it. Not worth the cost of cleaning/repair to me since it has no effect

So it would have a higher res than the 1Dx and just 2fps less?  That is the part I don't get.  I think the 7D is due for replacement, and these maybe the specs, but if they are, I don't see it getting here till mid next year.  1DX supply is tight still, eh?
We're talking entirely different sensors though. For outdoor sports shooters who get bright sunlight, sure, there might not be a big difference. But then again, the current 7D would probably be fine for them (though the AF upgrade would be nice)

But for anyone working inside or in lower light, the 1DX sensor can shoot comfortably at ISO 12,800 and even 25,600, and the current 7D struggles at ISO 1600. Even assuming they get an extra stop out of the 7D sensor, its still well behind.
