Macro / Re: Reverse a lens for macro.

You could also use an old EF 35-80 kit lens (they came on old rebel film cameras) & remove the front element. This gives you a crazy "zoom" macro that I believe goes beyond 1:1, but with no auto focus or working distance. If you just google "Canon 35-80mm macro mod" a bunch of things come up. You could but that lens for next to nothing.

Yup, got one of those also, but I prefer the 50/1.8 with extensions.   The modified 35-80 is almost a microscope.  I realize saying this might be tantamount to sacrilege to 'L' aficianados, but stopped down the 35-80 takes acceptable daylight photos also (as a normal lens)........not every shot needs a 24-70.  Think I paid 25$ for mine.

I prefer to use extension rings.  I found a very inexpensive set at a department store photo section.  They're just tubes with electrical connections, no need to pay Canon price for them, and they'll work with any lens I want to use, including an old manual SMC Takumar with an adapter.

You (OP) said nothing about price......therefore the 70-200/2.8II IS is the one, no question.  If you can, just get it.  If you have to stretch or wait a little while, it's worth it.  If it's out of the question for now and you don't want to miss shots, there are a number of very good compromises, sort through the ones recommended in the responses.  Can't go wrong with an L prime if that's the choice.

EOS Bodies - For Stills / Re: Resetting the shutter count
« on: April 04, 2013, 08:51:36 AM »
I perfectly know that in Canon they sell refurbished cameras with shutter count of 0

?????  I've bought refurbished from Canon, shutter counts were low but non-zero.  Wouldn't make sense for Canon to sell a refurb with zero shutter counts.  If anyone tried to tell me their camera had zero shutter counts I'd call shenanigans and refuse to deal with them, whether Canon or individual seller; it's like rolling back an odometer and says more about the seller than the equipment.

A standard technique for astrophotography is to take what are called 'dark frames'.  Not specifically applicable to your single exposure Milky Way photos, but still might be worth a try.  works like this:  A series of (let's say) 3 minute exposures are made of a galaxy/nebula/cluster or what have you.  From 'several' images to hundreds - these are called 'light frames'.  A series of dark frames are then taken by covering the lens and viewfinder and opening the shutter for the same amount of time used for the astrophotos - maybe 5, 7, or 9 frames.  (I use odd numbers because folks tell me I'm odd....)  The dark frames are averaged and that average image is then subracted from EACH of the light frames.  There is more to it, but that's a brief description.  Two free programs that automate much of the averaging, alignment and stacking are (my preferred) 'Deep Sky Stacker' and 'IRIS'.  There are others at various price points.  There are lots of variables to consider, for one, the temperature of your camera will gradually rise during an imaging session and plateau at some point - might take 30 minutes, might take two hours.  In-camera noise reduction is not usually very good for astro.

For sure those two are great value.
I know some will groan when I say this but for now I'd like to keep to the 'all Canon' theme.
I'll maybe stray from that path at some point down the line though. Most likely starting with a siggy 35 next year sometime.

Makes it simple then,  24-70II and be done.  I think you already knew this, though.   ;)

Get the lens now.  Wait and save for a while and then get your very understanding and patient wife the 1DX "she's always wanted".

You're welcome! :)

EOS Bodies / Re: Future of APS-C Given 6D Pricing
« on: March 27, 2013, 09:46:55 AM »
7DII will be the kundalini of crop cameras, 'professional' in every way.  I'd be surprised (shocked) to see it come out a penny under $2700 US and would not be surprised at 3K+ at launch.  Might not have the low light ability of 6D/5DIII...but it will be an exceptional camera.  Worth waiting for if you're interested in such a camera.  In the range of what I would spend, but with a 60D and an astro modded 40D my crop needs are met.  6D/5dIII and some glass/lighting gives me more bang for my buck.  I think we're past the point where Canon/Nikon need to blow each other out of the water on an annual/biennial basis.  Both companies make exceptional equipment.  IMHO, they could both get out of the P&S segment, I make phone calls with the last P&S I'll ever buy.

"Just a hunch about pricing, it won’t be cheap."

 ;D ;D ;D ;D ;D

Hard to know what will be more interesting/entertaining - the equipment or the forum screaming over the price.  The lens will of course be priced in the stratosphere, the 7DII will be shockingly high also.  To make up for the crop factor, it will be priced at 1.6x what many would consider reasonable or expected.  And likely worth every penny.

I forgot to mention i do have the 50mm 1.8 canon but i feel it is a odd length for me i feel like its too long. I am borrowing this lens (the 17-40) basically until i buy the next lens. I am on a limited budget i basically have enough for one lens. I have about $1350 at the moment

If you feel 50mm is too long on your 6D, then you will likely feel the same about the 35 on your T3i.  I'd go for the Tammy.  After a few months, see if you've developed a preference - where you've used it the most (i.e., wide or tele end), and base your prime lens purchase on that.

Lenses / Re: 24-70 2.8 or 24-70 4.0 IS ?
« on: March 25, 2013, 09:12:13 AM »
EF 2.8 is optically better, EF 4 has IS.  Tamron is no slouch optically, is 2.8 and has IS.  At least for me, it's an easy decision.  You wouldn't go wrong with any one of the three, actually....but the Tamron might be the only one capable of getting the shot in extreme conditions.  Added bonus - if cost is a consideration the wallet impact is reasonable and I wouldn't consider the lens a compromise.

From Roger Cicala at LensRentals:

"The 800mm f/5.6 is also the photography equivalent of a D cup- not a necessity, but wherever you go with it, you’ll make lots of new friends."

Hands down, best summary description I've ever read.  Still have dried coffee in my keyboard from reading that.

This might be a bit soon, but.....does anyone have experience using this device/app with Android tablets?  I've held off on CamRanger because I'm not willing to get an iPad when my Acer Iconia A500 is working fine (though the Retina display is quite nice).  Wireless is very much a plus for me and the primary reason I'm considering the 6D over the 5D3.  iUSBportCAMERA could sway my decision.  I also use an astro modded 40D and a soon-to-be-modded 60D. I'm a patient person, my camera purchase is a couple months out anyway.  CamRanger's website implies that Android support is 'coming soon' but I don't see any progress noted.  Sanho has been very upfront about the lawsuit re: CameraMator and seems to be very proactive in responding to the market.

Here is a nice short review of hands on with a pre-production SL1.
'twould be a good astrophotography camera if modified.  I have eyepieces that weigh more.  The shorty forty looks BIG on the SL1!

....This is a bit like complaining that the Toyota Yaris 2013 is pretty much identical to the Toyota Yaris 2012; cars get yearly release, even though significant changes are only made every now and then.
And for a lot of folks, that Yaris is just fine, does what they need.  There are appropriately priced high-end models available for those that want them.  The car-camera analogy is exactly what I've been thinking.
