Software & Accessories / Re: What size RAW should I shoot at?
« on: August 02, 2013, 08:11:02 PM »
Why invest in a full frame, 20 megapixel camera if you don't take advantage of it?

Exactly my principle (although I do not have those great cameras). Now a days memory cards are not that costly I think (at least when compared to the price of the camera into which it goes).

I try to get the best out of my equipment - so full RAW it is always. May be today I do not know that much processing but tomorrow I might learn better processing. Then if I do not have the full resolution file I shall not be able to do anything. I am not that good photographer so out of every 100 photos that I shoot I generally finally keep only 20 to 30 photos. So ultimately it is not that memory hogging exercise either. While deleting my principle is if at the computer screen the photo does not look sharp or does not please me compositionally at the first sight then it goes.

EOS-M / Re: EOS M or T3i which one?
« on: August 02, 2013, 01:19:33 AM »
I do not have either EOS M or T3i (I use 40D/50D). So cannot tell you anything about the image quality. But I have another point. I have been reading that Canon is not even introducing a particular lens suitable for the EOS M in the US market. So I wonder how much canonusa is behind this camera system (EOS M). In any case it is a new system, and so there may be first adopter's disadvantages associated with it for the next one or two years.

Thank for sharing your experiences.

@Mount Spokane..... Thank you very much for the warning/pointer. I will surely keep that in mind.

Third Party Manufacturers / Re: Sigma Announces Mount Conversion Service
« on: August 01, 2013, 12:32:36 PM »
My guess is Sigma is expecting to introduce some very good DSLR in next three year's time. But meanwhile they want their current wonderful line of lenses to proliferate (at least among the amateurs and cash strapped enthusiasts). So that when finally their great camera comes in some can be tempted to change over to Sigma. Sigma (my guess) does not even want people to change from Canon to Nikon or Nikon to Pentax. But rather they are wishing that people will changefrom Canon, Nikon, Pentax (users of those cameras who bought Sigma lenses, not those who all use only their own manufacturer's costly lenses) all to Sigma (when the expected future great Sigma camera comes into picture). Meanwhile is some Canon users with Sigma lenses change over to Niikon (or the other way round) that does not really matter to them.

I cannot say for sure but my guess is when the first lenses were being made in the 1800s for medium and large format cameras the photographer scientists manufactured lenses with whatever focal lengths their state of the art technology allowed them to be made. Then those focal lengths became standardized because others also made similar lenses. Each of these focal lengths gave rise to a particular angle of view. Then probably when the 35 mm camera came the lens makers tried to emulate those angle of views and some particular focal lengths became manufactured repeatedly and became popular and then standardized. But all these are my guesses.

Canon General / Re: People that don't shoot in manual...
« on: July 30, 2013, 04:13:51 PM »
It annoys me immensely when people keep on wasting time on useless forum posts instead of actually taking photographs.... Now I am annoying myself.....

Just wondering if any of you have used either of these older lenses from Sigma .... internet reviews say they were good, but just wondering if any of my CRian friends have firsthand experience with either of these two (by off chance)....


143
One reason may be that it is for a lens which is now outdated (400 2.8 mark I). The newer lens (mark II) seems to use the ET 155 WII hood which is worth 700$ in US. And the second reason is that the lens which takes this hood is 11000$ worth.

And to put it into perspective (may be I am stretching it too much). The hood for Canon EF 85mm 1.8 costs $26 while the lens costs $419 (right now) which is around  6% of the lens price.

The $700 hood for a $11000 lens is also approximately 6% of the lens price.

Software & Accessories / Re: Macro gear suggestions for 5DIII?

If Roger/Lensrentals says it, you can believe it.

Right, actually I saw later that it was blogged by Mr. Cicala originally. I added the last two line (lensreantals reference) later as a modification to my post. That is why I was not sure about its correctness when I first wrote it.

Would you happen to know how the Sigma f/2.8 150mm or 180mm macro lenses fit in with the Canon AF rules?

Sorry, no idea.

I found this website
http://www.imaging-resource.com/news/2012/06/18/5d-mk-iii-af-points-and-third-party-lenses

Sigma 150mm OS is group E

Not sure about the veracity...

Originally it was probably published in Lensrentals blog

I'll second the usefulness of a longer lens.

I picked up a gently used Canon 180mm macro and I find the added working distance to be helpful. Less shadowing for sure when getting in close to fill the frame.

I suppose the only catch may be that different parts of the 5DIII AF system are used because the 180mm is f/3.5 and the 100mm is f/2.8.

The Sigma lens with OS might be nice- one thing I miss comparing the Canon 100 to 180. I may have to rent the Sigma and see how it works.

@danski..... first up my confession that I have used neither of the following lenses. But....

Since you mentioned that you miss OS with the 180mm macro, try out the Sigma 180mm f/2.8 OS.... I have only read that Sigma 150mm is very good, however I have not read that much about this 180 f/2.8 OS macro from sigma. I could not find either of them at my local lens rental place. If you have the chance try it to see if it performs as well as the Canon 180mm but with OS.....

I have the 5DIII and will probably get the 100mm 2.8L IS, and I'd like to have a hand-held macro setup but not sure the best approach.  I already have two yongnuo speed lights.  I have 4 triggers and a few sync cords so they can be used off-camera...

I've seen those contraptions that look like a ring that attaches to the body, and speedlights can attach and be moved around.  Is that the best route to go?  Is there something else to consider? Any specific brands/products recommended?  A better way of going about it?  Any tips in general?

Although probably you have fixed your mind on EF 100mm 2.8L, but since you are going for handheld a little bit of more working distance can never hurt. So have you thought about Sigma 150mm OS 2.8 Macro?

PS: although this might not be a great plus, but I see that Mr. Neuro has said that for the Wimberly  F2 bracket needs a lens with lens collar (which EF 100mm 2.8 L does not have to start with and you need to buy separately). The Sigma 150mm 2.8 OS has that lens collar out of box :)

Lighting / Re: Upgrade fun...

That is a good steal. Heck, that is even better than a steal..... that is almost a bank robbery.... :) enjoy....

If I was in the market for a full frame I could grab a 5DII for $1300 bucks today (saw on craigslist just now)...... seems interesting. Or for that matter a 7D for $800.

Lighting / Re: Guess what?
« on: July 22, 2013, 04:35:27 AM »
If you're shooting with a 135mm prime lens (non-IS), and your camera max shutter sync speed is only 1/200...that's not a lot of wiggle room.

It is too cryptic.... could you elaborate the situation you are facing a little bit more?

Lighting / Tested true freedom yesterday
« on: July 21, 2013, 05:06:30 PM »
Yesterday I was going to a friend's place to visit. This friend has two one year old twins. So I took my camera with me along with the recently bought four YN 622Cs. I do not have any ETTL flash, so I put three Nikon SB 28DXs at 1/2 and 1/4th power on top of three bookshelves directed towards the ceiling. The walls were coloured, so the white ceiling was my best bet for reflecting the light. Now, earlier I used to use cables to fire my flashes remotely, and that was cumbersome and clumsy. Boy, yesterday with the four YN622Cs (one on top of my camera, and the other three with the three SB 28DXs) it was so much easy and fun photographing the twins. I was not going for any dramatic lighting, I just wanted enough soft light to use a shutter speed fast enough to capture the twins's activities indoors (and the sudden moments like the photo below where one of the babies falling down after throwing a tantrum). It felt so great just to be able to reposition the lights without breaking a sweat. Some photos from yesterday attached. (Now I need to learn a bit of more post processing) Your comments are most welcome.

PS: YN 622Cs are my first remote flash transceivers. And they seem to work just great in manual mode.
