still not sure what conclusions to draw, especially regarding accuracy with wide apertures.

It is actually quite simple. You can only use the middle AF point and then recompose = getting an OOF photo. Servo tracking may work for the center of the frame but a person's face usually is not in that spot so it's useless to track people that way.

8-15L ... Why not?

:) It's my latest addition to my set and I love it. I wonder how long it takes to finally get a decent shot.

Looks good. Could use more DOF though.

The Silver Lining of Storm Janus by btaoka, on Flickr
The Russian guy's snowflake photos have more DOF and detail to them, but this was taken from my 100L macro (i.e. 1:1 magnification), no focus stacking, just a single shot.  No special lighting either, ambient light used.

Decent quality there! Why did you do as the Russian and put the flakes in some pubes or something similar? That was the only thing that bugged me in his photos when I saw them the first time.


In Tv mode, it's nice when shooting a fast lens to be able to set a max aperture to maintain sufficient DoF, for example.

Then again, M mode with exposure compensation would more or less make the other modes pointless. Oh... 1DX has that too.

Why do people post photos on social websites?

A very good question! It amazes me how easily people post up photos of their kids too. I for one like to protect my kids from that kind of crap. I can't think of a thing to gain by posting up those photos. There is a S___ load to lose...

1) shoot RAW
2) transfer files to computer
3) pick the good photos
4) edit the picked photos and delete the rest (Wish I had always done this. Deleting bad photos leaves you with plenty of unimportant files and deleting them later on would require a vacation just for doing that.)

Seriously though, I haven't found a decent work flow on Mac. I had a crappy but functional workflow, but Mavericks made that impossible. Now I'm left with a painful procedure.

If I import straight to Aperture, there is no good way to back up the files. Or if there is, I have not discovered it. Aperture also clutters the SSD. There is no way to have everything available. There is also the possibility to have the RAWs on external drives, but then I have nothing on the Mac I carry in my camera bag.

EOS Bodies / Re: Will the next xD cameras do 4k?

I really hope there won't be 4K recording. Resolution is not even close to being the main issue. Functional focusing for video would of course be much better than a higher resolution. Then again, there are video cameras for videos.

Ok, I don't get it. Explain ti to me, all you lens cap photographers!

How can you not notice that you have a lens cap on? When I stare through the viewfinder of a DSLR, I most definitely notice if a lens cap is on. So do you just shoot like Arnold [akh-nuld] without aiming?

And to those who take pics of the cap on purpose, you could take the same shots with the cheapest equipment out there! ... If you have no life, there is no killing you, eh?

It stays a lot on my (camera) body. It would be a perfect lens if the AF wasn't so inconsistent. AFMA helps, but doesn't change the fact that the focus works differently depending on lighting and distance to subject. If you take 3 shots of a subject and focus them all separately, you will have 3 differently focused shots... so it's also random AF (different meaning for AF this time).

1.8k could be spent on some interesting lenses. I'd get the L fisheye just for fun and maybe a 600ex-rt. Not sure if 1.8k is enough for those...

I would buy a gift for my wife, so she wouldn't not give me hard time when I'm ready for 600mm f4 ::)

Does it really work that way for you? No matter what I buy for my wife, she will be pissed if I get another lens.

Lighting / Re: Looking for a macro ring light for 100mm L
« on: January 19, 2014, 08:06:49 AM »
Ring flashes produce unwanted results. With the 100L + tubes I usually just use a normal flash. Brackets and such help a lot too, but in most cases you can take pics without them and still beat the ring flash options. That being said, my best macro shots are the ones where I used my own DIY setup: 430 EX II flash, TTL cord, 2 L-shaped metal pieces, ... Even when attached to an "arm", the 430 flash is still not too heavy to annoy me to death.

EOS Bodies - For Stills / Re: Driving myself crazy, need help!

I'd actually advise you to go even lower than that to start with. Go for one of the entry level cameras, or a mid-high end quality mirrorless ILC. And then buy a couple of cheap primes. For Canon the 40mm f/2.8, 50mm f/1.8 are quite cheap and reasonably good quality, especially the 40mm. Not sure what the Nikon decent & cheap prime(s) are.

Over the years I've learned that the easiest way to kill a hobby is to start with crap equipment. Instead of climbing the ladder from cheap bodies and lenses to the good stuff, it makes more sense to get the best suitable stuff one can afford straight away. Especially with lenses there isn't even a huge risk of losing the money if the hobby doesn't last.

That being said, I started my DSLR hobby with a damn Rebel and I bought a better body after 2 months. Should have never bought the Rebel. I don't even like the photos it produced even though it was paired with decent glass. Now I have mediocre quality photos of my first daughter's first months.... Boring DOF and low + grainy image quality already at ISO 800.

And as a final note, my budget basically is enough for either the 70D or D7100, so roughly $1150 or so. Since this is my first camera, is going with either the 70D or D7100 the smart choice, or should I honestly just save up for the Full Frame, like the D600 which is only $1500 currently? My brain hurts guys, help!

How long do you need in order to save the extra cash? Honestly, if you want quality and the lowest possible price, I would look at the Sigma 35mm + a 6D or the comparable Nikon. The types of photography you mentioned all ask for FF. Crop has no benefits there.

Having 1 value for a lens does not fix much.

I didn't read the patent so I don't know for sure but, does it say it only uses one value?  Or does it say multiple values are not possible?

1 value would only be sufficient for "on-the fly/in real time" correction applied to every shot using Phase-AF.

Since this is not feasible [Phase-AF followed by contrast-AF, calculation and application of correction factor  for each single shot] there must be a specific "AF-calibration procedure" to be started from the menu or possibly autmatically, every time a lens is mounted on a body that has not been calibrated for that body yet. And similar to current AFMA, there must be a storage matrix for each specific lens, with multiple correction factors for
  • a number of different subject distances at
  • a number of different f-stop settings in all lenses that are not fully parfocal [= majority of all Canon lenses].
  • and in case of a zoom lens, for a number of different focal lengths

Most of it is available on Sigma lenses via the USB dock. The f-stop thing is interesting, but it could be automatic at least for Canon lenses to make up for focus shift.

The USB dock is useless. For the 35mm lens you, for example, can only give 1 value for everything that is further than 70 cm away? Correct? At least that is what I was told the other day when I was about to buy a dock. So sensible settings are only available, if you shoot nearby subjects. And for that, I'm fine with my +3. The focus gets messed up when people stand 5 m away from me, whereas for 2 m the +3 still works nicely.

So instead of trying to fix the AF issues, they come up with a ridiculous AFMA solution? At least for me, the AF accuracy and AFMA value depend heavily on the distance to the subject and even the lighting can affect results. Having 1 value for a lens does not fix much. Besides, a slicing golfer can surely aim off fairway at the tee, but that is a lame way to deal with the slice. A better solution is to fix the slice.
