my sigma doesn't have any CA problem, and neither did photozone's or lentip's. was that " longitudinal chromatic aberration" or " lateral chromatic aberration" that was bothering you? either way, it shouldn't be.

and the answer to your question is no, sorry. you'll have to find a RAW solution.

normally i'd second what's been said, but not today.
so you are comparing a real camera with an imaginary camera, then saying that you would never replace your mk4 for this imaginary camera. i thought this was entitled "7dmk2 v 1d4"?

 now that i think about it, if anyone out there wants to replace their existing camera with an imaginary camera, please get in touch with me. i'll gladly swap you an imaginary camera for your real camera. PM me!  ;D

That looks like a no. I should have my hands on something this week, and I'll try and post a few words about it when i come to some conclusions. Perhaps i'll have something so say about that feisol ballhead with the nasty little plastic knobs too. there is little on the net for either of these items, so maybe people could benefit from a bit more info. Since i have little exp with these things i'll mostly be comparing it to my manfrotto 055xprob, 486 ballhead. later.

Lighting / Re: Flash that will endure over 2000 continuous shots?

I see no reason you should spend a load of money on lighting for photographing books. i recommend a tripod, and a couple lamps with the same bulb. hell, with a tripod you don't even need lights, you could do it in the dark, but i don't recommend that method !

Lenses / Re: Zeiss 15 vs Canon 14

i'd love a zeiss 15mm but decided to slum it with a samyang 14mm. It gets it done just fine, better(sharper) than my 16-35mmv2 was. The build seems okay, but Roger at lensrentals says internally it's not so great, but as he points out, one could buy new replacement for the cost of a typical repair to something like the canon 14mml.

EOS Bodies - For Stills / Re: Center and Spot Focusing
« on: May 29, 2013, 07:47:44 PM »
I've used cameras for many years, its only recently that electronics has advanced enough to allow the use of multiple focus points.  Its a convenience feature that lets the camera track a moving subject, or focus on a off center subject. 
If you don't think you will use the other focus points, you might be better off to wait and see what a new model brings to the table.
One of the truly excellent features is AFMA, I'd avoid a camera without it.  It allows you to fine tune the autofocus of your lens to your camera body.  If you have a wide aperture lens, that can make a huge difference.
Don't go out and invest $$$$ in a expensive wide aperture f/1.4 or f/1.2 lens unless your camera has AFMA.
what he said.

Technical Support / Re: Going medium format for studio work?
« on: May 27, 2013, 08:15:53 PM »
I have no hands on exp with any medium format digital stuff, but a fair bit of medium/large format film. Even if it wasn't for the steep entry fees to get into MF digital i would suggest renting some stuff. The expense of renting some stuff will be very small compared to what you are likely going to be getting into with MF gear. Many of the things we take for granted with canon/nikon etc smaller sensor stuff just isn't there for medium format.

you guys seem to be confirming what i was thinking. that is that when your gear gets to a certain size/weight you really need a gimbal mount regardless of what strengths your head/tripod might have.

Does anyone here have any exp with wooden tripods? namely something from Berlebach. I know they are heavier than most other stuff, but it's not enough of a difference to matter to me. in total my other gear weights so much more a couple lbs here or there makes no difference, esp with a tripod.

the latest and greatest is in the latest cameras, regardless of their market segment, and, what wickidwombat said.

71 the 5D Mark III the metering bias is too high.

I wonder how all the people clamoring for the 5DIII to have AF-point linked spot metering would feel about that observation?   ;)

To everyone who wanted AF linked spot metering, surprise, you have it!

i didn't find much on the net as far as reviews of the feisol ballheads, but i did come across lots of praise for their tripods. Alas, my tripod is a manfrotto 055xprob, but i actually prefer flip locks so it works out for me. I do like how Feisol gives fairly detailed dimensions or their heads. If Induro had i wouldn't have fooled with that model i ordered. when i slapped it on my tripod it didn't even come close to covering the base plate. this cb-50 fits very well.   

 I had a feeling you might respond and a feeling you might say that. Damn, that RRS piece seems to get love from everyone, it must be fantastic. perhaps with this feisol (a 160$ unit) i'm just putting more force into it than is reasonable. While I'm very far from Hercules i was carrying around 10ft sections of telephone poles yesterday. Again, it doesn't have any problem supporting my gear anywhere i put it, until i start looking for it's limits by adding my own force. i should probably just not do that. reminds me of that old joke when at the end the doctor tells the patient not to do that.
thanks neuro!

nice! marc sure is something.

I have a question for you. one i might not want to know the answer to, but I'm asking anyway. Say you mounted  you camera plus 300mm f2.8 or so and then tilted it over into the portrait area of the ballhead a bit. not down on the stop, just off kilter a bit, maybe 45 degrees or so then locked it down. If you put you hand on the top of the lens, and put some force into it is it pretty easy to overcome the ballhead lock and get it to move? You see i'm in the process of replacing my manfrotto 486 with a stronger AS style model. that induro model i first looked at was underwhelming. Currently I'm fiddling with a feisol cb-50. It has no problem holding my 300mm in any position(it's got a 50mm ballhead so i would expect it to do pretty well), and really other than the nasty little hard plastic knobs, i don't have complaints, but it is easy for me to overpower it. But i have limited exp with these things. perhaps i'm expecting too much.
