Third Party Manufacturers / Re: 10 Signs You're a Photo Geek
« on: September 20, 2013, 10:54:19 AM »
You might be a photo geek if...

Your email is "photogeekX@soandso.com"

Flew that flag proudly until it was time to get a more professional communique.

excellent position to take Chas, i really wasn't trying to let this thread digress into questioning the validity of other members photography. i really only wanted to offer my opinion from my direct experience.

i hope it proves helpful and whatever you decide, you will certainly have an exciting purchase upcoming!

Neither of you apparantly understand that the shooting aperture has nothing to do with the focus accuracy.

f4 might get everything reasonably sharp at 17mm on 135mm / leica / minature format DSLR's, but won't get you far anywhere else unless eveything in your scene is on the same focus plane.

The advice is useless, tosh.  My biggest gripe is that somebody would actually read it and try it and miss out on important shots.  Might as well have said get a lens with hyperfocal scales and shooting everything at f11.  It's got about as much to do with how AF works.  Jaysus.

Unless of course you meant that we should all buy lenses no faster than f4 so we can give our AF systems a chance for point and recompose.  Or try just not using it

I stand by it lads.

i dont disagree with your technical assessment of either of your posts....but none of that has anything to do with what Neuro and I are suggesting to the OP.

to be clear, if AF accuracy is the desired result coupled with the focus and recompose technique then what i am advising to the OP is buying the 5D3 would be a better option for him using his existing lens lineup and using the improved responsiveness of the 5D3's outer points when composing RATHER than buying 2.8 zooms and continuing to do focus and recompose.

yes, buying 2.8 zooms offers better AF on the 5D2...but any accuracy gained is wasted on the focus and recompose technique as the very simple physics of the technique circumvent the accuracy of the original focus acquisition...unless of course your are shooting at F4 and above with the extra depth of field that would compensate for the discrepancies introduced with the recomposition. at this point....a wiser recommendation would to be just buy the 5D3 to take advantage of better, more accurate focus points outside of the center point and ditch focus and recompose.

this is sound advice...which does not ignore your completely valid points about how AF systems work coupled with different lenses capable of different maximum apertures. your posts do ignore however the very real problems the focus and recompose technique introduces to focus accuracy....especially at apertures greater than F4. the OP should be made aware of this to help inform him of his decision.

i appreciate your enthusiastic points...but you are arguing something that 1. i dont disagree with and 2. doesnt have anything to do with the actual point that i am discussing.

  Use of center point only and recompose on the 5d2 using F4 and above would most likely yield acceptable results in most circumstances. Try that at F2.8 and wider and your results will plummet.


Sorry, but this is absolute tosh.  You clearly don't understand the concept of non-stop down lenses with aperture coupled metering, which have been widely used since the 1960's.


You apparently don't understand, or are ignoring, the reasons Why Focus-Recompose Sucks, to which agierke was alluding.

Thank you neuro, that was exactly what I was talking about.

And Paul13Walnut5, I've come to expect better from you than to rush judgement and toss out degradations like that. I do understand very well what you detailed in your post. But that doesn't circumvent the simple physics of shallow depths of field and the problems one encounters with the focus and recompose technique. You can get away with focus and recompose at F4 on most focal lengths but wider apertures than that it becomes a tremendous problem.

From Agierke: "For my own experience though, the AF system on the 5D3 brought added functionality to ALL my lenses to the point that it was like having a whole new set of lenses. It was that much better than my 5D2."

This is REALLY the way I want to go. It's taken me a while to build my lens stable and I like it pretty much the way it is. If the body swap would breathe new life into them, that would be my preference.

i think you will find that it will. its a change in approach but once you get the hang of it its well worth it. moving forward after that you can be confident that you will be getting the most out of any new lens purchases whether they be 2.8 zooms or fast primes.

if you feel strongly that focus point freedom and reliability is what you personally need for growth then the 5D3 is for you. staying with the 5D2 and going with 2.8 zooms will likely exacerbate any focus issues you may already be experiencing with the focus and recompose technique.   

141
It also would depend greatly on what area of the auto focus system was being used and under what conditions. It's not such a cut and dry situation.

Use of center point only and recompose on the 5d2 using F4 and above would most likely yield acceptable results in most circumstances. Try that at F2.8 and wider and your results will plummet.

I wanted more creative freedom out of my auto focus system plus added reliability at wide open apertures. Couple that with my transition to the use of fast primes and the 5D2 just didn't cut it. The 5D3 was a necessity for me and something I had been pining for since I purchased the 5Dc upon its release.

As a pro I needed predictable and dependable results in some of the toughest conditions. I got by with the 5D2 for a while only because I couldn't afford a 1D series camera, but there were far too many times the gear couldn't perform reliably for the way I wanted to shoot. The 5D3 changed that and I can now shoot with much more confidence.

As a non pro, you may or may not find a benefit to the 5D3s focusing system. You may see a more immediate benefit to a 2.8 zoom. Heck, I work with some pros who still won't consider shooting wider than F5.6 and have no interest in the 5D3s AF system. In the end it's to each his own.

For my own experience though, the AF system on the 5D3 brought added functionality to ALL my lenses to the point that it was like having a whole new set of lenses. It was that much better than my 5D2.

Ohh yeah it is from canon and legit. Not from a offsite. They screwed up a repair 4 times over and ruined a few small jobs and an event.

ah i see. what luck! though it sounds like you had to earn it with some grief.

sry for being such a downer earlier...i'd rather play devil's advocate to help someone avoid getting screwed though. there has always been so much scam in the photo equipment business that when it sounds too good to be true then it most certainly is.

shame you couldn't pull the trigger on everything though. at those prices you could have sold a few of the peices and probably gotten what you wanted for essentially free.

Lighting / Re: Finally getting some Eneloops, but will my old charger work?

If you have rechargeable batteries, this charger is a no brainer.

If you have eneloops, how is this ~$60 charger better than the ~$6 charger from Sanyo?

depends on your usage i guess if you would see a difference in performance over time.

i have sets of powerex batteries that i killed over time due to the amount of usage they got. even rechargeables dont last forever. the maha charger i have has multiple charge modes that allow for quick charge, slow charge (better for long term health of the batteries), and a refresh charge that can actually improve the performance of older sluggish batteries. a standard charger may not offer these extra features.

the 60.00 higher end chargers can increase the life and performance of your batteries. they can prevent you from having to spend on additional batteries over time at a clip of 30-40.00 per set. my charger has saved me a ton of money.

but again...it depends on your usage. i use my batteries heavily and have seen the difference of charging modes 1st hand.

I had an Energiser charger and had been using it to charge my Eneloop XX batteries.  It all appeared to me to work well but I purchased the charger below just because I read good things about it online.

http://www.mahaenergy.com/mh-c9000/

Well what a difference, using the C9000 improved capacity lost, my batteries last ~20% longer now.  The eneloop XX's were not very old which leads me to believe the Energiser charger was robbing them of capacity.

If you have rechargeable batteries, this charger is a no brainer. 

+1 to this. i have something similar that allows for more control over the charging process and it increases the life and performance of my rechargeable batteries. its worth it to spend a couple extra bucks now as it will save you alot of money in the long term. a high end charger can even rescue a seemingly dead set of batteries.

dont cheap out on a charger.

The OP stated these are Canon refurbs, so yes it should be ensured he's dealing with them or an authorized reseller...

Yes I saw that, but if you go to the canon refurb site they list these items significantly higher than what the OP is stating. So I am confused as to the source of these items. They don't appear to be refurbs direct from canon, so if that's the case where are they coming from and how is it that they can be claimed as canon refurbs?

Those prices are so low that something really feels off to me. It could be legit but if I were in that same position I would be asking a ton more questions before I even started considering which combo I would want

umm....no one else thinks this sounds too good to be true? the scam factor on this is raising major red flags for me. i would hate for you to drop significant money on what you feel is a great deal only to find out you got taken and are unable to recover your money.

please tell me this is an individual you know who is unloading his gear on the cheap.

Lighting / Re: Lighting large groups, help needed!
« on: September 13, 2013, 10:50:50 AM »
lighting is simple, 2 45" umbrellas to left and right. get them positioned above the subjects heads so shadows fall behind them. speedlights or strobes doesnt matter so long as you understand your limitations on power output and how that will affect your optimal exposure settings. dont overthink this...you dont have the time to mess about.

the real problem will be 1. finding space to accommodate a group of 30 2. organizing that group of 30 so they aren't a mess piled on top of each other and (steps or chairs will come in handy) 3. maintaining enough depth of feild (this will greatly depend on the maximum power output your lights are capable of).

i would bring a step ladder if i were you.

no one can accurately tell you what iso and aperture you should shoot at unless they were familiar with each actual location. lighting varies greatly from location to location and will even vary greatly within each location.

the only answer is shoot at the lowest possible iso at whatever aperture you find effective that will provide good exposure for the chosen shutterspeed. thats it. you got to use your noodle for this. anyone telling you specific isos and apertures is simply taking a stab in the dark (forgive the pun) and if you follow advice like that you probably will not end up with optimal results.

i can tell you this, if you don't have some sort of lighting solution option you are likely to run into scenarios that you just cannot shoot. bars and restaurants have the potential to be brutally dark.

Canon refurbs has these listed as much higher in price. The 85mm 1.2 is listed as @ 1800.00 refurbed.

These prices are very suspicious for working order refurbed high end lenses. Are you certain the source is legitimate?

the 10 stop filter would be the only one i'd be interested in for a lens like the 17mm TSE. most everything else can be done in post.

it is nice Lee is developing stuff for this lens....i just wish they would do a better job at providing stock on a consistent basis
