Lenses / 24-70 f4 IS macro performance
« on: June 25, 2014, 05:41:11 AM »
I haven't really managed to find a reliable assessment of the 24-70 f4 IS macro performance.
I was looking into some of the cheaper options such as the 50mm 2.5 macro but it occurred to me that the 24-70 might be good enough for my macro hobby while also being very useful to me professionally as a replacement for my 24-105 (also, there is a 250$ cashback on the 24-70 in my country)
Anyone care to chime in with their experien, the ? Is the macro function on the 24-70 comparable to a dedicated macro lens? (I am aware of the very close focusing distance required to achieve x 0.7)
EDIT: After the mail-in rebate in DK, the 24-70 ends up at around 1100$

Speedlites, Printers, Accessories / Third-pary Grip. Safe?
« on: April 29, 2014, 09:17:35 AM »
Hi
I have been doing alot of lengthy outdoor video shoots on my 5D lately. Even without ML raw, this can cause quite the power drain, so I am looking at different budget options for extended shooting. So far I am using extra cells and a car charger, but it is still not enough.
Rather than just buying more cells, I am thinking about getting a grip for the option of using normal AA cells in case of emergency. (If you badly need more charge than expected, you can send someone to pick up a load of AA's at a gas-station)
So, my question is if anyone here has any good/bad experience with the really cheap third-party no-name grips from ebay like this one: http://www.ebay.com/itm/331137824745?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
 
I know quality will not be the same as an original grip (possibly worse than the more expensive third-party options) but do you think its safe?
If it's DOA or stops working after a while, that's fine. Ebay buyer protection actually works, and I have always gotten full refunds in those cases. My only concern is if it could cause damage to my camera even though my intuition tells me that this would depend on the cells I use rather than the grip?


Nb. No need to preach about using cheap stuff on paid gigs. I am doing what I can with what I've got (rigging a DSLR for real video production is expensive) and this is meant to be a backup solution rather than something I will rely on regularly.

Speedlites, Printers, Accessories / 430 EX II vs Metz 52 AF-1
« on: August 27, 2013, 01:49:28 PM »
So, I am starting to get a bit into event-photography (a few low-key weddings and some conferences) and seeing as I don't think my Olympus Fl36r is safe to put on my 5D3 in terms of voltages (and also wouldn't be a good idea for various other reasons) I need a bit of advice.
I have been using the 600EX-RT on a few paid jobs, but it is a bit out of my price-range for now, and I am not sure that I really need it at all.


For now I am looking at the 430 EX II and the Metz 52 AF-1 seeing as they are priced almost identically in my region.  I understand that the Canon might give me more reliability and compatibility whereas the Metz will give me more power and functionality. Still, there are a few things I didn't manage to figure out using google, so I am looking for some who can enlighten me or even someone who has used both.
What are the key differences (apart from USB port and the other things mentioned)
Can the Metz be controlled in-camera like the Canon?
Am I right in assuming that neither model will support all Focus-points for AF-Assist?
[size=78%]Is the touch-screen on the Metz as ennoying as it looks? :)[/size]

Software & Accessories / Lightroom 4 performance
« on: April 24, 2013, 06:41:34 AM »
(If a similar thread evaded my search, please point it out ad I will move this post)
Like so many others here, I am learning more and more about Lightroom as I grow as a photographer. I love the ability to both manage my vastly growing collection plus do most of the PP that I need on a weekly basis.
As I upgraded to bigger file sizes (Full raw from 5Dmk3) as well as started using more advanced (and possibly much heavier) PP in Lightroom I am however experiencing some MASSIVE performance issues.

Granted, Lr was never superfast, but I never took the endless Lr complaints seriously until recently. Sometimes I will wait through a 10sec "lag-spike" not sure if Lr is actually working or just taking  a deserved break. The reason that I am writing this lengthy post is that I a very curious to find out if this is a Lr issue or if something is off with my system.
A week ago, someone (my new nemesis it would appear) sat on my just month old Thinkpad W530 and whereas no obvious damage happened I can't help but worry. During the last week, I have seen the aforementioned 10sec spikes for the first time, but I have also been playing with some HEAVY PP (spamming multiple dense presets, experimenting with artistic ideas)
Being a philosophy major, I am always cautious to mistake causality with coincidence and seeing as the lag-spikes are irregular, for now, I don't have a problem that can be replicated, should I choose to send in my laptop for good measure.
So I guess I am interested to hear what kind of performance issues you guys might have had with Lr on a reasonable fast machine and how you solved them.
Also, I was wondering if some Lr-based benchmark exists (similar to premiere pro, where some users have created a benchmark-project that you can download and time to compare your system speed to others)

My machine is an i7 3720QM 2.6 - 32GB DDR3 - 2x 256GB SATA6 SSD - quadro K2000M 2GB Running win pro x64 and Lr 4.4.
I am using the built-in x-rite color calibrator

I have read that one might see a performance increase from making a new catalog per project. My current catalog is around 40.000 pics (around half offline) How big a factor is this?
I am using custom camera calibration (using the VSCO film-ones quite often) plus pulling many if not all sliders (learning by doing) Could this in itself be enough to cause the spikes? (I use spot tools VERY rarely, but I crop alot)
My windows is pretty well kept the pc is rather new and I tune it once in a while (sfc /scannow etc)
When I export/render, the cpu is very busy, but when I get the spikes and unresponsive behavior in Lr, the cpu is often fairly idle.. so what gives?
Is there something I am missing?

edit: seeing as I have 2 separate SSD's in my machine, any advice on optimal placement of folders? (ACR cache (set to 20GB), catalog, preview files (I always generate 1:1) and actual photos (I keep my projects on internal SSD while working on them)
Edit2: Tried replacing my preference-file as suggested in other forums - no change.
Disabling the "detail" pane however, seems to have an enormous effect on performance. Does anyone know of a way to disable a pane globally ?
(In the future I will deal with sharpness and noise just before exporting, but for all my pics that already have these changes, this of course is not an option)

I am about to "invest" in a new smartphone, and one of only reasons for going with a smartphone instead of a "phone-phone" is the aspect of using it to control my 5D mk3.
I am interested in both tethered and wireless options, but I am only finding sparse information pertaining to the options available to the different platforms ie. IOS, Android and windows phone 8
Any advice?
I am especially interested in finding out more about windows phone capabilities as I really like the Nokia Lumia (when actually using it as a phone) and find the apple to expensive :)
In the end, Android may be the way to go...

Third Party Manufacturers / Hoya uv filters - product differentiation
« on: March 10, 2013, 12:11:26 PM »
After reading this test:
http://www.lenstip.com/113.4-article-UV_filters_test_Description_of_the_results_and_summary.html
I have decided to pick up some hoya UV filters for myself ( and a few friends using crap filters)
The "Hoya 72 mm Pro1 Digital MC UV-0" seems nice, but I can't really figure out the meaning/significance of the "UV-0" designation.
My question is essentially if these two auctions are the same as they seem to be the best deals I can find:

EOS Bodies - For Stills / How sharp should pics from 5D3 +24-105 be?
« on: March 03, 2013, 05:45:55 AM »
Sorry for posting this again, but I figured that this is the right place for the question rather than in "technical support".
I finally took the plunge and got a 5Dmk3 kit and suffice to say, I am LOVING it. The handling is amazing (on a side note, on my second day of ownership, I learned the hard way that there is a difference between a splash of water, a bit of dust and then the cursed sand of the desert wind  alas, a grain of sand got under the focusing ring of the 24-105 which now makes a grinding sound that even gets picked up by an off-camera mic  )Anyways, apart from this unfortunate occurrence, I need to make sure that I got an ok copy today, seeing as the 14 days of "no questions asked in case of a malfunction-return policy" ends tomorrow. I am no pixel peeper, and I am not the type to buy a box of lenses and only keep the best one. That said, given the substantial size of this investment (for me at least) I'd like to make sure that neither camera nor lens has any obvious faults.So, if anyone would lend me they eyes, it would be greatly appreciated.The "test" shots are with the proper test settings I think (neutral, no NR, tripod, tethered, no monkey business and straight out-of-camera)

Software & Accessories / Close-up filters: Size/Performance
« on: January 21, 2013, 04:08:16 PM »
I've been playing around with Extension tubes and Close-up filters for a few years and though I know that a proper Macro lens is the way to go, this is besides the point of the current question:
Is there any theoretical/practical performance to be gained by using a bigger close-up filter with a step up ring rather than the "native" size of the lens?
