Software & Accessories / Screen protector question
« on: May 19, 2013, 03:27:00 PM »
The question is about the use screen protectors on DSLR's.  I'm aware this issue has been discussed but I'll kindly ask for a few updated comments.  I reviewed a variety of threads on this issue last year when I ordered my 5D III and I recall there were a variety of views.   

Do you heavy, serious DSLR users use an after market screen protector of any type?  Film, glass or other type?   

I had one of the Giottos Schott glass covers but was not durable.  It cracked when there was no evident stress on the screen.  Or not much.  The $40 cost of another one is not an issue but I wonder if this type gadget is marketed mostly to use newbies who don't know any better.    I'll appreciate you comments...........

Software & Accessories / BlackRapid & Kirk clamp hook-up
« on: February 16, 2013, 07:56:06 AM »
I'm aware the technique of attaching the BlackRapid FastnR set screw to a 1" Kirk QRC clamp (or similar) has been discussed over the past few months and some of you have posted pictures (Neuro posted a few).   I want to switch to a BR strap and I want some type of fast disconnect.  However, I have two question:

1) By hanging your kit off the Kirk or similar AS style clamp, you are apparently totally trusting the clamp to stay fully tight - and therefore not to have any loosening of the the set screw that tightens the clamp.  I'm trying to get comfortable with that but feel I would be constantly checking the set screw to be sure it's still tight.  Please tell me this is not a concern and why...!

2) Assuming one buys in to the everlasting torque of the set screw as discussed above, why wouldn't it be better to use the 1.75" clamp as opposed to the 1"?  The cost and the weight difference is minor - but the 'holding capacity' of the 1.75" should be much stronger.  Is there any technical reason not to use the larger clamp?

I hope someone can convince me constant jostling and vibration would not loosen the screw that holds my expensive toys, and thus allow gravity to give me a free lesson in physics.   Thanks..........    Tex in Luanda, Angola

Lighting / Help w/ fill flash & slow sync
« on: September 20, 2012, 03:19:08 PM »
I have a 5D MK III and a 430 EX II. I almost never use the flash with this gear,  but with my smaller cameras (and built in pop up flash) I frequently use fill flash during the day and occasional slow sync for night pics. 

I occasionally would like to use fill flash or slow sync flash with the MK III and 430 but it appears the only way is to truely go fully manual.  Any tips or guidelines on how to do either without needing a light meter etc. or simply guessing???    I don't find the 430 user guide much help.  Thanks..........

Software & Accessories / Need to PDF a set of photos
« on: August 12, 2012, 09:29:33 AM »
I am a PC user and would like to occasionally generate a single PDF doc of 5-10, or more photos  Are there programs embedded in windows 7 or are 3rd party programs better.

Software & Accessories / MK III screen protectors
« on: May 30, 2012, 08:47:44 AM »
This topic was discussed somewhat a couple of months ago but I wanted to ask more specifically if the conventional wisdom suggests a film protector (XO Skins type) or a hard protector (Vello glass type) is best.  Or nothing at all??  I recall Mt. Spokane said there is already a protective cover there the could be changed.  My bias is to apply some type cover anyway - either film or one of the thin glass ones.  I'll appreciate your comments.

Software & Accessories / Travel tripod -- quick connector systems???
« on: April 12, 2012, 02:40:14 PM »
Based on a variety of learned opinions from this site, I'm setting aside the notion of buying a Benro Travel Angel and will buy a Gitzo Traveler 1542T.  I have, and use extensively a Manfrotto monopod with their monopod head & quick connector.  For the 1542 I plan to buy a Manfrotto 054 Magnesium head with the Q2 quick release  (QR)plate.   It's the same model 200pl plate used on my monopod.  My obvious goal is to uses the same QR system on the monpod and tripod.

I'm seeking comments on the merits of the Manfrotto QR 2 system - which is their their smaller plate.  They also make a larger QR system but i prefer to use the QR 2 if it appears sound.  Manfrotto's site does not give comparative values of the different QR systems.

I'll soon be bolting more expensive toys on top of these kits so I want to have a good feel that the QR system is not a weak link.  The tripod is rated at 17lbs and the  054 head ad 22lbs. In the near future I'll be using 5d MK3 with largest lens likely being a 70-300 L series.

Software & Accessories / Best photog backpack??
« on: March 21, 2012, 03:09:49 PM »
I'll be purchasing a new kit soon.  Mk II  (yea, I know but $2000 is enough for me) with some L series glass.  E.g. 24-105, 70-300 and quite a few accessories.  What is the conventioinal wisdom on the best backpack???  I would want something that has a very flexible layout.  Very good quality, very protective, etc.   We all know the Case Logic brand but what is the best in class for carrying and protecting our toys?

Lenses / No 2X extender for 70-300mm L Series
« on: March 19, 2012, 07:58:50 AM »
I just found out that the Canon externders (models II or III) will work with most ranges of zooms but not the 70-300mm L series.  I assume this must be due to it's "trombone" design or some issue related to it's compace size.  Can someone elaborate????   Thanks.
