Videography Technique / How can I tell if my microphone is working?
« on: September 02, 2014, 02:54:47 PM »
Hi guys,

I've been asked to video a friend's wedding in a few weeks, so I have purchased a cheap stereo mic from Ebay. It's a SG-108. I think it doesn't work, as the on switch is a bit iffy, but how can I tell on a 5d iii if the mic is working and the sound isn't coming from the in-camera mic?  I have recorded some footage with the mic in and removed it mid way through and I noticed no difference in sound quality. Any thoughts?

Many thanks,

Grant  :)

Photography Technique / Help: lightning photography?
« on: July 18, 2014, 03:46:30 AM »
Hi guys,
We had a great storm last night with loads of lightning. I tried to take some shots but nothing came out.

I have a 7d and a 5diii at my disposal along with a canon 24-70, 70-200 is I and a tammy 150-600. I was using the 7d and 24-70 last night.

Could anyone please let me know what sort of settings would be best on which camera and which lens, as we are scheduled for more lightning tonight.

Huge thanks in advance,

Grant :)

EOS Bodies / 5DIII CF vs SD slot performance?
« on: July 10, 2014, 10:36:00 AM »
Hi guys,

I've recently purchased a 5DIII, to get some practice in before my holiday as the 7D2 won't be ready in time.  I was wondering what the performance difference was when shooting CF vs SD, what with the dual slots.

I've got some OK speed (266x and 600x) CF cards and some OK speed SD cards (30mb/s and 45mb/s).  My reason for asking is  that I have a raft of the SD cards, accrued over the last few years for shooting twin 60D, and not many CFs.  I was wondering if when on safari I ran out of CF space, I could switch to SD, but how much fps would I loose?

I'll be mainly using the 5DIII for lanscape and closeup animals, but might want to set it to rapid fire, or even video if anything interesting happens.

Many thanks,


Lenses / Filter for Tamron 150-600?
« on: June 11, 2014, 06:11:35 AM »
Hi guys,

I've done it.  Placed my order for the mighty 150-600 last night, hopefully it should arrive before September.

There aren't many (good) 95mm filters arround and all are pretty expensive, I know there are cheaper non-branded, but I want a good quality filter for wildlife shots.  So, what one would you recommend?

So far I've found these in the £75-100 range:
- Sigma EX DG Ultra Violet (UV) Filter - Super Multi-Coated
- B+W F-Pro SC 010 Brass Clear UV 70179
- Marumi DHG
- Hama HTMC Coated UV Filter 390 (O-Haze)
- Hoya UV(O)

Many thanks in advance,

Grant  :)


I'm thinking of going for rechargeable batteries as it's good for the trees and bunnies, and in the longer term, my wallet.

There's been quite a bit of talk about Sanyo Eneloop batteries bering the way forward, but I'm not sure which ones to get.

The options I have found are 1900mAh, 2450mAh and 2550mAh.

Whilst I am tempted to go for the higher power ones, albeit at a higher cost, I was wondering if I could get away with the standard 1900mAh Eneloops?

My flash is used mainly for wedding photography during the evenings, so I want it to last, and I want the rechargables to last for abot as long as the Duracel normal batteries I use.

Any advice or imparting of experience would be most appreciated.

Many thanks,

Grant  :)

Landscape / Astrophotography - which camera?
« on: April 11, 2014, 06:09:29 AM »
Hi guys,

the ISS is flying over my house tonight and I really would like to get a shot or two of it.  I have at my disposal a 5D2 and a 7D, a 70-200 2.8 IS2 and a tripod.

Which of the cameras should I use?  Is it best to go for IQ/ISO over reach?

Many thanks,

Grant  :)

EOS Bodies / 1D IV or 5D III or other - Wildlife photos
« on: March 10, 2014, 10:07:52 AM »
Hi guys,

I appreciate that this is a bit early, and there is still a chance the mythical 7DII might appear, but I'm starting to draw up a list of camera gear for my safari in September.

Last time we took a 7D, 2x60D and a 40D, coupled to a 100-400, 70-200 2.8II and a 24-70 each, giving us wide and reach and no need to change lenses.

We have recently purchased a 5D2, which was at a bargain price, so that is on the cards for taking this time, thogh is a bit slow for wildlife.  We are looking to upgade some the kit this time (at least the 40D), and within the budget limit of about £1800, the following cameras fall out with good fps and at least good(ish) IQ:
  • 1D IV
    5D III
    7D (mark 1)

I know the 1DX is a killer, having played with one, but it is way unaffordable, and I have no intention to hire, as I can always sell the camera when get back to the UK (it's what we do with the Canon 100-400), so that it effectvely becomes a "free" hire.

So the question is, with a budget of £1800, what would be the best camera to go for, assumning tht the 7Dii doesn't appear, or should I go for e.g. 2 more 7D?

Huge thanks in advance,

Grant  :)

Lighting / Help: Yongnuo 622C and multi camera configuration
« on: March 03, 2014, 01:51:06 PM »

My wife and I do a bit of wedding photography, and have been using remote flashes for a while for some great shots.  She shoots 7D and I shoot a 5D II.  We use the Yongnuo 622C wireless Tx/Rx boxes, one on the camera and one per remote flash.  We use a mixture of Canon 430 EXII and Yongnuo YN-565 EX on each YN 622C.

Everything works fine.  Well, it did until we tried to be clever.  Initially only my wife had the 622C on her 7D and only she controlled the remote flashes.  I just ran with a 580 EX II on my 5D II and had no remote flash control.  I know that the 580 EXII can be used as a commander, but we bought it after the remote units and use it as an on-camera flash unit.

However, last week we tried to get clever.  We both ran with a 622C on our cameras, so that both of us could use the remote lash units, and this is where problems arose.  On taking a shot, one would trigger the other's on-camera flash as well.  Not ideal.

I have tried to read the "chinglish" that the instructions are written in, and I thought I understood them, but I was wrong.  I thought that I could set the flash remotes to work on 2 channels so that independent cameras could trigger them, but but I can't seem to get it to work.  :(

Is there any way that we can set up a bank of remote flashes, each with a YN-622C unit attached so that they can be independently fired by two cameras, both with a YN-622C unit and a Canon 430-EX II on them?

Please help  :)

PowerShot Cameras / New Powershot D30 - specs
« on: February 12, 2014, 05:33:43 AM »
from B&H...


Apart from being able to dive deeper and few more "kids modes", this looks like same as the D20.  Same fps, same ISO, same lens, same HD video, same 12mp sensor, same DIGIC 4 processor.

Shame. I was hoping for something like the Olypus TG-2 or Panasonic DMC-FT5, e.g. more fps, higher ISO and a faster lens  :(

About as much of an advancement as the "White EOS" of last year   >:(

EOS Bodies - For Stills / Aftermarket upgrading of cameras?
« on: January 02, 2014, 09:15:49 AM »
Hi all,

bit of a random question, but is anyone aware of any companies that can upgrade cameras?  I drive a TDI Golf, and recently bought a "boost box" that gives it more power / better fuel economy (depending how heavy my right foot is), and it got me thinking, could I do the same (or similar) for my old 40D?

I am aware of Magic Lantern and the great stuff they do, but for example, a memory upgrade could give me a bigger buffer for a longer burst or maybe a Digic 4 could give me higher FPS than the Digic 3.

I appreciate that costs might be a tad on the prohibitive side of things, but I was wondering how easy it might be (or if at all possible)?

Happy new year by the way!  :)



Canon General / Buying "dodgy" American Canon camera gear?
« on: November 06, 2013, 11:10:27 AM »
Ok, American camera gear isn't dodgy, it's all totally ligitimate, BUT it's a hell of a lot cheaper than it is in the UK (less that $ for £ in many cases)!

My question is, now that I have got your attention, "Is there any risk of buying Canon cameras and lenses in America when I live in England?"

Basically, I am planning to be in Vegas in February (I know, prices in Vegas are expensive, but B&H / Adorama, etc. ship to hotel rooms) and I am planning to acquire a couple of lenses and a body - camera body, not the usual Vegas type of "body"  ;)

Your odd voltage and her majesty's customs and excise issues aside, are there any issues with using "American" gear in the UK, such as waranties or support?

Cheers, Grant  :)

Technical Support / 100mm f2.8 L Macro - to filter or not to filter?
« on: October 29, 2013, 05:47:10 AM »
Hi all,

my wife has bought a 100mm 2.8L IS USM Macor lens for her wedding photography - nice closeups on the rings and a good lens in general.  She has a habit of using lenses as battering rams and not using lens hoods "because they are fiddly".  It takes a 67mm filter.   She is insistant on not fitting a filter to it.  Can anyone out there please give me a difinitive answer to the following questions:

1) can I use a filter on the macro lens without it causing vignetting?
2) is there a recommended filter to use (or a type of filter NOT to use)?

thanks in advance,

Grant  :)

Lighting / Infra red flash / lighting?
« on: October 21, 2013, 06:34:50 AM »
Hi guys,

I'm looking at getting my 40D converted to IR so that i can get some nighttime snaps on animals on safari next year, as we're doing a couple of night drives and for obvious reasons can't use white light.  I've found a couple of reputable companies in the UK that can do the IR conversion, so that's nice and easy.  The only tricky part is the lighting side of things, as it all seems to be pretty expensive.

I'm a bit weight limited on the trip, and some of the IR "lights" are quite heavy even thoug they are LED.  As such, I was thinking of converting a flash unit.  I have found some IR-transmissive perspex that only lets IR light through, and was thinking of getting a Yongnuo 560, taking out the clear lens and substituting it for a matching peice of IR transmissive perspex, thus giving me an IR flash invisible to the wildlife, but not to my camera.  I appreciate the YN560 isn't ETTL, and that's not as problem.

I appreciate that I will lose some light, and I'm expecting the wildlife to be circa 20m away.

Any thoughts / suggestions on if this is a good idea, if anyone can recommend an alternative or a good supplier of cheap IR lights that have a 20m+ range?

Huge thanks in advance,

Grant  :)

Third Party Manufacturers / One-off Leica anyone?

It's for charity...


and people are saying $4K for a lens is a lot! ;-)

PowerShot Cameras / Powershot D20 replacement / update?
« on: October 07, 2013, 06:13:55 AM »
Just wondering if anyone as heard anything regarding a update for the Powershot D20?  I appreciate that it's a bit specialist, but I'm interested to find out if anyone truly believes that Canon wil be releasing an update to this underwater camera next year, as I have a bit of a diving holiday planned for mid next year and don't really want to fork out the >£1K for a DSLR case or risk my 7D getting ful of fish.  At the moment, it seems that the Panasonic FT5 and Olympus TG-2 are surging ahead in terms of underwater colour rendering and (Panasonic) in MP and scoring well in reviews, but I would rather keep with Canon.


Grant :-)
