wrote: Sounds to me like you could lighten your load considerably, and still do all those things, if you carried a good PDA. I just got an HP, and I'm still learning what it can do, but so far I am wondering why the hell I've been lugging my heavy laptop around when I can carry this thing that is about the size of paperback. Riverman, yes, I probably could. But then again I probably couldn't, if I wanted to do some work, because I need all my tools and all the processing power. I regularly use a lot of software that isn't available for PDAs. But I may be the exception. For most people a PDA may be a very good solution. On the other hand, who cares about the load? I don't travel with a backpack, I always have the jeep. No problems there either. On game drives I leave the laptop in the lodge, when I stay in one. Hans-Georg -- No mail, please. |

I had read two of your reports indicating that the 1Ds2 equals the quality of your 6x7. The fact that you have now switched says enough. I am using the 1D2 since last spring and although 8Mp is enough for me, I would love to have fullframe. A bit more back on topic now: How do you cope with backing up your shots when in Africa in a lodge with very limited electrical power? Most laptops will allow just 2-3 hours of operation and if you use an internal CD/DVD burner even much less.

I am using the 1D2 since last spring and although 8Mp is enough for me, I would love to have fullframe. For Africa, the 1.3 crop is an advantage if you ask me. I've considered a 1D MKII as my second camera (I obviously cannot afford to take only one camera if I'm on an assignment). The only problem would be that the 8 Mpixel is so much less than the 16.7 Mpixel of the 1Ds MKII, that this would become a pretty expensive backup camera, which I would not use much as long as I have the choice between the two. OTOH, if I buy a second 1Ds MKII I will really use both (with different lenses) as I used to do when I still shot on film. Guess I'm waiting for Canon to bring out the 1D MKIII with 14 Mpixels and 8 fps... ;-) A bit more back on topic now: How do you cope with backing up your shots when in Africa in a lodge with very limited electrical power? Most laptops will allow just 2-3 hours of operation and if you use an internal CD/DVD burner even much less. Downloading a full 1 GB card takes about 3 to 4 minutes, so even after a very successful shoot it takes less than 20 minutes to get everything in the computer. It takes less than 10 minutes to backup all those files over a FireWire conncetion to an external hard drive, so the total time is about half an hour maximum. That means I can use my laptop without recharging for at least 4 days. I've never been in a situation where I couldn't recharge in 4 days. However, I do not take any risks. I have a 12 Volt to 220 Volt (130 Watt) converter, that plugs into the car cigaret lighter, so I can also charge laptops and cameras from the car battery if I need to. This summer I will probably do an assigment in Zambia, where I may spend quite some time in several bush camps. I'll certainly need the converter in that case! -- Johan W.

For Africa, the 1.3 crop is an advantage if you ask me. Indeed, the 1.3x factor performs practically as a built in 1.4x converter without the loss of light. So in practice my 500/4 performs as a 600/4 without the extra size and weight. I've considered a 1D MKII as my second camera (I obviously cannot afford to take only one camera if I'm on an assignment). The only problem would be that the 8 Mpixel is so much less than the 16.7 Mpixel of the 1Ds MKII, that this would become a pretty expensive backup camera, which I would not use much as long as I have the choice between the two. Well, that would depend on the type of shooting. If you are shooting animals and specially birds for books or magazines, the 1.3x factor is an added bonus and mostly 8Mp will be enough. OTOH, if I buy a second 1Ds MKII I will really use both (with different lenses) as I used to do when I still shot on film. Having two 1Ds2 bodies would be great, though they are rather expensive. For the difference in price you could also get something like a very nice 300/2.8L IS. Guess I'm waiting for Canon to bring out the 1D MKIII with 14 Mpixels and 8 fps... ;-) That would be nice. There are some romours about the upcoming PMA... Personally I am also thinking about a second hand 1Ds (first version) for fullframe. There are quite a few on the market, even hardly used ones for reasonable prices. But I would rather stay with the mkII extras (CF and SD cards, video out, big lcd screen etc) and have just one RAW format (CR2). Downloading a full 1 GB card takes about 3 to 4 minutes, so even after a very successful shoot it takes less than 20 minutes to get everything in the computer. It takes less than 10 minutes to backup all those files over a FireWire conncetion to an external hard drive, so the total time is about half an hour maximum. That means I can use my laptop without recharging for at least 4 days. I've never been in a situation where I couldn't recharge in 4 days. So you only load the images to your computer and back them up. You dont do a first scan through all the images to sort out which to keep and which to throw away? That would mean about an extra hour or so per day. However, I do not take any risks. I have a 12 Volt to 220 Volt (130 Watt) converter, that plugs into the car cigaret lighter, so I can also charge laptops and cameras from the car battery if I need to. I have never used such a converter. Do they work properly? Do you have to keep the engine of the car running to prevent sucking the car battery empty? By the way, the 4x4's I have used always had a second car battery installed. This summer I will probably do an assigment in Zambia, where I may spend quite some time in several bush camps. I'll certainly need the converter in that case! Where are you going?

If I shoot 16.7 Mpixels, my images can be submitted as they are. What kind of files do these stock libraries want: 48MB in 24bit colour (16 megapixel) or 48MB in 48bit colour (8 megapixel)? The biggest file I ever needed myself for a magazine publication (A4 covershot) was only 6 megapixel (scanned Velvia slides). That's why 8Mp is enough for me. Having two 1Ds2 bodies would be great, though they are rather expensive. For the difference in price you could also get something like a very nice 300/2.8L IS.

They work flawlessly and you do not have to keep the engine running. I never tried how long they work before your car battery is depleted though. ;-) Wouldn't you want to get stuck in the bush??? :-) The best method is to charge the laptop and/or the camera battery while you drive, so you have two to three hours working time in the evening. Just make sure the laptop is secured so the harddrive is being bumped around. summer I will probably do an assigment in Zambia, where I may spend quite some time in several bush camps. I'll certainly need the converter in that case! Need an assistant? :-) I'm married to my assistant. ;-) Can't compete with that! :-) Before I make such trips also with my wife. That got her interested in photography too. So now we can fight over who gets which lens and the best view. :-) But since we have two little children now, I guess we won't be able to make such trips into the African wilderness anymore for a while. A year and a half ago we made a trip to South Africa with our one year old son. But now with a 7 month old girl as well, we'll have to stay closer to home for a while.
