    Canon EOS 1D MK II

    You say that sometimes it locks up. Is it always with the same card by chance? I had a Sandisk extreme II that I found to cause that problem on occasion. I got a free replacement and have had no problems since. I think the camera was trying to save to a faulty location on the card and hung...

    Canon 1D II - AF issues?

    AF 1D MKII issues I have also just upgraded, but to a 1Ds MKII (rumours of an S MKIII have prompted some great deals to appear). But I am keeping my 1D MKII also, and using it with telephoto lenses where it will serve every bit as well as the s. I have never had a focussing problem - in fact...

    Leica 7x42 Ultravid v Leica 7x42 BN

    Not that this adds much to the comparison discussion, but I bought the 7x42 BNs a while back, as well as some classic Zeiss 8x30's with the latest coatings. Both were brand new, but deals I thought. I'm not sure why I did it, other than I had some money in my Paypal account, because I thought...

    Difference between BA and BN?

    BA vs BN Interesting that the colours and serial numbers don't seem to transition smoothly. I just recieved a new pair of 7x42 BNs and see that the coating colour is indeed green and purple. For the life of me I can't see any difference in contrast ( or even brightness, but my pupils don't...

    Difference between BA and BN?

    Thanks. I guess there was a change shortly after mine were produced.

    8x32 Ultravid vs 8x32 Trinovid - Differences

    I am talking about the slc too. Are you interested in selling that?

    8x32 Ultravid vs 8x32 Trinovid - Differences

    Hi Michael, I'm not sure what 7x42s you have left, but are you interested in selling any (rather than donating)?

    Difference between BA and BN?

    This thread is of interest to me as I just purchased a pair of 8x42 BAs. The serial number is 1088140. The coatings appear yellow and purple when looking at light reflected in the objectives. I would be interested to know what the coating colours are on the later versions. Incidentally, I...

    Choice: 300mm f/4 + TC 1.4x or 400mm f/5.6?

    Check out www.photozone.de for tests. But I still don't understand the IS not being an issue if it is a walk-around lens...

    Pentax 100mm the path to high-power spotter nirvana?

    I agree with you. A decent review of a product is good. But the attack on BVD and Televue was surprising, and had little to do with the review of the Pentax. I own the Pentax 80, by the way, and like it a lot, except for the width of the zoom eyepiece.

    Pentax 100mm the path to high-power spotter nirvana?

    Wow! Did Televue fry your socks or something? A much shorter statement would have sent your message about suitability without making it sound like you are on a mission. Just a quick question about your setup - are the eyepieces you are using in the Pentax waterproof?

    Which Lens for Landscape

    There is one other lens that you might want to consider, and that is the Canon 24 tilt/shift. I have found it truely excellent for landscape as its resolution is better than my Canon zoom, and it allows adjustment of perspective and focus/depth of field when needed. If you ever venture into a...

    Is IS worth it if you have decent legs?

    Since I'm in Canada I will obviously say that the lenses they send here are the best! But that would be an unreasonable assumption - I'm sure they send the same quality lenses everywhere. I haven't any experience with the two 400 lenses, but use the 300 f2.8, without IS, and have to admit I...

    Which is better SRGB or Adobe rgb

    After much more reading, and learning to use photoshop's soft proofing properly using the actual printer/paper profile for that purpose, and the out of gamut warning, I am convinced that the best way to go is to use the actual camera colour profile all the way up to the last minute, the print...

    Which is better SRGB or Adobe rgb

    This is getting more and more interesting. I read more and think of more questions. Something that I just saw suggests that I save my files (tif or photoshop format) with the embedded camera profile. Phase One has profiles for each camera that are obvious (I think Camera Raw has them too but...

    Which is better SRGB or Adobe rgb

    Well Christine, that makes perfect sense, but I've never thought of it. I use Phase One (LE) raw converter, and now that I do think of it, I've never worried about colour space in that. It only seems to become an issue when I'm creating TIF files and printing (maybe???). Have to back and look!

    Which is better SRGB or Adobe rgb

    My limited understanding of colour spaces, or 'gamuts', has been gained in reading many articles on the topic. Unfortunately I forget much of what I read just once, but from what I have gleaned colour spaces such as AdobeRGB can be larger (contain more colours) or smaller. I have never heard...

    Canon zoom lens

    Hey Kristy - just have to put in my two cents worth about the quality of pictures and sing my old refrain about tripods. Until I started using a good tripod and head, even on warbler pictures (if you know warblers, you know what I mean), I was never excited about the results. With the tripod...

    Just received my 20D......advice please

    Compa had some really great advice - use the camera's capabilites to the full. Since you have access to photoshop (and the raw converter?) I do suggest shooting Raw. I have done both and was often disappointed when I was looking at my shots, seeing something terrific, wanting to clean it up...

    Tripod/monopod support for large Canon lens

    Hi Paul, I do have results and they are quite impressive, particularly when blown up to 100%. I could try to send you a small piece of a photo, but the screen resolution will not show the detail that is there in a good print (I use an Epson 4000). More importantly, I am on an incredibly slow...

    Tripod/monopod support for large Canon lens

    I use a Canon 300f2.8 with 1.4 and 2x extenders on a 1D MKII, so the combination is pretty heavy. I use both a monopod and tripod (cheap Manfrotto monopod and Gitzo 1375 tripod with Arca Swiss monoball). Each has it's own place. For ultimate resolution (the kind you paid for with that 500)...

    Best Lens for birding with

    I don't know the Nikon world at all but I can tell you that in the Canon world there are two prime lenses that pros love for wildlife photography, including birds These are the 300 f2.8 (with IS, preferably) and, better yet, the 500 f4. Both are very expensive and pretty heavy but definitely...

    Wow! Just can't beat those fast primes (especially the 300's). Great catch!

    Canon EF 100-400mm IS or EF 400mm f5.6L

    You are right, of course, John. I have changed my technique because I love those high res images*, but I'm sure I lose out on many shots that I could have had. The point I was really trying to make was that all of these comparisons about lens resolution aren't worth worrying about unless one...

    Canon EF 100-400mm IS or EF 400mm f5.6L

    I have owned the 100-400 zoom, and sold it, and now own a 300f2.8 and the 70-200is and 1.4II and 2II extenders. After much experimentation I find that I absolutely have to have the lenses on a tripod to get anything close to maximum resolution. With a good tripod and head, and high ISO, the...
