  1. IMO, you don't need an expensive loupe to determine sharpness. A good 10X loupe from Peak would do the job just as well. I have used "branded" and "no-brand" loupes and with both types, I can still tell if a slide is sharp or not. It is a question of what to look out for. In the case of animals, look for the fine hairs on the eyes, ears, etc. But don't confuse sharpness with DOF.
  2. Hi everybody,

     

    <p>

     

    I went to a bird sanctuary today and had my Photo Trekker loading with about 18kg of equipment. After about half an hour of walking, one of the shoulder straps gave way. Fortunately, the other strap was till intact and this prevented my stuff from free falling to the ground. Upon closer inspection, I noticed the stitching had given way.

    Although I have had this bag for about three years now, it was used not more than 15 times. I normally switch between this bag and my Tamrac 777. This incident has caused me to become wary of Lowepro bags.

     

    <p>

     

    Anyone with similar experience?

  3. Kent,

     

    If I have to choose between buying a tripod and a ballhead, I would go for the tripod. It seems to make more sense getting a sturdy tripod than buying a good ballhead. After you have invested in a better tripod, start saving for the Arca Swiss B1.

  4. The 7II has multiple exposure function and comes in two colours -

    black and champagne(?). The coating of the viewfinder has also been

    improved to allow for a brighter image.

  5. I also share the view that a 400 f2.8 may not be the best super telephoto lens for nature photography. Given the chance to buy again, I would still opt for a 500 or 600mm lens. My reasons :

     

    a) A 500mm lens is cheaper. For the price of a 400, I would rather add a little more and get me a 600.

    b) I hardly ever shoot at f2.8. Most of the time it is f5.6 or higher.

    c) Given the weight, I rather go for a 600mm.

    d) I often find myself shooting at 500mm and above. Rarely do I shoot with my 300 f2.8.

     

    Having said this, I am sure that the 400mm f2.8 is a superb lens and that some folks will find this lens more practical for their own reasons.

  6. Mike, I did not test the Sigma 2X APO teleconverter with the older

    Nikkor 80~200mm f2.8 but I did test it with the AF-S 80~200mm and AF-S

    300mm and it did not work. It could autofocus the lenses but it could

    not lock on to the subject. Manually focusing, the images made with

    the Sigma APO 2X teleconverter was about 2/3 stop under with the AF-S

    lenses.

     

    <p>

     

    If I am not wrong, this converter is suitable for the older version of

    the Nikkor 300mm f2.8 lens. I don't think it is suitable for a 80~200

    lens but I could be wrong here. Suggest you check the instructions in

    the Sigma box.

  7. Bob,if you want the best, then get the RRS. From what I can see, the RRS flash bracket and lens plates are very well made and I doubt if Kirk can do better. I have a couple of RRS plates as well as their flash bracket. I also have one Kirk lens plate and it is not as well made as the RRS. But that is not to say that Kirk's plates and brackets are not useable - just not as good as RRS.

     

    If the price is about the same, I would recommend you go for the RRS.

  8. What Ivan said is true. There is certain to be some degree of

    distortion in WA lenses. This is especially so in zooms. The 24~50mm

    is a good lens.

     

    <p>

     

    I have the 20~35mm f2.8 which I consider a very good lens. It does

    exhibit some distortion but you can minimise this by the way you

    position yourself and the distance of the subject from the camera.

  9. John, I would go for the Provia 100. Push it one stop if you must.

    This is the film I used most besides Velvia. The weather during that

    time should be good so you may not need a fast film(depending on what

    you shoot).

     

    <p>

     

    Also, while in Germany, don't forget Rothenburg ob der Tauber. It is

    near Ansbach. Ask the locals for directions. I discovered this

    medieval jewel last December. It's a very old town with beautiful

    buildings.

     

    <p>

     

    Enjoy.

  10. I believe the above posts all advocate the same thing:

     

    <p>

     

    a) Dust in the lens is not likely to affect your images and

     

    <p>

     

    b) If you really need to clean the lens internally, send it to the

    manufacturer.

  11. I believe the MN-30 battery you are referring to is Ni-MH and not

    Ni-Cad. I used to use alkaline batteries for my F5 but have since

    switched to the Ni-MH batteries. Since I don't keep track of the

    number of rolls per freshly charged battery, I can only give you an

    estimate. It is about 25 rolls, probably slightly more.

     

    <p>

     

    It will be interesting to find out what other users have to say.

  12. I am not sure what you mean by "a ton of dust" but generally, I

    classify dust into two types - "white" dust and black dust.

    Personally, I find the "white" dust harmless. It is the black dust

    that gets on my nerves. I believe the black dust are mostly the

    internal paint/material used to coat the inner barrel of the lens to

    prevent reflection. They fall off because of vibration or perhaps due

    to aging. From what I know, even the black dust will not affect your

    images provided they are not big. You have to remember that because of

    the glasses in the lens, small/fine dust are magnified and so may look

    big. I know that even the Leica lenses are not immune to dust.

     

    <p>

     

    Having said this, I have to admit that I can't stand dust in my

    lenses. I have opened up my lenses to clean them myself. Even my 500mm

    f4 is not spared. However, I must caution anyone attempting this that

    the stakes are much higher with a super telephoto lens. And if you

    have never opened up a lens before, don't try it yourself. Send it to

    the manufacturer.

     

    <p>

     

    The impact of having a clean lens is more psychological than anything

    else. Needless to say, after the cleaning, the dust will come back

    given time and usage.

  13. By definition, fill flash should mean using flash light to enhance the

    existing light(especially where there are shadows).The main source of

    light is still ambient light and the flash light does not overpower

    it.

     

    <p>

     

    When you shoot with a F5 plus flash, the normal sync is about 1/60

    sec. However, if you shoot in bright light, the flash sync may go up

    to 1/250 sec. The F5 can go up to a max of 1/300 sec but you need to

    do some adjustments.

     

    <p>

     

    As for the "slow sync", that is usually 1/30 sec. But one can always

    adjust in manual mode the sutter speed to lower the speed. I do not

    shoot at "slow sync" mode. I normally shoot at 1/60 sec with a minus

    1/3 compensation on the SB 26 flash. I have also shot without any

    compensation on the flash and the image turned out alright. If I need

    to use a slower shutter speed, I will adjust the shutter speed in

    manual mode. A lot also depends on what you are shooting. A white or a

    black subject may require different compensation. A moving subject may

    require a faster shutter speed.

  14. Hi,

     

    <p>

     

    I suspect this topic may have been covered somewhere. I would like to

    have your comments on the effects of flash lights on animals and in

    particular, insects.

     

    <p>

     

    Recently, I noticed that while taking shots of butterflies in broad

    daylight, the insects reacted everytime my flash gun goes off. It took

    me by surprised as this is the first time I experienced this. I know

    some birds are sensitive to flash lights but butterflies? Anyone care

    to share his/her experience?

  15. I believe I've got the Bogen long lens support you mentioned. Mine is

    definitely not suitable for vertical shots so I wouldn't recommend it

    to anyone. Don't get me wrong. You can rotate it for vertical shots

    but the process is too cumbersome. That is the reason why mine is

    sitting somewhere in my cupboard collect dust!

     

    <p>

     

    I'm not sure what system you are using but I would suggest you get a

    used 300mm lens with a tripod collar. It is worth all the hassle.

  16. Hi David,

     

    <p>

     

    I like your interest. You jump from one subject to another like a jack

    rabbit;) But seriously, if I were to shoot a wasp, I would probably

    use a 200mm marco lens to keep the distance(don't want a sting for no

    reason). I would not rule out a tripod as I may want to prefocus on

    a particular area and wait for the subject to be in focus.

    Handholding is possible but I would prefer using a 105mm macro

    instead. However, if you want to shoot a wasp in flight, I would

    advise you to bring plenty of films and pray for good luck. Your best

    bet is still to wait for it to land at an anticipated area(flower,

    hive, etc)and then shoot.

  17. Seems nobody is keen to be a professional nature photographer. I guess

    nobody wants to turn an enjoyable hobby into a full-time nightmare!

     

    <p>

     

    Nevertheless, you folks in America and Europe should take consolation

    in the fact that it is even harder to make a living being a nature

    photographer in Singapore or Asia for that matter. I know of only one

    guy and he told me it never pays enough to cover his rent. He has to

    double-up doing something else in order to make ends meet.

     

    <p>

     

    Having said this, I must add that I will be tempted if someone wants

    to engage me on a project basis. I get paid for the job without the

    hassle of actually running a business. Not too bad, don't you agree?

     

    <p>

     

    By the way, I am a businessman myself.

  18. Hi,

     

    <p>

     

    To the best of my knowledge, I have not noticed any effect of the AF-S

    focusing on the animals or birds that I have photographed. I haven't

    tried shooting my bull terrier though!

     

    <p>

     

    To-date, I have shot about twenty rolls of Provia with the AF-S lens

    and it is aperture priority with about 70% autofocus and 30% manual

    focusing mode.
