  1. <p>For wildlife on a budget, I'd agree with the FZ-8. It goes long, but not wide.<br>

    The LZ-8 is smaller and cheaper, but doesn't have the reach you'd need for wild animals.<br>

    (an example pic taken with a predecessor to the FZ-8, at max zoom)<br>

    I guess the question is, how often will you be in a position to take pictures of wildlife, and conversely, how upset would you then be if you could't...</p>

  2. <p>Since you want to use this system for architecture, you should check that you can get rid of the lens distortion in post.  Especially the Canon 24-105 is tricky in this regard, but should be supported soon by DxO.<br>

    As for the tabletop photography, you need to figure out the size of your subject and work from there.  Extension rings for the 50mm lens could be a cheap way to get closer:<br>

  3. The digital cameras are optimized for autofocus: Half of the light goes to the AF sensors, the viewing screen does not have focus aids, and the stated viewfinder magnification needs to be divided by the crop factor (e.g., .95x/1.5=.63x for the K10D). Moreover, digital seems to be more sensitive to focus errors than film.

     

    In other words, you may want to try before you buy, and consider adding a viewfinder loupe and/or another focusing screen to your budget.

     

    All Pentax K mount lenses will work, but be careful with others: I had problems with an old m42 to bayonet adapter getting stuck to the mount.

  4. The main source of noise (poisson noise) depends only on how much light hits the sensor, i.e., shutter time and aperture. A picture taken at ISO 1600 and one taken at ISO 800, with the same shutter time and aperture and brightened by one stop in post, have the same amount of poisson noise.

     

    Then there is readout and reset noise, which is "constant", and shows up more when you underexpose and later brighten the picture. As you say, it has an impact mainly in the darker areas of the picture.

  5. The OP did say "I research the best gear" and "I want a good tripod". There are many of the latter, depending on purpose, so a budget would help narrowing the field down. As for a positive contribution, I offer the following link.

    "If you need a less expensive solution and know you won't be shooting with lenses over two pounds (basically under 300mm), there's another solution [at $600+] I can recommend that gets you almost everything the other does"

  6. Working at full zoom, as suggested above, is what I'd try first. It both reduces the maximum aperture (the proportion of light that hits the sensor) and increases working distance making the flash less powerful (light falloff = distance squared).

     

    If it doesn't help, you could also get some Neutral Density filter or diffuser (think pringles can lid) and tape it in front of the flash. It will reduce the amount of light that reaches the subject.

  7. I had the Tamron 18-250, and would buy it again. It's great for holidays, small and light, and has the best image quality of the off-brand superzooms (very similar to the kit lenses mentioned above, slightly below the Nikon 18-200). If you want to use the long end, you need good light or to get the Sigma with OS.

     

    For portraits, I've got another Tamron, 28-75/2.8. You already have these focal lengths 'covered' but if the zoom range works for you too (try it), it gives you more options in terms of aperture choice and low-light capability.

  8. At your budget, the Canon 400D probably has the best AF system for low light, or a used Canon 20D if you want better ergonomics. Both have very good noise characteristics at 1600, better than 35mm film and most/all the digital competitors (at the same price). Upgrading your lens may be more important than the body you choose, though.

  9. The bad news is that indoors action is one of the most demanding areas of photography, and that the FZ50 is the proverbial jack of all trades (except that it has no wide-angle).

    The good news is that it has a flash shoe, so you can add an extra flash for better results. An SLR setup is of course better, but significantly more expensive.
