Long time lurker, first time poster. I've been reading various threads and reviews regarding the "travel zooms", and I'm amazed at the prejudice against them by many "pros" and "primers". I'm not a pro, but maybe someday.... For now I'm a hobbyist, and my photography is about 80% documentation and 20% attempting to "record images" in a more artful way. Perhaps the anti-super-zoom bias I am seeing is due to many posters here being just "image creators" and not "documentors", but I would venture that DPREVIEW is more heavily USED by hobbyists and amateurs like me who are looking for information to help them make choices and get better at photography.
I've been shooting for 35 years and have spent some money over that time, but I'm not rich. I have to choose equipment on a tight budget, aiming to collect lenses that will give me the best chance of catching all the moments I need to in addition to allowing me to perhaps create more "masterful" works. I am often constrained by my choices of location, which in recent years involve long-ish hikes in remote areas. In particular, I've been going into slot canyons in Utah and Arizona, and these trips involve clamoring over boulders and climbing up and down - sometimes squeezing through tight spots. For this reason, I can't carry four different prime lenses along with my food and gallon of water - just too much. So what? Well, it means that a so-called travel zoom is really one of the best options I have besides downgrading to a point and shoot. I am shooting with a D-90 (I suppose that in iteself will earn me some upturned noses). I currently have Nikon primes of 28, 35, 50 and 300 along with some midrange zooms (the kit lenses), but none of these give me the complete flexibility I need in a slot canyon. I also have the Sigma 10-20 and a macro, but again they don't give me all the choices I want for framing my shots. Somewhat obviously, these are low light situations and I use a tripod, so the speed of the lens is not a major factor. A final relevant note - changing lenses in dusty, very rocky canyons is not ideal due to the risks of sensor contamination and dropping something and having to carry the resultant junk out in my pack.
Now, my wife was given a Nikon 18-300 for Christmas and she loves it. I have been quite impressed with the quality of many of her shots both near and far. I'm considering getting a similar lens - perhaps a less expensive competitor like the Sigma 18-250 w/macro - because I could stick it on my camera and be ready for most situations in the slots. I could then pack my 10-20 in my bag (it's a no-brainer among my lenses for getting interesting perspectives in confined spaces) and feel that I have a good chance of getting some great photos. I will mention that shooting with an 18-105 on some previous trips, I have come away with 20x30 prints that I think are fantastic. I would just like to have a bit more reach and not have to crop, since for now I don't have 24 or 36 megapixels to work with. Can someone tell me where the flaw is in my thinking? Here are my points:
1. Zoom lens IQ is lower than primes (generally - as stated in thousands of posts in dozens of forums and verified by testing and commented on by the experts). Does this really need to be brought up in every new thread about zoom lenses? Do the posters who parrot this believe they are telling anyone anything new, or are they just showing us all how smart they are?
2. This forum is about helping people get information (reviews), not just to discuss.
3. People on a budget cannot afford multiple $1,000+ prime lenses very easily.
4. I need flexibility for my chosen venue - the more the better.
5. Lens manufacturers are making significant headway towards creating super-zooms that are good performers. Is it wrong thinking to take advantage of this?
6. Does it make one a better or more artful photographer because they "zoom" by changing their lens instead of turning a ring?
7. Does a forum noob have a right to post such heresy?
