Camera Advice
May 1st, 2008
ChasingToddlerMom asked SavvyDad for some advice on buying a camera fast enough to catch our little ones in action. I thought you all would be interested in his response…
***********
STM told me you’re looking for a new camera. Click here for a side-by-side of the cameras you mentioned.
Given this comment: “One of my very highest priorities is to be able to take a decent picture at a quick shutter speed…” it follows that more important even than the camera body (since all 4 that you mention can operate at ~1/4000s max shutter speeds) is the lens. The lens will determine how fast light can get into the camera.
A cheap lens won’t let enough light in during a 1/4000s shot to get a proper exposure. The camera, anticipating this, will slow down the shutter speed to allow more light in (for correct exposure), but gives your subject time to move while the shutter is open.
Here’s my order of preference of the cameras you suggested:
1) Nikon D60 - allows unlimited continuous (’rapidfire’) shots, great variety of available lenses
2) Canon Rebel XTi - plastic body feels iffy, but Canon also has nice lenses available
3) Sony A200 - Sony is new to the DSLR market. This is their second gen camera
4) Sony A100 - Their first DSLR. You know how when Windows XP first came out it wasn’t too stable? I think the same applies here. Sony’s big selling point is that ‘only their camera body’ has Image Stabilization - which is true, but only ’cause the other cameras put stabilization in the lenses.
Here’s the catch:
1) All 4 of those cameras come with equivalent kit lenses (18-55mm, f/3.5-f/5.6) Not especially great, but adequate.
2) You can tell a good lens by the f-number. An f/2.8 is a nice lens, an f/5.6 isn’t. This number corresponds with the max opening the shutter can have - and the more open the shutter, the more light can get in - this makes for quicker exposures. Nice lenses are “fast.”
3) Fast lenses are expensive (for example: Nikon 18-55mm f/3.5-5.6 is included, but the Nikon 17-55mm f/2.8 is $1200).
4) They include mediocre kit lenses with the camera so you’ll go by their nicer ones. And only Nikon lenses fit on Nikons, only Canon lenses fit on Canons, etc.
Here’s the conclusion:
1) SLRs are flexible, but it requires some know-how and some $$ do take advantage of it.
2) You can get fast cameras without, necessarily, an SLR, but be sure and look for that f/#. I suggest www.dpreview.com/ as a resource.
3) Once you settle on a couple of models, go to a camera store and hold them and try them. This is critical.
4) Pay attention to startup times and to shutter lag - the time from pressing the button to hearing the click. Shutter lag is death. Don’t by a camera that has shutter lag and don’t buy a camera that starts up slowly.
Hope this helps. Let me know if you have further questions. I love talking about this stuff.

BPA - Bisphenol A; Some answers
April 18th, 2008
I’ve noticed a lot of chatter lately about a chemical found in plastic bottles called bisphenol A (aka BPA). Consumer Reports, National Public Radio, the Canadian Government, and the US Department of Health and Human Services, have all recently published warnings about this chemical.
I’m not a medical professional. But here is what I’ve been able to determine:
1) The plastics industry assures us that there is no problem. (What a relief!) The website factsonplastics.com (run by the American Chemistry Council, formerly known as the Chemical Manufacturers’ Association - an industry trade association for American chemical companies), “affirms that there are no serious or high level concerns for adverse effects of bisphenol A on human reproduction and development.” Interesting wording, huh? “No serious or high level concerns…” Wow. I wonder what they consider ’serious.’ It feels like they’re doing the same thing they did with tobacco and global warming - slander the science, insinuate a lack of consensus and let Fox “News” do the rest.
2) We can be exposed to BPA when it ‘leaches’ into the liquid or food we consume from a BPA lined container. Not all plastics are made with BPA, and not all plastics leach equally. Plastics can be identified by the ‘number in the triangle‘ usually on the bottom of the container. The number of concern is the 7 - and not all #7 bottles contain BPA, though I’ve read there is, “controversy of these bottles not being labeled with any code so that consumers cannot tell what type of plastic is used.” (Oh, great.)
3) The chemical Bisphenol A is worrysome “because it mimics estrogen and thus could induce hormonal responses.” This could be particularly hazardous if a developing child/fetus/toddler/teenager is exposed. There is less of a concern for adults who are not participating in the reproductive process.
4) The National Institute of Health has this to say about it, “…there is some concern for neural and behavioral effects in fetuses, infants, and children at current human exposures,” and that there is “some concern for bisphenol A exposure in these populations based on effects in the prostate gland, mammary gland, and an earlier age for puberty in females.” Additionally, “…exposure of pregnant women to bisphenol A will result in fetal or neonatal mortality, birth defects or reduced birth weight and growth in their offspring.” (full article here)
To limit your exposure to BPA, the NIH lists some recommendations at the bottom of this page.
It’s not like we need one more thing to worry about. I just can’t help but think of the hat makers who used mercury to stiffen brims. I wonder if Ye Olde Hat Makers’ Brotherhood was pissed when “so-called scientists” told them to stop using a poisonous chemical in their manufacturing. How did plumbers and water pipe makers react when “science” said to quit using lead in pipes? I don’t know for sure if BPA is as bad as some say, but when it comes to health concerns, I’ll pick science over industry every time.
One Stop Motors - I Smell a Scam
April 4th, 2008
[SavvyDad is guest-blogging today - Thanks, hon!]
I think I almost got scammed by onestopmotors.com. I had to post a review of my experience. If you don’t want the details, skip to the last two paragraphs.
I was toying with the idea of selling my car recently and posted an ad in the local classified website, kslcars.com. The site allows you to post images and a description of your car - no charge. It goes in their database which is easily searchable by year, price, mileage, vicinity, etc. Very easy to browse for a car. No complaints about it.
Two days later, I got a call from a rep from One Stop Motors saying they saw my car ad on KSL’s website. They told me they can sell my car for more than I’m asking and that I can keep all the money they get for the sale. Naturally skeptical, I asked how they make money. He said, “By arranging the financing for buyers.” I was stuck in traffic and figured I could listen to the rest of the story. What followed was a very savvy sales pitch.
I gave them some specs on my car, and they gave me a quote about $1500 more than I was asking. For a $500 fee they would advertise my car on their network until it sold by doing keyword buys for search engines, posting on their affiliate sites, etc. Since ads cost money, they say, it’s in their interest to sell my car quickly. They told me they’d keep advertising until it sold, even if it cost more than the $500 I would be giving. It did make me wonder who would ever buy from them, though. You know they’re asking as much as they think they can get - more even than the actual owner thinks is fair. Whatever.
After their pitch, I expected some pressure to close the sale. To my surprise, it didn’t come. I said I’d think about it. He asked when he could call back. I said, effectively, “Don’t call me, I’ll call you.” “Okay,” he said. “Let me email you that quote and our website so you can check it out.” I gave him my email address, and that was the end of the call.
That email never came and a week later he called back. In the meantime, I went to their website and googled their name. The site looks legit enough. The other search results were …peculiar. The first results were mostly links to them. The #3 result was from a site called “Rip-Off Report,” with this blog entry, which reads like a sales pitch, clearly not an objective assessment of someone’s experience. Get this quote: “…they continue to fulfill their commitment to superior customer service…” and “*UPDATE Employee.. inside information ..OneStopMotors provides everything they say they will.” (How reassuring.) They clearly have a wide network of rather disingenuous bloggers. Many dozens of search results have URLs with some permutation of their name. I can’t prove they’re trying to drown out dissent, but if you were going to, this is exactly what it would look like.
So I go the the Better Business Bureau site and find this page which reports “this company is not a member” and “The company has an unsatisfactory record due to the failure to eliminate the underlying cause of consumer dissatisfaction.” This causes me to look deeper into google search results and find individual experiences. Then I ask myself, “If I give them $500, what keeps them from doing nothing?” According to one customer, “they keep calling untile[sic] they get your credit card # then you never here [sic] from them again.”
When I got the next call, I said I would not be doing business with them as I saw they weren’t members of the BBB. The sales rep told me, “The hell we’re not!” (They’re not.) He then insulted me and asked if I realized the volumes they deal with. Before I could respond, he hung up on me. It’s possible he had a point. According to the BBB, of “168 complaints in the last 36 months, 66 were closed in the last year,” which tells me they have made some efforts to resolve complaints. Whether it’s because they care about the customer, or the just bad publicity is anyone’s guess. FYI, Costco had a total of 257 complaints in the same time period.
I would not do business with One Stop Motors. If you pay $500 and they do a crappy job, you have no recourse. They have no incentive to be a strong advocate for you since they a) already have your money and b) have flooded search results with their sites, effectively burying objective evaluations/dissent/complaints. If you found this when researching these guys, then you’re a pretty savvy reader.
