> [@KlondikeGeoff](#): > > Frankly, I don’t understand your vendetta against the Kindle and Amazon when you admit you you are not sure how it works, nor do you even have one. I have read over 200 books from Amazon and maybe 100 public domain books since getting my Kindle and have never, ever had any problem or trouble. The few books in question that sems to annoy you so much is a minuscule amount considering Amazon has more than 200,000 books available. Worrying about this is akin to worrying about getting stuck by lightening. The odds are astronomically against it. I don’t know all the specifics, but I understand the relevant and applicable operation of it. I feel passionately about issues of copyright, control, and technology. I worry that we’re placing too much faith and trust and power in the hands of corporations, and letting ourselves be tied down to specific devices that we can’t control. I don’t think that either Amazon or the Kindle are evil, but I do think that DRM is terrible, wasteful, and misguided. It’s true that the vast majority of users haven’t been affected, but the Kindle’s still young. The vast majority of [MSN’s digital music](http://arstechnica.com/microsoft/news/2008/04/drm-sucks-redux-microsoft-to-nuke-msn-music-drm-keys.ars) customers, or [Yahoo](http://arstechnica.com/old/content/2008/07/drm-still-sucks-yahoo-music-going-dark-taking-keys-with-it.ars)’s, or [Walmart](http://arstechnica.com/old/content/2008/09/wal-mart-latest-to-shut-down-drm-key-servers.ars)’s had no problems either, until those stores became unprofitable, and everyone who purchased music from them became unable to transfer it to new devices. I really hope that Amazon doesn’t go the same way, but I don’t have a lot of faith in that. I think that the chances that I will want to read a book I’ve bought after the corporation that sold it to me decides on a different business plan are significantly higher than being struck by lightning. I’m considering buying a Kindle myself, and I might actually pay Amazon for some books on it, but if I do, I’ll be renting them. Anyway, I’ve said my piece, and I don’t want to derail this thread further, so I’ll shut up about it here. To the OP: the Kindle looks to be the best e-reader out there right now, so if you’re going to buy one, that’s probably the one to buy. ---

I don’t think that the Kindal is back lighted, that Is something to consider. It’s nice to not need a reading light. ---

**enipla** , that’s a good point. I was already planning to take a netbook (my parents had an extra that didn’t work for them), so maybe I should look to that. The question is if we can get it working for me. ---

Sorry for the late-ish bump, but I was hoping some of the camera folks who contributed to the thread could comment on something a friend just suggested. [What about this “extender” with my kit lens?](http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=154&modelid=7463#ModelDetailAct). Of course, I’m not even clear that it’s compatible with my kit lens, but it was a suggestion a friend made, so I thought I’d ask people who know than the two of us. Or thoughts on some extender, I suppose. Thanks! ---

What’s your kit lens, a wide to short tele? Amazon has 45 user opinions about it: [http://www.amazon.com/Canon-EF-Extender-Telephoto-Accessory/product-reviews/B00009XVBY/ref=sr\_1\_1\_cm\_cr\_acr\_txt?ie=UTF8&showViewpoints=1](http://www.amazon.com/Canon-EF-Extender-Telephoto-Accessory/product-reviews/B00009XVBY/ref=sr_1_1_cm_cr_acr_txt?ie=UTF8&showViewpoints=1) Here’s a snippet of one: _It should be obvious - this extender really needs to be used with a tripod. That alone will increase your image quality. It’s also designed for the higher quality Canon lenses - the EF series. 90% of the complaints about this accessory ignore those two facts. The next biggest complaint - autofocus. Again, Canon is clear that you need a lens with an aperture of 2.8 or faster in order for autofocus to work. Basically, so what!

Thanks, **lobotomyboy63**. I think I like the lens you linked to more than the idea of the extender, and I CERTAINLY like the price of that lens. As you know, I’ve been trying to figure this all out for awhile, my deadline’s coming up, and I’m not figuring things out as quickly as I’d like. I’ll be buying something in the next couple of days, and hopefully it will work for me. ---

Inexpensive tele adapters are pretty much always a bad idea. Good ones cost some serious money but can be the right choice in certain applications. In this case, the Sigma lens would be a much better option. ---

No problem. I just went into amazon, thinking they’d probably have other brands (Tokina, Tamron, etc.) and found this: > **[Amazon.com : Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR...](https://www.amazon.com/Canon-75-300mm-4-5-6-Telephoto-Cameras/dp/B00004THD0)** > > Product Description Canon EF 75-300mm f/4-5.6 III Telephoto Zoom Lens for Canon SLR Cameras.

That lens will work, but the Sigma would be better. On the other hand, Sigma is notorious for bad quality control, so you run the risk of getting a “bad copy.” ---

Here are some choices, sorted by average customer review.

Apochromatic lenses are designed to bring three wavelengths (typically red, green, and blue) into focus in the same plane.[1]_ > **[Apochromat](https://en.wikipedia.org/wiki/Apochromat)** > > An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses. > Chromatic aberration is the phenomenon of different colors focusing at different distances from a lens. In photography, chromatic aberration produces soft overall images, and color fringing at high-contrast edges, like an edge between black and white. Astronomers face similar problems, particularly with telescopes t... Of course the next question is whether it’s designed and produced properly to function as advertised. IIRC I did read somewhere that Sigma’s QC wasn’t always up to snuff. ---

Thanks! Well, I’m going to buy something and commit to it. Going to have to, since I leave very soon. Somehow I blinked and it was time to leave. I’ll update the thread when I’ve gotten something, just to let everyone know. I’m super excited! Three months in Kenya, here I come!
