I know this is not a coin specific question but I thought you guys might be able to give an opinion. Please:) Sooo...I am going to Rome and I want to be able to take some good pics. I already have a Canon T2I and have considered taking it but I only have two macro lenses, a Canon 60mm and a 105mm. I am considering buying a new telephoto lens such as the Canon EF-S 55-250mm: http://www.the-digital-picture.com/...TM-Lens.aspxOr I am considering getting the pumped up point and shoot Sony Cybershot DSC-RX 100: http://www.amazon.com/Sony-DSC-RX10...p/B00889ST2GI am torn because I want to travel light and I want to have telephoto lens. The Canon option offers me more zoom which is very important to me. BTW, I have decided firmly that I will only carry one lens if I I take my T2I. The Sony is super compact but the zoom is only 3.6 optical. It is my understanding that the 54x digital zoom it offers will just make the pics more grainy. My budget is under $500. What do you think I should do? |

I've had my Cybershot everywhere and it is extremely versatile.
Unless you need super high resolution for some reason, the Cybershot does almost anything.
Take some time to learn it's system, which is not always intuitive.

I got the cybershot DSC-RX 100 version 1 for my wife for her birthday. It was an open box floor model at best buy for $250 (I know an open box gift is a crappy thing but what a great price!). She going on a 1 week camping trip on the pacific crest trail and need to be extra light. Let me tell you this thing takes GREAT pics. We have only used it on AUTO mode and its amazing. Open box or not she loves it. It takes no brainer photos as good or better than her Nikon d7100 DSLR. When she gets down to AV mode etc. I'm sure it will really shine. The version 3 has the same sensor, less telephoto but better wide angle(more useful really), and a hot shoe.

I've owned an RX100. For its' purpose, it is as good as they come and worthy of your most important pictures. But it doesn't have much for zoom.
Canon's 55-250 may be the best bargain lens they sell, possibly excepting the amazing little 40mm pancake. But, 55mm is way too long on an APS-C sensor to be a carry lens on a dSLR. So, neither of your choices are ideal; the T2i with two lenses (you have the 18-55, right?) is probably your best compromise.

I went to Best Buy today to check out the 18-55; it does not have the zoom that I am hoping for. I have purchased everything separate. Why is a 55-250 too long for a APS-C sensor? The guy at the store recommended the Sigma - 18-250mm f/3.5-6.3 DC OS Macro HSM Standard Zoom Lens. What zoom lens would you recommend for my T2i? |

Lens focal lengths are quoted in "35mm equivalent" numbers. APS-C sensors such as the one in a T2i are smaller than 35mm, and the same lens gives a smaller field of view on an APS-C sensor than a 35mm one. The math to do the conversion of sizes is called the Crop Factor; in Canon's case the crop factor is 1.6. That means a 55-250 lens on APS-C is equivalent to 88-400mm on 35mm.
On vacation, you need effective focal lengths of 20-30mm for "normal" images. Most point and shoot cameras are between 22-24mm effective at the lower end; this is the field of view we're "used to" for standard picture taking.
I know little about that long Sigma. Reviews indicate they've traded ultimate sharpness for better distortion and chromatic aberration - all zoom lenses are a technological compromise which is why we don't recommend them for coin photography - so although you should love it for carrying in Rome, you won't want it for coin imaging.
With that said, it's probably the lens which answers your needs from the original post. I'd happily recommend the Sigma for you, as long as the price is OK (I think it's a bargain). Just be aware it's not the sharpest lens available.

I should add: superzoom lenses like that 18-250 Sigma are rare in the dSLR world. The optical compromises have been too severe to allow dSLR image quality from that much zoom in one lens. The ones which have been produced have been rather mediocre lenses. It's only the last decade or so that quality has started becoming acceptable, and even then the best of them like this Sigma will not make a pixel-peeper happy. The compromises inherent in superzoom optics are less important on the far smaller sensors of point and shoot cameras, which is why they're so easy to find with long zooms. A high-megapixel P&S sensor is itself such a technological compromise that the lens becomes the lesser evil. That's why the RX100, with its' large sensor, has such a short zoom. Any longer would have provided inferior results. For trustworthy opinions of cameras and optics, I use DP Review, The Digital Picture, Photozone.de and Imaging-Resource as go-to sites. Here's the Sigma at DP Review: https://goccf.com/t/234762#1962580 |

Ssuperdave, thank you for your help! Your knowledge and time are truly appreciated. I am now deciding between the Canon Ef s 55-250 and the Sigma 18-250. I am leaning towards the Sigma but will see.
