To those of you working your way through this series…. STOP… you will never get your time back and, if you’re like me, you will cry yourself to sleep every night for the torture you endured. If you’re a 14 year old girl, or if you simply choose to disregard this warning…May god have mercy on your soul you poor, poor S.O.B.!
Nikon 400mm f 2
This is my first iPod Touch and I enjoy every minute. I’ve been an iPod Nano 3rd Gen, but broke it at the gym, I really hit it on one of the machines. I was debating about getting a nano or an iTouch, but I’m glad I chose the Touch. The bad, there would be no camera, the battery does not last long, and a wireless connection for some of the features. The good, the loot in the Wi-Fi, tons of free apps to be easy to use interface. I recommend the 32GB or 64GB on the 8GB and the 8GB is truly a 2nd Gen, not so fast when it comes to games, I have the 32GB and I see a difference.

This lens feels solid, looks good, and works well. It’s for Canon digital (APS-C sized sensors) only, there’s also a version for Nikon and Sony setups. The focal length is the equivalent of 93mm in the 35mm world. This is very close to the traditional 100mm Macro lens length. But it’s a full stop faster than either the Canon EF-S 60mm macro (f/2.0 vs. f/2.8) or the Canon EF 100mm macro (full frame usable, f/2.0 vs. f/2.8 again). And it’s more expensive than the Canon. Usually the third party lenses appeal to us on cost, but not here. The appeal and what you get for your extra money is a full stop of additional light gathering ability.
Price aside, this is a very nice lens and no Canon system owner would be unhappy with it. Until there’s a Canon L-series Macro in the 100mm focal length range (in 35mm terms), either the Canon or this Tamron are as good as it gets. But the cost? I’m using this lens and reviewing it, but I’d probably purchase the cheaper Canon lens myself. In my own macro photography I typically want as much depth of field as I can get. Typically outdoors I’d shoot at f/5.6 or higher. Indoors, with lights, f/11 or 16 is more typical. For how I do it, that extra stop isn’t too useful. Your mileage, obviously, would vary on that issue.
Tamron AF 60mm f
Actually my review is somewhat similar to the previous review by W. Cooper. I, like him, didn’t find much resources about this lens, but was confused between the Tamron & the Nikon long range lenses, I was about to go with the Nikon 18-200mm because I felt that the Tamron 18-270mm lens didn’t really get good reviews and I didn’t like the fact that it was slow in focusing. And boy am I glad that I waited for this one. I think I gambled (being an early adopter) and it worked.
Its really a great all around lens which is exactly what I was looking for (I hate changing lenses). The best thing about it is that its really pretty fast in focusing at 250mm, maybe even faster than my D90 kit lens the Nikon 18-105mm. It really is a HSM equipped lens, I saw a few threads in forums about ppl debating this fact, so rest assured it has a motor. The OS is working as it should at maximum zoom as well so no issues here. I have been using it for a couple of days only to be fair, but I’m very excited about it and about the quality of the images I have took so far. I’m taking it out for a full test in the next few days, if I feel that things weren’t perfect I will update this review. I didn’t notice a lens creep (yet!), but in any case there is a lock switch on the lens, this switch will only work when the lens is at 18mm. I noticed that when you are trying to shoot close-ups at 250mm, the lens wont focus properly if you are too close to the subject, manual focus will still work though and you can take a clear sharp picture. The make and the body of the lens feels nice and durable as well, it doesn’t feel cheap at all.
In the end I have to say that this baby will beat the Tamron 18-270mm lens hands down, and surely the Nikon 18-200 if you want a bigger zoom. And the price is surely worth it and acceptable.
Update: I think I was wrong about close-up focus, it still focus pretty well and fast at close range while at maximum zoom.
Update 2: I have uploaded some pics in Picasa
Sigma 18 250mm f | takemetoyourrobot
Sigma 70-300. Great lens for a newbie SLR user.Very Happy with the lens , the pictures are sharp and the autofocus is fast.
Good buy. For the price this is a good choice. It is of course slow at tele and not good in low light, but is very good in bright sun, no matter what.
