Tamron 15x Zoom – Cannon and Nikon DSLR

Jay Garrett — Sat, 02 Aug 2008 14:03:20 +0000

We’re used to seeing 15x attached to point n shooters but for DSLRs it seems to be a different story.

Not for long though people!

Tamron’s new ultra zoom lens will set the record straight.

Apparently the first lens of its kind, the AF18-270MM Di II VC covers the 35mm equivalent range of 28mm to 419mm, and does so with a little help from Tamron’s proprietary tri-axial Vibration Compensation (or VC) mechanism.

This VC gubbins promises to eliminate, or at least, substantially reduce the effects of camera shake.

There’s not even a hint regarding price or release date but we are assured that the lens will be available in both Canon and Nikon mounts whenever it makes it out.

Nikkor 18-200 G f/3.5-5.6 ED-IF AF-S VR DX Reviewed at Photodoto

DSLRBlog Editors — Tue, 11 Jul 2006 10:37:19 +0000

Yesterday we looked at the Sigma 18-200mm and I mentioned that on Canon there isn’t a first party alternative but there is for Nikon. It turns out in the review at Photodoto that for Nikon owners, although pricier than the Sigma, the Nikkor is a great lens. He starts by doubting the need for such a lens first which isn’t a great start for the product …

I mean, who buys a high-end SLR with the intention of only using a single lens? I used to think no one did, but then this hit the market and you can’t even get it it’s so popular.

He does go on to say that he does like it and it is good value ..

Overall, it’s a nice lens and produces good images. If you’re looking specifically for something with an 11x zoom range, for whatever reason, you could do much worse than buying this lens. I’d recommend it if you have to travel light or for day trips with the family. It’s economical, too, when you consider the cost of buying two or more lenses to cover the same range. But any lens covering such a broad range has to make compromises. If you don’t mind switching lenses once in a while, you’ll get better image quality from more specialized zooms or primes.

I guess the main thing to separate the two will be price, you would be choosing either the low cost Sigma or the higher priced but VR-enabled Nikkor. Two slightly different markets I am thinking so the two will find their own following.

Carl Zeiss Lenses for Sony Alpha

DSLRBlog Editors — Tue, 06 Jun 2006 08:38:43 +0000

One thing I had missed yesterday when discussing the new Sony Alpha announcement was the fact in the official line-up there are Carl Zeiss lenses. It’s not as impressive as it sounds, not all the range is Carl Zeiss. Other sites seem to be buzzing with this news, for example The Online Photographer.

There is an official list of lenses, specifications and prices here in their accessories pages if you are interested, and you can check out what DPReview have to say.

Sony Announce α (alpha) A100 DSLR and 18-70mm Lens

DSLRBlog Editors — Mon, 05 Jun 2006 15:54:05 +0000

News just in from Sony, their much anticipated first DSLR offspring from their Sony-Konica-Minolta mashup, the Sony Alpha A100 DSLR plus 18-70mm lens kit. Judging from the pictures it looks pretty nice, pretty much standard DSLR fare. Only practical hands on experience would tell if it is usable and comfortable.

10mp puts it in competition, in purely sensor terms, with Nikon D200, D2X, Canon 5D, etc, although it is very strange the ISO starts at a wopping 160 – where is the ISO 50 and 100? It goes up to 1600 maximum. Not a huge problem but not a competitor to pro-level cameras that currently have greater range and also steps in between. Remains to be seen what the noise is like, presumably it is so good at 200 they do not see the need to go any further but as a ISO 100 user on a camera with great noise control I think they have missed a trick. The sensor is a 1.5x crop, like Nikon.

The kit lens is a pretty standard walk-around zoom, pretty bog standard. I don’t expect anyone to be jumping for joy but neither will too many people be disappointed, it would have been nice for them to come out with a real knock-out lens to get people talking.

Canon EF 70-300 f/4-5.6 IS USM Lens Service Notice

DSLRBlog Editors — Thu, 25 May 2006 08:43:35 +0000

I just found out my most recent lense purchase, Canon 70-300mm IS, might have a fault. Although I am obviously disappointed there might be something wrong at manufacture with such an expensive piece of kit it is pretty good to know that I found out from Canon rather than discover it for myself.

Apparently when used in portrait orientation at the longest length you get some softness at the edges. Not earth shatteringly awful, not ideal either. I applaud Canon for being honest about this, heck from what I have seen in forums outside of L/primes most 300mm lenses have a problem of softness at the edges anyway!

To Customers Who Use the EF 70-300 f/4-5.6 IS USM Telephoto Zoom Lens:

We have been studying the symptoms of this phenomenon in order to determine its precise cause and to develop an appropriate remedy. We will inform you on this Web site as soon as this remedy has been decided, which, at this point should be by the end of June 2006.

Lense Quality Comparison tool

DSLRBlog Editors — Mon, 08 May 2006 17:20:24 +0000

I just found what looks like a promising new tool for helping people select new lense purchase. It’s a fancy web application that allows you to compare crops taken with different lenses at selected focal lengths and apertures.

ISO 12233 Lens Test Chart 100% Crop Comparison Tool

While the choices are limited right now it does confirm what I thought about a couple of lenses I own, the 50mm 1.8 lense is damn sharp for the price!

Digital Technology Advances

DSLRBlog Editors — Wed, 01 Mar 2006 11:10:18 +0000

Digital Camera technology is moving ahead and it looks like it’s not just the hardware that will be the important element in future. Most interesting part of the news for me is the creation of new lense configurations that are as much about the intelligence as they are the optics.

The first thing it achieves, he said, is taking pictures in very low light (3-4 lux). A wider aperture can be used without introducing more lens elements.

The second trick is getting rid of the autofocus actuator, mimicking autofocus in software. Even with no moving parts, the lens can still autofocus via software.
