I saw Willoughby's has the Sony 75-300 f4.5-5.6 dt Carl Zeiss as a buy it now fro $239.00. I would be interested in knowing more about this lens. I have a Quantaray 75 300 that I bought 10 years ago. It does not focus sharply at the 300 range. I've seen the same lens on ebay for nickles and dimes. That i probalbe why it doesn't focus well at 300. Just a junk lens.

Sorry, that' s not a Carl Zeiss lens, and you can buy the same lens directly from Sony for $229.99. ;-)

Sony 75-300mm- f/4.5-5.6 Lens at sonystyle.com for $229.99

You can find it for less sometimes elsewhere.

It's likely a Sigma (they made a lot of the Wolf/Ritz lenses sold under the Quantaray brand). Sigma's newer 70-300mm 70-300mm f/4-5.6 APO DG Macro (around $239) is about as good as you'll do in a consumer grade lens. All of these inexpensive lenses (Sony, Sigma, Tamron) tend to be a bit softer on their long end and require stopping down the aperture a bit for best results.

If you want better quality, I'd probably look at a used Minolta 100-300mm f/4.5-5.6 APO Autofocus Lens. They're available for around $300 used, depending on the exact model (for example, D versus non-D). Make sure to get one of the APO versions if you get a Minolta 100-300mm lens. The non-APO versions of them are cheaper for a reason. keh.com usually has some of them in stock. Here are some examples:

Minolta 100-300mm f/4.5-5.6 APO lens listings with hood and caps

You'll find more listings for them there, too.

P.S.

Sony does have a new G series lens in that focal range (still not a Carl Zeiss, but the G designation is reserved for higher quality lenses). It's also got SSM (Supersonic Motor Focusing).

Sony 70-300mm f4.5-5.6G SSM lens at sonystyle.com for $799.99

It's not in stock right now. But, they've been shipping in limited quantities. So, it should start to showing up at more vendors soon.

... and it's not a 'dt' lens either.

The good news is that 'Willoughby's' got the brand, focal length and aperture correct. :-)

I don't think the new 70-200/2.8 will be a CZ or even a replacement for the G.

I think it will be a rebranded version of the new Tamron (seehttp://www.tamron.com/lenses/prod/70200_di.asp ).

Tamron already makes a number of lenses for Sony ( 18-250, 18-200, 11-18 )and for KM before them.

I found a 100 300 apo on ebay. The guy said it would work on my K/M 5D. Well, it won't focus more than a few feet away. What is the button on the side of the lens for. I have pushed the button hoping that my problem would go away? Also, on the back of the lens, its rectangular. Before I start too much of a stir on ebay I want to see if the problem is on my end.



Thanks

It's closest focus distance should be almost 5 feet, which gives it a maximum magnification of 1:4 at 300mm (you are able to fill the frame with a subject 4 times the size of the film or sensor, which is common for zoom lenses with macro in their description). It's closest focus distance is 150 cm

Most people are not going to buy a lens that long for use at closer focus distances. It's a longer telephoto lens designed to bring distance subjects in closer so that they fill a greater percentage the frame. ;-)

The button on the lens is a focus hold button. That allows you to focus as desired, then keep that same focus distance by depressing the button so that the camera's AF system is disengaged.

Here are some specifications for the Minolta 100-300mm f/4.5-5.6 APO lens, with links to user reviews:

For example, the Sony 75-300mm f/4.5-5.6 you were looking at has exactly the same minimum focus distance (4 feet, 11 inches, or 1.5 meters), with the same 1:4 Macro ability. This is common with a telephoto zoom like this one reaching out to 300mm, and it's not the type of lens someone would normally use for closer subjects.
