Lens choice for A900
« on: March 12, 2009, 05:49:35 PM »
Do you know why I don't want to buy an A900?
Because of the choice of lenses available.
Most of the Sony lenses are DT (made for small format sensor)
So you only have a limited choice for the Alpha 900
and that choice has a big price tag on it.
What do you think about that?

I thought that there was more FF lenses than there was DT lenses ??? almost double the amount ???

Unfotunately the higher the MP the camera's become, the more expensive the lenses get to make the most of the resolution. Though this is not always the case.

I think you need to look again.  MOST of the Sony lenses, not to mention the selection of Minolta lenses, are FULL FRAME.

My $400 Minolta 28-75 f/2.8 works very well on my A900, as does my $150 Minolta 70-210 f/4.  Yes, my more expensive 24-70 f/2.8 Zeiss and 70-200 G work better, but there are good FF lenses to be had a good prices.

Your 70-300G should work great on it.

I actually got mine for $330 New-In-Box.  =)

I got lucky and snagged it 2 years ago from Willoughby's.  Probably the last thing I will ever buy from them, but I lucked out on this one.

I was thinking about the new Sony lenses only,
like the CZ 16-80, you can't use it on tha a900,
also the 18-70, 18-200 and the 18-250.
The cz from around 1500 euro fit well.

On the 900 and being limited to the Sony lenses as you are planning. I like the 24-70 2.8.  The 16-80 to me anyway is overrated and for me mostly useless as I need the 2.8 for most of my work. I would take the older Minolta 28-75 2.8 instead.

Actually you can use DT lenses, but images are automatically cropped to 11MP (there's an APS-C mode)

I guess if you are looking at buying superzooms, the a900 will not be on your shopping list.  There is little point in using APS-C lenses on the a900, you are much better of buying 3rd party FF lenses.

And like most a900 owners, the 3rd party lenses will be stop gaps until they can buy the real deal (16-35,24-70,70-200 f2.8 SSM) or maybe the lens covers a focal length they don't require such high resolution.

There are lots of stop gaps BTW, and a lot of them perform very well.  Tamron 28-75 is a cracking lens on FF.  My KM 17-35 (same as Tam 17-35) also performs very well.  But put a top end lens on the a900 and it really does shine.

e.g..  took a test shot with the a900 + CZ2470.  This is the lens wide open at f2.8:

This is the full size image:

This is the cropped image:

Note that when looking at the a900 images at 100%, as most monitors display at 75dpi - the image size would be roughly (if I remember correctly) 1.5m x 1m

You're right about the CZ 16-80 - that came out well before the a900 and is DT. As Simon says you can still use it.

But the CZ 16-80 being DT is (a big part of) why the CZ24-70 was released - a full frame CZ zoom :D

To be honest, the 18-70 (kit lens) and the 18-250/200 are much lower end consumer lenses than the a900 - they're for different market and I wouldn't have thought too many people would want to get the 24zillion pixel FF a900 to use with a freebie kit lens or an all in one lens ??? Although the a900 is much cheaper than the equivalent models in the other brands, you'd expect to be using high end lenses with the high end camera (in my opinion)

For me, I'd get the CZ24-70 first, then get the a900 later on - I want the best possible lenses before I start pumping in those huge image files :D

That sounds like a plan fother ???

Thats exactly what i am doing at the moment, getting all the lenses i need before i go FF. Just two more to go now, though its not likely to be this year.

Didspeed, as others have pointed out, there are more full frame lenses than Sony DT lenses.

More importantly: this camera performs at its potential with the better, fast, prime lenses than even the best zoom lenses.

Don't bother with the a900 if you're going to use consumer level zooms.

I'd agree with Alan: there is really little sense in investing in A900 if you can't afford glass that lets you utilize camera's resolution. I think that you 'll get more for your money by buying a700 instead and using the rest of money on a good lens (CZ2470 for example).

My only problem with Sony is them screwing us on price and building them with less quality in the body of the lense (the glass is still fantastic).
Compare the Canon 70-200 2.8 to the Sony 70-200 2.8 in price???

Almost identical. Hence the screw job. Sony's should be 2-300 less with out the IS in the lens. We already paid for it when we bought the body. Instead they allign with the Nikon or Canon equivelent. Maybe some day they will get a clue.

I guess I would need a definition of a consumer lens as that confused me not seeing any "consumer lenses" suggested???

In direct response to (and quoting)

The 18-70 kit lens is certainly consumer end. I'd argue the super zooms are too. Certainly not in the a900 league.

Not sure how that's confusing.
