Sony Alpha 900

With regards to Full Frame offerings I have been downloading original files for the the D700 & 5D and thought they were kinda the holy grail re: IQ

After reading glowing reviews of the Sony on the LL site coupled with the 24-70 Zeiss lens I decided to see what the files looked like & how they fitted into "my" workflow.

Most files from the Sony have similar characteristics as Pentax i.e. exposes for the highlights.The Sony requires very little adjustment with re: contrast, saturation etc but requires quite a substantial amount of sharpening with an amount of detail rendering i.e blades of grass etc that I haven't quite seen before - crop ability is quite incredible.

Wow - to be quite honest the detail, tonality, color separation, dynamic range, too be quite honest I haven't really seen anything close in it's price range.

I think if anyone was looking for a landscape/portrait FF dslr - this dslr or the 850 should be top of the list.

Anybody else have opinions/experiences?

we had discussed it here before
https://www.pentaxforums.com/forums/off-brand-canon-nikon-etc-camera-talk/777...-ff-users.html

there have been a few PF members that have moved onto Sony
the amount of resolution and detail for the price is a great combination. i just wonder how long sony stays interested in the DSLR segment

Not a900, instead an a850 thread

Sony Full Frames seem to require Capture One for better image processing.

This guy mentions too much noise then states he is using iso 1600+! The light looks ok in the posted shots so why is he using such high iso? I would be using 100-200 max and have no noise. Maybe he hasnt heard of tripods??

i think probably to handhold the tele ... at least for the bird photos
with higher resolution sensors, they are also more acute to shake as well

Also in low light, motion blur would be a bigger concern and to keep shutter speed high, one just have to increase iso.

I really have never used Sony DSLR's so I don't have any experience with them. I would think that one of the biggest drawbacks is a lack of lenses isn't it? Compared to Canon and Nikon, the offerings are small. (Unless you go back and count old Minolta glass)

True, but B&H sells 125 Canon lenses. (and 121 Nikon) That was my point, that if one wanted to move into FF photography, I would think that Sony's limited lens selection would be a negative. If I were going FF, I would go with the Canon 5D MkII. $200 less than the Sony, and all that available Canon glass!

What about the old Minolta AF glass (from the 35mm Maxxum days)? Can these lenses be used on the new Sony bodies?

Yes Old Minolta AF lenses work on Sony too

Yes Old Minolta AF lenses work on Sony too. And Minolta pro lenses are far more abundant so they cost less on used market in comparision to Pentax.

Here's a link from a seller I do biz with in Japan and their recent Minolta at ebay lens sales. Note the 300mm 2.8 sold for $1,000 less than similar FA 300mm 2.8 Pentax sold at pentaxforums last month. FULLY $1,000 less and Sony has two full frames with inbody image stabilization to drive it:

and the direct link to 300mm 2.8 Minolta sale:

Certainly as a high resolution landscape camera (where you're using ISO 100 and fps don't matter) it seems like an excellent package for the money, it did cross my mind as a reasonable FF route for landscaping.

The only thing bothering me is the high ISO noise that's much talked about, deffo seems far behind the EOS 5D MK2 on that front.

CZ glass in Nikon and Canon mounts are highly coveted

CZ glass in Nikon and Canon mounts are highly coveted.

Sony full frame platforms offer inbody shake reduction too.

Sony current system has some serious pluses and some minuses too. There are more and abundant used lens choices than Pentax offers & Sony has NO plastic mount lenses either And I've yet to read about ANY lens motor failure in Sony glass thats so common with Pentax SDM.

Sensor noise is a drawback, but with right software its usable.

a850 at $2000 to start is compelling and many say its sold as a loss. I'm not sure that Sony subsidizing their full frame buyers thesedays is a bad thing? Kinda makes up for premium cost of pro caliber CZ Glass?

The CZ 24-70 2.8 is a tweeny bit more expensive than the N/C counterparts but has zero barrel/pincushion distortion & zero CA & vignetting at all apertures and FL's.
