Hey there!

I'm utilizing boards like this to make a decision on which camera to purchase eventually, and I appreciate everyone's honesty thus far about their respective cameras.

Question for XH-A1 users:

Can you get the same amount of latitude from an A1 as you can from a V1U?

Yes. No matter what the marketing bumph from Sony says, the actual latitude is very similar. The A1 has a very healthy dynamic range for a prosumer camcorder.

Hey there!

Question for XH-A1 users:

Can you get the same amount of latitude from an A1 as you can from a V1U?

The A1 has IMHO no more than one full stop less of latitude than a properly adjusted V1. Have done comparisons of both with the very same scenes. This might be attributeable not just to the EIP, but also the more agrressive low knee setting on the V1.

The A1 has IMHO no more than one full stop less of latitude than the properly adjusted V1. Have done comparisons of both of the very same scenes.

Adam Wilt, who tested the A1 and the V1, seems to have come to a similar conclusion:

8.3 Stops for the A1
8.3-9 Stops for the V1

Adam said that in his tests pictures shot at the same time with the Z1, V1, XH-A1, and HVX200 all handle highlights in a very similar way. Out of the cameras the V1 was about a stop slower than the A1, with the HVX200 being the fastest in terms of low-light.

The review of the V1 is here http://www.dv.com/reviews/reviews_item.php?articleId=196602843 and the A1 here http://www.dv.com/reviews/reviews_item.php?articleId=196602584

Am I confused? Piotr said; A1 has 1 stop less latitude. Adam Wilt says; V1 is 1 stop slower.

So Piotr, you don't agree with Adam Wilt? Or have I read it wrong?

The V1 is slower (is less sensitive in low light) but has a wider dynamic range (from dark to bright without losing the highlights).

So right now this is what it's looking like:

HVR-V1U PROS:
True Progressive CMOS
Wider Latitude

HVR-V1U CONS:
Rolling shutter effect on fast moving images
Performance suffers severely in low-light (as per Adam Wilt review)
No video output (w/o special cabling)

XH-A1 PROS:
More customizable controls for imaging
No rolling shutter
Near full-res 24f mode (with CCDs that are higher rez than the Sony's to begin with)
Better low-light performance

XH-A1 CONS:
More apparent CA (chromic aberration) especially on the wide angle



That CA really does worry me.

In fact the actual amount of CA is comperable on both cameras under similar lighting condition BUT for some reason it sticks out like a sore thumb on the A1!

There is certainly more noticable fringing on the V1 than the Z1/FX1. And it's more noticable on the Z1 than the HVX200.

Just be thankful that you're not looking at a JVC GY-HD100 with an early lens!

Is the CA really terrible? Sore thumb sounds disheartening...

It's like I have to choose between high resolution without rolling shutter but with noticeable CA, true progressive with rolling shutter and still noticeable CA (though less), or stick with my HVR-Z1U with less resolution in CF25 mode but no visible CA!

Aack!

Maybe I should wait until the next generation pops up. :(

Am I confused? Piotr said; A1 has 1 stop less latitude. Adam Wilt says; V1 is 1 stop slower.

So Piotr, you don't agree with Adam Wilt? Or have I read it wrong?

Simon, I said the A1's latitude is "no more than a stop less" which translates to "almost one stop less" than V1's, which is the same as Adam and Alex's observations. Sorry for my English:)

That CA really does worry me.

I was more worried with ergonomics (great, but inferior to V1's) and the build quality (again less solid than that of the V1). But this is just me; both are great cameras.

The CA isn't terrible. Most of the time you don't see it at all. But when it's there it's REALLY there. It comes across as a much more "vibrant" outline than any other camera I've seen.

It bugs me probably just as much as rolling shutter would (ie. it's a fairly infrequent annoyance).

PS. Piotr - I think your English is excellent! From the way you write I would have no idea that it wasn't your native tongue.

I don't see the CA on most things I shoot, which are mostly people, scenes with actors, etc. It's on most all cameras except much more expensive ones. In fact, it's worse on the DSR500, which has a $15K lens.

I've not seen CA on my HVR-Z1U, so I've obviously never shot in an environment that is treacherous to this camera in that regard (actors, interviews, good lighting, bad lighting, in door, outdoor, zoomed in, wide, etc).

Question for A1 users: what environments where you shooting in that aggravated the CA? This is a major obstacle keeping me from pursuing the A1 at the moment and would like to know, unlearned as I am in this regard, what situations cause the CA in general.

Piotr - your English is fine, it's my eyes and brain at this time of night. For some reason I was only thinking of the highlight end and not the black end.

I've not seen CA on my stuff. The clips I've seen it in are more contrasty and 'simple', e.g. branches against a bright sky. Personally I don't think it's bad enough to put some off the moving picture - if you're watching the content rather than the image you'll never see it (IMHO).

In my line of work with the camera we require a lot of still frames with the footage and I take aprox 1 frame for every 15 secs of footage and have had no noticeable CA problems as of yet. My stuff is mainly people indoors. We have found the quality so good we have been able to do away with a still photographer in a lot of instances.

Thanks everyone for your honesty and opinions -- however, I just learned of the new XDCAM EX for under $8k that's coming out this fall. This will be the unit I will wait for.

This is a wonderful community, and I value it greatly!

The XDCAM-EX does, indeed, look to be very cool. But in addition to the $8K you have to buy the Sandisk cards. No doubt they'll be cheaper than P2, but even so to get enough for serious documentary work or extended shooting, my guess is it's going to cost a couple thousand more. And then you'd want their very cool portable XDCAM HD burner so you can archive your footage to XDCAM discs, which is an excellent solution to the solid state tapeless workflow problem. So by the time you get the system, it's probably going to be over $12K instead of under $8K. However, it's a 1/2" chip XDCAM HD camera comparable in quality to the F-350. It really isn't in the same category as cameras like the XH A1 and Sony Z1, etc. It's more of an XDCAM HD "B" camera. I think it's going to be awesome, but a different animal.

True, but all said and done, I think it better to save $3k I would spend on an XH-A1 now and save for a camera that'll be out this fall (I won't buy till next year) that is closer to what I've been looking for.

My HVR-Z1U will tide me over in the meantime.

Thanks.

Brandon, if you currently own a Z1, you will absolutely do the right thing waiting for the new generation cam rather than replacing it with either the V1 or A1! I'd do just that if I were you.
