Hah! I think, in such situations, it takes a lot of self-control not to treat the person saying these things with the utter disdain that one feels!

Not really want I went for (the forecast suggested the possibility of fog and a colourful sunrise) but still, not a bad 'blue' shot all the same.

CCD Advantage??

Overall, I find the 645Z (with its CMOS sensor) to be much more flexible and effective in use. The malleability of the files in post, the wonderful low noise, high ISO performance, live view, etc.. And, incidentally, all the other benefits the Z has over the D which have nothing to do with being CMOS over CCD (such as frame rate, etc.). I had to use bracketing and blending files (and/or grad filters) much more with the D than I do with the Z. I simply couldn't do my high ISO, quick frame rate astro stuff with the D.
But, despite that overall decision in favour of the Z, I do think the colour rendition of the D was slightly better in my subjective opinion, especially in the reds. I cannot get the Z files to look the same as a D file in its colours, even with lots of post-editing (which, of course, could be a result of my limitations as an editor). In the end, I accept the balance in favour of the Z and rarely look back. But if your style of shooting doesn't require the benefits of the Z, and you prefer the colours of the D, then it remains a very good option (if rather dated these days).

Thanks guys. Yes, it genuinely was a very rough time for them - it just didn't look it, with the big swell bypassing my foreground. So it somehow reflects the mood of the morning better with this wilder foreground, even if it was taken in July!

Rear mount filters for Arsat 30 fisheye lens
Posted By Ed Hurst

Good points - and it would be good to know. Not just for this lens, but for others that have a rear-mount or drop-in filter (with the intention that it's used normally with a plain glass filter in there). For example, the Pentax 25mm DA or DFA lenses. I suspect, in the case of the Arsat fish-eye, that you'd be hard pressed to see any issues as long as you're focused properly, just because the lens is bound to have some uncorrected imperfections anyway, but - as you say - it would be great to know for sure :-)

Of course, if you focus with magnified live view, then you will automatically be adjusting anyway for any differences in refractive index (with a margin of error, that would probably apply anyway).

Thank you! It's really a product of a few things:
- Shooting through rainy weather on a long lens
- Sea spray in the air
- The sun rising in the background, leading not just to backlighting/silhouetting but also a softness of colour through the rain/spray
- Maybe something about the compression of perspective on the long lens as well, making it seem real but unreal!

Weird question re. 645 and 67 mount adaptation
Posted By Ed Hurst

I have already the 67 400mm f4 EDIF, 67 1.4x and 2x teleconverters and the 645 1.4x and 600mm f5.6 lens. So have been able to make some of those comparisons, Theuns.

For me, the 2x converter (while "ok" in quality) doesn't make sense to use. I find using the 1.4x and then up-rezzing the resultant file is actually superior. It seems that the 1.4x converter is the sweet spot and once you get to 2x, it loses more than it gains.

So, in practice, that means for me that the 400mm f4 with 1.4x converter (which gives 560mm) is a good option. Once I want more than that, the 600 (with and without the 1.4x) comes into play. There isn't much difference in quality between the 400mm with 67 1.4x converter and the unconverted 645 600mm lens. But the 645 with1.4x converter is better than the 400mm with the 67 2x converter. BUT because I know the 67 1.4x is better than the 645 1.4x converter, I wish I could use it with the 645 600mm lens!

If I got the 800mm lens, I wouldn't use it often. But I do find a surprising number of situations in which the 645 600mm with 1.4x just isn't enough. So it would be a nice one to have. It will have to wait though, as I cannot afford any major purchases for the foreseeable future!

I've been eyeing that 67 800mm EDIF lens for years, but not in a position to make such a purchase at the moment! Wish I were...

Of course, with that lens in hand, it can be used with its dedicated 1.4x converter and get something even longer...

Yes, that's the one. I hadn't ever heard of it until Mike kindly shared it with me. I had previously tried to use more complex rigs to support big lenses. Three points of contact, etc.. Or two tripods. They work well but they take lots of patience to set-up and can be maddening in use if you're having to move the camera around to shoot. This method is much more flexible. As Mike says, the monopod not tightened but just making loose contact with the ground seems to be enough to minimise the vibration.

Good luck with it, Paul. Hope it works for you and is also safe for everyone concerned!

At present, I use both of those set-ups. I also use the 1.4 645 TC on 645 lenses (which, of course, requires no adaptors).

But I am looking to do the following:

C) Native 645 lens -> 645/6x7 adaptor -> 1.4 6x7 TC -> 6x7/645 adaptor -> 645Z/D body

Hello all,

I know this is a very weird question and I am pretty sure that the answer will be 'no such thing exists without creating it as a custom build just for you'!

I make use of the 645 1.4x converter with the 645 600mm f5.6 A lens. I also have the 67 1.4x converter, which I have used with the 67 400mm f4 EDIF lens (amongst others). I have the impression that the 67 converter is optically superior (though I can't prove it) - this is based on usage in cases where I can use either converter (i.e. when using converters with 67 lenses on the 645Z/D). I wish I could use the 67 1.4x converter with the 645 600mm lens. But that would involve having a mount adaptor that works in the opposite direction to the usual - in other words, converting the lens mount UP in size rather than down, so that I can mount a 645 lens on a 67 1.4 converter (which, of course, is then converted back down in size to be mounted on the 645Z/D). I am guessing, since there wouldn't be much call for such a device, that it doesn't exist. Unless someone knows better......?

Ed

Thanks mate - really appreciate it :-)
P.S. I still think of it as 'the Datsun'. Showing my age...




Hey Paul. Yes, it's seen a lot of use over the years, and I have never 'babied' my equipment. Hope you're still able to get out a little bit at the moment...





That's so kind of you, Theuns. Likewise right back at ya!




My 'behind the scenes' shots are with my mobile 'phone too. Just regular Samsung shots...





Mike - notice that this was the first time I put into practice your tip of using a monopod for further stabilisation when shooting with the 600mm. Much simpler than the other big lens rigs I have dabbled with and highly effective. Thank you! :lol:
