As I have difficulty adjusting the focus wheel on my enlarger with that same (right) hand, it means I have a lot of trouble using it.

    It would be great if it could be just placed on the easel, but it can't.

    If anyone knows of an adaptation that would allow one to use it "hands free", I'd love to hear of it.

    Well, I would try next: Melt some candles in let say small ashtray or anything with diameter for example 3 to 5 centimeters and let say 1 to 2 centimeters high. While candle wax is liquid put in it something, let say some metal parts, to make it heavier. Also while wax is not cold and stiff, that is while it is still soft, but not liquid and hot, put in center your Hocus Focus and try to hold it (or support it somehow) to be "perfectly" (as much as can) aligned. When wax is completely cold and stiff you will get as result your Hocus Focus fixed in wax base.

    In fact, as I have Hocus Focus too, I will try this

    Of course, if you can and know, or have someone to make for you real plastic or metal base for Hocus Focus, it would be better.

    Haris, use "Plasticine" then you have more flexibility.

    Yes, Ian, thank you, I thought on plasticine too.

    I mentioned wax as something easiest I can remember. If one can make base (process, melt and cool) for example of heavy rubber or anything it would work, of course. So, anyone, please feel free to adjust my idea to suits your needs

    From what you say I still wont be able to see the grain but with the Peak unit I can go and look for other details on the neg to concentrate on.

    There's a Peak 2000 for sale on e-bay U.K. right now at a "buy it now" price of £95. It's under "Enlarger Equipment". It's not new but the seller in Looe, Cornwall has a 100% record. I think he asking £8 for postage. Worth a look?

    As I understand it the Hocus Focus isn't actually a magnifying device or so the seller of one on e-bay says but is claimed to increase light intensity by about 3 stops. Again the sale price if I recall was less than Nova's but I can't recall if it was "buy it now" or an auction.

    Dave/Trevor, my line of thinking is:-
    If there is no grain to focus on as we are using 5x4 then focus on other details on the neg.
    The other details might not be in the centre of the picture - hence can you still see the corners of the photograph through the Peak device - as that might be where the details to focus are.
    I am not trying to check for lens/baseboard alignment or evenness of centre/edge lens focus just trying to maximise the focusing options.
    After all investing 100+ UK Pounds on a focus finder that doesn't cut-it or really offers no greater coverage performance would defiantly spoil my day

    Thanks Pentaxuser
    I have had a look and am tempted
    There are a few days to go on this one so I will have a think about it.
    At 95+8 postage he is hardly giving it away - its about 2/3rd the price of a new one.
    On the other hand its hardly going to wear out either.

    Hi Martin,

    I can certainly appreciate your concern.

    The Peak 2000 will certainly allow you to see into the corners. The Peak I use, the 2020 will not do this, but I find its ability to distinguish focused/out of focus grain, even 5x4 TMX 100 negs a great asset and has performed well for a number of years. One of my better investments. BTW I do focus with the lens wide open (5.6) or at most 1 stop down. I've never experienced a problem with focus shift if I do have to stop down for printing.

    If I were you I would seriously consider that Peak 2000, with care it will last you a lifetime and the lifetime whoever you leave it to

    Regards,
    Trevor.

    I believe Ctein amongst others has indicated that the blue filter is superfluous in practice.

    The Hocus Focus is simply a piece of bent plastic that uses a mirror to reflect the image from the negative on to a ground portion of the plastic. It does its job very well but is not a grain-focuser as such: even the heaviest grain will not show up on the ground section.

    Its brightness makes it ideal for LF work where, as has been pointed out, there is often little grain upon which to focus in any case. Although I have one, I tend to use my Paterson finders unless I have to focus a way off-centre in which case the Hocus Focus comes into its own. The Paterson finders (Major and Minor) do a perfectly good job and are adjusted for my eyesight so I don't have to search for my reading glasses in the dark...

    Bob.

    In a perfect world with perfectly aligned enlargers and perfectly flat negatives, this is certainly true. My world isn't perfect. An old Mitchell Unicolor focusing aid lets me check any part of the image for sharpness better than my old eyes can without help. In enlargers with alignment adjustments or provisions for perspective control, this is valuable.
