tinnews@isbd.co.uk - 06 Nov 2007 10:45 GMT
I'm looking at buying a new digital camera in the (hopefully/probably)
sub £200, or maybe around £200 sort of price range.

It can be either a 'point and shoot' or maybe (and this is where I'm
looking hardest) one of the cameras like the Fuji S5700 and S6500.

Apart from straightforward specifications which are fairly 'universal'
and easy to compare I have a few criteria which are very difficult to
find any information about:-

   I'd like the wide angle end to be wider than "35mm equivalent", I
   found that my 28mm lens on my old OM2 was my most heavily used
   lens.  One of the Fujis (I think it's the S6500) goes to 28mm
   equivalent, are there any other cameras offering this wide a lens
   in the same sort of price category?

   I want reasonable speed of operation, both for 'ready from turn on'
   and 'time to take a picture after pressing the button', our
   present Olympus C460 is rather poor on this front.  Is there
   anywhere where one can find comparative 'speed of operating'
   information for digital cameras?  And/or can anyone recommend
   cameras/makers which are good from this point of view?

Thanks for any help and advice, just comments/reports about particular
cameras would be useful.

I'm not quite sure what you're saying here - "35mm equivalent" isn't a
focal length, it just means that the lengths quoted alongside it are
expressed as if the camera had a 24x36mm image sensor (because everyone
knows what a 28mm lens or a 200mm lens is like in 35mm terms).

Well no one actually quotes focal lengths for digital cameras, they
quote "35mm equivalent", i.e. they give the focal length which would
give the same angle of view for a standard 35mm camera that takes
24x36 pictures.

I used my 28mm (really 28mm that is) wide angle lens on my OM-2 a lot
so I'm looking for a "28mm equivalent" wide angle on a digital camera
which, as I understand it, will give me the same angle of view.

Ah, sorry, I see what's confused you, by "35mm equivalent" I meant
a focal length of 35mm, it's just confusing that the wide angle end
of many (most?) digital camera zoom lenses happens to be the
equivalent of a 35mm focal length lens on a camera that takes 35mm
film.  That 35mm occurs twice is just coincidental (and confusing!).

I think the S6500 is the only long zoom (300mm equiv) camera with a 28mm
equiv wide end in your price range.  If you can live without any form
of viewfinder, just using the LCD on the back, and somewhat less zoom
range, then I think some of the Ricoh R series or some of the Canon Ixus
might suit you.

Most non-DSLRs are pretty poor in this regard, though the Fuji S6500 is
better than many.  The reviews here http://www.dpreview.com/reviews/
generally give fairly detailed information on various timings.

If low light action shots might be of interest, the Fuji S6500 is
probably the best available, short of a DSLR.  It has rather less noise
at high ISO sensitivities, which enables faster shutter speeds in low
light.

Check out the Panasonic FZ18 - that has a wider range - but is currently
(it's fairly new) slightly above your price range. I've been very
satisfied with an earlier model (FZ5) for which I have a w/a adapter.

OK, thank you, I can find it at £239.99 so it's not impossible.

Its Probably the best in the range I got a 9600 to replace my Minolta 7Hi
and wanted 28mm too
The only others with a 28 eqv are the more compact but smaller sensor and
not quiet up to bridge/crossover standards the 6500 and 9600 have the fell
of a slr complete with hand control on the lens( not one the pops in and out
of the body) even a proper cable release.

Almost any of the many Panasonic Lumix models or Ricog Caplio models have
28mm at the wide end. The price though is they're usually 105mm at the long
end, except Ricoh Caplio R5/R6 etc which are 28-200mm.

Elsewhere though you said you needed optical viewfinder, this limits you a
lot, none of the small Panasonic or Ricohs in your price range have a
viewfinder.

For shutter lag table see
http://www.cameras.co.uk/html/shutter-lag-comparisons.cfm

You can also glean timing info from individual reviews at
http://www.dpreview.com/reviews/

Note though that like a lot of sites the first one doesn't mention Ricoh
products (and dpreview mentions them only rarely) due to them not being
sold in the USA (for some mysterious reason that no-one can fathom). A site
which *does* happily review Ricohs is
http://www.photographyblog.com/reviews.php
but it doesn't seem to have any precise timing info.

It's worth checking more than one review before making a purchase I think.

Quite, dpreview is quite complimentary about the S6500FD but it would
be nice to see some other reviews.  Its worst point seems to be the
viewfinder, maybe I should try and find one to look through before I
buy it.

If its any use I've recently bought a Fuji Finepix S5800 which is fine
for the Zoom lens and anti shake etc, but its a bit of a job to get
decent images from it the reason being that under most all conditions it
shoots at 800 ISO which is way too fast.

You can faff around putting it into a manual mode where you can get that
down to lower speeds but overall I bought this to replace a damaged E550
and the Pix from that are still that bit cleaner and sharper..

The ones thus far produced on the 5800 seen to be either "dirty" or
"noisy" and lack definition. However it seems that a lot of cameras are
like this nowadays..

OTOH for the money and if you need the Zoom which I find useful then I
suppose its quite good value for the money around £115 plus VAT from e-
buyer...

I doesn't move the sensor on my 9600 Just sets higher iso as needed to allow
higher shutter speed

A lot of cameras do both. Mine has CCD shift stabilisation but if Auto
ISO is enabled then it also gradually raises the ISO if the shutter
speed falls below about 1/30 sec.

Personal experience is that Ricoh are one of the fastest in terms of
shutter lag - a tad slower than Casio and a touch quicker than Canon.
<Anything> is quicker than an older Olympus or Nikon!

In my Caplio RR30 handbook it actually specifies a press-to-picture time
of better than 220mS!

Which is a load of technobabble. As we've discussed here before, shutter
lag is a combination of
       Viewfinder delay
       Focussing delay
       Exposure assessment delay
       Physical trigger delay
       and in this case - storage to memory delay. (multiple exposures)

The last and the focussing delay are usually the worst, and can be
bucked by using manual focussing. Exposure assessment delay (usually <.1
sec) can be bucked by using manual or preset exposure.

Viewfinder delay can be bucked by using your eyes...

So don't accept just one figure as being good or bad...

>You can also glean timing info from individual reviews at

Which analyses much of the above.

Following your posting and the responses to my query, I have tried
looking for some way of doing manual focussing on the sort of camera
I am interested in.  And failed.

It seems that manual focussing comes on the relatively large and
heavy (and definitely expensive and complicated) cameras only, and
that some blurbs call a special focussing menu "manual focussing".
Well, for real action shots, you need to be able to set up the
camera by touch alone while watching for the moment - and then snap
and shoot in a fraction of a second.

I went into a local shop, and they told me that I could get fast
times on the DSLRs, because they have more powerful motors.  Large,
heavy and expensive, again :-(

Have I misunderstood this, and am I looking for something that is
no longer possible?

Nick Maclaren.

Fast times on dSLRs because they have more powerful motors? Rubbish.
Maybe you will get shorter times between frames in multi-shot (motor
drive) mode, but the shutter lag is nothing to do with motors.

Some compact cameras have significantly less shutter lag than others.
Casio and probably Ricoh are two of the fastest, with Canon and Sony
pretty close behind. The slowest traditionally are Nikon and Olympus.

You can prefocus and pre-expose on most compact cameras by pressing and
holding the shutter half way, then when you press it the rest of the way
down it will take the picture almost instantly.

If you are after fast action shots forget a compact, they just won't do
it. A dSLR is the only answer there - and they are not really that
complicated once you get used to them. As they are all auto everything
you can use it just as you would a compact, albeit agreed they are
larger and heavier.

How is focussing done on those things?  If it involves physically
moving the lens, I can see that as a possibility.  The other obvious
one is the power of the CPU.

Shutter lag, per se, hasn't been a problem in an awfully long time,
though I have used a camera where it was ....

Thanks.  Yes, I had heard that.

Pre-expose, yes, but what you are about to shoot isn't necessarily
there in advance of you shooting it, so pre-focussing isn't always
feasible.  It also involves taking your eye off the ball, or shooting
from the hip.

I am sure that some cameras are better, but my wife's Olympus mju was
almost impossible to use like that, as I couldn't tell when it was
exactly half way by touch alone.

So why do Canon, Nikon, Olympus and Sigma invest tens of millions in
developing ever faster, quieter and more powerful motors to focus
their SLR lenses faster?

It isn't "rubbish" at all.  DSLR manufacturers compete to offer the
fastest and most accurate focusing systems because that is what DSLR
buyers demand.

To the original poster, one of the fastest focusing DSLRs is also one
of the cheapest.  It is the entry-level Nikon D40X which has a 10
megapixel sensor.

To keep costs low, the D40X only offers autofocus with Nikon's AF-S
series of lenses with the "Silent Wave" ultrasonic focusing motor. The
plus side of that is that all these lenses have extremely fast and
accurate focusing.

I think you were either reading out of contect or you hadn't seen all of
my original post.

The salesperson in the shop stated that dSLRs are faster <than compacts>
because they have more powerful motors. Any dSLR will focus more quickly
than almost any compact because of the way they work.

In the context that you read it - as dSLR versus dSLR - you are right
and I won't argue with you, but in the context of dSLR versus compact I
stand by my original statement.

But manual focusing on most DSLRs is a joke.  It's only recently that
you have been able to get DSLRs with interchangeable screens, so at
least now in 2 or 3 models you can get a proper split-image viewfinder
to get exact manual focus.  Until now you had to put up with viewfinder
focusing screens that were straight from the 1950s, and if you
complained you were given the immortal line: 'Manual focusing?  No call
for it mate'.

I would guess that this is an example of shop assistants wool-pulling!
Although it's true that a large lens will need a larger motor to shift its
components, the result ought to be a draw.

On the other hand I find that having autofocus helps with my poor eyesight
through the viewfinder, so long as I have time to wait for the hunting to
and fro of the servo. But the amount of movement of the lens from max to min
is so small (to help the motor, no doubt) that manual focus is very tricky.
I wondered if a lever would help but it would be in the way and would have
to be balanced somehow. A vernier is what is needed.

I hope that modern DLSRs (which I have yet to get) are better at focusing
because they know in which direction to adjust and therefore do not hunt
from max to min while my quarry goes out of sight...

Mike.

My Nikon 8800 has "manual" focus.  It is still not manual in that it is
electronic via pressing buttons.  Whatever happened to the focus ring,
aperture ring and zoom all together on the lenses of my old Practic slr?  
And three types of focus aid in the viewfinder?

Most Ricoh compacts have manual focussing, but IME trying to focus via an
LCD screen is a slow and painstaking process, especially given the depth of
field of a compact camera. Mine does have an on-screen focussing scale, but
the markings go 1m - 3m - infinity, maybe that's sufficient with a
wideangle lens but you are very reliant on depth of field which you can't
really assess until after you've taken the shot, since the 2x focus
magnifier is pretty much useless.

To set focus up by touch you need a lens with a focussing ring I think, I
don't know if even any DSLR lenses give you that, let alone digital
compacts.

What you can do with some cameras is set them up for hyperfocal distance or
infinity. The Ricoh's give you those options. Some other makes of camera
offer infinity via landscape scene mode (though my Panasonic didn't, making
its landscape mode totally pointless).

I think SLRs achieve the zero lag you want by using predictive focussing, I
think this is pretty vital for action shots like sports, where autofocus is
otherwise always going to be a step behind the action.

Its landscape is optimised for photographing bottle gardens? :-)

That makes sense.  And it will sometimes get it spectacularly wrong,
like all forms of prediction ....

OK, I've had four digicams. The two had a manual button for focussing as
well as an autofocus mode (the others had genuine manual focussing (i.e.
turn a ring).

I switch them to the non-auto focus mode. Then for, say, street
shooting, I do what I always did with my Leica M3, and other film
cameras.

... which is to preset the focus by aiming at something between 3-5m
ahead, and wait for the action. Lift the camera (which is *on*) and
allow the exposure to be calculated as I fire the shutter.

If it's kids at 2m then prefocus there. That's all. It works!

If the subject is outside that range, then I may have to refocus (push
button again) and risk missing the shot. Although I could use the
rangefinder pretty fast, there were still shots I missed for the same
reason.

Oh, and to avoid camera delay due to viewfinder, use *both* eyes - one
on the subject, one on the viewfinder.  I was fortunate - I was taught
to do that in my biology lessons at school - one eye through the
microscope, one eye on the paper where I'm drawing what I see!

I'll have another go, but I couldn't use the button precisely enough
for such shots with the Olympus mju.  Other cameras may be better,
but holding it half down just isn't on - the focus would have to be
sticky for at least several minutes.

I can't do that - and I mean I REALLY can't do that.

No - I agree unless there is a separate focus button, rather than
half-press, the above won't work. (As I intend!)

Oh, sorry.

Some cameras do offer a proper focus lock separate to the half-press. For
instance my Panasonic FX01's underwater mode lets you lock the focus which
will then stay locked for all shots until you release it. Why this is only
available in "underwater mode" I don't know, and it means you later have to
undo its attempt to "correct" underwater blues!

One useful thing about the manual focussing on the Ricohs is that it
also serves as a focus lock - if you autofocus and then swith to manual,
the focus remains where it was autofocussed until you manually change it,
thus you can hold focus for as long as you like. This is true of the GX100
anyhow, and I assume it's also true of the R6 etc since they seem to offer
identical features.

Look at the D40 or D40x. Small and light and the AF-S lenses give you
the best of both worlds -- fast autofocus easily manually overridden.
Relatively cheap and uncomplicated too.
