Shooting at Preset Focal Lengths (Step Zoom)
You	can	shoot	at	preset	focal	lengths	of	28,	35,	50,	85,	100	or	140	mm	(35mm	film	equivalent).	This	is	convenient	when	you	want	to	shoot	at	the	angle	of	view	of	those	focal	lengths.
1	 Assign	[]	to	the		dial	
(=		168).
2	 Choose	a	focal	length.
zzTurn	the		dial	clockwise	until	it	clicks	to	change	the	focal	length	from	28	mm	to	35	mm.	Keep	turning	the		dial	to	increase	the	focal	length,	which	changes	to	50,	85,	100,	and	140	mm	at	each	click.
•	 Step	zoom	is	not	available	when	shooting	movies	even	if	you	turn	the		dial.
•	 When	using	the	digital	zoom	(=		63),	turning	the		dial	clockwise	will	not	change	the	zoom	factor.	However,	turning	the		dial	counterclockwise	will	set	the	focal	length	to	140	mm.

Shooting Close-ups (Macro)
To	restrict	the	focus	to	subjects	at	close	range,	set	the	camera	to	[e].	For	details	on	the	focusing	range,	see	“Specifications”	(=		303).
zzPress	the		button,	choose	[e]	(either	press	the		buttons	or	turn	the		dial),	and	then	press	the		button.
XXOnce	the	setting	is	complete,	[e]	is	displayed.
•	 If	the	flash	fires,	vignetting	may	occur.
•	 Be	careful	to	avoid	damaging	the	lens.
•	 To	prevent	camera	shake,	try	mounting	the	camera	on	a	tripod	and	shooting	with	the	camera	set	to	[[]	(=		65).

Shooting in Manual Focus Mode
When	focusing	is	not	possible	in	AF	mode,	use	manual	focus.	You	can	specify	the	general	focal	position	and	then	press	the	shutter	button	halfway	to	have	the	camera	determine	the	optimal	focal	position	near	the	position	you	specified.	For	details	on	the	focusing	range,	see	“Specifications”	(=		303).
1	 Choose	[f].
zzPress	the		button	and	choose	[f],	either	by	pressing	the		buttons	or	turning	the		dial.	Immediately	press	the		button.
XX[f]	and	the	MF	indicator	are	displayed.

	buttons	or	turn	the		dial	to	specify	the	general	focal	position,	and	then	press	the		button.
3	 Fine-tune	the	focus.
zzPress	the	shutter	button	halfway	to	have	the	camera	fine-tune	the	focal	position	(Safety	MF).
zzYou	can	also	fine-tune	the	focus	by	pressing	the		button.
•	 AF	frame	mode	or	size	cannot	be	changed	while	focusing	manually	(=		145).	If	you	want	to	change	the	AF	frame	mode	or	size,	cancel	manual	focus	mode	first.
•	 Focusing	is	possible	when	using	the	digital	zoom	(=		63)	or	digital	tele-converter	(=		144),	or	when	using	a	TV	as	a	display	(=		243),	but	the	magnified	display	will	not	appear.
•	 To	focus	more	accurately,	try	attaching	the	camera	to	a	tripod	to	stabilize	it.
•	 To	hide	the	magnified	display	area,	press	the		button	and	set	[MF-Point	Zoom]	on	the	[4]	tab	to	[Off]	(=		48).
•	 To	deactivate	automatic	focus	fine-tuning	when	the	shutter	button	is	pressed	halfway,	press	the		button	and	set	[Safety	MF]	on	the	[4]	tab	to	[Off]	(=		4 8 ).

Digital Tele-Converter
The	focal	length	of	the	lens	can	be	increased	by	approximately	1.5x	or	2.0x.	This	can	reduce	camera	shake	because	the	shutter	speed	is	faster	than	it	would	be	if	you	zoomed	(including	using	digital	zoom)	in	to	the	same	zoom	factor.
zzPress	the		button,	choose	[Digital	Zoom]	on	the	[4]	tab,	and	then	choose	the	desired	option	(=		48).
XXThe	view	is	enlarged	and	the	zoom	factor	is	displayed	on	the	screen.
•	 The	digital	tele-converter	cannot	be	used	with	digital	zoom	(=		63)	and	AF-point	zoom	(=		87).
•	 The	respective	focal	lengths	when	using	[1.5x]	and	[2.0x]	are	42.0	–	210.0	mm	and	56.0	–	280.0	mm	(35mm	film	equivalent).
•	 The	shutter	speed	may	be	equivalent	when	you	move	the	zoom	lever	all	the	way	toward		for	maximum	telephoto,	and	when	you	zoom	in	to	enlarge	the	subject	to	the	same	size	following	step	2	on	=		63.
