Fujifilm X-Pro1 – My best camera yet!

I had been uninspired for the longest time, which to some extent explains the lack of updates here in recent months.

Sometimes, it really does take a new toy to reignite your passion for a hobby.

For me, it’s the Fujifilm X-Pro1 – a camera I had long considered out of my budget (despite my spendthrift tendencies), and with a sluggish AF, didn’t seem to worth the money. But it came into my radar again after I read that the latest firmware version has raised the AF speed to more acceptable levels.

Given that film was getting way too expensive to use, and that I felt the Ricoh GXR system has offered little to look forward to with no new lenses in the horizon, I decided to sell off all my existing camera gear on the local online photography forum Clubsnap to fund my transition to Fujifilm.

And I am so glad I did.

READY FOR PRIMETIME: My fully accessorised Fujifilm X-Pro1.

 

I chose the 18mm f2 and 60mm f2.4 to replicate my favourite lenses in my Nikon/Ricoh setup. The image quality of the 60mm is just stellar, and I daresay it rivals my Zeiss ZF 100mm f2 Makro-Planar. I intend to use it mainly for portraits, street photography and flowers, just as I did with my first “pro” lens, the Nikon AFS Micro-Nikkor 60mm f2.8. The 18mm, being wider, is great for general photography, and it's quite compact too. It's not as sharp as the 60mm, but sharpness isn't everything.

Well, I couldn't just stop there – the X-Pro1 is such a gorgeous camera and it deserves the right accessories to bring out its best. After endless hours of research online and a trip to the usual camera shops in Singapore, I finally managed to put together my ideal set of accessories for the camera.

Hello, Pinkberry!

It’s always difficult choosing a birthday present, and for the girlfriend it can be doubly hard, especially when you want to top your effort in the previous year.

Since Joanne’s two-year-old Samsung smartphone was dying on her, a mobile phone seemed like a good choice. After a somewhat extensive survey of the phones that come with keyboards (getting rarer by the day), I settled on the Blackberry Torch.

Is that a Blackberry?

Finally, an evolution

Ever since the D40X (released 2007), the lowest end DSLR from Nikon appears to have used the same 10 megapixel CCD sensor inherited from the D200 (released 2005). While the D60 (2008) and then the D3000  (2009) have sold very well, I could not help but feel disappointed at Nikon's lack of innovation in this sector of the market. 

Because the relatively poor ISO performance of the D40X is the main reason why I've been wanting to upgrade the cam since last year.

Can't really blame them I suppose, but it meant I had little incentive to upgrade from my D40X, which of course remains an outstanding camera after more than 300,000 pictures and lots of physical abuse: lots of rain, some snow, the seaside and once, a drop from about 1 metre.

But things seemed to have finally taken a turn for the better last week. Nikon announced the D3100, successor to the D3000. It will come with 14 megapixels with a base ISO range of 100 to 3200, which can further be boosted to 12800. It is also the first Nikon DSLR to do full HD video recording.

That's better than Nikon's top-end D300s DX format camera, at least on paper!

And for me, one of the most welcome innovation (for Nikon's bottom-end model) besides the brand-new sensor is a physical switch to toggle between Single frame shooting, Continuous shooting and Self-timer. The last option is the Quiet shutter mode. In the D40X/60/3000 as well as the D5000, these options can only be chosen from a menu on the camera's display. Because the camera automatically switches back to normal shooting mode (Single or Continuous) after a Self-timer shot, it was troublesome to do self or group portraits or long exposure shots without a remote, as one will have to change the setting through the onscreen menu to Self-timer again after every attempted shot.

But upon reading the specs a little more closely, I found a deal-breaker. Sort of. The D3100 doesn't work with the cheap Nikon ML-L3 remote, almost an essential accessory for my D40X for the past three years! I suppose the new shooting mode switch makes up for this deficiency to some extent, but that's quite a bummer, really. Shall have to await the D90 replacement, set to be announced in September, to see if there is a better alternative.

Besides compatibility with the ML-L3, I am watching out for two memory card slots. One memory card failure was all I needed to feel the need for this feature, which allows for instant back-up of pictures taken on a second SD card.

In the meantime, the Ricoh GXR is looking to be a very interesting (but relatively expensive) option.

A Quick Guide to choosing a new laptop processor

I decided to buy a new laptop a few weeks ago, after using my IBM Thinkpad X41 for the past 5 years. Boy did the little machine last me long! Last year, I maxed out the RAM to 2GB (from 1.5GB), bought a new battery and even tried to install a solid state drive (SSD) -- which unfortunately didn't work for some reason. Anyhow, I managed to get by for another year, and probably can continue using it for years if I didn't need a more powerful machine for photo editing.

Yep, for normal uses like web surfing and word processing the X41 still worked perfectly. But after editing photos on it for two years, using Nikon's power hungry Capture NX 2 software, I thought it was time to be more efficient. A new laptop was the only way.

Unfortunately, the CPU landscape has changed quite drastically since 2005. The latest CPUs have funky names like i3, i5 and i7... and now there are things called quad core processors. (My X41 has a single core Pentium M 1.5GHz processor.) For those who are as lost as I was when I started doing my research, here's a concise guide to choosing what you need.


The 3, 5, 7's of Intel's processors

Suffixes
  1. The new processors are generally called iX-XX0M. The suffix "M" tells you that it's a mobile processor. "QM" means quad core processor, and they only appear in the i7 line. "LM" means low voltage, while "UM" means ultra low voltage. The latter two sacrifice performance for lower power consumption and are thus meant for laptops that are lighter and/or tend to run longer on batteries.
  2. Intel calls its top end processors the "extreme editions" and they end in "XM".
  3. Then there is "E", which means it supports a special type of memory called Error Correction Code memory. Irrelevant for most of us. (There are also "LE" and "UE"variants.)

Other terminology
  1. The clock speed of the processor is the one of the main factors for its speed. They are written as XXX GHz. Bigger number, better.
  2. Except for 4 options in the i7 line, all of Intel's latest laptop processors are dual core. From what I have read, they are mostly faster than the corresponding models in the previous "Core 2 Duo" line.

i3 vs i5 vs i7
  1. The lowest end laptops with Intel's i3 processor start at higher clock speeds of >2GHz, except for the ultra low voltage version. The main difference is that unlike the i5 and i7 models, they don't have a feature to "turbo boost" their processing power. Despite that, they are fast enough for most typical business type uses.
  2. The i5 is the mid-range line. But there is an anomaly. Some of the i5 "M" processors are actually faster than the i7 "LM" and "UM" processors. The fastest i5 is the i5-540M.
  3. The top-end i7 line starts with some dual core options. The fastest is the i7-620M.
  4. Also of note are the i7-620LM and i7-640LM variants, which are slower than the i5-540M but consume less power, as mentioned earlier.
  5. There are 6 quad core options in the top-end i7 line: i7-720QM, i7-740QM, i7-820QM, i7-840QM, i7-920XM and i7-940XM. They are all power-hungry and laptops that use them are very bulky and tend to last less than 3 hours on a full battery.
  6. Another anomaly: the i7-620M is said to run faster than the i7-720QM when it comes to certain types of programmes, even though the latter has 4 cores to the former's 2. This is probably because the i7-620M has a faster clock speed, which probably matters more to most computer programmes on the market now. This means that the i7-620M is probably better value for money.

So how to choose?
Gamers and those looking for a mobile workstation:
i7-820QM and above. Be warned that these machines are expensive, quite heavy and battery guzzlers. From tests found online, the i7-720QM loses out to the i7-620M when using certain programmes, as mentioned earlier. Might as well make it worth your money and muscle (to carry the heavy machine) by getting something more powerful.

And for the rest of us mortals...
Mobility first, performance second:
i7-640LM or i7-620LM. They are the most powerful low-voltage processors, and the best ultraportable laptops on the market use them.

Performance first, mobility second:
i7-620M, or if you want to save some money, i5-540M. If you want to save more money, you can consider the i5-430M.

Budget:
The i3 series is probably the way to go then.


Conclusion
Hope this helps you in choosing your new laptop. It took me many days of reading up online to get up to speed. Actually, I've stopped reading tech mags and articles since I got my first computer in 1998. In those days, Pentium II 266MHz with 32MB RAM was top end.

But if you don't need to upgrade now, you should wait for next year's models. Due to be out in the first quarter of 2011, they promise to be faster and more power-efficient.

In the end, I placed an order for the Thinkpad X201 tablet with an i7-620LM. After using a Thinkpad for the past 5 years, I don't think I can use any other laptop again. Love the keyboard, the trackpoint (aka the little red dot) and the overall asthetics. Hope it arrives in the mail soon!

Afternote:
Other important factors to your computer's speed would be the hard disk drive speed and the amount of RAM.
For the hard disk, try to get one with 7200rpm, or get a solid state drive (SSD) if you can afford it.
Get 3GB of RAM if you are running Windows 7 32 bit, and at least 4GB if you are running the 64-bit version.

How I learnt to love digital again

Until last week, I hadn't used my Nikon D40X for almost three months. The last time I did was when I took a couple of shots at the Apec Leaders' Meeting held at the Suntec City Convention Hall in November.

I'd actually thought it was the end of my D40X. I was already planning to replace it with a "pro" digital body. 

Then I bought a Nikon F3HP film camera on ebay (after one failed attempt) for a good price. Next came the problem of getting lenses to go with it -- because it's an old-school manual focus camera, I can only use it with old-school manual focus lenses.

The first to come was the Nikkor AIS 28mm f2.8, a legendary wide-angle that respected lens reviewer Bjorn Rorslett calls the best ultra-wide-micro-Nikkor, because it can focus as close as around 11cm from the front of the lens.

When I paired the diminutive lens with my tiny D40X (initially just to test for sharpness), it was like pure magic. To begin with, the 28mm is a joy to use, even though it's a manual focus lens. Like all old-school lenses, it's solidly built, with almost all metal parts, and the focus and aperture rings turned oh so smoothly. The combination balances perfectly and fits into any of my bags, including those that I use for work.

It has totally usurped the AFS 60mm f2.8 as my one-lens solution for the D40X. I can bring it anywhere. It's so light that I can barely feel the weight. It is super sharp at f2.8. (I got an excellent copy)

Meanwhile, the F3HP has arrived, condition just as described. But with the D40X rising from the ashes, I think I'm moving further and further away from film. While I enjoy shooting film, the tediousness of scanning and colour correction has taken almost all the fun out of it. Maybe I'll just use film for B&W from now on. Still got a few rolls of Kodak Ektar 100 to run through though. The F6 looks likely to go, sadly. Maybe even the 85mm f1.4.

Next lens to buy: A manual focus 50mm f2 or 35mm f2 lens, since the D40X is hogging the 28mm.
Next to sell: F6?

New Products Announced! Nikon D5000 and AF-S DX 10-24mm f/3.5-4.5G ED

Well I was eager anticipating the new entry-level DSLR from Nikon, and the just-announced D5000 looks like a worthy successor to the D40/40X/60. Some key new features I personally find useful, as compared to my D40X:
  1. CMOS sensor - ISO performance. Biggest improvement imho, reason enough to upgrade!
  2. 11 AF points - Very useful for shallow depth of field shooting
  3. Flip-out LCD with Live View - A huge boon for macro shooting esp. from low, low angles. And live view finally!
  4. New retouch options, including perspective control, square crop and colour outline! - Quite neat for quick editing on the go
The higher megapixel count is a bit of a bane though, esp. if you are doing RAW-editing on a Thinkpad X41. I don't think D-movie will be very useful either, but hey, you'll never know when you'll need it.

Probably a no-brainer for a first DSLR, but I'll probably wait and see how the pricing goes before deciding whether it is worth an upgrade.

As for the new wide angle, I think it is definitely worth looking at if you are searching for a lens in that focal range. A plus-point is that it takes 77mm filters... which is what you'd want to invest in now, if you plan to upgrade to better (i.e. more expensive!) glass in the future.
