Film camera review - Zorki 4K vs Fed 4

Blind Shots - From BELOW the hip!

Hello again, friends and passers by,
It's been a while since my last posting, but I have finally been able to manage to have some time to do some more photography work, including updating this blog and starting to work on my website which has been under construction for a good while.
Having had the day tottally free today, I thought to myself "Why don't you go and enjoy the day doing what you love most", so I packed my newly bough Fed 4 rangefinder which has ISO50 film in it (in fact, this Fed 4 is a stand in for a retired Zorki 4K, that ended up being autographed by the one and only, David Bailey). As I looked outside, I realised the light was not really for slow, ISO50 film so wanting to do some street photography, I packed my lovely Fujifilm S3 pro instead into my bag along with a Sigma 18-125mm, Nikon 50mm and 75-240mm lenses and off I had gone to do some street shooting. I wanted to try something new and hone my skills at taking blind shots - shooting from the hip - but as I found a bit awkward using this camera from the hip, I decided to set the 18-125mm lens to its widest, up the ISO to 1600 and just have it on my hand as if I was casually passing by and aim at subjects I found interesting without disturbing them making them lose all naturality. The camera was pretty much almost at my knee. I haven't dabbled enough in this type of thing, but I got some surprisingly interesting results and I sure will do this more often.
Check out this session here
There's also some new handheld street night photography here , using my Samsung GX-20 for anyone interested to see how it handles in the dark at high sensitivities, or just to appreciate the wonders of the night through the lens. Enjoy!
Until next time,
Luis

It's been a while...
Anyway, being the beggining of April and given the current world financial crisis, it was impossible to ignore the G20 protests, which I had chance to photograph. It was the first time I have found myself in a situation of such tension as a photojournalist and frankly I wish I didn't snap away like a robot as I filled up my cards before the major clashes. I have a handful of photos of the clashes but in a way the photos I have show another side to the protests, a side that shows that for the most part it was a peaceful protest, an intense and tense one, but peaceful. I believe that a small faction decided to wait until the police started to open up the streets to wreak havoc and start a riot. Nevertheless, it was perhaps clearer than ever before the discontent of the masses with the increasing divide between classes, the global economics and climate issues, that the time for change is now.
And now, for some photos (click the set below, more to come):

Until next time,

It's here!
___________________________________________________________________
Introduction
Samsung/Pentax/Samtax
The Samsung GX20 is pretty much a Pentax K20D but according to Samsung the image processing is different and better.
It takes Pentax KAF mount lenses (of which I have near to none at the moment, apart from a Centon 50mm f1.7 which is more of a paperweight and a 70-210 of the same brand and serving the same function) and Samsung has their own version using Schneider-Kreuznach glass. The 18-55 lens is not brilliantly sharp but for non specialist use does it's job. The camera is very very solid indeed and I was already very impressed with it when I first used it but having spent longer time with it and comparing it with my other DSLRs (KM 7D, Fujifilm S3, Sony A700,Sigma SD10) fares very well and I am even tempted to consider it a notch above all in this department. I wish I could compare it with a more current crop of DSLRs myself, but the word out there is that it fares very well again anyway. While I feel the need to add a battery grip to my A700 (except the other ones which have a grip), I do not feel the same about the GX20. It feels well balanced and very comfortable, with the body finish adding to this feel.
Features
This is an area where I was second time awe struck. From the usual picture styles to AF fine tuning it felt as if this was the case that this was someone's first camera, they wouldn't be asking for more. It is a feature rich camera and what particularly excited me was the fact that I could process my RAW files in camera (as I am a RAW shooter in any situation), so I could have a JPEG of only the pictures I would have to either send or share, ready to go. I wished my other cameras had this to save some space in the card.
While this was exciting, this is in my opinion the feature that at the same time hampers the camera's image quality but only slightly and I will expand on this in the Image Quality section.
Performance
Performance is on the whole good, but the AF tends to hunt or hesitate a little in lower light. I do not know if this is because of the cheaper kit lens, it is likely. In daylight I found the AF very good with this lens. Reviewing images can also be slow, but given the size of the images (and the fact that I use a S3pro too which is no speed champ either in this department) I did not find this a turn off, also because you can cancel review at any time by pressing the shutter button to go back to shooting.
If you choose to process your RAW in camera then you will have to wait for this to finish but it doesn't take long. In any case, this is a feature I would leave for when I finish my shooting.
Image Quality
This is an area where this camera unexpectedly excels with its 14.6MP even at higher sensitivities.
Initially I had my reservations when I was looking at the JPEGs from the camera. For some reason, it seems that the camera introduces some chroma noise in the JPEGs when it either shoots them or you process them in camera. While ISOs from 100-400 are very good, you start seeing chroma noise at 800 and increasingly above.
But do not despair. Putting the RAW (DNG) files through ACR really makes them shine. You see a very pleasing, more luminance, film like noise at higher ISOs and the images are also very clean, with good sharpness at these sensitivities, which for a sensor of 14.6MP is not easy (and with the kit lens that it came with). I would not hesitate to pump up the ISO if there's ever the need for it.
In this department I am very satisfied, because for me what really makes or breaks my choices for a camera is what it outputs and this camera does not disappoint even the most demanding photographer.
Conclusion
So this concludes my initial thoughts on the camera. If this is what Pentax and Samsung are playing with now, I personally see no reason for this duo to come out with even more technically impressive stuff and join the big two which are becoming the big three now (with Sony having played out very well and I even see some using Sony now in the midst of the sea of Nikons and Canons out there). Perhaps the challenge is financial (and also the fact that the AF lens collection is a bit limiting on both parts and 3rd party dependency is not bad but not very good either)but that's something for a different discussion.
I believe with a little AF improvement and perhaps adding another 3-4fps to the drive (making it 6fps), this dynamic duo can come up with a true alternative(s) in the market. The image quality is certainly there. Let's see what happens next.

So yes, I am thoroughly impressed :)
Some samples will be posted on my flickr.com page here .

Amateur Photographer Magazine's On Assignment Feature
Well, this made my week I have to say, seeing not only my photos published in Amateur Photographer Magazine in the "On Assignment" feature, but also win the competition for Picture of the Day. It's always great to get recognition among your peers and AP provided a great day which I thoroughly enjoyed along with the opportunity to enjoy an unusual and fun event, Jousting at Hever Castle, a recreation of medieval jousting by The Knights of Royal England (www.knightsroyal.co.uk) .
You can see some of the shots that are not in the magazine here , but the set does include the winning shot.
Many thanks to AP and especially Garry McNamara and Gemma Padley for their guidance and support.
Until next time,

Nikon launches world first video capable DSLR

On a personal view, I was never a friend of the all in one device, I prefer to have dedicated devices for a given task as they tend to perform better. Having said that, the higher quality of photo lenses coupled with a video capable device may turn things around.
Nevertheless I see the video capability of the D90 as a lesser benefit, a bit of a gimmick, the excitement for me is the inclusion of Nikon's acclaimed 12.3MP CMOS and a very useful 4.5 frames per second capture (for photojournalistic work).
Kudos to Nikon for including these features in an enthusiasts model at this price point.

UCL building Roman Numeral blunder...
It's been a while since I have posted anything here, I have been a busy man, I launched my website (which I am still working on the interface but has somework on display)among other things I had the chance to take part in a user review with What Digital Camera magazine and a "On Assignment" section for Amateur Photographer Magazine.
Anyway, I was out with my camera today and I was feeling a bit uninspired so I passed by the UCL building behind Warren Street and took a shot of the wrong Roman numerals in one of the buildings as I was wondering if anyone else had noticed that (as I work in that area for a while I was always amazed nobody has said or done anything about it) and a bit shocked that an educational institution like UCL could make such a blunder.

Better change that quick as it won't do any favours to UCL to have that there for any longer.
Until next time,
Luis

Old Man Winter is back!
It seems there's no escaping it...Spring is supposed to be here as of thr 20th of March but we keep on being battered by cold,snow,hail and whatever else the sky can throw at us. I gathered my guts to brave some cold today and went out to take some photos, (as I haven't done so in a while) and found out the possible explanation for this Spring delay...Old Man Winter is out and about!

Linux and Photography - a rare combo...
So, I decided for a gradual move into Linux and for that, I decided to try Linux with it's own version of Photoshop...GIMP with UFRAW plugin.
I have to say I was pleasantly impressed. GIMP may not be as polished interface wise as Photoshop, but all the tools you need are there, one just needs to get used to the interface while the UFRAW plugin for camera RAW files offers all the control a photographer will ever really need. The only minus is that it seems that it does not perform denoising on the RAWs (perhaps it is a plus as it really shows as your camera performs), I still have the feeling that UFRAW outputs somewhat noisier files. Having said that, I have converted Sigma X3F files with UFRAW with very good results. Here are some examples:


Despite the second example showing some noise which resulted from the exposure correction, the results are perfectly usable at full resolution.
For me this is a big thumbs up and a step closer that transition from Windows to Linux ( which will allow me to do more with much less usage of system memory and CPU).
Until next time,
Luis

Woody was around...
But this fella was difficult to shoot, he liked to keep his distance, as such the pic below is only a resized crop. Taken with my Minolta 7D and Sigma 70-300mm APO DG.

Until next time,

The Sony A700: Finally, a real upgrade to the Minolta 7D
Back is Minolta like design,build and layout, Minolta’s Anti-Shake system reincarnated again as SuperSteadyShot and what seems to be some 12 very clean megapixels (using CMOS rather than CCD as on the 7D). The Sony adds in this package for A-mount users its DRO technology, offering extended dynamic range as in camera option and environmental sealing. Performance has vastly improved, with 5fps in consecutive mode so you don’t miss those crucial moments. In short, the A700 seems like a vastly improved tool over the already excellent Konica Minolta 7D. I had the chance to handle one and see the results and the camera feels quite familiar, apart from the menus, but still no big deal, its something you can get used to very easily.
It finally feels as if Sony can be taken seriously as a camera maker, the A700 means business and it has Minolta DNA all over it.
I think I know where my money is going next.
